1 Executive Summary
1.1 Project Background
Energy storage is a key source of flexibility that can help address some of the challenges associated with the transition
to a low-carbon electricity sector. Storage, as identified by the Smart Grid Forum, is one of the key smart interventions
likely to be required in the future smart grid. However, challenges in leveraging the full potential of storage on
distribution networks to benefit other industry segments, and a lack of scale demonstrations are currently hampering
the efficient and economic uptake of storage by the electricity sector.
The Smarter Network Storage (SNS) project is carrying out a range of technical and commercial innovation to tackle
these challenges and facilitate more efficient and economic adoption of storage. It is differentiated from other LCNF
storage projects through the demonstration of storage applications across multiple parts of the electricity system,
including the distribution network but also outside the boundaries of the distribution network. By demonstrating this
multi-purpose application of 6MW/10MWh of energy storage at Leighton Buzzard primary substation, the project is
exploring the capabilities and value in alternative revenue streams for storage, whilst deferring traditional network
reinforcement.
The project aims to provide the industry with a greater understanding and a detailed assessment of the business case
with the full economics of energy storage, helping to accommodate increasing levels of intermittent and inflexible low
carbon generation. The project was awarded funding of £13.2 million by Ofgem, under the Low Carbon Network Fund
(LCNF) scheme in December 2012 and will last four years, from January 2013 to December 2016.
1.2 Summary of Progress
In this reporting period the project has completed the construction and commissioning of the Smarter Network Storage
facility, making it Europe’s largest battery owned by a network company. Despite some issues encountered during the
commissioning process, the facility is now operational and is completing testing ready for the System Integration
Testing phase, however there remain outstanding system defects that need further investigation which are covered in
more detail later in Section 2.1.
Figure 1: The site in May 2014 (left) and later in November 2014 with landscaping and fencing (right)
During this period Work Stream 1 (WS 1) has seen a vast effort in completing the civil and electrical construction work
at Leighton Buzzard and continuing into the testing phase. All installation work has been completed and the Electrical
Storage Device (ESD) has passed site acceptance testing, with 6MW of power exchange now demonstrated and at
time of writing is ready for System Integration Testing to begin.
During this period Work Stream 2 (WS 2) moved from software design phase and entered into development and testing
phase. The software suppliers completed development and their testing; in turn the project team integrated the
software solution and carried out acceptance testing using UK Power Networks’ infrastructure. Integration testing is in
progress to make the solution ready for trails.
Workstream 3 (WS 3) has identified a range of individual trials to demonstrate the storage capabilities and various
value streams. A comprehensive suite of detailed trial design documents has been completed which describe the
Page 3 of 54
hypotheses, technical requirements, processes, risks and expected outcomes. This includes pre-trial tests which
chronologically sit between commissioning of the energy storage system and handover of the software and hardware
infrastructure before the kick-off of the trial phase once the storage is operational. The pre-trial tests aim to serve as
confidence building tests as well as system integration tests for the various software and hardware sub-systems. The
initial trials to be carried out will be network-related, which have been designed by Imperial College London, and
support the work assessing the contribution to security-of-supply of shared-use storage. The pre-trial designs and the
initial network-related trial designs have been drafted and are awaiting confirmation of the exact execution dates and
the PI naming tags before completion, which are both expected in early January 2015 after completion of the full
commissioning of the SNS hardware and software infrastructure.
The key focus and deliverables from Workstream 4 (WS 4) during the period has been the completion of a report
detailing Commercial Arrangements for Integrated Use of Flexibility (SDRC 9.3 report, SNS4.6) together with the
completion and signing of agreements with Smartest Energy and Kiwi Power. This together with a confidential report
compiling other relevant evidence, mainly meetings and workshop notes, forms the evidence demonstrating the
successful completion of successful delivery reward criteria 9.3.
1.3 Risks and Issues Summary
Procurement Risks and Issues

RTU firmware had to be upgraded to cope with DNP3 protocol – This was because GE documentation was
inaccurate, as a result additional consultancy was required from GE to resolve this at an extra spend of £3,100.

Vodafone & BT data communications issues – Vodafone made a number of errors during the delivery of the
VRF connection at Leighton Buzzard, which is now completed. This resulted in delays in connectivity tests and
unplanned resource utilisation.
Installation and Other Risks and Issues

11kV switchgear joggle-box error – There was an error made by a sub-contractor of the supplier of the 11kV
1
switchgear that required the replacement of a joggle box required to extend the existing 11kV switch-board.
This was completed behind schedule but the supplier agreed to cover all additional costs.

Samsung SDI rack BMS error – Samsung SDI advised that the BMS circuit board they had supplied had a
fault that caused intermittent operation; this was identified on another installation. Replacement circuit boards
were supplied to resolve this issue by Samsung SDI and installed by S&C Electric and their subcontractor
causing some short delays.

Communications Interference issues – Electromagnetic interference causing loss of communications on a
CAN-BUS interface between the batteries and the battery management system caused significant delays,
meaning the completion of the commissioning was behind schedule. This has been rectified by improving
software resilience, replacing the cables with better screened cables and the installation of physical
containment. There are some further issues relating to circulating currents within the building that are still
under investigation at the time of writing, but are expected to be resolved within the next reporting period.
Towards the end of this reporting period and moving into the start of the next period full end to end integration testing
of the system will be carried out. Naturally work during the design stages has attempted to mitigate all problems that
could be encountered in enabling the different sub-systems to work together; however as with all innovative work
involving first-of-a-kind software and hardware platforms, there is an elevated risk of unexpected issues arising that
could cause further delays to the programme.

1.4 Learning and Dissemination Summary
The SNS project continues to generate and capture key learning, which in this reporting period has predominantly
materialised from the installation and commissioning of the storage facility and through the process of implementing
novel commercial arrangements for operating the storage in the markets.
The key learning outcomes are summarised below, with further information available in Section 7.1:

Building a large scale ESD in a building presents different challenges to a containerised solution

The application of some standard charges as part of The Electricity Supplier Obligations could lead to
disadvantages for storage operators, and double counting of industry charges;

The application of some distribution-related charges do not always reflect the potential value or capability that
the storage system can offer;

The firmware of Remote terminal Units (RTUs) should be up to date prior to testing;

Improved understanding of storage amongst energy suppliers and standardisation of energy supply contracts
is needed to facilitate the adoption of energy storage

DNOs may need to contract or develop additional expertise in DC design
To ensure that the project is continually capturing learning resulting from the project, regular workshops involving the
project team are scheduled, outside of other governance and project meetings, which provides a forum for specifically
discussing and capturing new learning.
In addition, the partner forums, which have been held on 28 July and 18 November, provided an opportunity to discuss
and capture any additional learning with external project partners.
As part of WS 5, which is dedicated to learning capture, dissemination and stakeholder engagement, the Knowledge
Dissemination Roadmap has been reviewed and updated to reflect the evolving plans for engagement and
dissemination by the centralised learning and dissemination team.
The following internal dissemination activities, project–related events, communications and engagement have

