The Midwest's large power grid operator plans to release on Sept. 23 the first request for proposals for one of 18 large transmission projects under a just approved $10.3-billion expansion program.
The Midcontinent Independent System Operator, or MISO, board approved the program July 25, with the first projects to be operated by 2028 and the rest by 2030. MISO will make the RFP schedule public on Aug. 24.
