Disclaimers IESO This report has been prepared solely for the purpose of assessing whether the connection applicant's proposed connection with the IESO-controlled grid would have an adverse impact on the reliability of the integrated power system and whether the IESO should issue a notice of approval or disapproval of the proposed connection under Chapter 4, section 6 of the Market Rules. Approval of the proposed connection is based on information provided to the IESO by the connection applicant and the transmitter(s) at the time the assessment was carried out. The IESO assumes no responsibility for the accuracy or completeness of such information, including the results of studies carried out by the transmitter(s) at the request of the IESO. Furthermore, the connection approval is subject to further consideration due to changes to this information, or to additional information that may become available after the approval has been granted. Approval of the proposed connection means that there are no significant reliability issues or concerns that would prevent connection of the proposed facility to the IESO-controlled grid. However, connection approval does not ensure that a project will meet all connection requirements. In addition, further issues or concerns may be identified by the transmitter(s) during the detailed design phase that may require changes to equipment characteristics and/or configuration to ensure compliance with physical or equipment limitations, or with the Transmission System Code, before connection can be made. This report has not been prepared for any other purpose and should not be used or relied upon by any person for another purpose. This report has been prepared solely for use by the connection applicant and the IESO in accordance with Chapter 4, section 6 of the Market Rules. The IESO assumes no responsibility to any third party for any use, which it makes of this report. Any liability which the IESO may have to the connection applicant in respect of this report is governed by Chapter 1, section 13 of the Market Rules. In the event that the IESO provides a draft of this report to the connection applicant, you must be aware that the IESO may revise drafts of this report at any time in its sole discretion without notice to you. Although the IESO will use its best efforts to advise you of any such changes, it is the responsibility of the connection applicant to ensure that it is using the most recent version of this report. HYDRO ONE Special Notes and Limitations of Study Results The results reported in this study are based on the information available to Hydro One, at the time of the study, suitable for a System Impact Assessment of a new generation or load connection proposal. The short circuit and thermal loading levels have been computed based on the information available at the time of the study. These levels may be higher or lower if the connection information changes as a result of, but not limited to, subsequent design modifications or when more accurate test measurement data is available. System Impact Assessment Report Disclaimers This study does not assess the short circuit or thermal loading impact of the proposed connection on facilities owned by other load and generation (including OPG) customers. In this study, short circuit adequacy is assessed only for Hydro One breakers and does not include other Hydro One facilities. The short circuit results are only for the purpose of assessing the capabilities of existing Hydro One breakers and identifying upgrades required to incorporate the proposed connection. These results should not be used in the design and engineering of new facilities for the proposed connection. The necessary data will be provided by Hydro One and discussed with the connection proponent upon request. The ampacity ratings of Hydro One facilities are established based on assumptions used in Hydro One for power system planning studies. The actual ampacity ratings during operations may be determined in real-time and are based on actual system conditions, including ambient temperature, wind speed and facility loading, and may be higher or lower than those stated in this study. The additional facilities or upgrades which are required to incorporate the proposed connection have been identified to the extent permitted by a System Impact Assessment under the current IESO Connection Assessment and Approval process. Additional facility studies may be necessary to confirm constructability and the time required for construction. Further studies at more advanced stages of the project development may identify additional facilities that need to be provided or that require upgrading.

The installation of the new generator will add approximately 10 MW to 15MW of generation alongside the existing 41.9 MVA turbogenerator (G1). Currently, the facility consumes on average about 7 MW of load. After the installation of the new generator, Domtar expects the facility to be capable of exporting a maximum of 2.5 MW to the IESO-controlled grid through the overhead transmission line D5D. The proposed in service date for the generation unit is December 2011. This assessment examined the impact of injecting 2.5 MW of generation from the Domtar Dryden facility into the provincial grid via the 115 kV circuit D5D on the reliability of the IESO-controlled grid. Findings The following conclusions are achieved based on this assessment: (1) The proposed connection arrangement and equipment for the 15.9 MVA generator at Domtar Dryden does not have a material adverse impact on the reliability of the IESO-controlled grid (2) The system fault levels after the incorporation of the 15.9 MVA generator at Domtar Dryden will not exceed the interrupting capabilities of the existing breakers on the IESO-controlled grid near this facility. (3) Pre-Contingency Thermal Analysis: No pre-contingency thermal overloads were identified under high transfer east or high transfer west conditions. (4) Post-Contingency Thermal Analysis under High Transfer East Conditions: The potential for congestion exists on the 115 kV circuits M2D and B6M for the loss of 230 kV circuits D26A and A21L, respectively under pre-Domtar Dryden expansion conditions. The connection of 15.9MVA generator at Domtar Dryden may slightly increase the power flow on the circuits by up to 4% for existing conditions. (5) Post-Contingency Thermal Analysis under High Transfer West Conditions: The potential for congestion exists on the 115 kV circuit K3D for the loss of the 230 kV circuit K23D under preDomtar Dryden expansion conditions. The connection of the 15.9 MVA generator at Domtar Dryden may slightly increase the power flow on this circuit by up to 0.4% from existing conditions. (6) The connection applicant will be connecting in the Northwest Ontario, an area of the power system that may experience congestion. At times, the connection applicant may be required to curtail the level of generation within its system for reliability purposes. (6) The maximum voltage declines were found to be within 10% pre and post-ULTC action limit. (7) Based on the information provided by the applicant, the governor for the new 15.9 MVA generator will result in a droop of about 5%, which is within the required range of 3% to 7%. CAA ID 2010-420 1 August 16, 2011 System Impact Assessment Report Executive Summary (8) The incorporation of the Domtar facility does not cause any material adverse impact on the transient performance of the IESO-controlled grid. (9) The relay margins calculated under post-contingency conditions for various monitored circuits are sufficient with the new generator at Domtar Dryden in-service. (10) The Protection Impact Assessment conducted by the transmitter identified the following: • Existing protection hardware, protection settings and telecommunication links are adequate. • Connection applicant must provide redundant distance protection scheme on D5D and must be able to reliably disconnect their equipment for a fault on D5D or M2D (when supplied by M2D). (11) The Market Rules governing the connection of renewable generation facilities in Ontario are currently being reviewed through the SE-91 stakeholder initiative and, therefore, new connection requirements (in addition to those outlined in the SIA), may be imposed in the future. The applicant is encouraged to follow developments and updates through the following link: