Compare Connecticut's two utility EV programs side by side. TOU rate savings, managed charging rebates, multifamily incentives, and the optimal solar + EV + battery strategy. The Section 30C federal credit expired June 30, 2026 — Energize CT rebates and off-peak TOU rates now carry the savings.
Connecticut's two investor-owned utilities — Eversource and United Illuminating — both offer EV managed charging programs that pay you for flexibility. When the grid is under stress (typically a few summer afternoons per year), your smart charger briefly reduces its power draw. In return, you earn rebates and bill credits. Your car still charges — and most participants never notice the difference.
Combined with TOU (time-of-use) rates and Energize CT incentives, Connecticut EV owners can dramatically reduce their fueling costs. Add solar and battery storage, and you can achieve near-zero transportation energy costs while earning thousands in annual demand response rebates.
Charge off-peak and save $0.08-$0.12/kWh versus on-peak rates on both Eversource and UI.
The triple play: solar offsets EV charging, battery earns ConnectedSolutions rebates, smart charger avoids peak rates.
The federal EV-charger credit expired June 30, 2026. Energize CT and utility charger rebates remain available.
Earn $50-$100/summer for smart charger demand response. 10-15 events per season, 1-3 hours each.
11 PM - 7 AM daily. Save $0.08-$0.12/kWh versus on-peak.
Up to $300 for new smart charger installations that commit to 2+ years of managed charging.
$350-$500/year
UI's pilot program offers $40-$80/summer for managed charging participation with compatible smart chargers.
9 PM - 12 PM (noon). 15-hour off-peak window — the most generous in CT.
UI offers additional multifamily incentives of up to $4,000/port for properties with 5+ units.
$340-$480/year
If you're in Eversource territory, you get a slightly larger managed charging rebate and established ConnectedSolutions integration. If you're in UI territory, you get a more generous off-peak window (15 hours vs 8 hours) and stronger multifamily incentives. Either way, you'll save $300-$500 per year on EV charging costs before adding solar.
Time-of-use rates are the foundation of EV charging savings. Both Eversource CT and United Illuminating offer TOU plans that reward overnight and off-peak charging with significantly lower per-kWh rates.
| Utility | Off-Peak Hours | On-Peak Hours | Est. Savings/yr |
|---|---|---|---|
| Eversource CT | 11 PM - 7 AM | Noon - 8 PM weekdays | $300-$450 |
| United Illuminating | 9 PM - 12 PM (noon) | Noon - 9 PM weekdays | $350-$500 |
United Illuminating's off-peak window runs 15 hours (9 PM - noon), compared to Eversource CT's 8 hours (11 PM - 7 AM). This means UI customers can charge through the entire morning at off-peak rates — ideal if you have solar panels producing during those hours. Weekend rates are off-peak all day for both utilities.
Energize CT administers statewide energy efficiency programs including EV charging incentives. Connecticut residents can access rebates for smart charger installations, and Smart-E loans offer low-interest financing for energy improvements including EV charger installations.
To participate in managed charging programs, your Level 2 charger must meet these requirements. Both Eversource CT and United Illuminating require smart chargers with demand response capabilities.
| Charger | Price | Amps/kW | Best For |
|---|---|---|---|
| ChargePoint Home Flex | $699 | 50A / 12 kW | Best app + utility integration |
| Emporia Smart Level 2 | $449 | 48A / 11.5 kW | Best value |
| JuiceBox 48A | $649 | 48A / 11.5 kW | Best green energy matching |
| Wallbox Pulsar Plus | $549 | 48A / 11.5 kW | Best solar integration |
Connecticut has recognized that multifamily properties are critical for EV adoption. Both utilities offer enhanced incentives for apartment buildings, condominiums, and housing complexes with 5 or more units. These programs cover both the charging equipment and the electrical infrastructure needed to support it.
Connecticut homeowners have a unique opportunity to combine solar panels, battery storage, and smart EV charging into a single integrated system. Each component multiplies the value of the others, and ConnectedSolutions demand response rebates for batteries are among the highest in the nation.
Produce clean electricity during the day. Net metering credits offset nighttime EV charging at 1:1. Add 8-10 panels for EV load.
Store solar for evening use. Earn $225/kWh per season from ConnectedSolutions. A 10 kWh battery = $2,250/year in rebates.
Charge off-peak using TOU rates or stored solar. Managed charging adds $50-$100/year in additional rebates.
Total annual value: $2,500-$3,500 in savings + rebates
The Section 30C credit covered 30% of EV charger equipment and installation costs, but it expired June 30, 2026 and is no longer available for chargers placed in service after that date. Section 25D (solar ITC) and Section 25C (heat pump credit) had already expired December 31, 2025. Connecticut EV owners should now rely on Energize CT / utility charger rebates and off-peak TOU rates.
Residential
Up to $1,000
30% of costs, max $1,000
Commercial
Up to $100,000
30% of costs, max $100,000
This credit expired June 30, 2026: only chargers placed in service on or before that date qualify, claimed on that tax year's return via Form 8911.
We design integrated solar + battery + EV charger systems for Connecticut homes. Managed charging compatible, ConnectedSolutions enrolled, and all rebate paperwork handled. The Section 30C federal credit expired June 30, 2026 — Energize CT rebates and off-peak TOU rates remain the active savings.
