Energy-Efficiency Forecast

Access the ISO’s forecast of long-term savings in peak and energy use for the region and for each state stemming from state-sponsored energy-efficiency (EE) programs. Examples of EE measures include the use of more efficient lighting, motors, refrigeration, HVAC equipment, control systems, and industrial process equipment.

This table includes data from the 2020 EE Forecast. To learn more about how EE, along with solar power, are helping to reduce annual energy use and shave peak demand, see the Key Stats: Electricity Use page.

About the Forecast Development

The ISO’s regional forecast of EE resources—the first of its kind—has been developed annually since 2012 with stakeholder input from the Energy-Efficiency Forecast Working Group. The EE forecast is:

• used in ISO studies looking beyond the Forward Capacity Market timeframe, such as long-term transmission planning studies and economic planning studies.
• incorporated into the CELT Report and Regional System Plan.

Data used to create the forecast originates from state-regulated utilities, energy-efficiency program administrators, and state regulatory agencies. The EE forecast is based on averaged production costs, peak-to-energy ratios, and projected budgets of state-sponsored energy-efficiency programs. Information used to develop the forecast can be found on the Energy-Efficiency Forecast Working Group page.