http://www.ieso.ca/imoweb/consult/consult_se91.asp IESO’s Requirements for Connection Transmitter Requirements The following requirements are applicable to Hydro One for the incorporation of the 15.9 MVA Domtar Dryden backpressure topping turbine generator: (1) The transmitter is required to review the relay settings of the 115 kV circuit D5D at Dryden TS and any other circuits affected by the new generator. Modifications to protection relays after this SIA is finalized must be submitted to IESO as soon as possible or at least six (6) months before any modifications are to be implemented on the existing protection systems. Mitigation solutions to address modifications resulting in adverse impact on reliability must be jointly developed with the applicant. Connection Applicant Requirements Specific Requirements: The following specific requirements are applicable to the applicant for the incorporation of the 15.9 MVA Domtar Dryden backpressure topping turbine generator. Specific requirements pertain to the level of reactive compensation needed, operation restrictions, Special Protection Systems, upgrading of equipment and any project specific items not covered in the general requirements: (1) A directly connected generating facility must have the capability to inject or withdraw reactive power continuously at its connection point. The amount of reactive power required is up to 33% of its rated active power at all levels of active power output except where a lesser continually available capability is permitted by the IESO. Since the facility will inject a maximum active power of 2.5MW, the facility would be required to have the capability provide ±0.825 Mvar of dynamic reactive power. CAA ID 2010-420 2 August 16, 2011 System Impact Assessment Report Executive Summary The IESO has determined that, for the time being, the facility is not required to have the capability to provide dynamic reactive power at the point of connection nor control the voltage at the point of connection as specified in Appendix 4.2 of the Market Rules. The connection applicant, however, will need to ensure that, with the incorporation of the new generation unit, the facility is capable of operating at a power factor range of 0.9 lagging to 0.9 leading as measured at the defined meter point. The IESO will direct the reactive output of the facility to a specific value within its capability during operations as system conditions require. It should be noted that, should system conditions in the area change in the future, the IESO may require that the facility provide dynamic reactive power and control the voltage at the point of connection. (2) Under normal operating conditions, the connection applicant must ensure that the facility does not inject more than 2.5 MW into the grid. The connection applicant must contact the IESO for a new System Impact Assessment should an injection greater than 2.5 MW be required in the future. Should abnormal operating conditions arise in which the injection could momentarily exceed 2.5 MW, the connection applicant must immediately return the injection to 2.5 MW or less within 15 minutes of occurrence. If future IESO monitoring show injections exceeding 2.5 MW for durations greater than 15 minutes, additional studies, requirements and/or possible disconnection of the facility may result. General Requirements: The connection applicant shall satisfy the applicable requirements and standards specified in the Market Rules, Market Manuals and the Transmission System Code. The following requirements summarize some of the general requirements that are applicable to the proposed project, and presented in section 2 of this report. (1) The connection applicant shall ensure that the facility has the capability to operate continuously between 59.4Hz and 60.6Hz and for a limited period of time in the region above straight lines on a log-linear scale defined by the points (0.0s, 57.0Hz), (3.3s, 57.0Hz), and (300s, 59.0Hz). The facility shall regulate speed with an average droop based on maximum active power adjustable between 3% and 7% and set at 4%. Regulation deadband shall not be wider than ± 0.06%. Speed shall be controlled in a stable fashion in both interconnected and island operation. A sustained 10% change of rated active power after 10 s in response to a constant rate of change of speed of 0.1%/s during interconnected operation shall be achievable. (2) The connection applicant shall ensure that the facility has the capability to: • Supply continuously all levels of active power output for 5% deviations in terminal voltage. • Output reactive power as indicated in (1) under the Specific Connection Applicant requirements above. (3) The generation facility shall have the capability to ride through routine switching events and design criteria contingencies assuming standard fault detection, auxiliary relaying, communication, and rated breaker interrupting times unless disconnected by configuration. (4) The connection applicant shall ensure that the 115 kV equipment is capable of continuously operating between 113 kV and 132 kV. Protective relaying must be set to ensure that transmission equipment remains in-service for voltages between 94% of the minimum CAA ID 2010-420 3 August 16, 2011 System Impact Assessment Report Executive Summary continuous value and 105% of the maximum continuous value specified in Appendix 4.1of the Market Rules. (5) The connection applicant shall ensure that the connection equipment is designed to be fully operational in all reasonably foreseeable ambient temperature conditions. The connection equipment must also be designed so that the adverse effects of its failure on the IESO-controlled grid are mitigated. This includes ensuring that all circuit breakers fail in the open position. (6) The connection applicant shall ensure that the new equipment at the facility be designed to sustain the fault levels in the area. If any future system enhancement results in an increased fault level higher than the equipment’s capability, the connection applicant is required to replace the equipment at its own expense with higher rated equipment capable of sustaining the increased fault level, up to maximum fault level specified in Appendix 2 of the Transmission System Code. Fault interrupting devices must be able to interrupt fault currents at the maximum continuous voltage of 132 kV. (7) The connection applicant shall ensure that the new protection systems at the facility are designed to satisfy all the requirements of the Transmission System Code and any additional requirements identified by the transmitter. The connection applicant shall have adequate provision in the design of protections and controls at the facility to allow for future installation of Special Protection Scheme (SPS) equipment. The protection systems within the generation facility must only trip the appropriate equipment required to isolate the fault. The autoreclosure of the high voltage breakers at the connection point must be blocked. Upon its opening for a contingency, the high voltage breaker must be closed only after the IESO approval is granted. Any modifications made to protection relays by the transmitter after this SIA is finalized must be submitted to the IESO as soon as possible or at least six (6) months before any modifications are to be implemented on the existing protection systems. (8) The connection applicant shall ensure that the telemetry requirements are satisfied as per the applicable Market Rules requirements. The determination of telemetry quantities and telemetry testing will be conducted during the IESO Facility Registration/Market Entry process. (9) If revenue metering equipment is being installed as part of this project, the connection applicant should be aware that revenue metering installations must comply with Chapter 6 of the IESO Market Rules. For more details the connection applicant is encouraged to seek advice from their Metering Service Provider (MSP) or from the IESO metering group. (10) The proposed facility must be compliant with applicable reliability standards set by the North American Electric Reliability Corporation (NERC) and the North East Power Coordinating Council (NPCC) that are in effect in Ontario as mapped in the following link: http://www.ieso.ca/imoweb/ircp/orcp.asp (11) Domtar Dryden is currently a restoration participant. The connection applicant is required to update its restoration