About This Dataset
Largest Geothermal Power Stations in the World 2026
The biggest geothermal power stations in operation in 2026, ranked by installed capacity in megawatts. Geothermal plants need particular geology - volcanic heat close enough to the surface to reach by drilling - so the map of large stations follows plate boundaries rather than demand.
Analysis
The Geysers in the United States is the largest at 1,517 MW, 1.85 times the 820 MW of Cerro Prieto. The 10 stations here total 5,724 MW. 3 of them are in the United States, and 7 countries are represented in total. The smallest on the chart, Darajat, is rated at 255 MW, 17% of the leader.
