Connecticut Light and Power Company d/b/a Eversource Energy

Eversource does not offer a residential EV-specific time-of-use rate in Connecticut. Residential customers pay the standard residential rate by default, and those who want time-varying pricing can opt into the general Time-Of-Day Rate 7, where on-peak hours run noon to 8pm on weekdays and everything else, including weekends, is off-peak. The way most Connecticut EV owners earn an overnight charging benefit is not through a tariff at all but through the Eversource managed-charging program, which rewards charging outside the weekday 3pm to 9pm peak. Commercial charging sites are different: separately metered public chargers, and qualifying private fast-charging or managed workplace and fleet sites, can move onto the Light Duty EV rates. Sites with demand of 100 kW or more land on EV-M or EV-L, which split the weekday into on-peak and off-peak periods and price the rest by the site's load factor, a structure meant to soften demand charges for chargers that are used only a few hours a day.

The residential charger and wiring rebate, worth up to $1,500, requires enrollment in managed charging, so the two programs are designed to work together rather than separately. As of January 1, 2026, that upfront rebate is limited to households at or below 300 percent of the federal poverty level or living in High Poverty, Low Opportunity areas, a change required by Connecticut SB 4, signed July 1, 2025. The commercial and multifamily track is separate and broader: make-ready infrastructure can be covered up to 100 percent in some cases, with EVSE equipment rebates up to 50 percent of cost.

What makes Connecticut distinctive is that the EV programs are statewide and identical across utilities by design. PURA authorized a single nine-year program in Docket 17-12-03RE04, and Eversource and United Illuminating each run the same offerings in their own service territories. An EV owner's options therefore depend on which utility delivers their power, not on shopping between programs, and the rebate rules reflect state policy rather than one company's choices.