participant attachment to include details regarding its proposed project. For more details please refer to the Market Manual 7.8. Details regarding restoration CAA ID 2010-420 4 August 16, 2011 System Impact Assessment Report Executive Summary participant requirements will be finalized at the Facility Registration/Market Entry Stage. (12) The connection applicant must complete the IESO Facility Registration/Market Entry process in a timely manner before IESO final approval for connection is granted. Models and data, including any controls that would be operational, must be provided to the IESO at least seven months before energization to the IESO-controlled grid. This includes both PSS/E and DSA software compatible mathematical models representing the new equipment for further IESO, NPCC and NERC analytical studies. The connection applicant must also provide evidence to the IESO confirming that the equipment installed meets the Market Rules requirements and matches or exceeds the performance predicted in this assessment. This evidence shall be either type tests done in a controlled environment or commissioning tests done on-site. The evidence must be supplied to the IESO within 30 days after completion of commissioning tests. If the submitted models and data differ materially from the ones used in this assessment, then further analysis of the project will need to be done by the IESO. Notification of Conditional Approval The proposed connection of the 15.9 MVA generator within the Domtar Dryden facility resulting in a maximum net injection of 2.5 MW to the IESO controlled grid is expected to have no material adverse impact on the reliability of the integrated power system, subject to the requirements specified in this report. It is recommended that a Notification of Conditional Approval for the addition of the 15.9 MVA generation unit be issued to Domtar Pulp and Paper Products Inc., subject to the implementation of the requirements outlined in this report. CAA ID 2010-420 5 August 16, 2011 System Impact Assessment Report 1. Project Description Project Description The Domtar Dryden facility is a grid connected load facility that produces market pulp and has a maximum load of approximately 30 MW. Currently, the facility has an existing 41.9 MVA steam turbine generator (G1). In 2004, a new black liquor recovery boiler was installed at the plant. This boiler is capable of generating steam at a pressure higher than a level that can be used by existing steam turbine generator. In order for the pressure to be suitable for the existing steam turbine generator, the recovery boiler is operated at a reduced energy level and the steam pressure is reduced by a steam conditioning valve. Due to this constraint, the existing generator can only produce a maximum output of 22.4 MW. Currently, the facility imports about 0 to 7 MW from IESO controlled grid with more imports during the summer months than the winter months. Domtar Pulp and Paper Products Inc. is proposing to install a new 15.9 MVA backpressure topping turbine generator (G2) at the 13.2 kV Bus #3 of the Domtar Dryden facility. The new turbine will operate with inlet steam conditions of the existing black liquor recovery boiler and exhaust to the steam system supplying the existing 41.9MVA turbogenerator. After installing the new generator, Domtar expects that a maximum of 2.5MW will be constantly exported to the IESO-controlled grid through the overhead transmission line D5D. The Domtar Dryden facility is connected to Hydro One's transmission line D5D through three 115/13.2 kV step down transformers T1, T2 and T3, with the transformer T3 normally out of service. The existing 41.9MVA generator will be set to a power factor of 0.9 to 0.95 lagging at the generator terminal. The new 15.9 MVA generator will be set to control the power factor at the facility defined meter point at a value between 0.9 lagging and 0.9 leading. The proposed in service date for the generation unit is December, 2011. – End of Section – CAA ID 2010-420 6 August 16, 2011 System Impact Assessment Report 2. IESO’s General Requirements IESO’s General Requirements The connection applicant shall satisfy the requirements and standards specified in the Market Rules, Market Manuals and the Transmission System Code. The following sections highlight some of the general requirements that are applicable to the proposed project. 2.1 Frequency/Speed Requirements As per Appendix 4.2 of the Market Rules, the connection applicant shall ensure that the generation facility has the capability to operate continuously between 59.4 Hz and 60.6 Hz and for a limited period of time in the region above straight lines on a log-linear scale defined by the points (0.0 s, 57.0 Hz), (3.3 s, 57.0 Hz), and (300 s, 59.0 Hz), as shown in the following figure. The facility has to have the capability to regulate speed with an average droop based on maximum active power adjustable between 3% and 7% and set at 4% unless otherwise specified by the IESO. Regulation deadband shall not be wider than ± 0.06%. Speed shall be controlled in a stable fashion in both interconnected and island operation. A sustained 10% change of rated active power after 10 s in response to a constant rate of change of speed of 0.1%/s during interconnected operation shall be achievable. Due consideration will be given to inherent limitations such as mill points and gate limits when evaluating active power changes. Control systems that inhibit governor response shall not be enabled without IESO approval. 2.2 Reactive Power/Voltage Regulation Requirements The generation facilities directly connected to the IESO-controlled grid should be capable to: • Supply continuously all levels of active power output for 5% deviations in terminal voltage. Rated active power is the smaller output at either rated ambient conditions (e.g. temperature, head, wind CAA ID 2010-420 7 August 16, 2011 System Impact Assessment Report IESO’s General Requirements speed, solar radiation) or 90% of rated apparent power. To satisfy steady-state reactive power requirements, active power reductions to rated active power are permitted. • Inject or withdraw reactive power continuously (i.e. dynamically) at a connection point up to 33% of its rated active power at all levels of active power output except where a lesser continually available capability is permitted by the IESO. If necessary, shunt capacitors must be installed to offset the reactive power losses within the facility in excess of the maximum allowable losses. If generators do not have dynamic reactive power capabilities, dynamic reactive compensation devices must be installed to make up the deficient reactive power. • Regulate automatically voltage within ±0.5% of any set point within ±5% of rated voltage at a point whose impedance (based on rated apparent power and rated voltage) is not more than 13% from the highest voltage terminal. If the AVR target voltage is a function of reactive output, the slope ∆V/∆Qmax shall be adjustable to 0.5%. The equivalent time constants shall not be longer than 20 ms for voltage sensing and 10 ms for the forward path to the exciter output. AVR reference compensation shall be adjustable to within 10% of the unsaturated direct axis reactance on the unit side from a bus common to multiple units. Please refer to Section 5.5 of this report for specific reactive power and voltage regulation requirements for Domtar Dryden facility. 2.3 Voltage Ride Through Requirements The generation facility shall have the capability to ride through routine switching events and design criteria contingencies assuming standard fault detection, auxiliary relaying, communication, and rated breaker interrupting times unless disconnected by configuration. 2.4 Voltage Requirements Appendix 4.1 of the Market Rules states that under normal operating conditions, the voltages in the 115 kV system in northern Ontario are maintained within the range of 113 kV to 132 kV. Thus, the IESO requires that the 115 kV equipment in northern Ontario must have a maximum continuous voltage rating of at least 132 kV. Protective relaying must be set to ensure that transmission equipment remains in-service for voltages between 94% of the minimum continuous value and 105% of the maximum continuous value specified in Appendix 4.1of the Market Rules. 