The United States has 54 operating nuclear power plants with 94 reactors in 28 states, according to the U.S. Energy Information Administration's generator inventory for August 2026. Two shut plants are being restarted, and two new ones are planned. Click a plant for its reactors, capacity, operator and the year it first came online, or open Filters.
What the map shows
- Vogtle in Georgia is the largest, at about 4,700 megawatts across four reactors. Its Unit 4, which entered service in 2024, is the newest reactor in the country. Palo Verde in Arizona (about 4,200 MW) and Browns Ferry in Alabama (about 3,900 MW) are next.
- Illinois has the most plants: six, all operated by Constellation. Pennsylvania and South Carolina have four each.
- The oldest operating reactor is Nine Mile Point Unit 1 in New York, online since 1969. Dresden and Point Beach followed in 1970.
- 19 plants have a single reactor; most of the rest have two.
- Two plants are being brought back (orange pins): Palisades in Michigan, where fuel loading began in August 2026 with no restart date yet, and Crane Clean Energy Center, the former Three Mile Island Unit 1 in Pennsylvania, which Constellation is targeting for 2027.
- Two are planned (green pins): TerraPower's Kemmerer plant in Wyoming, listed for 2030, and Project Matador in Texas, listed for 2031.
- The Western U.S. has few: Diablo Canyon in California, Palo Verde in Arizona and Columbia in Washington are the only operating plants west of Kansas.

How this map was made
Every plant, its location, reactors, capacity, operator and status come from the U.S. Energy Information Administration's monthly generator inventory (Form EIA-860M, August 2026), the federal government's own record of every power plant. The restart and planning details come from the operators and news reports from October 2026. EIA's summary page (March 2026) counts 57 plants and 96 reactors, including the two being restarted; this map shows the 56 sites in EIA's August 2026 generator inventory, plus the two planned plants.
