Wedoany.com Report-Nov 12,  Constellation Energy has applied to reopen a nuclear power plant on Three Mile Island in the Susquehanna — not the one shut after a coolant failure in 1979, but its long-running neighbor, closed by Exelon Corp. in 2019, as cheaper natural gas made the aging uranium plant too expensive to run.

Constellation, a Baltimore-based electric plant operator spun off by public-utility giant Exelon in 2022, says it wants to bring the plant back by 2028, pending federal approvals, to take advantage of recent U.S. tax credits for non-carbon-generated electricity and to meet demand from Microsoft.

The software giant agreed to buy power from Constellation equal to the plant’s full 835 megawatts — enough to power all 800,000 homes in Philadelphia — for 20 years after the plant’s reopening, to run its growing network of data centers.

Constellation has been inviting public officials, media, energy scholars, and others for limited tours of its mothballed nuclear plant near Middletown, Pa., south of Harrisburg. The company has rechristened the plant as Crane Clean Energy Center after Exelon’s late chief executive and nuclear-power advocate Christopher M. Crane, who died in April at 65.
