LCG, April 2, 2026--Southwest Power Pool (SPP) today announced that the expansion of its service territory into the Western Interconnection has been a success. The milestone makes SPP the first regional transmission organization (RTO) with services spanning the Eastern and Western Interconnections. Its member organizations, which cover all or part of 17 states, can now benefit from a more operationally and geographically diverse integrated system.

LCG, March 31, 2026--Holtec International yesterday announced that it successfully completed a milestone test necessary to return Holtec's Palisades Nuclear Generating Station to service. The 805-MW pressurized water reactor (PWR) is located in Michigan and was shut down by Entergy in May 2022. Holtec acquired the facility in June 2022 and has pursued a path to return the plant to service.

AEP Pushing Forward with Planned IGCC Plants in Ohio and West Virginia
LCG, October 3, 2006--American Electric Power (AEP) announced that it filed environmental permit applications with Ohio and West Virginia to build new, coal-fired, electric generating plants that employ an advanced, Integrated Gasification Combined Cycle (IGCC) design. Applications were filed with the Ohio Environmental Protection Agency and the West Virginia Department of Environmental Protection for IGCC plants AEP plans to construct in Meigs County, Ohio, and Mason County, West Virginia.
AEP is awaiting final regulatory approval regarding cost recovery and expects to complete site-specific engineering and design work by the end of this year. Given acceptable regulatory approval, AEP's plans call for construction of the Ohio plant to commence first, with work in West Virginia following approximately two years later. Previous schedules announced by AEP called for a target operational date of 2010 for the Ohio plant.
AEP's Ohio operating company filed with the PUCO for cost recovery in March 2005 to build an IGCC plant in Meigs County, Ohio. The proposed plant would have an electric generating capacity of 629 MW. AEP's Appalachian Power subsidiary filed an application in January 2006 with the Public Service Commission of West Virginia seeking authority to construct a similar plant adjacent to AEP's Mountaineer Plant near New Haven. AEP signed an agreement with GE Energy and Bechtel to estimate the cost and equipment needs for building both the Ohio and West Virginia facilities.
The IGCC process converts coal into a synthesis gas and minimizes most of the sulfur 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.
In general, the improved thermal efficiency and reduced emissions of an IGCC plant are expected to provide benefits that may out-weigh the higher capital costs over the economic life of the plant. In addition, the IGCC design is expected to provide for a more cost-effective means to capture carbon dioxide (CO2) relative to traditional coal plants.
