Storage Capacity
A report by Kema (now DNV) has estimated
that, based on retrofitting all existing night
storage heaters in the EU-27, SETS can
potentially;
• Introduce 55GW of controllable
capacity by 2050;
• Avoid 7.4TWh/annum of heating
energy
• Avoid 3Million tonnes of CO2
emissions per year.

Potential Value streams
• Multiple power system value streams are of relevance
• Energy arbitrage value, i.e. using energy from generally-cheaper off-peak generation
when compared to generally-costlier peaking plants
• System ancillary services value, i.e. participation in frequency regulation,
primary/replacement reserves provision, and system ramping can increase system
‘flexibility’
• Capacity value, i.e. deferred generation capacity investment costs through demand
shifting away from the hours of the year where the system experiences overall greatest
power demand
• Network investment deferral value, i.e. where costly and environmentally/sociallydifficult upgrades to the transmission and distribution assets can be postponed or
avoided completely

The Quantum Energy System Benefits
NINES – Shetland Islands, Scotland
• Shetland has no connection to the GB grid.
• All energy requirements are provided via
Lerwick Power Station (LPS), Sullom Voe
Terminal (SVT) and Renewables (windfarms).
• Despite massive renewable resources, just 7%
of energy was from renewables
• Objective of NINES is to maximise the amount
or Renewable energy used on the Island’s
electricity grid, whilst reducing reliance on
fossil fuels and reducing carbon emissions
NINES - Project History
• Ofgem funding agreed in Sept. 2011
• The U.Ks first SMART GRID
• Value of the Project is £15.33M
• Timescale – 5 year project ending Dec. 2016
NINES – Developed Architecture
Shetland Daily Demand
Upper limit of system stability
Lower limit of system stability
• The system is full - current demand approaching limits of stability. Extra renewable
generation could exceed system limits
• Load shift using storage to allow new renewables to connect
How did we adapt?
The ANM meets the challenge by providing the ability to
reconsider our approach to dealing with:
•
•
•
•
Alleviation of network constraints
Demand peaks
Demand troughs
The application of limits to the battery and DSM
• So far the system has doubled the connected Renewable generation
capacity (4MW to 8MW). With plans to triple the capacity by the close
of the project.
• Augmenting the stability of the network by utilising the frequency
responsiveness of the Quantum Storage heaters
• Up to 2.4MW of potential storage available
Lessons Learned and Future Steps
• Have been able to put theory into practice
• Lots of learning around consumer interaction with the appliances
• Learning around the operation of batteries for load shifting
• Learning of using thermal storage devices to help balance the grid across
different time horizons
• Project is moving into its knowledge gathering and dissemination phase
(http://www.ninessmartgrid.co.uk/)
• Lerwick Power Station is coming to the end of its operational life.
Tendering currently underway to secure Shetlands future electricity
needs.
BEC - Better Energy Communities
• €1.6million euro project
• Part funded by the Sustainable Energy Authority of Ireland
Objectives :
• Improved the energy efficiency of homes, by retrofitting Quantum SETS
technology in place of traditional night storage heaters and domestic hot water
cylinders. Other measures included the upgrade of building fabric.
• Create a platform to help examine the ability of local small scale storage
technology to create value on the electricity grid system. This is part of the much
larger Horizon 2020 funded RealValue Project (http://www.realvalueproject.com/).
Consortium
Added Value & New Knowledge
• The platform created in BEC project will help us to demonstrate the effect
and quantify the benefits of integrated local small-scale thermal energy
storage on:
Lessons Learned & Next Steps
• Customer recruitment and engagement
• Consumer perception of SETS technology
• Communication challenges
• Integration of systems
• Large scale connection of the appliances to the aggregation platform
• Further deployments of the SETS technology
• Refinement of SETS technology
• Development of commercially viable business models
