Ameren Illinois Distributed Generation Rebate Program

Ameren Illinois offers rebates for inverters used to interconnect renewable generators or energy storage systems. The rebate is available to any residential customer regardless of which tariff they use to monetize the output of their generation (i.e. either Rider NM – Net Metering or Rider QF – Qualifying Facilities) or who they use to provide their electric supply service. 

For DS-1 & DS-2 (residential and small commercial) the rebate for inverters used to interconnect generators are $300/KW-DC, and the rebate available for inverters used to connect ESS is $300/KW-hour, and they're available to both customers with existing generation and/or energy storage system (ESS, or battery) at their home/business and to customers who will be installing that equipment in the future.

For DS-3, DS-4 & DS-6 the rebate for inverters used to interconnect generators are $250/KW-DC, and the rebate available for inverters used to connect ESS is $250/KW-hour, and they're available to both customers with existing generation and/or ESS at their business and to customers who will be installing that equipment in the future. There is a limit of a 5MW AC for the rebate application.

Customers served under net metering that receive a rebate will no longer have credits for any excess generation pushed to the grid applied to their delivery service charges. All residential customers receiving an energy storage system rebate will be required to receive service under Peak Time Rewards, Real Time Pricing, or Power Smart Pricing. However, if an application is made only for the ESS and not for the generator, a residential customer receiving service under Rider NM – Net Metering can continue receiving delivery service credits for excess generation pushed to the grid. All DS-2 (small commercial) customers receiving a rebate will be required to receive service under Real Time Pricing. For DS-3, DS-4, & DS-6, Receipt of a rebate that's tied to the generator or energy storage system triggers the requirement to participate in one or more programs determined through the Multi-Year Integrated Grid Planning process as they become available.
