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.

AmerenUE Submits Application to NRC for New Nuclear Reactor

LCG, July 31, 2008--AmerenUE submitted Monday a combined Construction and Operating License Application (COLA) to the Nuclear Regulatory Commission (NRC) to build a 1,600 MW nuclear reactor at its Callaway Plant in Missouri. The company projects that the additional power supply will need to commence operations in the 2018-2020 timeframe.

AmerenUE stated that it has not yet made a decision to install a second nuclear reactor; however, by pursuing the NRC approval now, AmerenUE will better preserve the option to build carbon-free, nuclear capacity in the future. Moreover, it will place the company in a position to seek nuclear-specific federal loan guarantees and production tax credits provided for in the Energy Policy Act of 2005.

The existing Callaway Plant consists of a single reactor that has a net generating capacity of 1,126-MW and began service December 1984. The site is located about twenty-five miles northeast of Jefferson City and was initially developed with the idea of adding a second unit in the future.

AmerenUE selected AREVA's U.S. Evolutionary Power Reactor (EPR) design. The EPR is a Generation III+ design based upon AREVA's 1,600-MW, European EPR that is now being deployed in Europe. In 2007, AmerenUE announced that the company had signed an agreement with UniStar Nuclear Energy to help prepare a COLA. UniStar Nuclear Energy was formed in 2007 as a strategic joint venture between Constellation Energy and EDF Group, a leader in nuclear power that owns and operates 58 nuclear reactors in France.

The selection of the EPR adds momentum to AREVA's presence in the U.S. Early this year, UniStar Nuclear Energy announced that it had engaged an AREVA-Bechtel Power consortium to start developing the detailed design engineering for UniStar's proposed fleet of advanced nuclear power plants in the United States that would use AREVA's U.S. EPR design.

UniStar's targeted sites include Constellation Energy's existing Calvert Cliffs Nuclear Power Plant in Lusby, Maryland, Constellation's existing Nine Mile Point Nuclear Station and, working with PPL Corporation, a site near the Susquehanna nuclear power plant in Pennsylvania.

AREVA filed its application to certify the U.S. EPR design on December 11, 2007, and in February the NRC accepted the application for review. The NRC will conduct a technical review and will issue a Safety Evaluation Report after all technical and safety questions are addressed. The NRC may then certify the design with an agency rulemaking. The NRC?s Office of New Reactors expects the review work will continue at least into 2011.
