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 Connecticut home battery storage systems:
- Energy Storage Solutions (ESS)
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
You will not receive an up-front rebate and will make less in rewards, but we will draw power from your battery less often.
ConnectedSolutions for Connecticut battery customers will not accept new enrollments after December 1st, 2023. Energy Storage Solutions will be the sole offering for new enrollments after that date. Existing ConnectedSolutions customers will have the option to stay in ConnectedSolutions as long as we have the funding for it or transfer over to Energy Storage Solutions.
Both programs reward you for allowing us to use your battery system to lessen strain on the electric grid.
Detailed Comparison
There are key differences between Energy Storage Solutions and ConnectedSolutions. Learn more about when events will be called, how much you can earn in rewards, and more.
A battery event occurs when participants’ batteries are discharged toward the grid because demand on the New England electric grid is forecasted to approach its peak.