2 Project Manager’s Report
This section describes the progress made on the SNS project in the reporting period June 2014 through to December
2014, including the key milestones and deliverables met, any issues encountered, and provides an outlook into the
next reporting period through to June 2015.
2.1 Progress in the reporting period
2.1.1
Project resourcing and governance
2.1.1.1
Project Resourcing
The project team remains unchanged since the last reporting period, and has continued to leverage expertise in the
delivery of civil and electrical construction projects through UK Power Networks’ Capital Programme Directorate, and
our appointed Principal Contractor; Morrison Utility Services.
The following organisation chart, in Figure 3, shows all the allocated resources within the SNS project structure as of
December 2014.
Figure 3: Smarter Network Storage organisation chart
Engagement continues with the core project partners both through ongoing work, and at a more senior level through
the Partner Forums. A Partner Forum meeting was held on 28 July, where an update was provided on construction and
installation progress and the activity around SDRC 9.3 was discussed.
Page 7 of 54
A second Partner Forum was also held on 18 November at the storage facility in Leighton Buzzard. This provided our
project partners an early opportunity to have a tour of the storage facility, and discuss further the trial work to be carried
out in the next phase of the project.
2.1.1.2
Project Governance
The governance model, as described in the previous six month progress report, is unchanged and continues to be
operated by the Programme Management Office. The model identifies two distinct streams: Solution Governance and
Project Governance and helps to ensure a focus on developing effective technical and commercial solutions to meet
learning outcomes, as well as an effective structure for ensuring the overall solution is delivered on time, to budget and
to the appropriate quality.
Further information on this governance model, including supporting project control and reporting mechanisms, is
documented in the SNS Project Handbook (SNS5.4).
A number of additional processes have been developed to cover specific activities relating to operating the ESD during
the trial phase. These are listed below, but include processes for developing and agreeing trials, reconciling and billing
from the delivery of commercial services and internal reporting.
Key issues encountered
No significant issues have been encountered in this area during the reporting period.
Key deliverables

SNS 3.16 – Trials Process

SNS 3.17 – SNS Trials and Operation Invoice Billing Reconciliation Process flow
2.1.2
Project Planning
As highlighted in the previous 6-month progress report, the current reporting period has represented a critical period in
the project with a significant amount of activity occurring as the construction and commissioning took place, in parallel
with the development and testing of the IT solutions.
More regular progress reviews and workstream-level project planning has therefore continued throughout this current
reporting period to ensure progress is closely monitored and plans updated accordingly.
Several issues encountered during the commissioning of the storage facility have led to a delay of approximately eight
weeks in trial start, which are further described in Section 2.1.3 This has required ongoing re-phasing of various
dependent activities, but will not affect the level of learning generated from trials or subsequent key milestones due to
the flexibility and design of trial arrangements in the following phase. An updated high-level summary of the SNS
activities and deliverables achieved in 2014 is provided below in Figure 4.
Page 8 of 54
Figure 4: SNS 2014 key deliverables summary
Similar to the previous year, a strategic planning session was held with the project team on the 7 November 2014. This
provided an opportunity to review the objectives and structure of the project team ahead of the transition to the
operational and trial phase, identify the priorities and core work packages for 2015 and any additional dependencies
and risks for the year.
No significant issues have been encountered in this area during the reporting period.
Key deliverables
No new deliverables have been developed in this area during the reporting period.
2.1.3
WS 1 – Energy Storage Hardware
WS 1 covers the design and development of the storage system; hence many of the activities in the current stage of
the project are encapsulated within this WS. The focus within this reporting period has been the installation,
commissioning and testing of the energy storage system (see Figure 5) within the new building at Leighton Buzzard,
along with the additional equipment and network modifications required for its safe and effective integration. Detailed
preparations have been made for the operation of the system including the preparation of user guides and training
materials; delivered to UK Power Networks staff in the local area as well as to network control engineers and other
relevant staff.

2.1.3.1 Design & Planning
Engagement with Central Bedfordshire Council has been sought during this reporting period on some aspects relating
to the site completion. Specifically this has included the approval of the appearance of a low fence along the edge of
the land being leased to the council for the use of the local residents. This includes the provision of ongoing access for
the council and the Environment Agency to maintain the land they are leasing and the Clipstone Brook respectively.
At the close of this reporting period the site will have been de-mobilised and the landscaping completed. The
landscaping is in progress at time of writing; having been delayed slightly by the warm autumn. The semi-mature trees
needed to be dormant before they could safely be moved.
Documents have been prepared to ensure that upon the completion of the site works the requirements of the Section
106 agreement with Central Bedfordshire Council are met. This includes the lease to the land that is being made
available for the use of the local residents, as shown in Figure 12; transfer to the council of the land they requested
alongside the Clipstone Brook, as shown in Figure 6; and a payment to the council to support the maintenance of the
land being leased to them.

