Damaged power lines and homes after Hurricane Delta made landfall in Holly Beach, Louisiana, in Oct., 2020.

The U.S. power grid is becoming less resilient and reliable, with extreme weather leaving more Americans without electricity more often over the past several years, analysts for Fitch Ratings said. 

Weather accounted for 25% of utility company downgrades from 2017 to 2021, analysts said during a presentation Monday at the Edison Electric Institute Financial Conference in Hollywood, Florida. U.S. power networks are also less reliable than those in other industrialized countries, they said. 

“Climate change is expected to continue to challenge electric reliability,” said Fitch analyst Barbara Chapman.