2.5 Connection Equipment Design Requirements The connection applicant shall ensure that the connection equipment is designed to be fully operational in all reasonably foreseeable ambient temperature conditions. The connection equipment must also be designed so that the adverse effects of its failure on the IESO-controlled grid are mitigated. This includes ensuring that all circuit breakers fail in the open position. CAA ID 2010-420 8 August 16, 2011 System Impact Assessment Report IESO’s General Requirements 2.6 Fault Level Requirement The Transmission System Code requires the new equipment to be designed to sustain the fault levels in the area where the equipment is installed. Thus, the connection applicant shall ensure that the new equipment at the facility is designed to sustain the fault levels in the area. If any future system enhancement results in an increased fault level higher than the equipment’s capability, the connection applicant is required to replace the equipment at its own expense with higher rated equipment capable of sustaining the increased fault level, up to maximum fault level specified in the Transmission System Code. Appendix 2 of the Transmission System Code establishes the maximum fault levels for the transmission system. For the 115 kV system, the maximum 3 phase and single line to ground symmetrical fault levels are 50 kA. Fault interrupting devices must be able to interrupt fault currents at the maximum continuous voltage of 132 kV. 2.7 Protection System Requirements The connection applicant shall ensure that the protection systems are designed to satisfy all the requirements of the Transmission System Code as specified in Schedules E, F and G of Appendix 1 and any additional requirements identified by the transmitter. New protection systems must be coordinated with the existing protection systems. The connection applicant is required to have adequate provision in the design of protections and controls at the facility to allow for future installation of Special Protection Scheme (SPS) equipment. Should a future SPS be installed to improve the transfer capability in the area or to accommodate transmission reinforcement projects, the facility will be required to participate in the SPS system and to install the necessary protection and control facilities to affect the required actions. The protection systems within the generation facility must only trip the appropriate equipment required to isolate the fault. After the facility begins commercial operation, if an improper trip of the 115 kV circuit D5D occurs due to events within the facility, the facility may be required to be disconnected from the IESO-controlled grid until the problem is resolved. The autoreclosure of the high voltage breakers at the connection point must be blocked. Upon its opening for a contingency, the high voltage breaker must be closed only after the IESO approval is granted. Any modifications made to protection relays by the transmitter after this SIA is finalized must be submitted to the IESO as soon as possible or at least six (6) months before any modifications are to be implemented on the existing protection systems. If those modifications result in adverse impacts, the connection applicant and the transmitter must develop mitigation solutions 2.8 Telemetry Requirements If applicable according to Section 7.3 of Chapter 4 of the Market Rules, the connection applicant shall provide to the IESO the applicable telemetry data listed in Appendix 4.15 of the Market Rules on a continual basis. The data shall be provided in accordance with the performance standards set forth in Appendix 4.19, subject to Section 7.6A of Chapter 4 of the Market Rules. The data is to consist of certain equipment status and operating quantities which will be identified during the IESO Facility CAA ID 2010-420 9 August 16, 2011 System Impact Assessment Report IESO’s General Requirements Registration/Market Entry Process. To provide the required data, the connection applicant must install at this project monitoring equipment that meets the requirements set forth in Appendix 2.2 of Chapter 2 of the Market rules. As part of the IESO Facility Registration/Market Entry process, the connection applicant must also complete end to end testing of all necessary telemetry points with the IESO to ensure that standards are met and that sign conventions are understood. All found anomalies must be corrected before IESO final approval to connect any phase of the project is granted. 2.9 Revenue Metering Requirements If revenue metering equipment is being installed as part of this project, the connection applicant should be aware that revenue metering installations must comply with Chapter 6 of the IESO Market Rules. For more details the connection applicant is encouraged to seek advice from their Metering Service Provider (MSP) or from the IESO metering group. 2.10 Reliability Standards Requirements Prior to connecting to the IESO controlled grid, the proposed facility must be compliant with the applicable reliability standards established by the North American Electric Reliability Corporation (NERC) and reliability criteria established by the Northeast Power Coordinating Council (NPCC) that are in effect in Ontario. A mapping of applicable standards, based on the proponent’s/connection applicant’s market role/OEB license can be found here: http://www.ieso.ca/imoweb/ircp/orcp.asp This mapping is updated periodically after new or revised standards become effective in Ontario. The current versions of these NERC standards and NPCC criteria can be found at the following websites: http://www.nerc.com/page.php?cid=2|20 http://www.npcc.org/documents/regStandards/Directories.aspx The IESO monitors and assesses market participant compliance with a selection of applicable reliability standards each year as part of the Ontario Reliability Compliance Program.

CAA ID 2010-420 10 August 16, 2011 System Impact Assessment Report 2.11 IESO’s General Requirements Restoration Participant Requirements The connection applicant is currently a restoration participant. The connection applicant is required to update its restoration participant attachment to include details regarding its proposed project. For more details please refer to the Market Manual 7.8. Details regarding restoration participant requirements will be finalized at the Facility Registration/Market Entry Stage. 2.12 Facility Registration/Market Entry Requirements The connection applicant must complete the IESO Facility Registration/Market Entry process in a timely manner before IESO final approval for connection is granted. Models and data, including any controls that would be operational, must be provided to the IESO. This includes both PSS/E and DSA software compatible mathematical models representing the new equipment for further IESO, NPCC and NERC analytical studies. The connection applicant may need to contact the software manufacturers directly, in order to have the models included in their packages. This information should be submitted at least seven months before energization to the IESO-controlled grid, to allow the IESO to incorporate this project into IESO work systems and to perform any additional reliability studies. As part of the IESO Facility Registration/Market Entry process, the connection applicant must provide evidence to the IESO confirming that the equipment installed meets the Market Rules requirements and matches or exceeds the performance predicted in this assessment. This evidence shall be either type tests done in a controlled environment or commissioning tests done on-site. In either case, the testing must be done not only in accordance with widely recognized standards, but also to the satisfaction of the IESO. Until this evidence is provided and found acceptable to the IESO, the Facility Registration/Market Entry process will not be considered complete and the connection applicant must accept any restrictions the IESO may impose upon this project’s participation in the IESO-administered markets or connection to the IESO-controlled grid. The evidence must be supplied to the IESO within 30 days after completion of commissioning tests. Failure to provide evidence may result in disconnection from the IESO-controlled grid. If the submitted models and data differ materially from the ones used in this assessment, then further analysis of the project will need to be done by the IESO. – End of Section – CAA ID 2010-420 11 August 16, 2011 System Impact Assessment Report 3.

