The United States has lost yet another nuclear power plant despite the Biden administrations efforts to prevent the countrys largest source of zero-carbon electricity from shrinking any further.

On Friday, the Palisades Nuclear Generating Station, an 800-megawatt reactor plant in southwest Michigan, shut down more than a week early, dashing hopes that a last-ditch appeal by Gov. Gretchen Whitmer (D) for federal funding might prevent the site from going offline.

The plant, with the capacity to power 800,000 homes, safely operated for 50 years on the shores of Lake Michigan. But the facility, like many other U.S. nuclear plants, struggled to make money as cheap natural gas gobbled up its share of the electricity market.

Utility giant Entergy, the plants owner, announced in 2017 it would close the plant by 2022. Last month, Whitmer sent a letter to the Department of Energy formally requesting a share of a $6 billion fund the White House established to bail out financially-troubled but safe-to-operate reactors. Opened in 1971, the plant was licensed to operate through 2031. The plant was scheduled to shut down permanently on May 31.
