PUC of Texas Approves Entergy Texas' Plans to Build Over 1,200 MW of Gas-Fired Capacity

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.

Luminant Allowed to Mothball Nearly 1,200 MW of Coal-fired Generation in Texas

LCG, November 1, 2012--The Electric Reliability Council of Texas (ERCOT) approved Luminant's proposal to mothball two coal-fired electric generating units at the Monticello Power Plant, located in northeastern Texas. ERCOT concluded the two units will not be necessary to ensure grid reliability through the upcoming winter and spring.

Luminant will mothball Monticello 1 and 2 commencing on December 1 for six to seven months. The capacity of each unit is 583 MW; Monticello 3, with a capacity of 763 MW, will remain available to produce power. The plant burns lignite, supplemented by Powder River Basin coal.

The units are approaching their 40-year anniversaries; Units 1, 2, and 3 commenced operations in 1974, 1975, and 1978, respectively.

According to Luminant, wholesale power prices are too low to support the costs required to keep the units available and to generate power.

In order to maintain reliable power resources, Texas regulators are taking some action to encourage new generation to be built and/or to defer retirement of existing generation. Last Thursday, the Texas Public Utility Commission voted to increase the price cap on wholesale electricity from $4,500/MWh, starting in June 2013. Initially, the cap will increase to $5,000/MWh, with subsequent annual increases reaching $9,000/MWh on June 1, 2015.
