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.

Oklo and Siemens Energy Sign Agreement to Accelerate Power Conversion System for New SMR in Idaho

LCG, November 19, 2025--Oklo Inc. and Siemens Energy announced today that the parties have signed a binding contract for the design and delivery of the power conversion system for Oklo’s Aurora-INL (Idaho National Laboratory) nuclear small modular reactor (SMR). The agreement authorizes Siemens Energy to begin engineering and design work to expedite procurement of long-lead components and to initiate the manufacturing process for the power conversion system. Oklo’s expertise in advanced fission technology will be combined with Siemens Energy’s extensive industry experience with steam turbine and generator systems, with the ultimate goal of generating carbon-free, reliable electricity.

Plug Power Fuel Cells Pass Reliability Milestone

LCG, Nov. 8, 2000--Plug Power Inc. said this morning that its residential fuel cell had passed a key milestone by achieving a "mean time between failure" of more than 1,000 hours. The company is "beta testing" five of the RU1 development units.

That would indicate that half of the failures occur before 41 days have elapsed and half of them occur after 41 days.

According to Greg Silvestri, chief operating officer, Plug Power had a busy and productive summer. "We achieved significant milestones in system testing and reliability and built initial development units of our first commercial product design," he said.

That first commercial product, the RU1, is a 60-Hertz unit that produces power indistinguishable from that supplied by a utility. The units convert natural gas into hydrogen-rich fuel that is passed through the system's fuel cell stack where electricity is electrochemically generated. The fuel cell's power conditioner then converts the electricity into high-quality alternating current for normal household use.

During the summer, the company built 30 fuel cell systems, bringing the total to 91 systems builtso far this year. During the fourth quarter, the company will manufacture the initial prototype RU1 units, one of which is expected to be on display by GE Fuel Cell Systems in the GE Power Systems booth at PowerGen International next week.
