Data Centers and Your Electric Bill — July 2026
Part of your electric bill is set years in advance at a PJM capacity auction — a mechanism explained in full here. Those auction prices have climbed sharply across the delivery years already priced. Energy trade press, covering PJM's own published load forecasts, widely attributes a large share of that climb to one thing: a surge in electricity demand from data centers being built across the PJM footprint.
The price trajectory, already sourced on this site
| Delivery year | Clearing price |
|---|---|
| 2025/2026 (Jun 2025 - May 2026) | $269.92/MW-day |
| 2026/2027 (Jun 2026 - May 2027) | $329.17/MW-day |
| 2027/2028 (Jun 2027 - May 2028) | $333.44/MW-day |
| 2028/2029 (Jun 2028 - May 2029) | $325.00/MW-day |
RTO-wide Base Residual Auction clearing prices, published by PJM Interconnection — the same figures used throughout the capacity charge explainer and every locked line on this site.
From the 2025/2026 price to the 2028/2029 price, the RTO-wide clearing rate moved by a factor of 1.20×. That move is a documented auction result, not a projection — what follows is reporting on why it happened.
What trade press attributes the increase to
PJM's own published load forecasts point to data centers as the largest single contributor to new electricity demand across the footprint — energy trade press covering those forecasts has reported figures including a multi-thousand-megawatt increase in forecasted peak load year over year attributed largely to data center expansion, and utilities across the footprint doubling their forecasts for new large-load additions through the early 2030s. PJM's Independent Market Monitor has separately attributed a substantial share of recent capacity-price increases specifically to data center-driven demand growth, though the exact share reported varies by auction and by publication.
These are third-party figures, not numbers this site has independently verified against a primary PJM or market-monitor report — treat this paragraph as a pointer to the reporting, not as a sourced statistic on the same footing as the auction prices above. For the primary reporting itself, search “PJM data center load forecast” and “PJM Independent Market Monitor data center capacity costs” for the most current coverage; both terms turn up ongoing trade-press analysis as new auction results are published.
What it means for your bill
Whatever the precise share attributable to data centers, the mechanism that puts it on your bill does not change: capacity costs are pooled RTO-wide and passed through to every customer in the footprint, whether or not a data center sits anywhere near their meter. Which states carry the largest projected impact and the documented $/MW-day-to-¢/kWh arithmetic are both already on this site — this page adds the why, not a new number to the bill itself.

Ohio average: $224/mo at 19.45¢/kWh (+11.9% YoY)
Your bill is 33.0% below the state average (≈771 kWh/mo at the state average price).
Where your bill is headed:
- locked2027/2028 delivery year (Jun 2027 - May 2028)+$0.23/mo
- locked2028/2029 delivery year (Jun 2028 - May 2029)-$0.23/mo
- trendIf the last 12 months' trend continues+$17.89/mo
“Locked” = PJM capacity auction prices already cleared (a floor - several utility zones cleared higher). “Trend” = the observed 12-month EIA trend extended, not a promise.

PJM capacity figures are Base Residual Auction clearing prices (RTO-wide), published by PJM Interconnection — the verified, sourced figures on this page. Claims about data center demand as a driver reflect trade-press reporting on PJM's own load forecasts and market monitor analysis, summarized above and not independently re-verified against a primary document by this site; treat that section as reporting, not as a dated, sourced statistic.