Figure 6: Provision made in fencing and land alongside the Clipstone Brook past the site.
During this period there were some late design changes that were implemented in the project. Although all relevant
stakeholders had been consulted during the design phase some late requests were made to add an additional 11kV
circuit breaker to the primary substation bus-bar and an additional Ring Main Unit. These are being used to support the
11kV network in the area by enabling additional 11kV circuits to be run from the primary substation and to provide
additional network flexibility. Although the work for this has been carried out by the SNS project the funding for all the
work has been provided separately
2.1.3.2 Construction
On 15 May 2014, in the last reporting period, the interior of the new building was handed over to S&C Electric to install
the batteries, power conversion systems, fire suppression system and cooling equipment. The first battery deliveries
from Samsung SDI arrived on 19 May. These were the first of 14 shipping containers of equipment from the Korean
supplier.
Due to the difference in levels between the ground, a container on a lorry trailer and the building loading bay an
intermediate level scaffold platform was constructed, as shown in Figure 7. This allowed the palletised equipment to be
easily offloaded from the containers onto a scissor lift that could raise them to the level of the building loading bay,
reducing the time taken to offload each container and ensuring employee safety in the process.
Figure 7: Completed scaffold loading platform and high level DC bus-bars being assembled.
The first elements to be installed were the DC bus-bars, hung from the high level structure of the building above the
position of each of the battery arrays (see Figure 7). The battery rack frames were then positioned and bolted together
and to the floor to create a stable structure. Once these frames were in place they could be populated with the battery
Page 11 of 54
trays themselves. This process carried on until early July, with the last array then completed on 18 August following the
delivery of the Power Conversion Systems (PCSs).
Following the completion of the battery arrays the different cable supports, cabling and ancillary equipment were
installed, as shown in Figure 8. The control cabling on the battery racks was installed between 22 July and 29 August
with the power cabling to connect the battery trays together left to the last stage before testing. This was done to
minimise the risk posed by the energy stored within the batteries by keeping them isolated in as small units as
possible.
The PCSs arrived in sections (see Figure 8) on 31 July from the USA and re-assembly was completed on 6 August.
These were then positioned with the transformers in the SNS building. Work then commenced on re-assembling them
from the shipping splits and connecting up the main and auxiliary cables.
Figure 8: PCS assembly on site and DC cable supports and termination boxes.
During this time further work was done inside the SNS building to install the fire suppression system and the heating,
ventilation and cooling system. These involved the mounting of acoustic louvers, fans, ducting, vents, gas sampling
pipework, fire grade cabling, control cabling and control boards, some of which are shown in Figure 9.
Page 12 of 54
Figure 9: Fire suppression bottles and a ventilation louver during installation.
Outside the building, work commenced in earnest during June to stitch the energy storage device into the local 11kV
network. From 11 June the CDM construction site was extended to include the existing Primary Substation adjacent to
the SNS building. A scaffold loading bay was erected to allow equipment to be safely delivered to the building as it is
also raised above the site flood level.
Using this platform on 16 June new 11kV circuit breakers were delivered to extend the existing switchboard and enable
the connection of the energy storage device (see Figure 10). Between 17 June and 1 July the new auxiliary battery
systems, automatic voltage control panel and Remote Terminal Unit (RTU) were delivered. As it is not possible to run
multiples of these systems, significant effort was required to integrate these with the existing equipment so that the new
unit could cope with the requirements of the energy storage system.
Page 13 of 54
Figure 10: New 11kV switchboard extension and demonstration of the new RTU.
Due to the increased auxiliary demand and the requirement for this supply to be secure the existing padmount
substation (providing low-voltage supplies) was removed and replaced with two new distribution substations on raised
plinths. Construction of the bases and access platform began in mid-July and was complete on 27 August. The first
new 11kV cables were installed on 21 August with the last cables on 9 September and all joint bays reinstated during
the first two weeks of October. The changes to this area of the site are shown in Figure 11.
Figure 11: Before and after of the area within Leighton Buzzard 33/11kV site with the local substation providing the site
auxiliary supplies.
Page 14 of 54
Once the majority of this work was complete UK Power Networks’ security contractor mobilised to site to install the
permanent security. The new building is secured to current company standards but the security at the adjacent existing
site was upgraded to protect the network connection of the energy storage device. This minimises the likelihood of
anyone interrupting the supply with potential network security or commercial implications and secures the high value
assets installed. During the current period there was a break in to the site on 17 September causing damage to the site
office. Nothing was taken and no damage was done to the SNS building itself or equipment contained within it.
During the week commencing 6 October the site management and facilities were moved into new cabins to enable the
original cabins to be removed and the land to be landscaped prior to leasing the land to the council. The hoarding has
also now been removed along with the hard-core that had been laid to form a working surface. Topsoil that had been
stockpiled from the original site clearance could then be distributed to make up the ground levels and provide for
planting.
Figure 12: Levelling and preparation of the ground to be leased to the council for the use of the local residents.
At time of writing the planting is complete and, by the close of this reporting period, the site will be completely
demobilised. It is planned to leave a single cabin on site to provide a safe room for meetings and to facilitate visitors to
site to support the dissemination of the learning from this project to other DNOs and the wider energy storage industry.
2.1.3.1
Testing
The initial 11kV energisation of the SNS switchboard took place on 12 September with sequential tasks following to
test the step-up transformers and AC side of the Power Conversion Systems. This formed part of a detailed testing
programme governed by the SNS1.3 Testing Strategy document.
The electrical testing continued largely without incident including full reactive power tests until the testing of PCS DC
side and transfer of power to/from the batteries. This is described in more detail in “Key Issues Encountered” below.
The ESD was broken down into its constituent units and commissioned by PCS and by Battery Energy Storage Device
Manager (BESDM – section of the ESD). The PCSs were checked following re-assembly then their auxiliary power and
control systems were tested. The PCS inverters were then tested to their full reactive power capability before control by
the BESDM devices was attempted and real power testing.
For each BESDM (representing two battery arrays) the communications were tested first, then basic control of the DC
contactors then initial charge and discharge tests. Following the resolution of the key issues (described below) the
batteries were then put through a “State of Health” calibration to confirm the batteries could be charged/discharged fully
and an endurance test, where any poor cell performance would be detected. Once each of the six BESDM devices and
their respective battery arrays were tested in this way the communications were enabled between these and the
Battery Energy Storage System Manager (BESSM) controller. Tests on the whole ESD could then be carried out.
The ESD system tests, operating in each mode required driven by the battery management system BESSM, are
complete. This marks the completion of the Site Acceptance Tests of the equipment supplied by S&C Electric and their
sub-contractors Younicos and Samsung SDI. System Integration Tests including other aspects of the IT and
forecasting system covered in WS 2 can then be carried out at the end of this reporting period through into the start of
the next one.

Aside from the main electrical systems the ancillary systems were also all thoroughly tested. In order to sign off the fire
suppression system it was required to test the ability of the building to maintain air pressure to a certain level. This
ensures that if released the suppressant gas remains in place for long enough to suppress a fire. The building passed
this test at the first attempt.
The heating ventilation and cooling systems were tested to ensure the appropriate responses to temperature change
are made. The auxiliary supplies, metering and communications systems were also thoroughly tested.
2.1.3.2
Health and safety considerations
During this reporting period there have been two areas of focus regarding health and safety considerations. Firstly has
been the planning and management of the on-site construction work. Secondly has been the preparation to bring the
energy storage device into operation and preparing the business to receive it.
During this time there have been over 21,000 man-hours worked on site from S&C Electric and their subcontractors
alone with regularly 50-60 people on site at any time. For an extended period the site has been operating 12 hours
days Monday through Thursday to enable the efficient use of staff who have travelled to the area for the work and are
staying locally. This has required the full time attendance of one or at times two site mangers from the Principal
Contractor Morrison Utility Services (along with site management and supervisory staff from S&C Electric and their
subcontractors) to ensure that the work is co-ordinated and staff are controlled. At time of writing there have been no
Lost Time Incidents on the construction of this project.
The follow are some positive comments received by Morrison Utility Services from visitors to the sites through their
feedback cards:

“Well organised site. Very good induction, clear, balanced and effective. Site controlled, partitioned and zoned
for access control and work activity. Impressive generally, taken guidance for our systems”;

“Site person in charge gave me thorough site induction. All my questions were answered. I found the induction
was very descriptive and was presented excellent”; and

