The California Energy Demand Update (CEDU) 2024 Forecast is an update of electricity demand developed for the 2024 Integrated Energy Policy Report (IEPR) Update. CEDU 2024 incorporated the most recent historical electricity sales data, updates to economic and demographic drivers and anticipated electricity rates. Model revisions and new data for behind-the-meter photovoltaic (PV) generation, transportation electrification and data centers were implemented. Additional achievable scenarios for fuel substitution and transportation electrification were updated with the latest historical and policy trends. These changes were applied to the annual electricity forecast and the hourly and peak demand electricity forecasts.
The results were adopted by the Energy Commission at a business meeting on January 21, 2025. The adopted forecast is for the years 2024 to 2040, however some results for years 2024 to 2050 are included here for other planning purposes.
Demand Side Forecast
Baseline forecasts of annual energy and peak electricity demand to 2040. These forecasts consider only programmatic impacts that are approved and funded and that have a detailed implementation plan. Baseline forecasts can be paired with “additional achievable” scenarios to create managed forecasts suitable for planning.
