Energy Storage Solutions
Utility customers who install battery storage within Eversource and UI territory may qualify for the Energy Storage Solutions Rebate through Connecticut Greenbank. This program features an initial upfront rebate of $200 per kWh of storage capacity installed with a cap of $7,500. For example, an 18kWh battery would be eligible for a $3,600 upfront rebate.
Residential customers enrolled in this program will also receive performance incentive payments every year based on the average power their battery contributes to the grid during critical periods. Depending on the kW rating of your storage system, you can get paid over $1,000 per year on average.
