PJM Capacity Prices Rose 833% in Two Years — What It Could Mean for Household Bills
Capacity prices in the PJM Interconnection market — the grid operator serving all or part of 13 mid-Atlantic and Midwest states plus Washington, D.C. — rose 833% between the 2024-25 and 2025-26 delivery years, driven largely by data center demand growth, according to industry tracking summarized by iRecruit's 2026 power and energy news roundup.
The Federal Reserve Bank of Dallas has separately estimated that if data center electricity demand doubles over the next five years as projected, wholesale power prices in affected regions could rise by as much as 50%, according to reporting from Spotlight PA.
Regulators have introduced measures requiring data centers to cover more of the associated grid upgrade costs directly, aiming to limit how much of the increase reaches residential ratepayers, though the mechanics of cost allocation remain an active and contested regulatory process, per The Conversation's analysis of utility cost allocation.
For residential customers in PJM territory, the practical effect may unfold gradually through generation and transmission charges on future bills rather than all at once — a reason to track your own energy burden over time rather than react to any single month's bill.
