Oneida–Sabine Lake

Project Background

Responding to the needs of the changing energy landscape, the Midcontinent Independent System Operator (MISO), the grid planning organization that includes Michigan, has devoted several years of an intensive, collaborative effort to develop a Long-Range Transmission Plan (LRTP) to build needed high-voltage transmission infrastructure across the region. ITC was actively involved with this process and advocated for the LRTP projects.

In December 2024, the MISO Board of Directors unanimously approved the largest portfolio of transmission projects in the nation’s history. This includes LRTP Tranche 2.1 – 24 projects totaling 3,631 miles for regional projects in MISO’s Midwest subregion (Illinois, Indiana, Iowa, Michigan, Minnesota, Missouri, North Dakota, South Dakota and Wisconsin) and includes a 765kV backbone.

Oneida to Sabine Lake

Oneida to Sabine Lake will involve constructing approximately 50 miles of 345 kV lines from the existing Oneida station in Eaton County to a new Sabine Lake station in Livingston County.

These projects are critical to maintaining reliable and economic delivery of energy that increases resiliency, improves reliability, and delivers widespread economic benefits.

About ITC

ITC, through its subsidiaries ITCTransmission and Michigan Electric Transmission Company, LLC (METC), owns and maintains more than 9,100 circuit miles of high-voltage electric lines and 397 transmission substations throughout Michigan’s Lower Peninsula. METC will build and maintain the Oneida-Sabine Lake Project

FAQ

Who is MISO?

As an independent, non-profit Regional Transmission Organization (RTO), the Midcontinent Independent System Operator (MISO) acts as an “air traffic controller” for the regional grid with the mission of working collaboratively with electricity stakeholders across 15 US states and Manitoba. Forty-five million people depend on MISO to generate and transmit the right amount of electricity every minute of every day – reliably, dependably and cost-effectively.

What is LRTP or Long Range
Transmission Planning?

The Midcontinent Independent System Operator (MISO) initiated a collaborative and innovative effort, known as Long Range Transmission Planning (LRTP), to provide a roadmap for future transmission investment across the MISO region.

MISO’s LRTP is a group of four planned phases, or tranches, with Tranche 2.1 representing a $21.8 billion investment of 24 transmission projects in MISO’s Midwest Subregion and includes projects in Michigan. Overall, the LRTP projects are the largest portfolio of long-range transmission projects in RTO history, providing a roadmap for future transmission investment across the MISO footprint.
