The Midcontinent ISO on Aug. 26 shared the list of applications submitted to date for the Expedited Resource Addition Study (ERAS), which includes 47 projects across 12 states, representing more than 26,500 megawatts of proposed new capacity.
ERAS is a temporary process aimed at fast-tracking urgently needed generation projects across the region.
The proposed projects include: 74% natural gas, 15% battery storage, 4% wind, 4% solar and 3% nuclear.
“This broad mix underscores MISO’s evolving energy landscape and the urgent need to bring new resources online to address growing reliability challenges,” said Aubrey Johnson, MISO’s vice president of system planning. “These projects are designed to meet localized and accelerating demand growth.”
The ERAS process will study up to 10 projects per quarter, with a maximum of 68 projects before the program sunsets on Aug. 31, 2027. ERAS was developed in close collaboration with stakeholders to address specific load growth and/or resource adequacy concern -- through the Generator Interconnection process, it said.
“ERAS is another tool in our toolbox to help maintain reliability while we continue to improve the interconnection process for the long term,” Johnson continues. “These projects must meet strict requirements to ensure that only viable, needed projects are considered.”
MISO continues to evaluate the applications to ensure all requirements are met and will publish the approved ERAS projects after September 2, 2025.
Eligible projects must demonstrate a clear resource adequacy or reliability need, be commercially operable within three to six years and have support from Relevant Electric Retail Regulatory Authority.
