LCG, April 29, 2025--Officials from the U.S. Environmental Protection Agency (EPA) and Texas Railroad Commission (RRC) signed a memorandum of agreement (MOA) today outlining the state’s plans to administer programs related to carbon storage wells, known as Class VI wells. The MOA signing is a required step in the RRC’s application to be granted authority to permit Class VI wells in the state of Texas. EPA is currently preparing a proposed approval of RRC’s primacy application.

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.

TVA Plans to Acquire Power Plant to Increase Its Combined-Cycle Gas Fleet
LCG, July 8, 2011--The Tennessee Valley Authority (TVA) announced yesterday that it has negotiated an agreement to buy, subject to TVA board of directors' approval, the 968-MW Magnolia Combined Cycle Gas Plant in northern Mississippi from Kelson Limited Partnership, a wholly owned subsidiary of Kelson Energy Inc.
The closing on the acquisition is also subject to approval of the Federal Energy Regulatory Commission (FERC), among other conditions. Terms of the deal were not disclosed; however, it was stated that the purchase price will be less than half the cost of new construction.
TVA has purchased power from the Magnolia Combined Cycle Gas Plant since it began operations in 2003. The plant, located near Ashland, Mississippi, is in the TVA service area and is connected to the TVA grid. Kelson acquired the plant in 2005.
TVA stated that Magnolia will be its third combined-cycle gas plant. The other two are the new Lagoon Creek plant and the Southaven plant, which is jointly owned with Seven States Power Corp. A fourth combined-cycle plant, John Sevier, is under construction and scheduled to begin operation next year. TVA also operates a fifth plant, Caledonia, under a long-term lease agreement.
TVA's senior vice president of Strategy & Planning stated, "TVA continually evaluates our options to ensure a reliable, competitively priced supply of power for the people of the Tennessee Valley. The Magnolia plant offers a strong strategic, operational and financial fit for TVA and its vision to be a leader in low-cost and cleaner energy by 2020."
In August of last year, TVA announced that, beginning this year, it will idle nine coal-fired units with a combined electric generating capacity of approximately 1,000 MW as part of its strategy to replace or retire older, less-efficient, coal-fired units as a means of reducing carbon and other emissions from its generation portfolio. At the time, TVA's President stated, "Much of our stakeholder input and other assessments point toward a greater reliance on nuclear power and energy efficiency and less reliance on coal....Replacing some coal with other, cleaner fuel sources allows a reduction in air emissions including carbon. One of TVA's key goals is to improve air quality."
TVA's Integrated Resource Plan, which was formally presented to its board of directors in April 2011, was developed over two years, with extensive business, technical and economic analysis and public input. TVA's plan recommends a strategic direction focusing on a diverse mix of electricity generation sources, including nuclear power, renewable energy, natural gas and energy efficiency, as well as traditional coal and hydroelectric power.
