RWE Commissions the 200-MW Stoneridge Solar Project in Texas

LCG, November 26, 2025--RWE announced today the commissioning of the Stoneridge Solar project, located in Milam County, Texas. The project capacity is 200 MW of solar power, plus a battery energy storage system (BESS) that provides 100 MW (200 MWh) of battery storage capacity. The BESS improves the supply of short-term, reliable, affordable electricity in ERCOT.

AEP, Buckeye Power to Install NOx Systems

LCG, Aug. 3, 2001--American Electric Power Co. and Buckeye Power Inc. announced yesterday their plans to construct new nitrogen oxide control systems at their jointly owned Cardinal Plant in Brilliant, Ohio.

AEP owns the 600 megawatt Unit 1 of the Cardinal facility, while Buckeye owns the 600 megawatt Unit 2 and the 630 megawatt Unit 3. AEP said it would spend about $65 million on the NOx systems while Buckeye estimated that its cost would be around $135 million.

The 34-year-old coal-fired Cardinal plant was the first-ever alliance of an investor-owned electric utility, AEP, and a member-owned electric generating and transmission company, Buckeye Power, an organization of 25 rural electric cooperatives, to build and operate a power plant to serve their respective electric customers.

AEP said installation of selective catalytic reduction systems will reduce nitrogen oxide emissions on each of the plant's three generating units by about 90 percent. Both companies are reducing NOx emissions as part of an effort to comply with new U.S. Environmental Protection Agency regulations.

Richard K. Byrne, president of Buckeye, noted that Units 2 and 3 represent all of the coops' generating capacity. "Installing SCR systems on each of these two units will enable Buckeye Power to be in full compliance with the EPA's new regulations that require reductions in nitrogen oxide emissions, he said."

John F. Norris, AEP's senior vice president of operations and technical services, commented that while the SCR technology being deployed on the three Cardinal units is the one on which the EPA relied to develop the new NOx rules, his company is continuing to explore new technological options that may ultimately prove to be more efficient and cost-effective.
