ACP Statement: MISO’s Proposal Threatens Reliability and Affordability for Millions of Americans

Press Release

Apr 7 2025

WASHINGTON, D.C. April 7, 2025 —The American Clean Power Association (ACP) released the following statement from ACP Vice President of Markets & Transmission Carrie Zalewski related to ACP’s protest to the Federal Energy Regulatory Commission (FERC), opposing the Midcontinent Independent System Operator’s (MISO) proposed Expedited Resource Addition Study (ERAS):  

“At a time of skyrocketing energy demand, MISO is headed down a concerning path of sidelining critical resources rather than diversifying its generation mix—a grid 45 million Americans rely on to be increasingly reliable and affordable. This proposal sets a dangerous precedent that could cause significant and lasting damage, injecting massive disruption to MISO’s already overburdened queue process. 

“MISO must prioritize solutions that can swiftly address reliability needs — not burden consumers with expensive and unreliable outcomes. ACP urges FERC to reject the ERAS proposal.” 

MISO ERAS is not a one-time emergency request, and lacks guardrails on timing, scope, and implementation. 

  • The proposal does not address resolutions for existing concerns regarding systemic issues causing interconnection delays and readiness constraints, such as permitting, supply chain issues, and financing. 
  • Further, MISO has not accounted for potential cost shifts to projects already in the queue, and in addition, has not demonstrated its ability to adequately implement the mechanism without shifting significant internal resources.   
  • With a 15-state footprint, MISO’s proposed mechanism for accelerated interconnection would harm customers in the existing interconnection queue, create unfair grid access by excluding independent power producers, hinder competition, and increase costs for consumers.  
  • MISO does not use objective metrics tied to its own stated resource adequacy concerns to select eligible projects and makes no attempt to limit the size of the program or penalize speculative projects to limit impacts to the existing queue.
