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.

Wind Integration - DOE Project Promotes Collaborative Planning for Balancing Wind Variability across Regions



- Integrating SPP Wind Energy into SERC Electricity Markets

LCG, August 6, 2010 -- Department of Energy has awarded Electric Power Research Institute (EPRI) and LCG Consulting (LCG) a contract under the “20% Wind by 2030” challenge to explore innovative solutions for utility wind energy integration.

LCG will provide the key modeling support to analyze the benefits and costs of regional collaboration for integrating the Southwest Power Pool (SPP) wind energy into the Southeastern Electric Reliability Council (SERC) electricity markets.

“… through coordinating balancing operations between SPP and SERC, we expect the study will begin to quantify the value of integrating regional wind and transmission …,” says Sidart Deb, VP of Operations at LCG.

To determine the physical and financial benefit of inter-regional coordination between SPP and SERC, LCG will use the UPLAN Network Power Model and PLATO database to simulate the entire southeast region.

The results of the study shall answer key questions about the overall economics of building wind plants in SPP and sharing output with SERC to accommodate meet the upcoming federal renewable mandates and to control the variability and uncertainty of wind in availability in SPP.
