Gorham, NH Tesla Supercharger site to shut October 25 over power bills

Terry MacGillivray, president of Summer Fun Inc., plans to shut down the four Tesla Superchargers at Summer Fun's property at 443 Main Street in Gorham, New Hampshire on October 25, 2026, the Concord Monitor reported on August 23, in a story republished August 29 by New Hampshire Public Radio. The chargers, installed in May at a cost of $407,000 under Tesla's Supercharger for Business program, have produced net revenue of almost $15,900 through mid-August at a 69-cent-per-kWh charging rate, against electric bills that have topped $32,500.

The expensive part is the wires, not the electrons. MacGillivray told the Monitor his July Eversource bill was $13,211.73, of which $10,679.64 was delivery charges, and demand charges keyed to the month's single highest usage spike compound the problem when several cars charge at once. He also missed out on EV-2, a temporary discounted rate for EV chargers that Eversource dropped in 2026; even with that rate he would barely break even, he said. Demand has been there: more than 1,200 vehicles have charged since the site opened, almost half of them non-Teslas, at what the Monitor describes as the only Tesla Superchargers north of the White Mountains.

The shutdown lands on awkward timing for the state. August 21 was the application deadline for New Hampshire's next round of National Electric Vehicle Infrastructure funding, roughly $17.2 million to build DC fast charging along major highways, and selected builders must put up 20 percent of the cost themselves. "Who is going to spend 20% of their own money on infrastructure if they're going to lose money by turning it on?" MacGillivray said.
