AI summary NS Power explains that evaluating wind and cloud cover trends is relevant to energy use and peak demand forecasting. While hourly cloud cover forecasting is impractical without granular data, historical trends and existing load forecast models can inform decisions. Operational dispatch models already use cloud cover as a variable, though limitations in data granularity exist.

AI summary NS Power’s 2024 load forecast and new customer budget for distribution planning show inconsistencies. The residential load forecast includes 7,021 new customers based on the Conference Board’s housing data, while distribution planning uses a lower figure of 4,374 new customers. Exhibits and undertakings are cited to support these discrepancies.
