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.

Reliant Takes 824 Megawatts of Capacity Offline

LCG-Nov. 5, 2003--After receiving no bids for one year's output from three generating plants it owns in California, Reliant Energy has announced it will mothball 824 megawatts of capacity.

The output of Etiwanda units 3 and 4 near Rancho Cucamonga, Mandalay unit 3 near Oxnard, and Ellwood, near Goleta, was offered at a minimum bid level of the company's cash costs. Because no bids were received, a decision was made to mothball the Southern California units until March 2005. On October 13, Reliant announced a decision to retire Etiwanda units 1 and 2, after seeking similar bids. The costs that it was seeking to cover included required environmental upgrades and forecast operating and maintenance costs of the units.

The auction was conducted as indicated in a settlement with the Federal Energy Regulatory Commission (FERC), announced in October. Reliant Energy plans to offer the capacity a second time in September 2004, and may start the units if bids at or above the projected cash costs are received.

Although Reliant submitted an offer in July to the California Independent System Operator (CAISO) for the Etiwanda units, which represent a total of 640 megawatts, to operate as reliability-must-run (RMR) units, they were not selected.
