AI summary The 2025 Load Forecast Report indicates increased near-term Net System Requirement (NSR) due to changes in Renewable to Retail (RTR) sales, with mid- to long-term growth reduced by lower EV sales, higher RTR and behind-the-meter solar adoption, and Demand Side Management (DSM) initiatives. Annual NSR is projected to decrease by 0.2% between 2025–2035, while peak demand remains stable near-term despite electrification trends.

R activities will reduce the peak. Compared to 2024, the peak forecast is very similar in the near 17 term (the delayed start of RTR does not impact the peak forecast as there is no decrease to the DATE: June 27, 2025 Page 8 of 94 REDACTED...

AI summary The 2025 Load Forecast Report indicates system peak demand will increase by 1.1% annually, with near-term forecasts similar to 2024 but long-term adjustments due to revised EV impact. RTR activities are expected to reduce peak demand without affecting short-term forecasts.

AI summary The response explains that the 2024 NSR growth was lower due to warmer-than-normal winter weather, leading to a lower actual growth compared to the forecast. The 2025 and 2026 forecasts use normal weather assumptions, hence higher than the 2024 overestimation. The System Peak drop in 2024 was due to an extreme 2023 peak and actual conditions, with NS Power expecting a return to the forecast track.

AI summary The report forecasts a 0.2% annual decrease in NSR between 2025-2035, contrasting with a 28% increase in system peak demand by 2035. While NSR forecasts align closely with actual results, system peak predictions show significant variance, attributed to electrification trends and model assumption changes.
