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.

FERC Okays El Paso Gas Commitment in Arizona

LCG, June 27, 2001--The Federal Energy Regulatory Commission on this morning approved a plan by El Paso Corp. unit El Paso Natural Gas to supply 620 million cubic feet of natural gas per day to fuel two new electric generating plants in Arizona.

The two plants are the 2,210 megawatt Redhawk facility owned by Pinnacle West Capital Corp., parent company for Arizona Public Service Co., and the nearby 1,000 megawatt Arlington Valley power plant owned by Duke Energy Corp.

The Redhawk plant would burn about 410 million cubic feet of gas a day, while the Arlington Valleyplant would need another 210 million cubic feet a day.

Other shippers using the same pipeline expressed concern that the existing pipeline may not have sufficient capacity to support to two power plants and FERC has asked El Paso to provide assurance that they will be protected.

In order to provide gas to the power plants, El Paso will extend its pipeline by 7 miles at a cost of about $8 million.
