The Grid North Partner utilities, which includes Dairyland Power Cooperative, welcome the Midcontinent ISO’s (MISO) approval of the first set of projects in its Long Range Transmission Plan to pave the way for new transmission lines to serve customers throughout the Midwest, including several projects in the Grid North Partners’ footprint, which will deliver considerable benefits to Upper Midwest electric customers.
“The Upper Midwest region leads the country in renewable energy, and as our system transitions away from fossil fuel plants, we need new transmission infrastructure to help ensure reliability and resilience, deliver carbon-free energy, and keep bills affordable for our customers,” Grid North Partners said in a joint statement. “We stand ready to develop these new projects.”
The 345-kV transmission projects approved today will provide greater access to renewable energy over a wide geographic area and save costs by locating new transmission lines near or along existing transmission or other infrastructure corridors reducing impacts to landowners by sharing rights-of-way.
All projects will still require approval from state regulatory agencies. Lead utilities will also engage landowners, local governments and other stakeholders as part of the project-development process.
Grid North Partners key part of regional planning process
Grid North Partner utilities participated in the MISO-led effort that identified and evaluated a comprehensive ‘transmission roadmap’ for the region as the energy system evolves towards more carbon-free energy produced from more variable, weather-dependent renewable resources.
The phase-one plan MISO’s Board of Directors approved today is the result of nearly two years of study, engagement and outreach with utilities and various stakeholders. Additional phases of future transmission projects throughout the northern MISO region will be considered in coming years. Information about MISO’s LRTP can be found on MISO’s website here.
