Indiana Michigan Power Plans Transmission Line Talks
Residents near proposed 765-kilovolt routes can now book one-on-one meetings with the utility's project teams.
Updated on Nov. 9, 2026 in Utilities
Indiana Michigan Power scheduled one-on-one meetings with residents near potential routes for two new 765-kilovolt transmission lines, held during the week of November 9. Residents can choose a meeting time, date, and location through the project websites, and no final routes have been selected yet.
Why it matters
The projects are part of MISO's Long Range Transmission Planning Tranche 2.1 portfolio, which MISO identified as necessary to support long-term electric reliability and grid performance across the region. For Indiana residents, the lines will affect which properties and communities are considered for routing.
The Greentown-Sorenson line covers approximately 50 miles and the Lulu-Sorenson line approximately 75 miles, both carrying 765-kilovolt capacity. Final routing for both remains undetermined.
The players
Indiana Michigan Power
Indiana Michigan Power is the electric utility serving northeastern and east-central Indiana, selected by MISO to build these transmission lines.
MISO
The Midcontinent Independent System Operator is a regional grid operator that coordinates electricity transmission across a multi-state region and oversees long-range transmission planning.
The details
Indiana Michigan Power held a Community Connect call last week and is now scheduling individual conversations for residents near potential routes. The Greentown-Sorenson project would run between the Greentown Substation in Howard County and the Sorenson Substation in Huntington County, while the Lulu-Sorenson project would connect to the Indiana-Michigan state line. Project teams are reviewing study segments and community feedback before identifying proposed final routes.
Timeline
Week of November 9, 2026: One-on-one resident meetings on proposed routes
End of 2026: Anticipated decision on the Greentown-Sorenson project
Late February 2027: Expected proposed route for the Lulu-Sorenson project
Roadmap
The two lines are part of MISO's Long Range Transmission Planning Tranche 2.1, a regional buildout designed to strengthen grid reliability across the Midwest. Indiana Michigan Power was selected by MISO to construct both segments within that portfolio.
Residents living near the potential corridors across Howard, Grant, Miami, Wabash, Wells, and Allen counties may see their properties considered for line routing. Booking a one-on-one meeting through the project websites is the direct way to raise concerns before routes are finalized.
The takeaway
Residents affected by the Greentown-Sorenson and Lulu-Sorenson corridors can register for individual meetings now, before routes are chosen. The next concrete milestones are the end-of-2026 Greentown-Sorenson decision and the late-February 2027 Lulu-Sorenson proposal.
What happens next
The Greentown-Sorenson project decision is anticipated by the end of 2026, and a proposed Lulu-Sorenson route is expected in late February 2027.
