LCG, May 8, 2025--The Southwest Power Pool (SPP) Board of Directors approved SPP’s proposed Expedited Resource Adequacy Study (ERAS) at its May 6 meeting. SPP developed the new ERAS in collaboration with its stakeholders in response to the growing need to add new generating resources before the region’s generating capacity is outpaced by its electricity demands. ERAS is intended to be a one-time, expedited study process designed to significantly accelerate the addition of new power generation facilities to the grid and address concerns about the near term ability to maintain the affordable and reliable electric service that consumers expect.

LCG, May 7, 2025--EDP Renewables North America LLC (EDPR NA) announced yesterday the inauguration of its Scarlet II Solar Energy Park (Scarlet II) in Fresno County, California. This phase of the solar plus energy storage project includes 200 MW of solar capacity, plus a co-located 150 MW/600 MWh battery energy storage system (BESS). The initial phase of the project, Scarlet I, which provides 200 MW of solar and 40 MW/160 MWh of BESS, achieved commercial operations in July 2024.

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.
