Bitcoin mines backlash

Bitcoin "miners" who use rows of computers whirring at the same time to produce virtual currencies began taking root along New York's northern border a couple of years ago to tap into some of the nation's cheapest hydroelectric power, offering an air of Silicon Valley sophistication to this often-snowy region.

But as the once-high-flying bitcoin market has waned, so too has the enthusiasm for bitcoin miners. Mining operations with stacks of servers suck up so much electricity that they are in some cases causing power rates to spike for ordinary customers.

"We don't want someone coming in, taking our resources, not creating the jobs they professed to create and then disappear," said Tim Currier, mayor of Massena, a village just south of the Canadian border, where bitcoin operator Coinmint recently announced plans to use the old aluminum plant site for a mining operation that would require 400 megawatts — roughly enough to power 300,000 homes at once.

In Plattsburgh, where two cryptocurrency operations have been blamed for spiking electricity rates, the prospect of more cryptocurrency miners plugging in spooked officials enough in March to enact an 18-month moratorium on new operations. The small border village of Rouses Point also is holding off on approving new server farms and Lake Placid is considering a moratorium.

For officials, the power struggle has been a crash course in the esoteric bitcoin mining business in which miners earn bitcoins by making complex calculations that verify transactions on the digital currency's public ledger.

Along the stretch of New York near the Canadian border, cheap hydro power from a dam spanning the St. Lawrence River is doled out by a state authority to local businesses that promise to create jobs. Additionally, some municipalities such as Massena and Plattsburgh receive cheap electricity from a separate hydro project near Niagara Falls.

In Plattsburgh, electricity is so cheap most residents use it instead of oil or wood to heat their homes. The couple of commercial cryptocurrency mines here can get an industrial rate of about 3 cents per kilowatt hour — less than half the national average.

But Plattsburgh Mayor Colin Read said its largest operator, Coinmint, which has two plants employing 20 or fewer people, can consume about 10 per cent of Plattsburgh's 104 megawatt cheap electricity quota. When the city exceeded its allocation like it did this winter, customers ended up paying $10 to $30 more a month for the extra electricity. For a major employer like Mold-Rite Plastics plant, it cost them at least $15,000 in February.

State regulators have since given municipal utilities the ability to charge higher rates to cryptocurrency miners. At least one bitcoin miner in Plattsburgh says he's working with the city on solutions to the power worries.

Ryan Brienza, founder and CEO of the hosting company Zafra, said those could include mining on behalf of the city for an hour a day or harnessing the heat from mining computers to warm up large spaces.

Coinmint's plans for a new plant in Massena come with a promise of 150 jobs. That's welcome in an area that in the past decade has suffered though the loss of aluminum-making jobs and the closure of a General Motors powertrain plant.
