The 675-megawatt Somerset plant north of Buffalo hasn’t produced power since March 13 and will officially retire Tuesday, according to an emailed statement. Its sister plant north of Ithaca was closed in October and their owner has proposed turning them into data centers.
The closing is no surprise after New York adopted emissions rules in May that would have required the facilities to invest in costly upgrades. And in June the state passed one of the country’s most aggressive climate laws, mandating the use of only carbon-free electricity by 2040.
“The plant has generated electricity for the final time,” plant manager Brian Gregson said in an emailed statement.
