Adair-Ottumwa Transmission Line


Stated Purpose:

This 71-mile transmission project is “a key reinforcement” for an area experiencing congestion between Iowa and Missouri, according to MidAmerican Energy, which will again split this project with ITC Midwest.  In addition to relieving congestion, the project would enable new wind development along the corridor as well.

As part of the MISO MVP portfolio, these lines will be subject to regional cost allocation. In addition to creating new opportunity for wind development, this transmission projects will also help reduce congestion, improve system reliability, and facilitate wholesale market competition.
