LCG, September 12, 2025--Entergy announced yesterday that the Public Utility Commission of Texas (PUCT) approved Entergy Texas’ proposal to build two efficient natural gas-fired power plants to support the region’s rapid growth. The combined electric generating capacity of the two facilities, the Legend Power Station and the Lone Star Power Station, will add over 1,200 MW to the Southeast Texas power grid to support new customer demand, increase reliability and lower costs for all customers. Both facilities are scheduled to commence operations by mid-2028.

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.
