About this data
All numbers on this page come from public datasets published by the U.S. Energy Information Administration, the U.S. Environmental Protection Agency's eGRID program, and the U.S. Census Bureau. Rate and bill figures are from EIA Form 861 (annual) and Form EIA-861-M (monthly). Generation data is from EIA Form 923. Plant inventory and retirement schedules come from EIA Form 860. Emissions are from EPA eGRID, the most recent published edition.
Data is refreshed weekly. EIA typically publishes annual data with a 10-month lag — for example, full-year 2026 data became available in late 2027.
