For commercial and industrial (C&I) building owners, batteries can increase storm preparedness by providing backup power when the grid goes down. Even more beneficial, batteries provide an opportunity to manage your monthly peak demand costs, saving you money on blue-sky days.
If you install a battery alongside solar photovoltaic (PV) panels, you can charge when the sun is out, further increasing your opportunity for energy savings.
*Note that metering and billing differs for solar + battery customers and standalone storage customers. Contact Eversource or UI with questions.
The Energy Storage Solutions program provides both upfront and performance incentives to reduce the cost of installing battery storage systems.:
Upfront incentives reduce up to 50% of the battery’s cost in exchange for allowing the battery to reduce electrical grid stress on summer days for 10 years.
Performance incentives are paid twice a year for 10 years based on how much average power the battery contributes to the grid during critical periods.
