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.

FERC Issues Preliminary Permit for 1,200-MW Southeast Oklahoma Pumped Storage Hydroelectric Project
LCG, March 5, 2019--The Federal Energy Regulatory Commission (FERC) issued a preliminary permit to Southeast Oklahoma Power Corporation to study the feasibility of the proposed Southeast Oklahoma Pumped Storage Hydroelectric Project. The electric generating capacity of the proposed energy storage facility would be 1,200 MW. The project site is located on the Kiamichi River near the town of Whitesboro in LeFlore County, Oklahoma. The project includes a 124-mile-long transmission line to connect to the Electric Reliability Council of Texas (ERCOT) grid.
The purpose of a preliminary permit is to study the feasibility of the project, including studying potential impacts. The permit was effective March 1, 2019.
The Southeast Oklahoma Pumped Storage Hydroelectric Project is intended to provide utility-scaled energy storage capabilities to complement the growth of wind farms that intermittently generate electricity within the day throughout the year. The project will pump water from the lower reservoir to the upper reservoir at times when power prices are relatively low. When power prices are high and energy is needed, water will be released from the upper reservoir through the power tunnel to the powerhouse to generate electricity. This will occur based on hourly power prices, the need to augment the production of local renewable wind power generation, or to provide ancillary power services.
To move the water between the reservoirs, the project design includes four reversible pump-turbine units with a combined electric generating capacity of 1,200 MW. The proposed upper reservoir will have a surface area of 488.52 acres and a storage capacity of 43,633 acre-feet; the lower reservoir will have a surface area of 727 acres and a storage capacity of 37,965 acre-feet. A regulating reservoir will be included, with a surface area of 40 acres and a storage capacity of 1,216 acre-feet. The proposed project has an estimated average annual generation of over 4,300,000 MWh.
