(review) Small Battery Incentives
Intro
When the electric grid goes down, batteries can power heating systems, refrigerators, well pumps, and other electrical loads in your home or small business. In addition, if you switch to your utility’s time-of-use rate, batteries can save you hundreds of dollars each year by making low-cost power stored off-peak available during on-peak periods. Finally, batteries can earn you incentives if you participate in a battery program offered by an Efficiency Maine Small Battery Program Partner, who pays you to let them discharge your battery to the grid when demand is peaking.
Incentive
Efficiency Maine pays Program Partners $200 per year per average kW discharged during peak load events. Program Partners sign 10-year agreements with Efficiency Maine. The incentive you receive from the Program Partner is set by them.
Here’s an example of your potential incentive: For a battery that discharges an average of 4 kW across a year of events, Efficiency Maine would pay the Program Partner $800. If the Program Partner passes on 50% of this incentive, the battery owner would earn $400 per year. Over the course of 10 years, the battery owner would earn $4,000.
Eligibility
Here are the eligibility requirements for the Small Battery Program:
- Battery
