- Developer
- NextEra Energy Resources, a subsidiary of NextEra Energy Inc. of Juno Beach, Florida. NextEra says the U.S. and Japan would own the project while NextEra develops, builds and operates it for fees without investing its own capital.
- Tenant
- No customer has been named. The Commerce Department says the plant could serve up to 3.5 gigawatts of large-load demand, and NextEra says it's engaging potential customers and that large-load customers will pay their fair share.
- Current stage
- NextEra, the Commerce Department and Japan finalized commercial terms on August 12, 2026, releasing an initial $3.3 billion for the Texas and Pennsylvania projects together for turbine down payments and choosing construction contractors, and NextEra said on October 21, 2026 that it has signed definitive agreements for three federal hubs, one of them in Pennsylvania. We haven't found a NextEra release naming the site. A September 2, 2026 Washington Examiner column reported the Pennsylvania plant, called the East Riverside Energy Center, would be built in Luzerne Township, Fayette County, on about 150 of roughly 700 acres along the Monongahela River that NextEra holds purchase options on. The column described three gas power blocks of about 1,250 megawatts each coming online in 2030, 2031 and 2032, and Fayette County Commissioner Scott Dunn has publicly said the plant is coming to the county. No local zoning or state permit filings tied to the site have been reported.
- Decision body
- Not yet known, because the site hasn't been disclosed. NextEra says the project remains subject to permitting and regulatory approvals, which would include the host municipality or county and the Pennsylvania DEP. The plant would connect to the PJM grid, and the federal side is run by the U.S. Department of Commerce under the U.S.-Japan trade agreement.
- Top issues
- Where the plant will go and who will decide; air emissions from a 4.3-gigawatt gas plant; how much Marcellus and Utica shale gas it would burn; water for cooling; whether data center customers or regular ratepayers end up paying for grid upgrades; and NextEra's related MARL transmission line.
- Key opponents
- No organized opposition to South Mon itself has been reported, largely because its location is secret. The Center for Coalfield Justice keeps a page on the project, criticizes the secrecy around it, and links it to NextEra's proposed MidAtlantic Resiliency Link transmission line through Fayette and Greene counties, which farmers and local officials are fighting.
- Key supporters
- U.S. Sen. Dave McCormick called the $17 billion South Mon project "historic," and Commerce Secretary Howard Lutnick announced the first $3.3 billion for it and NextEra's Texas hub. President Trump approved the projects under the U.S.-Japan trade deal.
How we got here
The White House announced a $17 billion gas-fired power plant for southwestern Pennsylvania on March 19, 2026, and the next day the Commerce Department named it Project South Mon and NextEra said its Texas and Pennsylvania hubs had been selected under the U.S.-Japan trade deal. In its April 23, 2026 earnings release NextEra described 9.5 gigawatts of gas generation across the two states, owned by the U.S. and Japan. The Center for Coalfield Justice started a tracking page in May. On Aug. 12, 2026, the parties finalized commercial terms and released an initial $3.3 billion, and Sen. McCormick placed South Mon in the Mon Valley region. On Oct. 21, 2026, NextEra said definitive agreements had been signed for its federal hubs, including one in Pennsylvania.
Update, October 26, 2026. On September 2, 2026 a Washington Examiner column reported that NextEra's Pennsylvania plant, the East Riverside Energy Center, would be built in Luzerne Township, Fayette County, along the Monongahela River, and on September 7, 2026 Energy Central reported that Fayette County Commissioner Scott Dunn had posted that NextEra announced a $13 billion, 3.75-gigawatt gas plant in the county.
