The Midcontinent ISO on March 9 announced the third cycle of projects to be evaluated under its Expedited Resource Addition Study (ERAS) process, marking another step toward accelerating the deployment of critical generation resources across the region.
This cycle includes 15 projects totaling approximately 8 gigawatts (GW) of proposed new capacity. The portfolio features a mix of natural gas resources and battery storage spread across MISO’s North, Central and South regions. All projects are expected to be in-service by 2031 or earlier.
“Each ERAS cycle helps advance the resources our system needs to reliably serve a growing region,” said Aubrey Johnson, Vice President of System Planning. “The interest we continue to see reflects both the urgency and the opportunity to develop a clear, timely path to interconnection, and ERAS is helping us provide that in the near term."
Since the program launched, 53 projects representing nearly 27 GW of proposed capacity have been accepted or are pending validation into ERAS. Ten have already advanced to completed generator interconnection agreements, with an additional 15 projects nearing completion. There is a program cap of 68 projects before ERAS sunsets on August 31, 2027.
“ERAS is one piece of a broader strategy to improve the speed and certainty of our generator interconnection queue,” Johnson added. “We’re making steady progress toward a more efficient process for our members and the communities that rely on them.”
To date, MISO has studied more than 11 GW of proposed capacity through its ERAS process.
