LCG, April 24, 2025--Exxon Mobil Corporation (ExxonMobil) announced yesterday an agreement with Calpine Corporation (Calpine) to transport and permanently store up to 2 million metric tons per annum (MTA) of CO2 from Calpine’s Baytown Energy Center, a natural gas-fired facility located near Houston, Texas. This is part of Calpine’s Baytown Carbon Capture and Storage (CCS) Project that is designed to add CCS for the facility’s CO2 emissions. The Calpine facility could then provide a 24/7 supply of low-carbon electricity to the Texas grid plus steam to nearby industrial facilities.

AEP Plans to Retire 500-MW Coal-Fired Unit in Indiana
LCG, September 18, 2013--American Electric Power (AEP) announced yesterday that it plans to retire its 500-MW coal-fired Tanners Creek 4 electric generating unit in Lawrenceburg, Indiana.
AEP previously announced its decision to retire Tanners Creek Units 1-3 (495 MW) in June 2011. All four generating units at Tanners Creek will be retired by mid-2015. The plant was commissioned in 1951.
In response to the need to comply with new environmental regulations, AEP has now announced plans to retire 7,176 MW of coal-fueled generation by early 2016.
According to AEP's announcement, an option to refuel Tanners Creek 4 with natural gas was evaluated; however, the projections for limited electricity demand growth, combined with the amount of generation currently available to serve Indiana Michigan customers, led to the conclusion that it was financially unfeasible.
"The decision to retire Tanners Creek 4 was made as part of our ongoing analysis of resource needs and environmental compliance costs as part of our disciplined approach to capital investment. Based on relatively flat electricity demand and the fact that our Indiana Michigan Power customers don't need additional generation at this time, we've determined that the cost of refueling Tanners Creek 4 is not the right capital investment," said AEP's president and chief executive officer.
In July, AEP announced a similar retirement plan for its 585-MW coal-fired Muskingum River Plant Unit 5 located in Ohio. Given the cost of compliance with environmental regulations and current market conditions, AEP determined that it is unlikely to make the capital investment to refuel the unit to natural gas. AEP had previously announced its intent to retire Muskingum River Units 1-4 (840 MW) in 2015. The Muskingum River Plant was commissioned in 1953.
