EV & managed charging
EV managed charging: a $475 grid asset paid $120–$400
An electric car is the biggest flexible load most homes will ever have. The grid values that flexibility at hundreds of dollars a year. Here is how much drivers actually see — and why.

The short answer
- An EV is the biggest flexible load in most homes — often 7 kW or more while charging — and it usually sits plugged in overnight with hours to spare.
- Managed charging creates real value: WeaveGrid estimates about $475 per EV per year in avoided generation, transmission, distribution, and energy costs (WeaveGrid).
- Drivers are paid roughly $120 to $400 a year in today’s programs — Connecticut pays $10 or $25 a month; Con Edison averages about $400 (Eversource/UI, Con Edison).
- Bidirectional charging is the next step. Vehicle-to-grid (V2G) lets an EV export like a battery; pilots are starting in Massachusetts and Maryland.
Two different things called “managed charging”
Passive managed charging rewards you for charging off-peak on your own schedule. Con Edison’s SmartCharge New York pays 10 cents per kWh charged off-peak, plus $35 a summer month for staying off the charger from 2 to 6 p.m. on weekdays. That is load shifting, not dispatch.
Active managed charging lets the utility or a platform such as ev.energy or WeaveGrid pause and adjust charging in real time, as long as the car is ready by your deadline. Connecticut’s advanced tier pays $25 a month for this, versus $10 for the baseline (Eversource/UI). NYSEG’s OptimizEV offers $25 or $150 upfront depending on the tier (NYSEG).

Where the gap goes
The distance between $475 of value and a $120–$400 payment covers platform fees, utility administration, and the fact that value is highly local. Half the WeaveGrid estimate comes from deferring distribution upgrades — which only pays where a neighborhood transformer or feeder is actually near its limit. ev.energy, which runs SmartCharge for more than 27,000 EVs, puts managed charging at $145–$575 per EV per year and bidirectional charging at up to $1,320 (ev.energy).
Vehicle-to-grid is coming
Massachusetts is testing residential V2G inside ConnectedSolutions with EnergyHub, Sunrun, and The Mobility House for Eversource and National Grid customers (Business Wire). Maryland approved VPP and V2G pilots under its DRIVE Act for summer 2027 (Vehicle-Grid Integration Council). A bidirectional EV with a 60–80 kWh pack is, economically, a very large home battery — if your car, charger, and utility all support it.

Drive Economics compares EV and gas ownership costs, including EV time-of-use rates and incentives by state.
Method and caveats
The value stack is WeaveGrid’s published estimate and is not location-specific. Con Edison’s ~$400 is the utility’s stated average. Connecticut figures are the program’s published monthly incentives; the $100 enrollment bonus applies to customers who didn’t receive a charger rebate. Checked October 1, 2026.
