Connecticut Electric Supply Rates Decline for Summer 2026
What Eversource and UI Customers Should Know.
Connecticut electricity customers will see some relief heading into the second half of 2026, as both Eversource and United Illuminating (UI) have filed lower default service supply rates effective July 1, 2026. The new rates reflect easing wholesale electricity market conditions and will provide modest savings opportunities for both residential and small commercial customers across the state.
For organizations and residents alike, the rate changes also serve as a reminder of how quickly energy markets can shift, reinforcing the importance of proactive energy procurement and long-term planning.
Eversource (CL&P) Rates Declining This Summer
Eversource’s Connecticut Light & Power (CL&P) territory filed new Standard Service and Last Resort Service rates with the Connecticut PURA for the upcoming pricing periods.
Beginning July 1, 2026:
- Residential (Rate 1) Standard Service rates will decrease to 11.577¢/kWh, down approximately 8% from the current rate of 12.641¢/kWh.
- Small commercial customers on Rates 30 and 35 will see rates decrease to 11.229¢/kWh, about 5% lower than the current 11.774¢/kWh rate.
The updated rates include the bypassable Federally Mandated Congestion Charge (FMCC), which will shift to -0.210¢/kWh beginning in July.
UI Customers Also Seeing Meaningful Reductions
United Illuminating customers will experience even larger percentage decreases beginning July 1, 2026.
Under UI’s newly filed Standard Service rates:
- Residential (Rate R) customers will see rates decline to 11.9865¢/kWh, a reduction of approximately 12% from the current 13.6950¢/kWh rate.
- Small commercial customers on Rate GS will see rates decrease to 11.9022¢/kWh, roughly 11% lower than current pricing levels.
Unlike Eversource territory, UI’s bypassable FMCC will remain at 0.0000¢/kWh.
What This Means for Connecticut Energy Customers
While these reductions are welcome news, energy markets remain inherently volatile. Wholesale electricity prices continue to be influenced by natural gas supply constraints, transmission costs, regional capacity markets, and environmental policy developments throughout the Northeast.
For businesses, municipalities, healthcare organizations, and senior living communities, lower utility default rates may create short-term savings opportunities but they should not replace a long-term procurement strategy.
Default service rates are reset periodically and can fluctuate significantly from season to season. Organizations that rely solely on utility supply may remain exposed to future market spikes and budgeting uncertainty.