“Clear instruction, good visual aid for induction. Presentation Highlighted to risks on site, very good”.
On 9 July the site was audited by the Considerate Constructors Scheme receiving a very good score in the final report.
The specific feedback points were discussed with Morrison Utility Services to identify where further improvement might
be achieved.
Figure 13: Considerate Constructors Scheme banner displayed prominently on the construction hoarding.
During the build phase specific labour and manual handling saving devices were developed including the scaffold
platform discussed above and a device for the safe and efficient installation of the battery trays into the racks on site.
In preparation for the operation and ownership of the ESD by UK Power Networks significant effort was put into
developing approved procedures for the new equipment. This included discussions with the internal Health & Safety
teams and engineers as well as the suppliers involved. Discussions were also had with other DNOs to incorporate their
Page 16 of 54
learning form similar projects. Acknowledgements specifically go to Ian Lloyd from Northern Powergrid for supplying
and discussing their procedures, in addition to engagement from the Energy Storage Operators Forum.
Version 1 of an Engineering Operating Standard (EOS), “EOS 09-0074 Energy Storage Device at Leighton Buzzard”
was approved on 22 October. This first version contained all available information at the time of commissioning, which
was required before the system could be brought into operation. A revised version is planned for re-approval in the
next reporting period with the inclusion of final details incorporating as-built photographs and screen shots from control
systems that were not ready for inclusion in issue 1. This document becomes the reference document for site visitors,
ESD operators and network control engineers who have to interact with the ESD and points towards the various subsystem user guides where applicable.
At time of writing some initial training material has been developed to use to train both the local area engineering staff
and the network control engineers, those who might interface with the ESD on a day by day basis. This consists of
presentation slides and spoken training describing the system and operating requirements along with the issue of a
copy of the EOS document. Plans are in place to develop interactive training including guidance videos on the specific
tasks involved which it is expected will be produced in the next reporting period.
At time of writing as the construction work is coming to a close our CDM Co-ordinator is working closely with all the
parties involved in the project to ensure that a detailed and accurate Health and Safety file is compiled for the work on
site. It is expected this will be largely complete by the end of this reporting period with the final details closed out in the
next period.
Key Issues Encountered
There were several issues encountered during this reporting period, as might be expected. These are detailed below in
turn.
Upon initial preparations to position the battery racks in the new building late May/early June 2014 it became apparent
that the cast floor slab was not sufficiently flat for all the racks in an array to site level. This was resolved by using steel
packing shims to sit underneath the rack frames to ensure they could be correctly installed and would be supported at
all points required. Detailed investigations revealed that although a few sections of the floor were outside design
tolerance, even floor sections within the design tolerance were not sufficiently level. Tighter cast concrete floor
tolerances or the installation of fixing rails would be required for future applications. This would need to be considered
in future designs with regards to flexibility and future upgrades within a fixed building.
To make the 11kV connections to the existing primary switchboard work was required to extend the existing Reyrolle
LMT board with new HSS Eclipse circuit breakers coupled together with a bus-bar joggle chamber. This was a critical
task that had been done multiple times before so was not considered a high risk to the project. It transpired that a subcontractor to HSS had made an error in their design and provided an incorrect joggle chamber, stepping the new
switchgear too far backward. This meant that the back of the gear was not correctly supported and the operating
handle fouled the side of the joggle chamber, preventing correct operation. Once HSS were made aware of this issue
they took steps to construct a new joggle chamber in a reduced time-frame and covered all UK Power Networks costs
incurred in the replacement. This delayed the 11kV re-configuration work and particularly the modification of the SNS2
feeder CB but these delays were managed within the tolerance available in the site work programme.
There were two delivery issues relating to the novel equipment supplied to the project. The batteries supplied by
Samsung SDI were shipped with two separate palletised stacks of batteries on top of each other within the shipping
containers. Due to the motion in transit and the fact that the pallets were not tightly held in place the top layer moved
during shipping. It was the not possible to off-load them directly on site due to the equipment available; requiring
double-handling of equipment and some off-site storage. The second issue was a delay in shipping. Due to some
problems at their Wisconsin facility S&C Electric were not able to carry out the final testing and ship the PCS units until
seven weeks after the original planned ship date. The installation of these was not on the critical path of the project but
eliminated any opportunity to complete the installation work on site early and carry out extra testing. It also required
one of the battery arrays to be left out to allow for the delivery of the PCS units to their final position.
We were advised on 28 July 2014 Samsung SDI had identified (on another installation) a problem with their rack BMS
circuit boards. They had designed, manufactured and tested replacement circuit boards that were shipped to the UK for
Page 17 of 54
installation. This caused a small delay in the work on site that was within the project contingency; none of the
associated costs were borne by UK Power Networks.
By far the biggest issue encountered within WS1 during this reporting period came during the initial real power testing
of the batteries. Due to the time and logistic constraints it had not been possible to bring the batteries and PCSs
together for testing until the site installation (one is manufactured in Korea, the other in the USA) and we were aware
this presented an additional risk to the testing phase.
During the initial “real power” tests, significant problems were identified with the communications over a CAN-BUS link
between the Younicos Battery Energy System Device Manager (BESDM) PLC and the Samsung SDI battery rack
BMSs. These were the first tests to use the “DC chopper” side of the PCSs and to charge/discharge the batteries. This
affected all the battery arrays to varying degrees and resulted in the inability to run any further testing.
Following some initial investigations on site that determined this was an Electro Magnetic Compatibility (EMC) issue an
expert from TUV SUD, a specialist EMC testing and consultancy practice, was brought in to carry out detailed testing,
assessment and to provide recommendations. Obtaining sufficient measurements was a challenging issue due to the
ESD only being able to operate for short periods before tripping off due to the comms issue and requiring resetting.
In parallel with this testing, investigations into the components involved were carried out. It was confirmed they were all
CE marked stating tested compliance with the EMC directive and the factory test reports were assessed. It was
determined that the test reports were showing compliance and that the issues were therefore most likely to stem from a
result of the scale and specific nature of the installation situation and connecting cabling.
Initial recommendations from TUV SUD included adding additional EMC shielding and containment as well as
changing the cabling used for the CAN-BUS to screened cables (it transpired that the original cables supplied by
Samsung SDI were not screened). Implementing these changes, along with some software updates to improve error
rejection and resilience, allowed testing of the ESD to resume. At time of writing more detailed investigations are still
underway, however the full 6MW of the ESD has been successfully operated over a period of several hours and the
overall impact to UK Power Networks has been approximately a six week delay.
Once testing resumed following the rectification of the EMC issue some other unexpected performance issues have
been identified. Part of this has been traced to some errors in the installation leading to circulating currents, which may
also be exacerbated by the unique nature of the installation in a raised, purpose-built building but as stated above
further investigations are underway and it is expected to have this resolved early in the next period.
Figure 14: Testing of the CAN-BUS signals
There have been additional issues encountered around the level of audible noise in the PCS/Transformer room while
the ESD and the cooling system is in operation. This restricts the ability of people to be in this room during operation
without hearing protection.
It was noticed during the autumn weather that there were a few places where the structure of the building housing the
battery was letting in water. This was however sufficiently clear of all electrical equipment to not present a safety
Page 18 of 54
hazard. It was identified that where the ends of the Kingspan cladding were hidden behind a piece of trim these were
not all completely sealed, allowing the wind to blow water in through the join. The whole building was checked and the
issue was quickly resolved by Morrison Utility Services.
2.1.4 WS 2 – Smart Optimisation & Control Systems (SOCS)
WS 2 is responsible for managing the design, development, testing, integration and deployment of the end to end IT
solution; Smart Optimisation and Control System (SOCS). This platform will manage the shared-use of the storage
across multiple applications, whilst ensuring network security is maintained. The SOCS solution comprises two distinct
sub-systems, the software hosted within UK Power Networks’ corporate IT environment, called the Forecasting,
Optimisation and Scheduling System (FOSS), delivered by AMT-SYBEX, and the control software co-located with the
storage at site, called the Energy Storage System (ESS), delivered by Younicos on behalf of S&C Electric.
Progress against plan
During this period WS 2 entered into the software development and IT infrastructure implementation phase.
Software
The SOCS solution is made up of:

