North Rochester-Hampton 345 kV
Overview
Xcel Energy, Dairyland Power Cooperative, Southern Minnesota Municipal Power Agency, and the City of Rochester have partnered to construct, own, and maintain the proposed North Rochester to Hampton 345 kV project, which would add a second circuit to the existing Hampton-Rochester transmission line built as part of the CapX2020 project. This project is a part of the Midcontinent Independent System Operator's (MISO) Long-Range Transmission Planning (LRTP) Tranche 2.1 portfolio, a regional effort to modernize the electric grid and meet growing energy needs.
