(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:

  1. Battery
    1. Must be interconnected per utility guidelines.
  2. Customer criteria
    1. Must be on a Maine utility residential or business (Small General Service, or General Service) rate.
    2. May also have solar generation, but it is not required.

Program Partners

You can only participate in the program through one of the Program Partners listed below.

Note: No Program Partners have joined yet. If you’d like your battery manufacturer or installer to become a Program Partner, contact them and encourage them to apply.
