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.

DOE Clears the Path to Build Coal Plant Employing IGCC Technology

LCG, April 3, 2007--The Department of Energy (DOE) announced today that it has executed a Record of Decision that, according to the DOE statement, "clears the path for construction of a $569-million, 285-megawatt coal-fired power plant that will be one of the cleanest, most efficient plants of its kind in the world." The new plant will be built near Orlando, Florida at the existing Stanton Energy Center that is owned by the Orlando Utilities Commission (OUC).

The new coal plant will employ an integrated gasification-combined cycle (IGCC) technology based on the transport gasifier that Southern Company and others have been developing at the Power Systems Development Facility near Wilsonville, Alabama. The transport gasifier offers a simpler method to generate power from coal and is cost-effective when handling low rank coal, as well as coals with high moisture or high ash content. The DOE will provide a $235 million federal grant for the development of the advanced coal plant.

The new facility will be co-owned by Southern Power Company (the unregulated subsidiary of Southern Company), OUC, and Kellogg, Brown and Root. Operations of the new facility had been planned previously announced to commence in 2010.

The project is one of three, demonstration projects receiving funding through the federal Clean Coal Power Initiative (CCPI), a 10-year, $2-billion demonstration program designed to improve the environmental performance of coal-fired power plants in the United States. The other two projects are Excelsior Energy Inc. and ConocoPhillips? 531-MW Mesaba Energy Project in Minnesota, and the Pegasus Technology Project, which combines Pegasus Technologies Inc. with Texas Genco to demonstrate technology advancements to reduce emissions.

Southern Company's wholly owned utility, Mississippi Power Company, is also developing an advanced coal plant. Last December, plans were announced to build a 600-MW power plant fueled by lignite in Kemper County, Mississippi that would use an advanced gasification technology developed by Southern Company. The estimated cost of the facility is approximately $1.8 billion. The project is to receive over $133 million in tax credits from the DOE as a result of the National Energy Policy Act of 2005. The Mississippi plant is scheduled to commence operations in June 2013.
