The four biggest jumps in home power prices were all on one grid
PJM runs the grid for 13 states and DC. In June 2025, the price it pays power plants to stand by for peak demand rose ninefold. Over the next year, home electricity prices rose 13.8% in six of its states, and 5.3% in states off the grid.

About the data
- Price is what homes paid divided by the kilowatt-hours they used, over twelve months.
- The six PJM states with retail choice are NJ, PA, MD, DE, DC and OH. Most homes there get default supply bought at auction, so the capacity price feeds straight into bills.
- In the year before, both groups rose about the same: 3.3% and 3.5%. PJM states also rose faster in 2023 and 2024, after the 2022 gas spike, but by 4.2 points at most. This year the gap was 8.5 points.
- Gas rose too, 24% at Henry Hub, but that hit every state.
- VA and WV are on PJM's grid too, but their utilities own most of their plants and pay less of the capacity price. Prices there rose 8.6%. States only partly on the grid (IL, MI, NC, TN, KY and IN) are in neither group.
- PJM's market monitor says data centers added $9.3 billion to the 2025/26 capacity bill. The price has stayed near the auction's cap since.
- EIA's 2025 and 2026 figures are preliminary and don't net out New Jersey's $100 bill credit.
