SPP Board Approves Alternative, Accelerated Generation Interconnection Process to Improve Regional Resource Adequacy

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.

EDP Renewables Completes Scarlet II Solar and Energy Storage Project in California

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 Approves PJM Proposals to Accelerate New Generation Projects

LCG, February 19, 2025--The Federal Energy Regulatory Commission (FERC) last week approved two PJM proposals to improve the approval process and accelerate the construction of new power generation assets, with the ultimate objective of providing sufficient, reliable electricity supplies to customers.

On December 13, 2024, PJM filed revisions to the Reliability Resource Initiative (RRI) to add provisions enabling a one-time reliability based expansion of the eligibility criteria for Transition Cycle #2 of PJM's existing interconnection queue. The RRI modifications are designed to add up to 50 additional projects to be studied in Transition Cycle #2 to address near-term resource adequacy concerns in PJM.

FERC's findings included stating PJM's proposed RRI revisions are just and reasonable, and that they address the possibility of a resource adequacy shortfall driven by significant load growth, premature generation retirements, and delayed new capacity additions.

FERC's second approval was of PJM's December 20, 2024 filing to revise governing surplus interconnection service and to facilitate the rapid expansion of existing and planned generating facilities. FERC accepted PJM's proposed revisions, effective March 7, 2025, as requested by PJM.

In the second filing, FERC found PJM's revisions are just and reasonable. FERC findings include that the revisions will facilitate the use of existing surplus interconnection capacity by (i) removing certain limitations in the PJM Tariff and (ii) making surplus interconnection capacity available sooner in the interconnection process. The revisions will help address PJM's stated near-term reliability needs and increase the overall efficiency of PJM's interconnection queue.

In PJM's Long-Term Load Forecast Report released in January, the PJM RTO annual summer peak load growth and winter peak load growth over the next 10 years are projected to average 3.1% and 3.8%, respectively. The projected annual net energy average load growth is 4.8%. The PJM RTO winter peak load in 2034/35 is forecast to be 198,175 MW, a 10-year increase of 62,048 MW, which equates to adding more than 6,000 MW per year.
