Does EIA publish data on peak or hourly electricity generation, demand, and prices?
The U.S. Energy Information Administration's (EIA) has two website tools that provide data and visualizations of electricity supply and demand on a national level and on regional levels. Both include hourly data and charts to illustrate fluctuations in supply and demand during selectable time periods. Electricity supply includes net electricity generation and electricity interchanges (transfers) between regions. Regions include the operational areas of the electric system balancing authorities that make up the U.S. electric grid.
- U.S. Electric System Operating Data tool provides hourly, daily, weekly, and monthly electricity supply and demand data and visualizations on national and regional levels.
- Hourly Electric Grid Monitor is a redesigned and enhanced version of the U.S. Electric System Operating Data tool. It incorporates two new data elements: hourly electricity generation by types of energy/fuel source and hourly sub-regional demand for certain balancing authorities in the Lower 48 states. The Hourly Electric Grid Monitor tool also provides enhanced and more flexible options for visualizing the data, and it allows users to create custom dashboards that can be saved and shared. Read more about the Hourly Electric Grid Monitor.
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.
Data on peak summer and winter demand for individual utilities are available in the Operational Data file of the Form EIA-861 database files.
EIA does not publish hourly electricity price data, but it does publish wholesale electricity market information including daily volumes, high and low prices, and weighted-average prices on a biweekly basis.
