Incentives are available for the initial purchase and installation of a battery system and performance incentives based on the system’s contribution to the grid during peak demand.

Energy Storage Solutions is a statewide offer designed to help Eversource and United Illuminating (UI) customers install battery storage at their home or business. Benefits of on-site energy storage include:

  • Backup power during power outages for critical appliances or systems
  • Ongoing incentives for allowing your battery to be a power source for the grid
  • A more resilient, secure Connecticut as we face climate change
