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.

California ISO Goes Ahead with $473 Million Upgrade

LCG, June 26, 2002--The California Independent System Operator has taken a step to remedy a transmission bottleneck on "Path 15."

The ISO approved $437 million to expand Path 15, which connects Northern and Southern California.

Two pre-existing 500 kilovolt lines will be joined by a third in the Central Valley, and major substations will be improved to add 1,500 MW in transmission. The project should be completed in 2004.

The ISO says that the upgrade will yield $100 million a year in savings and up to $300 million in dry years.

Pacific Gas and Electric utility, Trans-Elect Inc., and the Western Area Power Administration will pay for the project, although Trans-Elect will pay the most and therefore receive the larger part of the transmission rights.

The project has yet to be approved by the California Public Utilities Commission.
