Electric power data are collected on survey instruments. Data collection is mandated by Congress to promote sound policymaking, efficient markets, and public understanding. The most widely used data are disseminated in reports, such as the Electric Power Monthly and the Electric Power Annual. Publicly available electric power data is available down to the plant level in the Electricity Data Browser and in detailed spreadsheets by survey below.
