Beverly-Sub 92
345 kV Transmission Line Project
345 kV Transmission Line Project
Responding to the needs of the changing energy landscape, the Midcontinent Independent System Operator (MISO), the grid planning organization for our region, has devoted several years of an intensive, collaborative effort to develop a Long-Range Transmission Plan – known as LRTP – to build needed high-voltage transmission infrastructure across the region. ITC was actively involved with this process and advocated for the LRTP projects.
One segment of the LRTP portfolio is the proposed Beverly – Sub 92 project, that travels through Linn, Johnson and Muscatine counties from ITC Midwest’s Beverly Substation in Cedar Rapids (Linn County) to the Sub 92 Substation owned by MidAmerican Energy, which is located near West Liberty in Muscatine County. ITC Midwest will have sole responsibility for the construction, operation and maintenance of this project.
The proposed route includes constructing a new 345,000 volt (345 kV) transmission line that joins the route of an existing 161 kV transmission line which will be removed and rebuilt in a triple circuit configuration (three circuits on the same structures), including a separately proposed 345 kV transmission line for a portion of the route in Linn and Johnson counties. Altogether through the three counties, the line is approximately 49 miles. The final route may change and will be determined when easement negotiations with landowners are completed and the Iowa Utilities Commission has approved the project.
The Beverly – Sub 92 project will provide numerous benefits and drive value for electric consumers locally and regionally. When completed, this transmission line will:
