SPI's forecasted load in 2025 and 2026 are higher than in the prior forecast. Moreover, NSPI is forecasting higher RTR growth in the remainder of the forecast horizon, reducing NSPI's forecasted load. Second, NSPI reduced the estimated imp...
AI summary NSPI's 2025 and 2026 load forecasts show higher values than prior forecasts, but RTR growth is expected to reduce load. NSPI also reduced its estimate of new EV load and increased its forecast of load reduction from behind-the-meter solar. Continued DSM and energy efficiency efforts are expected to limit load growth despite customer growth and electrification of heating.

AI summary The document discusses assumptions used in fuel and purchased power forecasting with PLEXOS, including energy exports to New Brunswick, import pricing from New Brunswick, and modeling of surplus energy based on New England Power Pool's Hub prices.
III.B.2.b. Environmental Considerations in Unit Commitment and Dispatch Forecasting NSPI is subject to air quality regulations that dictate its fleetwide emissions of SO2, NOx, mercury, and GHGs. NSPI's F&PP forecasts incorporate these lim...
AI summary NSPI must comply with air quality regulations, which influence its unit commitment and dispatch forecasting. It uses tools like PLEXOS and PortOps to model emissions constraints, manage fuel blends, and incorporate OBPS cost adders for GHG emissions. Emissions compliance is reviewed by multiple teams, and adjustments are made to ensure adherence to environmental regulations.
Figure III-6: PLEXOS Assumptions - Q4 2025 Fuel and Purchased Power Forecast Group PLEXOS Assumptions Update Required Notes Update Received Date Lood Base Load forecast - Monthly demand and energy Yes Load unchanged from previous in 2026 a...
AI summary The document outlines assumptions and updates for the PLEXOS model related to load forecasting, hydro generation, tidal storage, and unit performance parameters for Q4 2025. Some updates are required, particularly for load forecasts and maintenance schedules, while others are based on historical data or unchanged from previous models.
that period, while the forecasted load exceeded actual load 84.8% of the time. NSPI provided its own MAPE results that do not match our MAPE calculations, which were calculated using NSPI's own data. Conclusion III-8: Further to Conclusion...
AI summary The text discusses NSPI's load forecasting challenges following a cyber event, reliance on PLEXOS for forecasting, emissions modeling practices, and QA/QC processes. It highlights discrepancies in MAPE results, manual forecasting post-cyber event, and the transfer of system planning responsibilities to the IESO.
Trucking, therefore, would allow Trenton's inventories to recover, particularly at unit 6, which was expected by NSPI to be "baseloaded" and a key generating unit to meet SO2 compliance requirements. The next instance of trucked coal occur...
AI summary NSPI issued an RFP for short-term trucking services in 2024 to address coal inventory shortages at Trenton due to an unexpected unit recall. Trucking up to 80,000 tonnes of coal was expected to prevent inventory levels from becoming negative and ensure compliance with SO2 requirements.
wable sources each year.504 NSPI receives renewable energy from its owned renewable facilities, including its wind and hydro resources, plus PHB, as well as third-party renewable generators, including 503 See Carbon Pricing Systems across...
AI summary NSPI sources renewable energy from owned and third-party facilities and manages emissions through fuel blending and emissions control equipment. Compliance with emissions limits is achieved through technologies such as low NOx burners, electrostatic precipitators, and sorbent injection systems.
of installed capacity from the NS Block; rather, the NS Block has been subject to frequent and extended capacity reductions, in some cases reducing capacity to zero for a period as long as one month. It is true that the makeup energy volum...
AI summary The NS Block has experienced frequent and extended capacity reductions, impacting NSPI's ability to rely on it for planning reserve margin. While NSPI receives advanced schedules of makeup energy from NLH, the underdeliveries from the NS Block, particularly during the Labrador Island Link's unavailability, have significantly limited its reliability as a capacity resource.
XII.C. Conclusions Conclusion XII-1: The sources of power that serve FAM customers continue to become more diverse and regionally-integrated as evidenced by continued increases in imports and third-party purchases, totaling 35.9% during th...
AI summary The document outlines conclusions regarding the diversification of power sources for FAM customers, NSPI's PPAs with renewable generators, and the increase in imported power, particularly from the Muskrat Falls project via the Maritime Link.
