Plan Would Power New Microsoft AI Data Center From Pa.'s Three Mile Island 'Unit 1' Nuclear Reactor
upstart writes:
One of the two nuclear reactors at Three Mile Island, the Pennsylvania site of a notorious partial meltdown 45 years ago, could be brought back online in the coming years to provide power to a new Microsoft artificial intelligence data center, officials said Friday.
Constellation Energy, the Baltimore-based provider that spun off Exelon two years ago, has signed a 20-year power purchasing agreement with the tech giant to draw electricity generated at the plant along the Susquehanna River outside Harrisburg and about 85 miles west of Philadelphia.
Pending regulatory approvals, the newly created Crane Clean Energy Center would become the first nuclear plant in the United States to return to service after being shut down.
The $1.6 billion project will restart Three Mile Island Unit 1, which stopped generating power five years ago because it could not compete with cheaper energy being produced by Pennsylvania's natural gas industry. The reactor can be run independently from Unit 2, where the plant's partial meltdown occurred resulting in the worst nuclear accident in U.S. history on March 28, 1979. That reactor is still in the process of being decommissioned by owner Energy Solutions.
"Before it was prematurely shuttered due to poor economics, this plant was among the safest and most reliable nuclear plants on the grid, and we look forward to bringing it back with a new name and a renewed mission to serve as an economic engine for Pennsylvania," Joe Dominguez, president and CEO of Constellation, said in a statement.
[...] In the race to develop artificial intelligence applications, tech companies are scrambling to build data centers, which require enormous amounts of electricity to operate. Such facilities are forecast to make up a growing share of the nation's electricity use in the years to come, prompting companies to look at tapping into existing infrastructure to help meet their needs.
Nuclear power is being touted as a cost-effective solution for these data centers that also limits reliance on carbon-producing power sources. Building and directly connecting data centers to nuclear plants is known as co-location, a strategy that industry leaders favor because it's cheaper and faster to do. Proponents also claim it reduces stress on the transmission grids.
During the years the 837-megawatt unit operated at Three Mile Island, the reactor powered about 830,000 homes and businesses. Constellation officials did not say how much of the reactor's power-producing capacity would be dedicated to powering Microsoft's AI data center, but it's not uncommon for such facilities to have energy demands of 1,000 megawatts - or 1 gigawatt.
An economic impactstudycommissioned by the Pennsylvania Building & Construction Trades Council estimates the restart of Three Mile Island would create 3,400 jobs directly and indirectly related to the plant and generate about $3 billion in state and federal tax revenue.
