On 28 March, 1979, a combination of mechanical failure and human error led to a partial meltdown at the nuclear power plant in central Pennsylvania.
The accident occurred about 04:00 in the Three Mile Island plant’s second unit.
The plant’s Unit 1 – which would reopen under the Microsoft deal – continued to generate power until closing in 2019.
Its owner at the time, Exelon, which spun out Constellation as an independent business in 2022, said the low cost of natural gas extraction had made nuclear-generated electricity unprofitable.
Constellation said it would invest $1.6bn (£1.2bn) to upgrade the facility, which it would seek approval to operate through 2054.
Reopening the plant would create 3,400 direct and indirect jobs and add more than 800 megawatts of carbon-free electricity to the grid, generating billions of dollars in taxes and other economic activity, according to a study by The Brattle Group cited by Constellation.
Local media reported earlier this month that word of its possible revival had drawn some protesters, external.
Microsoft is not the only tech company that is turning to nuclear power as its energy needs expand.
Earlier this year, Amazon also signed a deal which involves purchasing nuclear energy to power a data centre. Those plans are now under scrutiny by regulators.
