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.

Construction Commences on Kemper County IGCC Power Plant

LCG, December 17, 2010--Mississippi Power, a subsidiary of Southern Company, yesterday held the ground breaking ceremony for the Kemper County IGCC (Integrated Gasification Combined Cycle) Plant in Mississippi. The project is estimated cost to $2.4 billion and is scheduled to commence operations in 2014.

The 582-MW Kemper County IGCC Plant incorporates the Transport Integrated Gasification (TRIG?) technology, developed by Southern Company, KBR and the U.S. Department of Energy, to gasify local lignite resources for combustion in a combined cycle facility.

"The Kemper County IGCC plant will put to work a four billion ton reserve of lignite, an underutilized resource in Mississippi," said Ed Day, president and chief executive officer of Mississippi Power. "Mississippi lignite is the lowest cost fuel source available, and its price stability is the key to what makes the project the best option to serve our customers? growing energy demands."

The design includes carbon capture system estimated to capture 65 percent of carbon dioxide, which would make the CO2 emissions comparable to that of a natural gas combined cycle plant.

Earlier this month two other IGCC projects made headway. First, EmberClear announced that all of the necessary permits for the development and construction of the 270-MW, Good Spring IGCC Project were received by its joint venture, Future Power PA, Inc. (FPPI). The Good Spring IGCC project will be built in Northeastern Pennsylvania and will also utilize nearby coal supplies. The plant design and coal gasification process is based upon the GreenGen project in Tianjin, China.

In addition, the Illinois State House approved Tenaska's proposed Taylorville IGCC project, which will employ Siemens AG's IGCC technology to gasify Illinois coal for fuel to generate electricity in the planned 602-MW facility. Tenaska expects the coal gasification process will allow over 50 percent of the CO2 produced to be captured.