Forecasting, Optimisation and Scheduling System (FOSS) – built on AMT-Sybex’s various Affinity Suite
modules

Energy Storage System (ESS) developed by Younicos and S&C Electric on a Zenon SCADA platform. ESS
consists of the following functional composition:
o
Battery Energy Storage System Management (BESSM)
o
Battery Energy Storage Device Management (BESDM)
o
Storage Management System (SMS)

ENMAC – UK Power Networks’ Network Management System

Remote Terminal Unit RTU

PI – UK Power Networks’ data warehouse

Enterprise Service Bus (ESB) – UK Power Networks’ IBM Message Broker ESB (WebsphereMQ)
As per the agreed design and approach defined in SDRC 9.2 (Confirmation of the Smart Optimisation and Control
System design) the suppliers produced the technical specifications for each module; developed the code and tested
the software prior to delivering into UK Power Networks environments. The diagram below is an extract from the SNS
Testing strategy document (SNS1.3).
Page 19 of 54
Figure 15: Testing life cycle
The SOCS solution has been tested using the above approach, where the supplier demonstrated evidence of System
Testing and UK Power Networks witnessed the Factory Acceptance Test (FAT), using the scenarios were defined by
UK Power Networks and Newcastle University. Successful exit from FAT enabled the supplier to deploy the solution
onto UK Power Networks infrastructure in a controlled manner. Each deliverable was then Site Acceptance Tested
(SAT) by replaying the FAT scenarios on ‘Production to be’ environment, these tests were conducted by UK Power
Networks and/or the supplier based on the nature of the test.
At time of writing the SAT of the SOCS installation is complete and the project team are ready to commence System
Integration Testing (SIT), Non Functional Testing (NFT), User Acceptance Testing (UAT) and Operational Acceptance
Testing (OAT). These all use test plans/cases developed by UK Power Networks and Newcastle University. Through
all the testing phases, defects were identified, captured and tracked using UK Power Networks defect management
tool (IBM Rational Rose). The priority and severity of each defect was agreed by all parties through defect
management forums and subsequently released using the above testing model (shown in Figure 15). Often a number
of test cycles iterations are required before a successful conclusion of each test.

IT Infrastructure
As part of Work Stream 2 scope, the IT infrastructure was procured, installed, validated against architecture design and
made available for deployment of the SOCS solution. In particular, in this reporting period the following environments
were implemented:

FOSS Test environment – comprising of an application server and a database server; on these servers Oracle
and IBM WebSphere were installed and then connected the application server to a test instance of the IBM
Websphere MQ/IBM Integration Bus. AMT-Sybex then installed the FOSS application and database tier
connecting to a test instance of PI database. Finally, after the all the connectivity checks, the FOSS system
was ready for Site Acceptance Test (SAT) on this environment.

FOSS Production Environment – similar to FOSS Test environment, the production environment comprising of
an application server and database server; fully installed with Oracle and IBM WebSphere and integrated with
the production instance of the IBM Integration Bus. Then AMT-Sybex installed the SAT accepted version of
FOSS solution onto this Production environment and connected the database with Production PI SCADA
database. Finally, after the all the connectivity checks, the FOSS system was ready for System Integration test
on this environment.

BESSM test – this system was set up in Berlin by Younicos which was connected to test BESDM machines
which in turn was connected with a battery simulator. UK Power Networks conducted its Factory Acceptance
Test on this environment. Following the FAT period, this environment was used for testing connectivity with
IBM Integration Bus and the Test RTU.

BESSM Production – as part of the commissioning plan the BESSM and BESDM production infrastructure was
installed and implemented at Leighton Buzzard. This production environment is being used to perform the end
to end System Integration Testing.

ENMAC Pre-Production – an extract of the current ENMAC system was taken from production and restored in
a Pre-Production instance of ENMAC, and then the SNS changes were configured on top. This had to be
aligned with the line drawings defined by the drawing office team to change the EPN diagram to reflect SNS on
the control system. ENMAC Pre-Production was linked to the PI testing database.

RTU Test environment – a test RTU was modelled on the final Production RTU design and configured
accordingly. This was connected up to the Pre-Production ENMAC system, a network simulator and BESSM
test system in Berlin. The test RTU was used to confirm the DNP3 measurements settings between BESSM
and the RTU

RTU Production – as part of the SNS project it was a strategic decision to replace the RTU with a new T5500
RTU, this was installed at Leighton Buzzard during this phase. The SNS configurations were then installed on
top of the existing setup allowing SNS data to be transmitted to control and PI system via production ENMAC.
The SOCS technical solution is split between multiple sites with the principal UK Power Networks sites being the
Leighton Buzzard sub-station, UK Power Networks control centre and the UK Power Networks data centre. There are
external connections from non-UK Power Networks systems being integrated into the design.
The ESS is sited at Leighton Buzzard and has the need for resilient, real-time communication with the storage device.
Therefore, the following communication requirements were delivered in this reporting period:

Communication with storage device at Leighton Buzzard via a fibre broadband connection and backup ADSL
link;

Communication with the on-site RTU at Leighton Buzzard;

Communication with other SOCS components via the UK Power Networks’ ESB;

Provision of remote access for partners/suppliers to provide support.
Page 24 of 54
The communication architecture enables ESS to communicate with different parts of the UK Power Networks’ network
infrastructure: The on-site RTU is on the SCADA VRF (Virtual Routing and Forwarding), whilst the ESB is on the
corporate VRF, and third party support is normally provisioned through VPN tunnels through the corporate VRF. As a
result a number of firewall rules had to be configured across the UK Power Networks’ communication infrastructure.
Key Issues Encountered
A number of issues were encountered during development and test phase of the project. The key ones that had an
impact on the project time lines are listed below:

RTU firmware had to be upgraded to cope with DNP3 protocol
When testing data points between BESSM and RTU it transpired that the firmware version used on RTUs did
not have the DNP3 protocol capabilities contrary to technical documentation. Thus after numerous test and
consultations with General Electric (GE) it was deduced that a latest version of the RTU firmware was required.
This delayed the RTU configuration and testing by approximately four weeks which in turn had an impact on
testing the DNP3 settings defined in BESSM. Additional consultancy was required from GE at an extra spend
of £3,100.

Vodafone & BT data communications issues
There were number of process related issues with getting Vodafone to deliver the VRF connection at Leighton
Buzzard. After a number of site surveys it was deduced that BT Openreach needed to dig the road outside the
UK Power Networks building in Leighton Buzzard. Secondly, the routers and switches installed were
incorrectly configured. This did not have any impact onto the overall project timelines, though it resulted in the
WS lead spending a lot of time chasing the supplier.

