Indiana is known as the “Crossroads of America” because several highways intersect in the state. Similarly, electric utilities in Indiana have built several extra high voltage transmission lines, making Indiana an attractive hub for the Grain Belt Express Clean Line to deliver 3,500 megawatts of abundant, affordable, renewable power. We are working with PJM to study interconnection at the 345/765-kilovolt (kV) substation in Sullivan County, Indiana. Below, please find a link to the most recent PJM study reports. Additional study reports will be posted as they become available.
Many electricity consumers in Missouri and Illinois are served by MISO. We are studying interconnection with MISO to examine the impacts of delivering 500 megawatts of power into the existing 345 kilovolt (kV) system in northern Missouri. Below, please find a link to the most recent MISO study reports. Additional study reports will be posted as they become available.

The abundant wind resource area and the western end of the Grain Belt Express Clean Line are within the SPP region. Clean Line has worked closely with SPP, its Transmission Working Group (TWG), and other affected transmission owners since 2012 to conduct studies. In September 2013, the TWG approved Grain Belt Express Clean Line’s reliability studies, completed in accordance with SPP Criteria 3.5, which requires entities requesting transmission interconnections to work with the SPP, the TWG, and affected parties to ensure grid reliability. In March 2015, ITC Great Plains completed the Facility Study of Grain Belt Express’ interconnection facilities. Grain Belt Express will interconnect with the ITC Great Plains system in SPP. We look forward to proceeding with detailed design and final interconnection arrangements.
