Duke Energy’s Large-Scale Powergen Expansion Adding 14 GW by 2031
Duke Energy, headquartered in Charlotte, N.C., is one of the largest U.S. energy holding companies, serving 8.7 million electric customers and 1.8 million gas customers across six states. While the company dabbles in unreliable renewables like solar and wind, its bread-and-butter, go-to source for new electric power generation is natural gas, which it gets from the Marcellus/Utica. We’ve reported on many of Duke’s announced new gas-fired power plant projects (see our stories here). The company recently issued its first quarter 2026 report, which is a good opportunity for us to share a detailed list of the active gas-fired power plant and pipeline projects Duke is pursuing.

Good news! The Public Service Commission (PSC) of South Carolina approved a joint application by Dominion Energy and Santee Cooper to build Canadys Station, a natural gas combined-cycle facility in Colleton County. The plant will generate approximately 2,200 megawatts (2.2 GW) — enough to power over one million homes — addressing the state’s growing energy demand. It will be built on the site of a former Dominion Energy coal plant, roughly 40 miles northwest of Charleston (the “Lowcountry” region), eliminating the need for new land clearing. 
Oberlin, Ohio, officials are weighing a proposal to amend the city’s Community Bill of Rights to allow Dominion Energy Ohio to build a gas pipeline connection to a planned eco-industrial park, unlocking possible state support. Environmental groups and students at Oberlin College (neither of which pay any property or income taxes in Ohio, meaning they don’t have a say) argue the change would weaken Oberlin’s anti-fossil-fuel commitments and revive ties to Enbridge, whose NEXUS pipeline previously “divided” the city. City officials and utility experts counter that renewables alone are not yet feasible, citing constraints on electric capacity and on wind, solar, and geothermal options. 
In March, South Carolina regulators approved Duke Energy’s proposal to build a 1.4-gigawatt (GW) natural gas-fired power plant in Anderson County, marking the utility’s first new generation project in the state in a decade (see 
In January, MDN broke the news that Duke Energy is considering constructing a 1,360-megawatt natural gas power plant on 1,600 acres in Davidson County, North Carolina (see 
Utility company Spire Inc. (based in St. Louis, MO) successfully finalized its $2.48 billion acquisition of Duke Energy’s Piedmont Natural Gas utility business in Tennessee on March 31, 2026. Rebranded as Spire Tennessee, the utility becomes the state’s largest investor-owned natural gas provider, serving over 200,000 customers in the Nashville region via 3,800 miles of pipeline. Approximately 200 former Piedmont employees joined Spire. The natural gas that supplies Tennessee mostly comes from the Marcellus/Utica. 
Anti-fossil fuelers are raising concerns (and stoking fear with county residents) about a potential Duke Energy natural gas power plant in Davidson County, NC, after the project appeared in the company’s long-range planning documents. We first told you about this project three weeks ago (see 
Duke Energy, headquartered in Charlotte, N.C., is one of the largest U.S. energy holding companies, serving 8.7 million electric customers and 1.8 million gas customers across six states as of early 2026. While the company dabbles in unreliable renewables like solar and wind, its bread-and-butter, go-to source for new electric power generation is natural gas, which it gets from the Marcellus/Utica.

Cayuga Station, owned by Duke Energy, is a three-unit coal-fired power plant built between 1970 and 1993 in Vermillion County, Indiana. The existing plant produces up to 1,040 megawatts (MW) of electricity. Earlier this year, Duke filed a request with the Indiana Utility Regulatory Commission (IURC) for permission to build two new gas-fired units at the Cayuga site to replace the coal-fired units (see