Revisited the Energy Cost model for the optimisation algorithms
During the design walk through of the optimisation module, it was agreed with Newcastle University that the
energy calculation can be improved and thus a revised model was designed. This has now been implemented
as part of the optimisation solution. This delayed the delivery of the FOSS phase 2 by approximately eight
weeks form originally planned. There were no addition costs incurred as AMT-Sybex and Newcastle University
absorbed this additional effort in their timetable to accommodate this refinement.
Key Deliverables
During this period the following milestones were achieved:

SNS 1.3 – SNS Testing Strategy

SNS 2.5 – Demand Forecast Error Analysis

SNS 2.10 – SOCS Training

SNS 2.12 – Long Term Electricity Demand Forecast for Energy Storage Scheduling


2.1.5 WS 3 – Storage Value Streams, Services and Modelling
WS 3 predominantly covers the activities relating to the operational phase of the project, including the design and
execution of the range of trials to demonstrate the storage capability across a range of distribution network, ancillary
and wholesale services.
Progress against plan
In this reporting period, the detailed trial designs have been completed and the DNO trials are ready to be initiated as
illustrated in Figure 16.

Figure 16: High Level Deliverables of WS 3 during the Project Lifecycle
Within DNO trials, a number of pre-trial tests will be conducted to validate that the SNS software and hardware solution
is able and ready to deliver the core and long-term trials. It should be noted that numerous tests have been conducted
previously under WS 1 and WS 2 commissioning and testing processes; however these WS 3 pre-trial tests are part of
the whole SNS System Integration Testing, firstly because they require a number of SOCS subsystems and ESS
hardware to be integrated and secondly, because they aim to verify that the anticipated functions of the end to end
SNS solution comply with the requirements to deliver the core trials. Specifically, the pre-trial tests to be conducted are:

Set-point stability and accuracy tests: the aim of these tests is to ensure that the required set-points were
sufficiently realised by the BESSM control system and that network voltage changes does not affect the
realisation of the set-points.

Reserve tests: the aim of these tests is (i) to ensure that the interface with KiWi Power was efficient in
transferring dispatch/deactivation signals for the delivery of reserve services (i.e. Fast Reserve and Short
Term Operating Reserve) following an instruction from National Grid and (ii) to ensure that BESSM
delivers the service within required performance criteria that include defined energy delivery within specific
timelines.

Response tests: the aim of these tests is to ensure that BESSM is able to deliver response services (i.e.
Frequency Control by Demand Management, Static and Dynamic Firm Frequency Response) adhering to
the required technical characteristics (i.e. dispatch power vs grid frequency characteristic) within the
required response time (i.e. 2 seconds).

Peak shaving tests: the aim of these tests is to ensure that BESSM is able to deliver peak shaving using
active and reactive power capabilities of the ESS taking into account various pre-defined parameters (such
as loading limit at the 11kV) and trigger signals from the RTU to flag N-1 conditions.
The above tests are planned to be carried out and their results will be documented in the DNO Trials report which will
be completed in the next reporting period.
Operational and reporting templates for the trial period have been developed. These templates will be used by the SNS
operational team to inform the control room and network operations of the upcoming trials on a weekly basis, but also
aggregate operational and anticipated costing information to assist with reconciliation of the cash flows between UK
Power Networks and the trial partners during the trial period.
Page 26 of 54
Modelling work has been conducted to support the negotiations between UK Power Networks and National Grid for
deciding the pricing for frequency response services provision. Availability and utilisation prices were decided based on
the installed cost of SNS, fixed and variable charges that are anticipated during its operation and an index-linked
component for energy utilisation and these have now been factored into the new business case view as shown in
Section 3.
The metering system that will be used in SNS has been designed and developed with Siemens plc and FAT was
witnessed successfully on 26 June. The metering system was installed, and was commissioned on 15 November. The
contracts required for metering system provision and metering system operation have been finalised and signed.
A spreadsheet-based tool that will serve as a decision making tool for acceptance or rejection of a tolling profile has
been developed. Every Friday, a tolling profile for the following week will be sent by Smartest Energy and the SNS
operational team will use this tool to evaluate whether the proposed profile is technically feasible. This tool requires as
inputs the load forecast for the evaluation week and the active schedule for that week that indicates the services that
have already been booked and their parameters.
A triad avoidance process has been developed. During each triad period (i.e. November to February inclusive each
year), Smartest Energy and KiWi Power will send approximately 25-40 triad warning messages via email to the SNS
operational team highlighting the possibility of a triad on the day of the warning. Triad forecasting has been out of the
scope of the SOCS system and the SNS operational team will consult the triad avoidance process on receipt of a triad
warning message to decide whether amendment in the daily dispatch schedule is required to minimise the potential
costs from importing energy during the triad period.
No issues have been encountered in this area during this reporting period.

2.1.6 WS 4 – Commercial & Regulatory Frameworks
This work-stream is responsible for the commercial and regulatory aspects of the project, including assessment and
validation of specific business models for storage, and identification of key regulatory barriers.
2.1.6.1
Smart Commercial Agreements
The key focus and deliverables from this work-stream during the period has been the completion of a report detailing
Commercial Arrangements for Integrated Use of Flexibility (SDRC 9.3 report, SNS4.6) together with the completion
and signing of agreements with Smartest Energy and Kiwi Power. This together with a confidential report compiling
other relevant evidence, mainly meetings and workshop notes, forms the evidence demonstrating the successful
completion of successful delivery reward criteria 9.3.
During this reporting period, the new Storage ‘Aggregator Services Agreement’, which has been under development
over the course of this year, was completed. The contract allows delivery of the range of ancillary services to be trialled
with Kiwi Power. Kiwi Power has also put in place back-to-back commercial arrangements with National Grid for the
provision of ancillary services using the storage capacity. If storage is to be operated in this multi-purpose way, the
need to access the balancing markets also leads to the requirement for access to the wholesale electricity market to
enable charging and discharging when required.
Page 27 of 54
In the SNS model operated by the project, charging and discharging of the battery is enabled through Smartest Energy,
an energy supplier with whom an Energy Supply and Tolling agreement has also been successfully completed during
the period. This agreement also provides an opportunity for an additional ‘Tolling’ service, which enables the supplier to
take commercial control of the device for a period of time to manage their imbalance risk or arbitrage, in return for a
fixed fee.
Negotiation of these first-of-a-kind contracts has generated a comprehensive understanding of the structure, costs and
benefits of all non-energy related charges and levies that helps to further inform the business case for storage, in
addition to key market-related learning around issues that could pose further barriers to the adoption of energy storage.
SDRC 9.3 demonstrates that these commercial arrangements for the independent service trials and optimised period
of operation have been developed and translated into ‘skeleton’ contract heads of terms, providing the basis of
commercial arrangements that could be tailored for other forms of flexibility and leveraged system wide by other DNOs.
2
The SDRC 9.3 report has been published on the SNS project web page and was submitted to Ofgem before the end
of October.
This learning report describes the implemented smart commercial arrangements for the SNS commercial operating
model, which represent first of a kind contracts for operating storage in this way, and shares them in the form of
‘skeleton’ contract heads of terms. It also identifies new specific learning relating to additional barriers in implementing
such agreements for storage, and in the frameworks for certain industry charges.
The project has been consulted by Ofgem on the legal and regulatory barriers work undertaken, the details of which
were reported in the June 2014 progress report. A presentation was made to the Ofgem WS6 Smart Grid Forum group.
In addition, a response was provided to a letter dated 14 November 2014 from Ofgem seeking a more detailed view on
how storage fits into the current European framework, in particular the ‘third energy package’ (Directive 2009/72/EC).
With regards to the Aggregator Services Agreement, Kiwi Power required suitable back to back arrangements to
support all of the balancing services being provided. Suitable arrangements were in place for all services with the
exception of Firm Frequency Response (FFR). Here, it was necessary for Kiwi Power to negotiate a bespoke back-toback agreement with National Grid. Whilst this negotiation took much longer than was anticipated, it did provide the
project with an opportunity to understand the assessment methodology operated by National Grid, and an opportunity
for National Grid to understand more about the technical capabilities of energy storage. It also identified that there was
a trade-off between the level of pricing and the length of contract that could be achieved. This results from National
Grid factoring their greater uncertainty of requirement into the prices they offer resulting in a short term increase, and is
an additional challenge that new storage developers may face when securing finance for storage projects.

