HOUSTON, TX, September 30, 2021 – PROENERGY announced that its latest PowerFLX turnkey power plant solution—the 288-MW Mark One facility for WattBridge Energy, LLC— has started construction in Brazoria County. Anticipated to be online by November 2022, the plant will support renewable energy development and deliver reliable power during peak-demand times, including severe heat waves and winter weather.

The Mark One project will be powered by six LM6000 gas-turbine packages. A subsidiary of PROENERGY, WattBridge is among the most prolific owner/operators of LM6000 aeroderivative engines in the world. Each plant—a true turnkey PROENERGY peak-power solution that includes the complete balance of plant from engine to water treatment to high-voltage substation—is installed with the vision to accelerate renewable energy growth.   

“Facilities like Mark One serve as the bridge between a hydrocarbon-dominant past and a fully renewable future,” says Jeff Canon, PROENERGY CEO. “In addition to serving as a critical energy resource during peak-demand events, WattBridge facilities are key enablers for wind and solar-generation growth by filling gaps in energy supply with reliable, reduced-emission power generation.”

Project speed is enabled by a unique collaborative model that spans major equipment supply, EPC (engineering, procurement, and construction) execution, government, regulatory bodies, and a strategic mix of business partners.

“We’re proud to have placed this project on the fast track for the citizens of Brazoria County by collaborating with supportive and motivated teams at Brazoria County, our financing partners, our gas supplier, ERCOT, and our offtake client, Shell Energy North America,” says WattBridge President, Mike Alvarado. “By compiling an ace team of expertise across the board, the Mark One project will accelerate from close of financing to supporting peak-power demand in just 16 months.”
