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.

PG&E Executes Agreement for Solar Power from 177-MW Thermal Plant

LCG, November 6, 2007--Pacific Gas and Electric Company (PG&E) yesterday announced a power purchase agreement with Ausra, Inc. for the electric output from a 177-MW solar thermal power project proposed in central California in San Luis Obispo County. The project is planned to be operational in 2010.

The project will incorporate Ausra's Compact Linear Fresnel Reflector (CLFR) solar technology designed to use the sun's energy to boil water at high temperatures to power steam turbine generators, similar to traditional fossil-fuel power plants - but without air or water emissions. According to Ausra, a CLFR collector reflects and concentrates sunlight on an elevated absorber to roughly 30 times the intensity of sunshine at the earth?s surface.

The solar collector footprint for the project will require about one square mile (640 acres) of land. Ausra filed an Application for Certification for this plant with the California Energy Commission, from which approval is required prior to construction.

California passed a Renewable Portfolio Standard (RPS) Program that requires utilities to increase their electric supply procurement of eligible renewable generating resources by one percent of load per year, with a 20 percent renewables target by the end of 2010 and a 33 percent target by the end of 2020.

Ausra is a privately held, California-based company funded by Khosla Ventures and Kleiner, Perkins, Caufield & Byers.
