Does EIA publish data on peak or hourly electricity generation, demand, and prices?
The U.S. Energy Information Administration (EIA) publishes regional, annual, and projected peak electricity load (or demand) data in Tables 8.6.A and 8.6.B. of the Electric Power Annual.
Peak summer and winter demand for individual utilities are available in the Operational Data file of the EIA Form 861 database files.
EIA does not publish hourly data on electricity generation, electricity demand, or electricity prices on a regular basis. The articles in the Learn more section below contain the related information and data that EIA has published.
Some Independent System Operators (ISO) or Regional Transmission Organizations (RTO) in North America publish data and charts with real-time or hourly generation data by type of fuel or energy source. The ISO/RTO Council (IRC) has links to the websites of its members.
