The case against them? The energy crypto miners use puts "an almost unprecedented burden" on the Texas grid, according to Ben Hertz-Shargel, global head of Grid Edge, a unit of Wood Mackenzie, an energy consulting firm. Mining "pushes the system closer to dangerous system peaks at all times," he told NBC News. "It is completely inessential and consuming physical resources, time and money that should be going to decarbonize and strengthen the grid...." Unlike other electricity systems, the Texas grid does not connect to other states' grids; that means it cannot receive power from other areas in emergencies. Because of their high demand for electricity, crypto miners raise costs for other consumers of power, Hertz-Shargel said. And, on the Texas grid, miners can get paid for powering down during peak demand periods, like the one that recently hit the state. Miners and other industrial customers with these types of arrangements receive revenues for not using electricity; the costs of those revenues are passed on to other electricity customers.... During peak periods, miners can also resell to the grid the electricity they would otherwise have used. Because their contracts can let them buy power at low cost, energy resales when demand is high can generate significant financial benefits in the form of credits against future use....
Electricity customers across the state will cover those credits, said Andrew Dessler, professor of atmospheric sciences at Texas A&M University. "Ratepayers in Texas are going to be paying it off a little bit every month for decades," Dessler said. "It angers me so much."
According to a 2020 economic impact report commissioned by the Rockdale Municipal Development District, an entity run by area business people, the facility will deliver an estimated $28.6 million in economic benefits to the community over the next decade. Nearly 200 full-time benefited employees are employed by the operation.
