Hydroelectric Power Plants in Alabama: FAQ
- How many hydroelectric power plants are in Alabama?
- 23, with 3 GW of nameplate capacity between them, spread over 16 counties. That is the EIA-860M operating count for 2026-07.
- Is there a map of Alabama hydroelectric power plants?
- Yes — the map above. Each dot is one hydroelectric power plant, sized by nameplate capacity and placed at the coordinates EIA files for it.
- Which is the largest hydroelectric power plant in Alabama?
- Wilson Dam, at 667 MW. The table is sorted largest first, so the rest follow it.
- Is there a hydroelectric power plant near me in Alabama?
- The county roll-up below groups every plant by county, which is the quickest way to find the one closest to a given town.
- Which grid operator runs Alabama's hydroelectric power plants?
- No single ISO or RTO covers most of them. EIA files each plant against its own balancing authority, which in Alabama is largely a vertically integrated utility rather than an organised market.
- How current is this, and what is left out?
- EIA-860M for 2026-07. Conventional hydroelectric. Pumped storage is counted separately. Plants below 1 MW are not surveyed by EIA and so are absent; retirements and additions after 2026-07 arrive with the next monthly release.
