The United States could decide in June on the return to service of Three Mile Island, according to officials

Constellation Energy, one of the world’s largest electricity producers, is hoping that American regulatory authorities will make a decision next month on when the Three Mile Island nuclear plant can restart, company executives said on Monday.

Constellation aims to restart its nuclear plant in Pennsylvania, now called the Crane Clean Energy Center, next year. The company has faced potential delays of several years due to the overall electrical grid and has turned to the Federal Energy Regulatory Commission (FERC) to address this scheduling issue.

Initial indications from the PJM grid suggested that the Crane nuclear plant may not be able to power the grid before 2031.

FERC could rule in June or July on Constellation’s request to transfer some of its electricity injection rights from its Eddystone natural gas plant outside of Philadelphia to the Crane plant, executives said during a quarterly conference call with investors.

“I don’t want anyone to think the plant won’t restart any sooner,” said CEO Joe Dominguez.

Restarting the plant is part of a contract to power Microsoft’s data centers in the region. No fully closed plant has ever been restarted, but three initiatives to restart reactors are currently underway in the U.S. as electricity demand rises due to the growth of energy-intensive data centers and the electrification of industries and buildings.
