Teton County Denies Midway Substation Permit

DRIGGS — The Teton County Board of County Commissioners voted 2-1 on Monday to deny Fall River Electric Cooperative's application for a special use permit to build the Midway Substation, a new electrical substation between Driggs and Victor. The cooperative argued the valley's growth rate, roughly 2.3 percent per year, requires new infrastructure to prevent outages. The commission disagreed.

The vote followed months of public opposition and a recommendation for denial from the Planning and Zoning Commission in November. Dozens of opponents packed the hearing and flooded the Zoom call, many logging in under names like "Deny Fall River," "Deny Substation," and "Deny Midway Substation."

Commissioner Powers cited specific provisions of the Land Development Code in his motion to deny. His stated findings: the proposed substation is incompatible with adjacent residential uses in terms of operating characteristics, and the adverse impacts on the surrounding neighborhood cannot be mitigated. Commissioner Ron James seconded the motion.

Commissioner Brad Wolfe cast the lone dissenting vote. Wolfe said he was "very moved" by public testimony against the substation and acknowledged that noise, visual impact, and lost property values are real costs to neighbors. His objection was procedural: "You can find uses in the code to go both ways," Wolfe said, adding that he wasn't sure the denial rested on solid legal footing.

That concern could matter if Fall River challenges the decision. The cooperative has invested over two decades of planning into the Midway Substation project and secured the five-acre parcel on 3500 South, adjacent to Bonneville Power Administration transmission lines, in July 2025.

Fall River's case centered on necessity. The cooperative told commissioners it has set record energy sales and record system peaks for most months in Teton County, and that new infrastructure is essential to keep the lights on as the county keeps growing.

Neighbors organized against the project through P&Z hearings in October and November. Residents raised concerns about noise, electromagnetic fields, wildlife impacts in a designated big game migration corridor, and falling property values in what is zoned as a rural neighborhood.

The P&Z Commission recommended denial in November on three grounds: inadequate wildlife mitigation studies, missing electromagnetic field data, and insufficient buffering and screening for properties within 1,000 feet. Fall River responded with new EMF and noise studies, an updated landscaping plan proposing 57 trees and 91 shrubs, and a revised construction narrative. The county commission majority found the mitigation still fell short.

All three commissioners acknowledged the valley needs electrical infrastructure. James put it plainly: "It seems like a bad place to put a substation." Powers said the public benefit of reliable power was real, but so was the cost to residents in property values and noise, and that Fall River had not demonstrated how to offset those harms.

The staff report and application materials are available through the Teton County Planning and Zoning office.
