Our short video describes how America’s electric grid came to be and the solutions we are driving forward – long-haul transmission lines to make our power more reliable and secure.
The North Plains Connector is an approximately 400 mile and up to 500 kilovolt high voltage direct current (HVDC) transmission line connecting the U.S. eastern and western electric grids in Montana and North Dakota. The alternating current portions of the project, which will connect the converter stations on either end of the line to the local grids, will be 345 kV. The North Plains Connector will be open to all sources of electrical power generation. In response to demand, the project will be able to transport power in either direction along the line.
The North Plains Connector is in the planning and development phase. We will continue to gather input from stakeholders and study the proposed project corridor. Using that input, we will finalize our route analysis, purchase land rights, and initiate regulatory filings, with approvals expected in 2026. Construction will commence after the project obtains the necessary regulatory approvals. The North Plains Connector could be operational as early as 2031.
North Plains Connector is currently in the development phase of the project. Incorporating feedback from stakeholders and biological and cultural surveys, we are preparing a proposed route to include in our regulatory filings. In 2023, land agents began presenting landowners with Option for Easement Agreement documents, which will authorize the project the option to secure an easement on a specific portion of participating properties. In Summer 2024, North Plains Connector plans to initiate regulatory filings at the federal, state and county levels. The regulatory process will include a rigorous environmental review pursuant to the federal National Environmental Policy Act as well as state and local review.