System Impact Studies System Impact Studies This connection assessment was carried out to identify the effect of the proposed facility on thermal loading of transmission interfaces in the vicinity, the system voltages for pre/post contingencies, the ability of the facility to control voltage and the transient performance of the system. 5.1 Study Assumptions The summer 2010 base case was used as the starting point for this assessment. The following general assumptions were considered for setting up the base case: • The total load and generation (including the new generator) at the Domtar Dryden facility were adjusted to reflect the case of maximum power injection into the IESO-controlled grid (2.5MW and 1.2MVAr). • Thunder Bay G2 and G3 units were assumed out of service while Atikokan G1 was assumed inservice. • The local generation in the vicinity of the Domtar Dryden facility was dispatched at the high generation conditions to stress the basecase. • The following projects were included in the basecase: o Fort Frances Capacitor (CAA 2005-195) o Longlac Refurbishment (CAA 2007-EX360) o Dryden Capacitor (CAA 2008-352) o Greenwich Wind Farm (CAA 2008-337) o Kenora Power/Angle Relay Deregistration (CAA 2009-EX448) o Trout Lake River Generation Facility (CAA 2010-390) • Loads were represented by constant MVA loads for thermal and voltage analysis and as voltage dependent loads with P being modeled as 50% constant current and 50% constant impedance (P α V1.5) and Q being modeled as 100% constant impedance (Q α V2) for transient and relay margin analysis. 5.2 Study Scenarios To assess the impacts of the proposed project at Dryden, the following three scenarios were considered for the thermal and voltage assessments: Scenario I (S1) The first scenario reflected high load and high transfers east conditions where the transfers across the main interfaces in the Northwest zone were flowing from the west to the east. The Transfer East of Mackenzie interface for this scenario is 425 MW, which is the limit for when the Ontario Manitoba Transfer East flows are about 300 MW under all elements in-service. The Northwest zone demand was scaled to 410 MW to reflect the extreme weather summer coincident peak forecast for 2012. The Domtar Dryden facility was assumed to be injecting 2.5 MW and 1.21 Mvar (0.9 power factor) at the point of connection. CAA ID 2010-420 21 August 16, 2011 System Impact Assessment Report System Impact Studies Scenario II (S2) The second scenario considered high load and high transfers west conditions where the transfers across the main interfaces in the Northwest zone were flowing from the east to the west. The Transfer West of Mackenzie for this scenario is 346 MW which is approximately the limit under high Flow West conditions for all elements in-service. The Northwest zone demand was scaled to 410 MW to reflect the extreme weather summer coincident peak forecast for 2012. The Domtar Dryden facility was assumed to be injecting 2.5 MW and 1.21 Mvar (0.9 power factor) at the point of connection. Scenario III (S3) The third scenario considered light load and light transfers conditions where the transfers across the main interfaces in the Northwest zone were low and there was approximately no power exchange with Manitoba or Minnesota. In this scenario the Northwest zone demand was scaled to 340 MW to reflect the light load conditions. The Domtar Dryden facility was assumed to be injecting 2.5 MW and 1.21 Mvar (0.9 power factor) at the point of connection. The power flows and voltages for the three scenarios are summarized in the table below: Table 4: Summary of Voltage and Thermal Study Scenarios Scenarios S1 S2 S3 Interface Flows (positive indicates flow is in the defined interface direction) TEK- Transfer East of Kenora 317.3 MW -326.9 MW -15.3 MW TWM - Transfer West of MacKenzie -375.1 MW 346.0 MW 22.7 MW TEM - Transfer East of MacKenzie 425.5 MW -304.6 MW 38.6 MW EWTE - East West Transfer East 325.0 MW -344.9 MW -15.0 MW OMTE - Ontario Manitoba Transfer East 292.2 MW -297.8 MW -0.0 MW 25 MW 5.2 MW -2.5 MW MPFN - Minnesota Power Flow North Line Flows (positive indicates flow is out of the station) D26A at Dryden TS 172.6 MW -125 MW 0.6MW K23D at Dryden TS -128.8 MW 177.4MW 19.1 MW E4D at Dryden TS -75.9MW -75.5 MW -46.0MW M2D at Dryden TS 49.8 MW -30.6 MW 1.7 MW K3D at Dryden TS -19.0 MW 41.7 MW 9.7 MW Dryden 115kV bus 123.3 kV 121.9 kV 123.9 kV Dryden 230kV bus 241.7 kV 239.0 kV 247.3 kV MacKenzie 230kV bus 245.2 kV 244.1 kV 246.1 kV Fort Francis 230kV bus 244.2kV 242.9kV 247.2 kV Rabbit Lake 115kV bus 123.8 kV 122.6 kV 123.2 kV Ear Falls GS 19 MW 19 MW 16 MW Lac Seul GS 12 MW 12 MW 8 MW Manitou Falls GS 72 MW 72 MW 66 MW Trout Lake GS 3.8 MW 3.8 MW 0 MW Bus Voltages Ear Falls Area Generation CAA ID 2010-420 22 August 16, 2011 System Impact Assessment Report System Impact Studies The following are the list of thermal and voltage assessment contingencies studied for each scenario: Table 5: Summary of Studied Contingencies for Thermal and Voltage Assessments Scenario Scenario I Contingencies for Thermal Assessment Contingencies for Voltage Assessment Loss of Dryden T22 Loss of MacKenzie T3 Loss of MacKenzie T3 Loss of the 230kV circuit D26A Loss of the 230kV circuit D26A Loss of the 230kV circuit F25A Loss of the 230kV circuit A21L Loss of the 230kV circuit A21L Loss of the 230kV circuit F25A Loss of the 115kV circuit M2D Loss of 115kV circuit E4D Loss of the 115kV circuit M2D Loss of 115 kV circuit D5D+ Dryden T22 (loss of Domtar facility) Loss of 230kV circuit K3D Loss of 230kV circuit K23D Loss of 115kV circuit K3D Scenario II Loss of 115kV circuit K23D Loss of 115 kV circuit D5D+ Dryden T22 (loss of Domtar facility) Loss of 115kV circuit E4D Scenario III None Loss of 115 kV circuit D5D+ Dryden T22 (loss of Domtar facility) 5.3 Thermal Loading Assessment The purpose of this assessment is to determine the impacts of the proposed project on the thermal loadings of the conductors and auto-transformers in the vicinity of the Domtar Dryden facility. The criteria for the assessment are as follows: a) All lines and equipment loadings shall be within their continuous ratings with all elements in service and within their long-term emergency (LTE) ratings with any one element out of service. b) Immediately following contingencies, lines may be loaded up to their short-term emergency (STE) ratings where control actions such as re-dispatch, switching, etc. are available to reduce the loading to the long-term emergency ratings. For overhead conductors, the continuous ratings are calculated at the lowest of the sag temperature or 93oC operating temperature at 30oC ambient temperature and 4 km/h wind speed. The LTE ratings are calculated at the lowest of the sag temperature and 127oC operating temperature at 30oC ambient temperature and 4 km/h wind speed. The 15-min STE ratings are calculated at the sag temperature of the conductor at 30oC ambient temperature and 4 km/h wind speed for a pre-load equal to the continuous ratings. The percentage loading of the equipment is calculated as follows: CAA ID 2010-420 23 August 16, 2011 System Impact Assessment Report System Impact Studies % 100 The thermal planning ratings used for existing transmission elements were obtained from Hydro One and are presented in Appendix B. The results for the thermal loading assessment for the studied scenarios are presented in the tables of Appendix C where the cells have been shaded to indicate marginally acceptable thermal loadings or thermal overloading. The results in Table C5 show that under high transfers east (Scenario I), the loss of the 230kV circuit D26A