LCG, April 23, 2026--TerraPower announced today the official start of construction on its Kemmerer Unit 1 nuclear power plant, which could be the first utility-scale advanced nuclear power plant in the United States. In early March, the Nuclear Regulatory Commission (NRC) announced that it had authorized the staff to issue a construction permit for Unit 1 commercial nuclear power plant in Kemmerer, Wyoming.

Press Release
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.
About LCG Consulting:
Silicon Valley-based LCG Consulting has been modeling electricity for more than 30 years. In that time, energy market participants and research institutions across the United States and internationally have relied on our models for every type of application, from electricity trading, plant siting, asset valuation, and testimony support.
