Total US Generation Capacity (mWh) by Generation Source
U.S. generation capacity by source tracks how much power the grid can produce from renewables, fossil fuels, nuclear, and batteries since 2019. Capacity trends signal future price pressure and reliability, which matters when choosing a long-term electricity provider.
Key Insights
U.S. electricity generation capacity has continued to expand since 2019, driven primarily by growth in natural gas and renewables. While fossil fuel capacity remains dominant, the mix is steadily shifting as wind, solar, and battery storage account for a growing share of new additions. Coal capacity continues to decline, reinforcing long-term structural changes in the U.S. power grid.