following a contingency may overload the 115kV circuit M2D between Dryden TS and Ignace Junction beyond the 15-min STE rating (LTE and 15-min ratings are equal for these sections). To determine whether this overload is an existing problem, a sensitivity test was performed for which the net import from Domtar Dryden is 7 MW – the current typical operating point of the facility under summer conditions. Results show that these overloads still exist and therefore represent an existing issue. For the same scenario, Table C7 shows that the loss of the 230kV circuit A21L following a contingency may overload the 115kV circuit B6M between Birch TS and Murillo Junction beyond the 15-min STE rating. To determine whether these overloads are an existing problem, a sensitivity test was performed for which the net import from the Domtar Dryden is 7 MW. Results show that these overloads would still exist and therefore represent an existing issue. Under high transfers west (Scenario II), the results in Table C13 show that the 115kV circuit K3D sections from Dryden to Rabbit Lake are overloaded beyond its 15-min STE rating (LTE and 15-min ratings are equal) due to the loss of the 230kV circuit K23D following a contingency. To determine whether these overloads are existing problem, a sensitivity test was performed for which the net import from the Domtar Dryden is 7 MW. Results show that these overloads would still exist and therefore represent an existing issue. Based on these findings, the connection applicant should be aware that under certain system conditions, the power output from the Domtar Dryden facility might be curtailed to help alleviate the overloading problems in the area. 5.4 System Voltage Assessment The IESO’s voltage assessment criteria require the pre-contingency voltages in northern Ontario to be within 113 kV to 132 kV for 115 kV buses, 220 kV to 250 kV for 230 kV buses. The criteria also require the post-contingency voltage to be within 108 kV to 132 kV for 115 kV buses, 207 kV to 250 kV for 230 kV buses. In addition, the criteria require that the post-contingency voltage changes should remain within the following limits: • Percentage change in voltage before the tap changer action should not be more than 10%. • Percentage change in voltage after the tap changer action should not be more than 10% at the 115 kV and 230 kV buses. The percentage change in voltage is calculated as follows: CAA ID 2010-420 24 August 16, 2011 System Impact Assessment Report % System Impact Studies !" # $ !" 100 !" The results for the system voltage assessment are presented in the tables of Appendix D. Results show that the voltage levels and the percentage change in voltages at the monitored buses are within the acceptable ranges for all studied scenarios. The largest percentage change in the voltage, 7.4%, is observed under high transfers east (Scenario I) at Dryden 230kV due to the loss of F25A following a contingency. 5.5 Reactive Power Assessment Currently, the Domtar Dryden facility is classified as a load facility that is directly connected to the IESO-controlled grid. The IESO requires that load facilities should have the capability to operate at a power factor between 0.9 lagging and 0.9 leading. After the installation of the new 15.9 MVA generation unit, the facility will inject active power into the grid, and thus, becomes a generation facility that is directly connected to the IESO-controlled grid. A directly connected facility must have the capability to inject and withdraw reactive power continuously at its connection point. The amount of reactive capability required is up to 33% of its rated active power at all levels of active power output except where a lesser continually available capability is permitted by the IESO. Since the facility will inject a maximum active power of 2.5MW, therefore, the facility will be required to provide ±0.825 Mvar of dynamic reactive power. The results of the System Voltage Assessment show that the proposed project has no negative impacts on the voltages in the area for any of the studied conditions. Moreover, the expected contribution of the facility to the reactive power support needed in the area is not significant. Thus, the IESO does not require the facility to provide the dynamic reactive power or to be in voltage control mode for the time being. However, if the system conditions in the area change in the future, the IESO may require that the Domtar Dryden facility provides the required dynamic reactive power and control the voltage at the point of connection as specified in Appendix 4.2 of the Market Rules. For the time being, the connection applicant has to ensure that the Domtar Dryden facility has the capability to operate at a power factor within the range 0.9 lagging to 0.9 leading as measured at the defined meter point after the installation of the new generation unit. Furthermore, the IESO will direct the reactive power of the facility to a specific value within its capability during operations as system conditions require. 5.6 Governor Response Assessment Appendix 4.2 of the Market Rules requires that the generation units that are larger than 10 MW should regulate speed with an average droop based on maximum active power adjustable between 3% and 7% and set at 4% unless otherwise specified by the IESO. The connection applicant has indicated that the governor for the new generation unit is a 1981 IEEE type 1 turbine-governor with the model parameters displayed in Section 3.0 of this report. CAA ID 2010-420 25 August 16, 2011 System Impact Assessment Report System Impact Studies To test the performance of the governor model in PSS/E, the unit was assumed to be loaded at 50% of its rated output and a 1% step change in the loading of the unit was applied. The governor response is shown in Figure 15, where the droop in percent was calculated as follows: %& '( )* # ' )* #4.47993 102 100 100 #4.6% +,( )* # +, )* 0.50975 # 0.5 Figure 15: Governor Response, K=20 The governor response shows a droop of about 5%, which is within the required range of 3% to 7%. 5.7 Protection Impact Assessment A Protection Impact Assessment (PIA) was completed by Hydro One to examine the impact of the new generation unit on the existing transmission system protections. The existing protections for D5D at Dryden TS were described in the PIA report and the proposed protection settings were analyzed based on preliminary fault calculation. Finally, the proposed protection solutions and requirements were presented. A copy of the Protection Impact Assessment can be found in Appendix G of this report. The PIA report concluded that the present protections on D5D can accommodate the increase in generation at the Domtar Dryden facility and will continue to function with the existing scheme for the Dryden TS terminal. Also, the existing settings can cover the new scenario without requiring any CAA ID 2010-420 26 August 16, 2011 System Impact Assessment Report System Impact Studies change and the existing telecommunication links can be retained to maintain the existing remote trip scheme. The report required the connection applicant to provide redundant distance protection scheme to cover faults on D5D (and on the alternate supply M2D when supplied by M2D). The report also required the connection applicant to reliably disconnect their equipment for a fault on D5D (or M2D), even in case that a single contingency failure occurs in their P&C systems. 5.8 Short Circuit Assessment Fault level studies were completed by Hydro One to examine the effects of the new Domtar Dryden 15.9 MVA generator on fault levels at existing facilities in the area.

