2026 Commercial Electricity Rates: State-by-State Comparison
The following table uses verified data from the EIA Electric Power Monthly (January 2026 release, published March 24, 2026). Rates represent the average revenue per kilowatt-hour for commercial-sector customers, which is the EIA’s standard proxy for retail electricity prices.

Why Commercial Rates Are Rising in 2026
Three structural forces are pushing commercial electricity costs higher across all major ISOs:
- Capacity Market Repricing: PJM’s 2026/2027 Base Residual Auction cleared at a record $329.17/MW-day across the entire RTO — a 22% increase over the previous year’s $269.92/MW-day. This directly flows into capacity charges on commercial bills in PA, OH, NJ, IL (ComEd), MD, VA, and DC starting June 2026.
- Natural Gas Basis Volatility: Henry Hub sits at $2.90/MMBtu (EIA projects $3.80 annual average for 2026), but regional basis premiums tell a different story. Transco Zone 6 (NYC) surged 120% year-over-year in 2025, and Algonquin (ISO-NE) remains structurally constrained, driving New England’s 24–26¢ rates.
- Grid Modernization Cost Pass-Through: Con Edison’s approved 3.5% delivery rate increase (2026), along with similar filings from National Grid, ComEd, and PSEG, reflect billions in infrastructure upgrades being socialized across ratepayers.
What This Means for Commercial Buyers
The data reveals a clear geographic arbitrage opportunity. Businesses in deregulated states can act on the spread between their current utility default rate and competitive supplier offers:
- PJM states (PA, OH, NJ, IL, MD): Lock fixed-rate supply contracts before the $329.17/MW-day capacity charges flow through starting June 1, 2026.
- ISO-NE states (MA, CT, NH, ME): Consider blended index+fixed structures. Winter basis volatility makes full-index exposure risky, but locking 100% fixed leaves money on the table during mild shoulder months.
- MISO states (IL downstate, IN, MI, WI): Watch the April 28 MISO PRA results. A higher-than-expected clearing price could shift Midwest commercial rates upward by Q3 2026.
