Connecticut Home Battery Storage Options

We have two options for customers to earn rewards using home batteries in Connecticut. Find the program that's right for you.

What is a Home Battery Storage System?

Equipping your house with home battery storage can help you be more prepared as storms become more frequent. You can charge your battery in good weather and rely on it to power your essential appliances when the power goes out.

Charging your battery

You can charge your battery using the grid or a solar photovoltaic (PV) system, and there are a number of different battery sizes, options and manufacturers, so you can find the one that's right for your home.

Benefits compared to generators

Unlike gasoline-powered generators, a home battery system requires no set-up when you lose power, has no risk of carbon-monoxide poisoning, and does not emit greenhouse gasses.

Which Program is Right for You?

Eversource offers two rewards programs for home battery storage systems: 

  • Energy Storage Solutions
    You'll access an up-front rebate up to 50% of the cost of your battery system, and likely be rewarded more for alleviating strain on the grid.

  • ConnectedSolutions Demand Response
    You will not receive an up-front rebate and will make less in rewards, but we will draw power from your battery less often.

Both programs reward you for allowing us to use your battery system to lessen strain on the electric grid. Choose a path to get more program details and sign up, or view our comparison chart below to decide which program is right for you.
