Residential electricity prices have seen significant year-over-year increases in various parts of the United States, with Washington D.C. leading the surge at 22.5%. New Jersey and New Hampshire followed with increases of 18.2% and 18.0%, respectively. The national average increase stood at 10.2%. This rise is attributed to a combination of factors including escalating grid investment costs, increased electricity demand driven by AI data centers and electrification trends, and the strain on aging infrastructure. In contrast, some Western states and Northeastern areas like Rhode Island and Connecticut experienced price declines. The PJM Interconnection, a major Eastern U.S. power market, saw wholesale electricity prices jump 76% due to accelerated data center demand, with analysts suggesting these costs may be passed on to consumers. This divergence highlights a growing divide in electricity costs across regions, making utility bills a more volatile expense for households.
