Gas-Fired Power Plant Coming To Moundsville

Updated on Friday, Jan. 23, 2026, 10:30 a.m.

The development of a natural gas power plant in Moundsville, in Marshall County, is moving forward according to an announcement from Gov. Patrick Morrisey. 

Calpine LLC, a business unit of the company Constellation, is moving forward with a more than $1 billion dollar investment in West Virginia. The plant is expected to generate more than 500 megawatts of power.

The plant is expected to create more than 400 construction jobs along with approximately 25 permanent jobs once the power plant is operational.

“This is the kind of private-sector investment that drives long-term growth for West Virginia,” Morrisey said. “By expanding our energy infrastructure and strengthening our power grid, we are creating real opportunities for workers, supporting local communities, and positioning our state to meet the growing energy needs of the nation.”

The project was originally proposed in 2014 by a different developer, but it remained dormant for more than a decade.

“Calpine is moving forward with the project thanks to improved market conditions and Governor Morrisey’s 50 by 50 initiative,” said Suriyun Sukduang, Calpine vice president of Origination. “Our strong history of building and operating gas-fired generation makes us a strong partner for a community that will benefit from a more reliable electric power grid, local jobs, tax revenues, and targeted philanthropic support that improves education, workforce development, environmental projects, and economic opportunity.”

Currently the state generates roughly 16 gigawatts of power.

Calpine LLC operates 79 facilities with more than 27,000 megawatts of generation capacity, serving customers in 22 states and Canada.