Fault levels increase slightly when all the proposed generators are in service with the highest increase at Domtar Dryden of 0.303 kA (asymmetrical current) for a 3 phase fault. Therefore, it can be concluded that increases in fault level due to the new Domtar Dryden 15.9 MVA generator will not exceed the interrupting capabilities of the existing breakers on the IESO-controlled grid. CAA ID 2010-420 30 August 16, 2011 System Impact Assessment Report System Impact Studies 5.9 Transient Analysis A transient stability analysis was performed considering faults in the Ear Falls and Dryden area with the new 15.9 MVA generator at Domtar Dryden in-service under a High Transfer East scenario and a High Transfer West scenario. The following LLG contingencies were tested: In both Transfer East and Transfer West cases, Domtar load was assumed to be at 30 MW at 0.92 pf, Domtar G1 was assumed to be operating at 17.5 MW at 0.9 pf and Domtar G2 was assumed to be operating at 15 MW, 3.1 Mvar which would help yield an injection of 2.5 MW, -1.2 Mvar (0.9 pf) at the defined meter point.

CAA ID 2010-420 31 August 16, 2011 System Impact Assessment Report 5.10 System Impact Studies Relay Margin Assessment The IESO requires the relay margin on relays whose operation would not affect the integrity of the IESO-controlled grid be at least 15 percent on all instantaneous relays and zero percent on all timed relays having a time delay setting less than or equal to 0.4 seconds. A relay margin analysis was performed for various contingencies within the vicinity of the Domtar Dryden facility. Plots of the apparent impedance trajectory against the relay characteristics are shown in Appendix F. The nearest point(s) of the trajectory were located and circle(s) depicting the boundary for a 20% relay margin were drawn around the point(s). It is assumed that if the circle does not intercept with any of the relay characteristics, then the relay margin is greater than 20% and the criteria which is stated for a 15% margin is met. The following table summarizes the various contingencies that were simulated, the corresponding relays that were monitored and whether relay margins were sufficient: Table 7: Summary of Relay Margin Results Contingency Voltage Fault Location LLG Fault MVA Fault Clearing Time (ms) Near Remote Flow East Case: TEK = 352.4 MW , TEM=473.1 MW, OMTE =292 MW LLG fault on D26A 230 kV Dryden 365.14 -j3138.90 183 ms Mackenzie LLG fault on A21L 230 kV 581.79 -j4520.86 183 ms 216 ms 216 ms Mackenzie 581.79 -j4520.86 183 ms 216 ms Lakehead 641.47 -j6206.90 183 ms 216 ms Flow West Case: TWM = 350.3 MW, OMTW=300 MW LLG fault on K23D 230 kV Kenora 415.73 -j3036.48 183 ms 216 ms 183 ms 216 ms Dryden CAA ID 2010-420 365.14 -j3138.90 32 Monitored Relays Relay Margin Sufficient M2D @ Moose Lake Yes M2D @ Dryden Yes M2D @ Moose Lake Yes M2D @ Dryden Yes A22L@ Mackenzie A22L@Lakehead B6M @ Birch B6M @ Moose Lake A22L@ Mackenzie A22L@Lakehead B6M @ Birch B6M @ Moose Lake Yes Yes Yes Yes Yes Yes Yes Yes K3D@Rabbit Lake K3D@Dryden K3D@Rabbit Lake K3D@Dryden Yes Yes Yes Yes August 16, 2011 System Impact Assessment Report System Impact Studies In all cases, sufficient relay margin was observed under high flow east and flow west conditions with the new Domtar Dryden facility in-service. CAA ID 2010-420 33 August 16, 2011 System Impact Assessment Report Appendix A: Market Rules Appendix 4.2 CAA ID 2010-420 34 August 16, 2011 System Impact Assessment Report Appendix 4.2 – Generation Facility Requirements The performance requirements set out below shall apply to generation facilities subject to a connection assessment finalized after March 6, 2010. Performance of alternative technologies will be compared at the point of connection to the IESO-controlled grid with that of a conforming conventional synchronous generation unit with an equal apparent power rating to determine whether a requirement is satisfied. Each generation facility that was authorized to connect to the IESO-controlled grid prior to March 6, 2010 shall remain subject to the performance requirements in effect for each system at the time of its authorization to connect to the IESO-controlled grid was granted or as agreed to by the market participant and the IESO (i.e. the “original performance requirements”). These requirements shall prevail until the main elements of an associated system (e.g. governor control mechanism, main exciter) are replaced or substantially modified. At that time, the replaced or substantially modified system shall meet the applicable performance requirements set out below. All other systems, not affected by replacement or substantial modification, shall remain subject to the original performance requirements. Category Generation facility directly connected to the IESO-controlled grid, generation facility greater than 50 MW, or generation unit greater than 10 MW shall have the capability to: 1. Off-Nominal Frequency Operate continuously between 59.4 Hz and 60.6 Hz and for a limited period of time in the region above straight lines on a log-linear scale defined by the points (0.0 s, 57.0 Hz), (3.3 s, 57.0 Hz), and (300 s, 59.0 Hz). 2. Speed/Frequency Regulation Regulate speed with an average droop based on maximum active power adjustable between 3% and 7% and set at 4% unless otherwise specified by the IESO. Regulation deadband shall not be wider than ± 0.06%. Speed shall be controlled in a stable fashion in both interconnected and island operation. A sustained 10% change of rated active power after 10 s in response to a constant rate of change of speed of 0.1%/s during interconnected operation shall be achievable. Due consideration will be given to inherent limitations such as mill points and gate limits when evaluating active power changes. Control systems that inhibit governor response shall not be enabled without IESO approval. 3. Low Voltage Ride Through Ride through routine switching events and design criteria contingencies assuming standard fault detection, auxiliary relaying, communication, and rated breaker interrupting times unless disconnected by configuration. Category Generation facility directly connected to the IESO-controlled grid shall have the capability to: 4. Active Power Supply continuously all levels of active power output for 5% deviations in terminal voltage. Rated active power is the smaller output at either rated ambient conditions (e.g. temperature, head, wind speed, solar radiation) or 90% of rated apparent power. To satisfy steady-state reactive power requirements, active power reductions to rated active power are permitted. 