Get Paid

Your installer will receive the upfront incentive once we have verified the battery system is communicating and it is consistent with the application. You will receive the performance incentives directly from the Connecticut Green Bank. 


Upfront incentive of $250/kWh
for a new battery system.

 That’s $7,350 off a 29.4 kWh
Avalon battery system!


We make sure that your battery
doesn’t discharge when extreme
weather threatens a power outage.


Participation incentive of $200/kW
and $25/kW for performance in the
summer and winter seasons.

That’s $1,411 additional revenue in
year one with a Fortress Power
11.4 kW Avalon system.

The Connecticut Energy Storage Solutions incentives larger energy capacity systems. Talk to your installer or email us at [email protected] to discuss how to maximize your investment in solar and storage. 


  • Your utility dispatches part of your battery instead of dirty, expensive peaker plants when the grid is stressed. This helps keep your air clean and bills low.

  • Fortress Power will ensure your battery is recharged the next day from solar power.

  • The average power provided in each event across the season is calculated. This power level is used to calculate the summer or winter performance payment to the battery system owner.



Home and business owners are eligible for Energy Storage Solutions incentives if they:

  • Own the premise where equipment is installed
  • Have consistent and reliable Internet connection
  • Charge their battery from an onsite solar system
  • Own the following hardware:
