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.

Alabama PSC Approves Mix of Natural Gas Resource Additions for Southern Company
LCG, June 12, 2020--The Alabama Public Service Commission (PSC) voted unanimously on Tuesday to authorize Southern Company to buy, build or contract for nearly 2 GW of natural gas resources to meet resiliency needs.
Alabama Power, a Southern Company subsidiary, had previously announced that it will switch from a summer-peaking to a winter-peaking system. It had also proposed new solar installations, energy efficiency, as well as natural gas additions.
Alabama Power‘s proposed gas expansion plan includes (i) the purchase of an Autauga County gas-fired power plant with a 915 MW winter capacity, (ii) the installation of 726-MW combined cycle facility at the Barry Electric Generating Plant, and (iii) completion of a power purchase agreement (PPA) in 2020 for the entire capacity of the combined cycle Hog Bayou Energy Center, which has a winter capacity of 238 MW and is located in Mobile. The new energy facility at the Barry Steam Plant (which currently includes both coal-fired and natural gas-fired units) is expected to be on-line in November 2023.
The PSC approved 200 MW of programs to increase energy efficiency and mitigate peak energy usage. The PSC did not approve five proposed solar facilities with battery storage, which would have totaled 400 MW. These resource additions are expected to be considered in a separate docket focused on procurements. The PSC still must issue a final order on the resiliency plan.
