Where the increases are concentrated
7 of the 10 largest increases are in states served wholly or partly by PJM, the grid operator for 13 Mid-Atlantic and Midwest states and DC. The middle (median) PJM state rose 10.1%; the middle state elsewhere rose 5.6%.
Grid region is not the only cause: a state's price also moves with its utilities' delivery charges, fuel costs and state policy. PJM's independent market monitor has linked much of the region's higher capacity costs to forecast demand from data centers (State of the Market reports). EIA's Short-Term Energy Outlook forecasts prices nationally each month. We report the price change; we do not attribute it to one cause.

Why a 12-month average and not one month
News stories often compare one month with the same month a year earlier. That figure swings with a single fuel-cost adjustment or a billing change, and with how much air conditioning or heating happened to fall in that month. In this data, Hawaii was +22.5% for August 2026 alone but +8.9% over 12 months; New Jersey was −0.4% for August 2026 alone but +12.4% over 12 months; Connecticut was −18.8% for August 2026 alone but −8.8% over 12 months. Averaging a full year of prices on both sides compares like with like.
The bill effect assumes your use stays at your state's typical level. A home with electric heat uses far more in winter, so its dollar change is larger.
