The U.S. has gone on to install almost 26 GW of new generation capacity between January 2025 and August 2025, which is up marginally from almost 23 GW that was installed over the same period in the previous year, as per the most recent Federal Energy Regulatory Commission’s monthly infrastructure report.
As it has been for most of the past couple of years, solar has continued to dominate the new generation resources, comprising 2.7 GW out of the 4 GW brought online in August 2025 alone and 19 GW – around three-quarters of additional generation capacity in 2025.
As per the report, the FERC reissued a certificate for Williams Companies in order to construct and operate its Northeast Supply Enhancement Project. That expansion when it comes to the Transco gas pipeline from New Jersey to New York has also been revived after the talks between President Donald Trump and Governor Kathy Hochul in May 2025, as the Trump administration briefly went on to freeze the Empire Wind project. The White House, as well as the developer of the wind project, has gone on to tell the journalists that both sides reached a gas-for-wind deal, whereas Hochul has gone on to deny any such bargain.
It is well to be noted that the report shows momentum for the renewables to continue, in spite of the emphasis by the federal government on fossil fuels as well as nuclear. FERC happens to list 136 GW of high-probability additions till August 2028, with renewables, which are led by solar and followed by wind, comprising almost 84%. Natural gas accounts for around 15% when it comes to high-probability additions.
According to Ken Bossong, the executive director of the Sun Day Campaign, notwithstanding impediments that have been created by the Trump Administration as well as the Republican-controlled Congress, solar along with wind continues to add more generating capacity as compared to fossil fuels and nuclear power, and FERC foresees the role of renewable energy expanding in the coming three years, whereas the shares offered by coal, oil, natural gas, and nuclear all contract.
It is worth noting that large renewable projects that started operating in August 2025 include the likes of the 517 MW Outpost solar and storage project from Hecate Energy in Webb County, Texas; the 280 MW project by Gibson Solar in Gibson County, Indiana; and also, the expansions at the Eastland County, Texas’ Roadrunner Crossing Wind Farm totalling 254 MW.
While solar and wind made up almost all of the new generation capacity added in August 2025, a number of smaller gas generators had also come online that month, amounting to 888 MW. They include the likes of the 248-MW A.B. Brown expansion project in Posey County, Indiana, from Southern Indiana Gas & Electric Co.; the 245-MW Pioneer Generation Station expansion in Williams County, North Dakota, from Basin Electric Power Coop.; and also, the 188-MW Maxwell Peaker Plant in Caldwell County, Texas, by the Lower Colorado River Authority.
