Plattsburgh, New York, is considering a 12-month moratorium on approvals for new or expanded cryptocurrency mining, artificial-intelligence, cloud-computing and other high-energy computing facilities while it updates zoning rules. Local Law P-2, introduced by Mayor Wendell Hughes on Aug. 20 and discussed at a Sept. 3 public hearing, would cover commercial operations primarily devoted to specified computing uses that require High Density Load Service or have connected electrical demand of at least 300 kilowatts. Existing lawful facilities could continue operating and perform routine maintenance, but expansions requiring municipal approval would be prohibited. The proposal would suspend building, zoning and special-use permits, site-plan approvals and certificates of occupancy for covered projects, including conversions and reopenings. Hughes said some data-center proposals can require about 50 megawatts, against Plattsburgh's approximately 105 MW power allocation. The ordinance has not been adopted and requires county review, environmental compliance and a Common Council vote before taking effect. No publicly traded miner or data-center operator has disclosed a material project affected by the proposal, and the council's next regular meeting is scheduled for Sept. 17.