3 Business Case Update
One of the key purposes of the SNS project is to help quantify the general business case for the economic use of grid
scale storage on the distribution network, when leveraged for additional benefits across the full electricity system. Work
associated with developing this business case will come from the specific learning that is gained throughout the life of
the SNS project.
This generic business case will be dependent upon the form of business model which is chosen and the assumptions
that are made regarding all of the current unknowns. This project is looking to identify and quantify many of these
unknowns and apply them to the various different business model structures to help drive forward the adoption of
storage for the benefit of customers and industry. These business model structures were consulted upon in 2013
3
(SNS4.1 – Storage Business Model Structures Consultation) .
For the particular project installation, we are tracking changes to the main drivers of the business case and it is the
project’s intention to use this section to provide an ongoing update to the general economics of the installation as these
drivers evolve and as further learning emerges.
During this period, further refinements to the final costs of the civil build and electrical connection aspects have now fed
into the business case assessment. In addition, the conclusion of the pricing discussions with National Grid have
allowed more accurate pricing to be included for the ancillary services that are to be trialled in the upcoming phases of
the project.
The revised discounted cash flow incorporating all of these changes is shown below.

By way of a reminder, the key assumptions relating to the discounted cash flow analysis are as follows:

All values are Net Present Value, over a 10 year period;

Discount factor used is 7.2%;

‘Installed cost’ represents storage capex and estimated opex over the 10 year period;

Page 30 of 54

‘First of a kind costs’ represent non-core storage installation costs, including other R&D work, and first-of-akind development costs within SNS;

‘Technology cost reduction’ represents the expected price reduction in core storage technology occurring
between the period of the SNS installation, and the point in time when storage would otherwise be installed as
part of a BaU intervention to relieve the network constraint; and

System cost savings represents the wider system efficiencies materialising from reduced curtailment, reduced
greenhouse gas emissions and system balancing and operation savings.
In this reporting period, the overall lifetime installed cost (£11.4m) has become very slightly more favourable, reflecting
more accurate actual costs from the final stages of the site work.
The estimate for future revenues, over the 10 year period, has also increased favourably to £2.6m due to the inclusion
of finalised pricing for FFR. The overall revenues represent a conservative even split between the two key ancillary
services STOR and FFR. Additional services are being trialled as part of the SNS project, but have not been included
here in the interests of maintaining a conservative estimate. As an example, benefits from triad avoidance have not
been factored in, due to the uncertainty in estimating the actual triad periods, however could represent a reasonably
significant additional benefit for commercial storage operators.
As in the previous 6-month report, a basic sensitivity analysis has been performed to indicate an approximate upper
bound of expected revenues for a commercial operator assuming the storage is just optimised towards providing the
higher value service of FFR. The table below shows these results:
Scenario
Future Income Estimate
(10 yr NPV)
Future Net Method Cost
(10 yr NPV)
Even mix of STOR and FFR (as above)
£2.6m
£3.3m
FFR Only
£4.7m
£1.2m
Table 3: Storage revenue sensitivity to operating different services
As shown in the table above, if just the higher value service of FFR is provided, revenues of circa £4.7m may be
possible which would reduce the future net method cost to £1.2m, making the storage solution cost competitive with
the conventional reinforcement (even without the system cost saving aspects included).
This highlights the importance of optimisation in maximising the benefits for storage, and is due to be explored further
within the project using the SOCS platform currently under development.

