FERC approved an SPP tariff revision designed to accelerate the addition of new generation by quickly adding shovel-ready incremental capacity at existing generating sites.

A new report examines CAISO, MISO, PJM and SPP efforts to accelerate interconnection and concludes that while some may succeed in speeding generation additions, some sacrifice fairness, transparency and open-access principles.

SPP said it expects as a “high likelihood” of meeting demand during the upcoming winter season and that it will be prepared in case of an unexpected event.

Environmental groups are further pressing their opposition to MISO's and SPP’s fast-track studies for primarily fossil fuel projects, challenging both at the D.C. Circuit in a pair of lawsuits.

The Sierra Club and Natural Resources Defense Council filed a petition with an appeals court to toss two recent FERC orders that granted SPP’s request to modify provisions for clean energy resources’ capacity accreditation.

SPP says the development of its Markets+ day-ahead market in the West is proceeding on time and under budget, with the hard part yet to come.

SPP state regulators have approved several motions related to FERC Order 1920’s mandate for long-term, scenario-based planning to ensure the system can meet future needs and be fairly compensated.

SPP’s Board of Directors has awarded its eighth competitive project and third in 2025 under FERC Order 1000, a 345-kV upgrade in the Texas Panhandle.

The SPP board has approved the RTO's 2025 Integrated Transmission Plan that includes four 765-kV projects.

A group of nonprofits suing BPA said its decision to join SPP’s Markets+ instead of CAISO’s EDAM “violated clear mandates from Congress.”
