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.

AEP, Bechtel and GE Announce New IGCC Project

LCG, September 30, 2005--American Electric Power (AEP) announced yesterday that it has signed an agreement with GE Energy and Bechtel Corporation to develop the engineering and design process for a new, coal-fired, electric generating plant that employs an Integrated Gasification Combined Cycle (IGCC) design. AEP stated that it expects that this preliminary engineering phase for the 600-MW plant will require 10 to 12 months.

AEP's Ohio operating company filed for cost recovery March 18, 2005, with thePublic Utilities Commission of Ohio to build an IGCC plant in Meigs County, Ohio. AEP Ohio anticipates a decision from the Commission by the end of 2005. Given positive results from this initial phase and from related regulatory activities, AEP stated that operations of the new plant could commence in 2010. AEP plans to build at least one more 600-MW plant that employs the IGCC design in its eastern operating area by 2013.

The IGCC process converts coal into a synthesis gas and minimizes most of thesulfur dioxide (SO2), nitrogen oxides (NOx), mercury (Hg) and other emissions before the gas fuels a combustion turbine generator. The hot exhaust gas from the turbine heats water to produce steam to power a steam turbine and generate electricity a second time.

Cost estimates for IGCC plants tend to be somewhat higher than for more traditional supercritical or subcritical pulverized coal plants. However, the improved thermal efficiency and reduced emissions are expected to provide benefits that may out-weigh the higher capital costs over the economic life of the plant. Furthermore, relative to traditional coal plants, the IGCC design is expected to provide for a more cost-effective means to capture carbon dioxide (CO2).

Last October, GE Energy and Bechtel announced their intent to form an alliance to develop a standard commercial offering for optimized IGCC projects in North America. GE Energy has also purchased the ChevronTexaco gasification technology business, whose technology has been applied to a number of IGCC power plants. Last May, GE Energy and Bechtel signed an agreement with AEP to estimate the cost and equipment needs for building a new, 600-MW IGCC plant, with sites identified in Ohio, West Virginia and Kentucky.

Last week, Cinergy/PSI announced similar plans to start preliminary engineering and design of a new, 600-MW IGCC generating station in partnership with Vectren Corporation. The companies also planned to negotiate a contract with GE Energy and Bechtel for the preliminary engineering study. Cinergy and Vectren stated that there are several sites under consideration sites in Indiana. The targeted site is PSI's 160-MW Edwardsport coal-fired generating station near Vincennes.
