Residential electricity prices went up in most states between August 2024 and August 2025, but the size of the increase was very different across the country. Some of the biggest jumps were in the Northeast and Mid Atlantic. Maine rose by 4.48 cents per kilowatt-hour, New Jersey rose by 4.33 cents, and the District of Columbia rose by 5.79 cents. Other large states, including New York, Massachusetts, Pennsylvania, Illinois, and Florida, had moderate increases of around 1 to 2.5 cents.
Many states in the South, Midwest, and Mountain West saw only small changes of less than 1 cent. A few states even saw prices go down. Rhode Island fell by 0.31 cents, Nevada fell by 1.15 cents, and Hawaii fell by 3.36 cents. These differences show that each state’s electricity prices depend on many local factors, such as fuel costs, rules set by state regulators, new investments, and local demand.