7 Learning outcomes
7.1 Main Learning Outcomes from the Reporting Period
During this reporting period, SNS has continued to capture specialised learning relating to the construction, installation
and commissioning as well as the regulatory and market aspects of distribution-scale energy storage. The key learning
outcomes from this reporting period are explained below.
A number of key findings have been identified through the installation and commissioning of the storage facility,
development of the SOCS platforms and development of the smart commercial arrangements. These include:
1. Building a large scale ESD in a building presents different challenges to a containerised solution
Important learning has been generated by the project as a result of carrying out the storage installation and
commissioning at this scale in a purpose-built building. Overall system design becomes more important and
additional aspects need greater consideration when installing an ESD into a building rather than in containers.
The reduced distance and screening between plant and equipment presents additional challenges around
electromagnetic interference that may not otherwise be apparent.
Although the root causes of the issues identified are not fully confirmed at time of writing, considerations from
suppliers for a “whole system” design and testing of the systems they supply rather than individual elements
may have gone some way to eliminating the problems seen and the manufacturer has also learnt valuable
lessons from this stage of the project.
2. The application of some standard charges as part of The Electricity Supplier Obligations could lead to
disadvantages for storage operators, and double counting of industry charges
In developing the smart commercial arrangements for the SNS operating model, that have been shared in
SDRC 9.4 (Commercial Arrangements for the integrated use of flexibility), a number of key learning points
have been generated in relation to a number of standard industry charges and their applicability for storage.
Climate Change Levy
In particular, the application of the Climate Change Levy (CCL) to storage, which is an energy tax administered
by HM Revenues & Customs (HMRC) under primary legislation introduced through the Finance Act 2000 leads
to some discrepancies. It is typically levied on energy consumed by industrial and commercial users (but not
domestic consumers). The statutory instrument (SI) that defines the CCL framework defines ‘renewable
sources’ of energy as being ‘sources of energy other than fossil fuel or nuclear fuel and includes waste
provided that it is not waste with an energy content 90 per cent or more of which is derived from fossil fuel’.
Aside from the debate that storage could be considered to be time-shifting energy only, and not a source as
such, this definition could give latitude for storage qualifying as a renewable source of energy, as it is not fossil
fuel or nuclear.
The SI however states that ‘the amount of a supply of renewable source electricity is to be calculated at the
point at which such electricity is first delivered from a generating station to a distribution or transmission system
within the United Kingdom (excluding territorial waters)’. This confirms that a LEC is allocated at the original
point of generation. As export from storage relies first on prior import of energy, this existing generation output
may be from a renewable source, and so a LEC could already have been issued. If this was the case, issuing a
LEC at the point of export from storage would therefore be double-counting.
By default, it may be argued that CCL charges should apply to storage operators, which has the effect of
increasing the import charges for everyday operation. However, from engagement with the HMRC, it was
recognised that the guidance did not deal explicitly with the treatment of energy storage and it was advised that
storage in a battery would not change the fact that it was initially generated from a renewable source.
Therefore HMRC would not see the discharge of electricity from a (lithium-ion) battery storage device as
generation, and therefore it would not be subject to CCL upon discharge. It was possible to reflect this
exemption in the commercial arrangements surrounding the SNS facility, but it is believed the industry would
Page 38 of 54
benefit from formal guidance or amendments to the scheme to ensure consistent application of this exemption
and avoid disadvantages for storage operators.
Contracts for Difference & Feed in Tariff
Similar to the above learning point, the application of renewables subsidy payments including FIT and
Renewable Obligations to storage operators increases import charges and leads to further disadvantages over
conventional generation response providers.
Feed-in tariffs with Contracts for Difference (FIT CfD) will replace the current support mechanism, the
Renewables Obligation (RO), in 2017 after running in parallel from 2013 and will be administered by Ofgem.
The first payments to developers start from April 2015 and a levy will be applied to all suppliers in proportion to
their supply account to pay for it. Imported energy used to charge up storage devices will by default be subject
to this levy.
Similar to the CCL charges above, the subsequent export of energy from storage means that this same energy
will be ‘consumed’ for a second time, meaning that a subsequent customer will be liable for FiT payments on
the same energy. This suggests that suitable exemptions for storage need to be implemented to prevent
double-counting and prevent any disincentives for storage developers.
3. The application of some distribution-related charges do not always reflect the potential value or
capability that the storage system can offer
The project has identified that there may be scope to improve pricing frameworks to better reflect the benefit
that storage could provide to the distribution networks in some circumstances.
A particular example relates to charges to connected customers for reactive power. Reactive power exchange
with the network is currently charged based on the type of asset, i.e. load or generator. The charges are
calculated based on the amount of reactive energy exchanged with the network, but only the amount above
33% of the active power exchange at each half-hourly period, is charged.
Storage systems which include power electronic inverters have the ability to provide four-quadrant operation
(i.e. independent provision of real and reactive power in different directions). However, with the current pricing
structure there is no mechanism to be appropriately compensated (or charged) for combinations of
real/reactive power that are in different directions (e.g. import real power, export reactive power).
As a consequence, there is currently no incentive for any third-party owned/operated storage connected to the
network to provide any reactive power services, that could potentially be utilised for distribution network
support, for example to reduce losses or improve power quality.
4. The firmware of Remote terminal Units (RTUs) should be up to-date prior to testing
The RTU unit is a key device in the overall system that facilities communication between the onsite control
system BESSM, the SCADA network and the FOSS control system. An issue was encountered, as described
further in Section 2.1.4, during the testing of the RTU which manifested as an inability for the BESSM system
to communicate correctly with the RTU.
The cause was the firmware version used on the RTUs which did not have the correct DNP3 protocol
capabilities as described in the latest available technical documentation from GE. Several days of diagnosis
and testing were needed to identify this issue, which could have been avoided if the latest firmware had been
installed at the beginning of the test process.
5. Improved understanding of storage amongst energy suppliers and standardisation of energy supply
contracts is needed to facilitate the adoption of energy storage
A reasonably significant amount of time and effort was required to develop the contract with Smartest Energy
for the energy supply to the storage facility. This was in part due to the first-of-a-kind nature of this contract
Page 39 of 54
between a large-scale DNO-owned storage facility and an energy supplier, but also due to some of the
ambiguities over application of supplemental industry charges, as described in learning points 1 and 2 above.
Contracts more typical of the core business of energy suppliers, for example power purchase agreements with
generators, or standard commercial tariff agreements with demand customers, have been in existence for a
long period of time, and so require relatively little input and development to implement.
In order for this particular commercial model to be a viable and interesting proposition for energy suppliers,
much greater standardisation is needed in these contractual arrangements. Increased awareness of the
benefits and operating characteristics of storage amongst energy suppliers would also benefit the industry in
the same way. The risk otherwise, is that storage developers could find it challenging to put commercial
arrangements in place for efficient access to wholesale markets, and potentially fails to secure the ability to
charge/discharge at economical rates.
6. DNOs may need to contract or develop additional expertise in DC design
It has been identified that DNOs may not have the expertise within their organisation to review and sign-off on
contractor’s design of DC systems. DC system design has some differences from AC system design which
may lie outside the experience of DNO engineers. If this is the case a third party consultancy may be required
or a commercial structure implemented where the contractor self certifies but takes on all the commercial risk.
7.2 Learning, Communications and Dissemination Activities in this Period
As described previously, a comprehensive Knowledge Dissemination Roadmap has been developed in order to
capture all the key learning activities and events. This has continued to evolve and be updated with the project and is

internationally. A number of visits for appropriate stakeholders will be carried out, with the aim to share the learning and
encourage the replication of energy storage projects. The project will continue to disseminate internally, through
ongoing training and briefings to ensure local network and Control staff are confident in the use of the facility, in
addition to beginning the process of informing the Planning departments on the appropriate use of storage in future
network infrastructure development.

9 Risk Management
The SNS project has established a rigorous and proactive risk management process, as described in the SNS Project
Handbook. It allows for the communication and escalation of key risks and issues within the project, it also defines
where decisions will be made and how this will be communicated back to the WS level where the risk or issue has
arisen. Risks are reviewed weekly at WS level and fortnightly at project level by the Project Board. Key project risks are
then escalated to the Project Steering Committee for review and approval of the mitigation on a monthly basis.

Under the EST Agreement with
Smartest there is a risk that UK Power
Networks will have to compensate
Smartest for lost triad benefit costs if
during a week that Tolling has been
chosen and they schedule to export
from the device during what is later
confirmed as a triad period, and UK
Power Networks have chosen to
disrupt their submitted schedule casing
them to lose valuable triad benefit.
ENMAC migration from pre-production
to production has a resource conflict.
Pricing information/back-to-back FFR
arrangements with National Grid are
still outstanding when KiWi service is
due to start on 31/10/14.
ENMAC & RTU development delayed.
Testing of ESS cannot take place
without RTU.
MITIGATING ACTIONS
Risk Closed: Risk was raised with
Connections directorate, and civil works
agreed to be carried out in existing
compound under permitted development.
Monitor risk and initiate mitigating actions if
Stewkley Rd Farm connection is confirmed.
Risk closed: Visualisations were updated
to check visual impact & discussed with
OP&C (UK Power Networks consents
team). Feedback from UK Power Networks’
consents team was that no further
engagement with the council is needed.
Risk closed: Negotiations between KiWi
and National Grid completed.
02/10/14: RTU software upgraded to the
latest version. ENMAC testing started. New
problems have been identified with RTU
calibration.
