ACP Statement on FERC Approval of MISO and SPP ERAS Proposals
Jul 23 2025
WASHINGTON, D.C. July 23, 2025— The American Clean Power Association (ACP) released the following statement from ACP Vice President of Markets & Transmission Carrie Zalewski after the Federal Energy Regulatory Commission’s (FERC) approval of the Midcontinent Independent System Operator (MISO) and Southwest Power Pool’s proposed Expedited Resource Addition Study (ERAS) proposals:
“FERC’s approval of MISO and SPP’s ERAS proposals is a dangerous misstep, ignoring widely acknowledged market realities while signing off on the potential for major disruption for projects that have gone through the proper processes to be connected to the grid. The fastest growing sources of energy—solar, wind, and energy storage technologies—are the ones ready to deploy to help keep costs lower and power reliable for the more than 60 million American consumers served across both territories.
“Maintaining reliable and affordable power requires a diversified grid and predictable measures to bring new resources online. We are committed to advancing this shared goal and responsibility in a way that instills confidence and benefits consumers and will work with stakeholders in SPP and MISO to ensure these approved requests do not set a precedent that will cause lasting damage.”
The Facts
States with higher deployment of clean energy see increases in reliability, as well as lower electricity prices on average.
-
- During the Polar Vortex of 2025, where temperatures plummeted across the country, Texas and California only experienced a 20% increase in prices while states in MISO experienced an eye-popping 135+% increase in prices (Jan. 19-23, 2025).
- In SPP, during an intense heatwave in Summer 2024, wind rose to 30% of total demand during the heatwave, helping reduce operating costs by at least $27M (July 13-17, 2024).
