(KNZA)--Representatives from Chicago-based Invenergy updated the Brown County Commission Tuesday on the Grain Belt Express transmission line project.

The about 800-mile line will deliver up to 4,000 megawatts of wind-generated power from southwest Kansas to eastern states. The line will go through 14 Kansas counties—including Brown, Doniphan, Marshall and Nemaha.

The company is seeking approval of a road use agreement with the county for construction of the transmission line.

Jason Brown, director of land and community affairs with Invenergy, said the roads would not take the wear and tear that building a wind farm would entail, as they aren’t traveling in with heavy loads such as big wind turbines.

So far, Brown said they have completed right-of-way acquisition for about 69 percent of the route in Kansas and Missouri through voluntary easement agreements. He said they want to negotiate with landowners and not use eminent domain.

The towers that will support the transmission line will be between 130 to 160 feet tall and about a quarter-mile apart.

Brown said the project will be built in phases. He said construction is expected to begin in late 2023 or early 2024, and the transmission line is to be on line by the end of 2025.

Brown said Invenergy is looking at a total investment of $8 billion in Kansas alone.

Under Kansas statute, the high voltage transmission line is exempt from property taxation for a period of 10 years. In lieu of taxes, the company will make a one-time contribution to Brown County of $180,000.

Representatives of Invenergy also meet with the Doniphan County Commission Tuesday
