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.

LCG, September 4, 2025--Puget Sound Energy (PSE) announced yesterday that phased construction has commenced on its 142-MW Appaloosa Solar Project, a utility-scale solar facility underway in southeastern Washington. The project is being built by Qcells EPC, who will serve as the module manufacturer and the engineering, procurement, and construction (EPC) solution provider. Construction is scheduled through 2026, and commercial operation is expected at the end of next year.

Analysis of Summer Resource Adequacy in ERCOT
LCG, July 28, 2016--LCG Consulting releases its analysis of resource adequacy in Texas for high stress conditions in summer 2016.
Every year, the Electric Reliability Council of Texas (ERCOT) publishes reports on Seasonal Assessment of Resource Adequacy, or SARA. In it, ERCOT identifies scenarios to determine whether the Texas system can meet demand under a variety of challenging conditions. LCG has modeled these cases and offers an in-depth exploration into what happens with prices, congestion, and generation under the cases ERCOT presents in the 2016 summer assessment.
Using the advanced UPLAN-NPM modeling system, LCG extends ERCOT’s snapshot report of the summer season to delve more fully into system challenges and outcomes associated with such stress cases, including ramping constraints, Operating Reserve Demand Curve (ORDC) outcomes, pricing impacts, and unit commitment requirements.
LCG’s study models dispatch in the ERCOT region at five-minute intervals, instead of the more common hourly simulation. Modeling smaller slices more accurately captures the operation of the ERCOT system, including the sub-hourly ramping constraints of thermal units, which is particularly important under the SARA report stress cases.
The report relies on LCG’s UPLAN sub-hourly modeling capability as well as robust knowledge of all aspects of electricity transmission and generation in Texas, and decades of electricity modeling experience in the state.
