Comments on Nova Scotia Power’s 2025 Integrated Resource Plan Action Plan and Roadmap Update
Nova Scotia Energy Board
Project completed.
The Nova Scotia Energy Board engaged Synapse to review Nova Scotia Power 2025 Integrated Resource Plan (IRP) Action Plan Update. Synapse provided a summary report with its findings, with a focus on the following topics:
- Misalignment of proposed new combustion turbine additions between the IRP and other planning documents: The 600 MW of proposed CT additions in the action plan update is not supported by or aligned with prior IRP studies and reports.
- The need for Nova Scotia to conduct an updated Evergreen IRP as soon as possible: The last IRP modeling conducted by NSPI was in 2022/2023 and with the transition of resource planning responsibilities from NSPI to the Nova Scotia Independent Energy System Operator its imperative for the update to occur in a an expeditious manner.
- The reliability benefits and resource adequacy insurance of the Reliability Tie should have been better incorporated into the action plan modeling and evaluation.
- The need to evaluate alternatives to the Mersey hydro system in the next IRP and to update capital cost estimates.
