What it could mean for power bills
Grid region costs rising (PJM)
In PJM, the grid serving 13 states from Illinois to New Jersey, a record capacity auction pushed power costs up, with data centers named the main driver. Monthly bills were expected to rise more than 5%; in Columbus, Ohio, about $27 a month.
The US Energy Information Administration expects average home electricity prices to reach 18.2 cents per kWh in 2026, almost 5% higher than 2025, with demand from businesses including data centers a key reason. Some East Coast areas may see up to 7% a year.