5. Reactive Power Inject or withdraw reactive power continuously (i.e. dynamically) at a connection point up to 33% of its rated active power at all levels of active power output except where a lesser continually available capability is permitted by the IESO. A conventional synchronous unit with a power factor range of 0.90 lagging and 0.95 leading at rated active power connected via a main output transformer impedance not greater than 13% based on generator rated apparent power is acceptable. CAA ID 2010-420 35 August 16, 2011 System Impact Assessment Report 6. Automatic Voltage Regulator (AVR) Regulate automatically voltage within ±0.5% of any set point within ±5% of rated voltage at a point whose impedance (based on rated apparent power and rated voltage) is not more than 13% from the highest voltage terminal. If the AVR target voltage is a function of reactive output, the slope ∆V /∆Qmax shall be adjustable to 0.5%. The equivalent time constants shall not be longer than 20 ms for voltage sensing and 10 ms for the forward path to the exciter output. AVR reference compensation shall be adjustable to within 10% of the unsaturated direct axis reactance on the unit side from a bus common to multiple units. 7. Excitation System Provide (a) Positive and negative ceilings not less than 200% and 140% of rated field voltage at rated terminal voltage and rated field current; (b) A positive ceiling not less than 170% of rated field voltage at rated terminal voltage and 160% of rated field current; (c) A voltage response time to either ceiling not more than 50 ms for a 5% step change from rated voltage under open-circuit conditions; and (d) A linear response between ceilings. Rated field current is defined at rated voltage, rated active power and required maximum continuous reactive power. 8. Power System Stabilizer (PSS) Provide (a) A change of power and speed input configuration; (b) Positive and negative output limits not less than ±5% of rated AVR voltage; (c) Phase compensation adjustable to limit angle error to within 30° between 0.2 and 2.0 Hz under conditions specified by the IESO, and (d) Gain adjustable up to an amount that either increases damping ratio above 0.1 or elicits exciter modes of oscillation at maximum active output unless otherwise specified by the IESO. Due consideration will be given to inherent limitations. 9. Phase Unbalance Provide an open circuit phase voltage unbalance not more than 1% at a connection point and operate continuously with a phase unbalance as high as 2%. 10. Armature and Field Limiters Provide short-time capabilities specified in IEEE/ANSI 50.13 and continuous capability determined by either field current, armature current, or core-end heating. More restrictive limiting functions, such as steady state stability limiters, shall not be enabled without IESO approval. 11. Performance Characteristics Exhibit connection point performance comparable to an equivalent synchronous generation unit with characteristic parameters within typical ranges. Inertia, unsaturated transient impedance, transient time constants and saturation coefficients shall be within typical ranges (e.g. H > 1.2 Aero-derivative, H > 1.2 Hydraulic less than 20 MVA, H > 2.0 Hydraulic 20 MVA or larger, H > 4.0 Other synchronized units, X’d < 0.5, T’do > 2.0, and S1.2 < 0.5) except where permitted by the IESO.

ALL RIGHTS RESERVED PCT-217-PIA_Rev0_110419_SUMMARY.doc Page 1 of 3 PIA – Topping Turbogenerator Project Revision: R0 Disclaimer This Protection Impact Assessment has been prepared solely for the IESO for the purpose of assisting the IESO in preparing the System Impact Assessment for the proposed connection of the proposed generation facility to the IESO–controlled grid. This report has not been prepared for any other purpose and should not be used or relied upon by any person, including the connection applicant, for any other purpose. This Protection Impact Assessment was prepared based on information provided to the IESO and Hydro One by the connection applicant in the application to request a connection assessment at the time the assessment was carried out. It is intended to highlight significant impacts, if any, to affected transmission protections early in the project development process. The results of this Protection Impact Assessment are also subject to change to accommodate the requirements of the IESO and other regulatory or legal requirements. In addition, further issues or concerns may be identified by Hydro One during the detailed design phase that may require changes to equipment characteristics and/or configuration to ensure compliance with the Transmission System Code legal requirements, and any applicable reliability standards, or to accommodate any changes to the IESOcontrolled grid that may have occurred in the meantime. Hydro One shall not be liable to any third party, including the connection applicant, which uses the results of the Protection Impact Assessment under any circumstances, whether any of the said liability, loss or damages arises in contract, tort or otherwise. Revision History Revision R0 Date April 19, 2011 Change PCT-217-PIA_Rev0_110419_SUMMARY.doc Page 2 of 3 PIA – Topping Turbogenerator Project Revision: R0 EXECUTIVE SUMMARY Figure 1: ~16 MVA Turbo Generation Connection to HONI Transmission System It is feasible for Domtar Pulp and Paper Products to connect the proposed ~16 MVA steam generation at the location in Figure 1. PROTECTION HARDWARE The present protections on D5D can accommodate the increase in generation and will continue to function with the existing scheme for the Dryden TS terminal. PROTECTION SETTING The existing settings can cover the new scenario and require no change. TELECOMMUNICATIONS The existing telecommunication links can be retained to maintain the existing remote trip scheme. DOMTAR DRYDEN RESPONSIBILITIES The customer shall provide redundant distance protection scheme to cover faults on D5D (and on the alternate supply M2D when supplied by M2D) and shall be responsible to reliably disconnect their equipment for a fault on D5D (or M2D), even in case that a single contingency failure occurs in their P&C systems.
