CEDU 2024 Demand Side Modeling

Products from the CEDU 2024 Forecast

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.

Demand Side Forecast

Baseline forecasts of annual energy and peak electricity demand. 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.

Electricity sales projections by CEC forecast sector and planning area. The data contains forecasts for each of the 2024 Integrated Energy Policy Report (IEPR) Update Managed Forecasts. More details regarding the CEC managed forecasts can be found in Chapter 3 of the 2024 Integrated Energy Policy Report (IEPR) Update. CEC planning areas “VEA” and “OTHER” are omitted from the data.

Electricity demand forecast results disaggregated to load-serving entities and balancing authorities consistent with the California Energy Commission's 2024 Integrated Energy Policy Report (IEPR) Update.

Retail electricity rate forecasts developed for the California Energy Demand Update Forecast, 2024 -2040 and supporting data.

Factors which account for electric grid power losses for the transmission and distribution system. For each factor: [load at customer meter] x [factor] = [BA system load]

Transportation Forecast

Annual statewide stock forecast of vehicles by duty for the baseline forecast and additional achievable transportation electrification (AATE) scenario 3, which was included in the 2024 Integrated Energy Policy Report (IEPR) Update.

  • Statewide Vehicle Populations (pending)

Annual transportation electricity demand across various utility territory regions, as well as across the various planning scenarios and baseline forecast.

  • Utility Region Forecast - PEV Energy (pending)

Annual vehicle stock across various utility territory regions, as well as across the various planning scenarios and baseline forecast.

  • Utility Region Forecast – PEV Stock (pending)

Annual transportation energy demand across the various planning scenarios and baseline forecast. Considers electricity and other transportation fuels.

  • Statewide Fuel Demand Forecast (pending)
