These two pair nicely – Community Solar & Battery Storage

The battery storage project on Decatur is located in the center of the island on 3.6 acres within our main transmission substation and in proximity to our community solar project. The community solar project is a 504 kW DC array that produces approximately 570,000 kWh per year and began producing energy in 2018.

Some of our goals with this project are:

  • enhanced safety
  • reduce operating costs (through efficiencies and peak shaving)
  • improve reliability of the current infrastructure while speeding the transition to locally produced renewable energy.

OPALCO’s storage system improves the output of the Decatur Island Community Solar project. As energy costs rise with carbon legislation and fees, OPALCO plans to decrease our reliance on mainland resources through a system of microgrids. This investment today will help manage energy costs for members into the future.
