Federal Government uses UPLAN model to examine price volatility in ERCOT

LCG, October 11, 2022--The U.S. Energy Information Administration, or EIA, released its latest supplement to the Short-Term Energy Outlook (STEO) in the Texas market, assessing various possible scenarios using LCG’s UPLAN NPM model, with a special focus on the effects on wholesale power prices and market conditions.

Michigan Governor Supports Reopening Palisades Nuclear Facility

LCG, September 16, 2022--The Governor of Michigan last week sent a letter to the U.S. Department of Energy (DOE) in support of Holtec International’s application for a federal grant under the Civil Nuclear Credit (CNC) program to save the Palisades Nuclear Facility in Southwest Michigan. The federal grant could result in restarting the baseload, carbon-free, nuclear power plant.

Summer 2021 Resource Adequacy Scenarios- Revised Report

LCG June 11, 2021--LCG Consulting (LCG) has released its analysis of resource adequacy in ERCOT for summer 2021, as we do each spring.

Under expected conditions, in agreement with ERCOT’s expectations, our model shows the ERCOT region will have enough installed generating capacity to serve peak loading condition. ERCOT projects peak load as 77,144 MW with a total resource capacity of 86,862 MW.

However, more challenging conditions are always possible. This summer follows what may have been the most extreme weather event to ever test the modern Texas grid, February’s storm that is described as a 1-in-a-100 event. The state is still reeling from its effects, and electricity market participants are facing much stronger public scrutiny of reliability, as well as new legislation, some still pending resolution.

Resource adequacy analysis for the region is critical during extreme summer loading conditions. Reserves have tightened because of recent retirements. The ERCOT landscape is rapidly evolving, with significant transmission changes and unprecedented growth of renewables, particularly wind.

Beside using the conditions that ERCOT itself expects to model this upcoming summer, LCG chose three other scenarios to model: reduced wind output, increased generator outages, and higher-than-expected load.

Each scenario sheds light on where issues might arise and what magnitude of effects might occur.
