DOT proposes leasing highway and rail corridors for power lines to cut household electricity costs

On Aug. 26 the Department of Transportation introduced America’s Great Corridors of Commerce, a scheme to combine the nation’s 161,000 miles of highways and 140,000 miles of freight rail with transmission, fiber-optic and other critical infrastructure. Under the proposal, state transportation agencies and railroads would award long-term concessions—typically 30 to 50 years—to private corridor managers who would build, finance and operate utility tunnels or above-ground lines, sharing lease revenue with right-of-way owners.

The DOT says the approach could lower residential electricity rates by avoiding piecemeal grid upgrades and generating lease income for transportation projects at no extra taxpayer cost. The agency’s request for information, posted Aug. 18, invites comments until Sept. 12 and outlines possible financing through federal loan programs such as TIFIA and RRIF, as well as potential EPA or DOE support. While the plan does not guarantee bill reductions, it seeks to attract data centers and manufacturers with "plug-and-play" connections and streamline permitting through categorical exclusions. The Association of American Railroads is reviewing the initiative, and the DOT expects to select up to five corridors in the first round.
