Performance incentives for commercial energy storage systems are designed to encourage businesses to optimize their energy usage and support grid stability through the efficient operation of these systems. Here’s how they typically work:
Incentive Structure
- Enrollment: Businesses enroll their energy storage systems in active dispatch programs. These programs allow utilities to remotely control the energy storage systems during peak demand periods to reduce strain on the grid.
- Incentive Payment: The payment is usually based on the performance of the system during these peak periods. For example, incentives might be awarded per kilowatt (kW) contributed during dispatch events.
- Duration and Frequency: These events typically occur during summer and winter seasons when energy demand is highest. The events are usually of a set duration, such as three hours, and can occur multiple times throughout the incentive period.
Eligibility and Requirements
- System Requirements: The energy storage systems must meet certain criteria, such as having a minimum capacity (e.g., 20 kW) and efficiency level (e.g., 80% round-trip efficiency), and they must be certified by recognized testing labs (e.g., UL-listed).
- Data Monitoring: Systems must be able to collect and transmit interval data to facilitate performance monitoring.
- Contractual Obligations: Participants often need to sign a formal contract with the program administrators.
Examples of Programs
- Efficiency Maine’s Program: Offers performance-based incentives for commercial customers in Maine. Incentives are paid annually for five years based on load reduction during summer peak demand hours.
- Connecticut’s Program: Combines upfront rebates with performance incentives, with rates varying by season and year of service.
Performance incentives can significantly enhance the financial viability of commercial energy storage projects by providing ongoing revenue streams based on actual performance, encouraging businesses to adopt and optimize these systems.
