Grid energy storage subsidies

What are energy storage incentive programs?

The energy storage incentive programs considered in this report fall into three categories: 1. Rebates (payment for installing storage) 2. Performance incentives (payment for storage services provided to a utility or grid operator) 3.

What are the different types of energy storage incentives?

In addition, there are other types of energy storage incentives that have been tried. For example, storage may be added to existing renewable programs, such as solar incentive programs, or be made eligible for market-based programs such as utility renewable portfolio standards (RPS).

Are incentive rates good for energy storage?

For example, New York offers relatively low per-kWh incentive rates, but its programs are nearly fully subscribed. By contrast, Connecticut offers relatively high incentive rates but its residential program has been under-subscribed. • Incentive rates alone do not convey a comprehensive economic story for energy storage in a state.

Are state incentives necessary to increase distributed storage deployment?

• Despite all these variables, numerous studies as well as experience have shown that until energy markets mature, battery prices fall, and currently non-monetizable energy storage services become monetizable, state incentives are a necessary and critical key to increasing distributed storage deployment.

Do energy storage developers offer financing?

While many energy storage developers offer financing, it can be helpful for the state to provide public financing options that can be marketed to income-qualified customers and historically underserved communities (for example, low- or no-interest loans that do not require high credit scores to qualify).

What are examples of energy storage equity provisions?

Examples of energy storage equity provisions include the following: • Justice40 commitment/Carve-out. Typically, a carve-out is necessary to ensure historically overburdened communities and income-eligible customers can participate in energy storage incentive programs.
