US Midwest grid operator accelerates review of 15 power supply projects

Midcontinent Independent System Operator, the U.S. Midwest grid operators, will speed up reviews of 15 additional power projects in order to add electricity faster. This is part of a legal challenge from environmental and consumer groups.

The country's largest regional grids – MISO, Southwest Power Pool, and PJM Interconnection – have approved dozens power projects for a speedy review this year as operators raise the alarm about the rising demand that is outpacing new electricity sources.

Some of these fast-tracking procedures have been challenged in court on the grounds that grid operators favor natural gas-fired projects over renewable energies, like solar and wind. Natural Resources Defense Council, Sierra Club and other groups have sued the U.S. Federal Energy Regulatory Commission for MISO and SPP programs that require FERC approval.

MISO has announced that the second round of projects selected by MISO includes seven gas-fired power plants, three storage battery projects, three solar energy projects, and two wind turbines. The fast-track project is designed to reduce the time required to connect power supplies to grid by months or even years.

MISO Vice-President Aubrey Johnson said, "These projects are crucial to meeting near term reliability needs and to ensuring that new resource additions come online to meet the load growth."

The 15 projects have a total capacity of more than 6 gigawatts and their start-up dates range between December 2027 and August 2028. One gigawatt is enough to power 750,000 homes.
