Montana will receive $700 million to advance the nation鈥檚 first transmission project bridging the eastern and western grids, a step described as critical to U.S. energy reliability.
The U.S. Department of Energy grant, announced Tuesday by Gov. Greg Gianforte in a press release, will advance the North Plains Connector, a 415-mile, high voltage, direct-current line between Montana鈥檚 Colstrip substation and Center, North Dakota. The 525-kilovolt line could be the first high-voltage line in the country bridging the eastern and western energy grids, allowing power to move from Portland to Minnesota while connecting energy markets serving more than 20 states.
The North Plains Connector is a $3.6 billion project. Several utilities along the transmission route, including NorthWestern Energy, thanked DOE in a letter for investing in a project that should increase energy reliability across multiple states.
鈥淣orthWestern Energy worked collaboratively with Grid United and the Montana Department of Commerce on the application process for the consortium for the Grid Resilience and Innovation Partnership program grant, which also includes a potential upgrade of the Colstrip Transmission System,鈥 said Jo Dee Black, a NorthWestern spokesperson. 鈥淲e are very pleased to learn of the DOE grant for the North Plains Connector Innovation Consortium project, which will reduce the cost of the project and ultimately help reduce costs for customers.鈥
Among the utilities signing the letter was Portland General Electric, a 40-year investor in Montana energy that owns a share of the Colstrip power plant and Montana鈥檚 largest wind farm, the 770 MW Clearwater Wind project in southeast Montana.
Portland General Electric in May said it would use the connector to balance the ebb and flow of its renewable energy supply. The utility will exit Colstrip no later than 2030 to comply with climate-change law in Oregon.
Portland General Electric reserved a 20% capacity share in the North Plains Connector this spring.
The North Plains Connector is being developed by Grid United and Minnesota energy company Allete, which has a 35% development share in the project.
Grid United told 吃瓜黑料 it will apply for federal environmental review this fall and begin facility siting work in Montana and North Dakota.
鈥淎ccess to a steady supply of affordable and reliable energy is critical for communities across Montana and the United States,鈥 Gianforte said in a press release. 鈥淭hrough this investment, we鈥檙e upgrading and modernizing Montana鈥檚 electrical transmission infrastructure to power our homes, schools, and businesses.鈥

Where electricity transmission and the energy transition meet
Project developers, policymakers and think tanks working in the capital-intensive arena of energy development say a new Montana-North Dakota high-voltage transmission line could be a game changer for an area of the American West that鈥檚 seen limited expansion to its power grid in four decades. The North Plains Connector Line would be the region鈥檚 first major grid expansion since the construction of a 500-kilovolt line that carries power from the Colstrip coal-fired power plant to population centers in the Pacific Northwest in the early 1980s.
In addition to the $700 million grant, Montana has received $46 million to spend on roads, sewer and water services along the transmission route to support the North Plains workforce during construction. The money flows from the 2021 Infrastructure Investment and Jobs Act.
鈥淭his project will create good-paying jobs in Eastern Montana, protect our energy grid from natural disaster, and expand our energy portfolio to lower energy costs for Montanans and ensure our economy remains competitive against foreign adversaries like China,鈥 U.S. Sen Jon Tester said in a press release. 鈥淚鈥檓 proud to have secured this funding, and I will keep working to ensure this project is completed effectively and efficiently.鈥
Tester, a Democrat, was the only member of Montana鈥檚 delegation to vote for the infrastructure bill, which over 10 years will spend $1.2 trillion on infrastructure.
The North Plains Connector is already several years into development. It was identified early on as a potential route to reach new markets for coal power produced by the Colstrip power plant. Greenhouse gas regulations in Oregon and Washington are closing energy markets that currently represent 70% of the power plant鈥檚 1480 megawatts of generating capacity.
