AI summary NS Power supports updating the capacity study prior to the next Integrated Resource Plan (IRP) analysis, focusing on the interactive effects of clean resources. Municipal load in certain areas is served by a wind farm not included in NS Power’s sourced wind generation. Due to increased firm peak demand and delays in the Wreck Cove LEM Project, NS Power will not meet the 20% PRM target for the 2024/2025 Winter period and will implement strategies like keeping Lingan 2 in cold reserve.
