Ameren Missouri - Solar PV Rebates

March 05, 2015


Note: Ameren Missouri's solar rebate program is fully subscribed to the $91.9 million funding level. Ameren Missouri does not anticipate making any additional funding available.

Ameren Missouri offers rebates to its customers for the installation of net metered photovoltaic (PV) systems on their properties. The rebate is set at $2.00 per DC watt with a maximum rebate of $50,000. Systems of 100 kW or less (the maximum size allowed under Missouri's net metering rules) qualify for rebates on the first 25 kW of installed capacity. Only systems that become operational after December 31, 2009 are eligible for the rebate. Beginning in July 2014, the incentive rates will decline until they are phased out in July 2020.

In order to qualify for incentives, a customer must have an electric account in good standing with the utility. Eligible systems must use new equipment; be permanently installed on the customer's property; and have module and inverter manufacturer's warranties of at least 10 years. Installations must comply with all applicable federal, state and local codes and standards, including the state of Missouri's Interconnection Standards. Rebate recipients must certify that the system will remain in operation on their property for its useful life (deemed to be a minimum of 10 years). Notably, the customer retains ownership of all solar renewable energy certificates (SRECs) generated by the system.

This program arises from 2008 Proposition C, a ballot initiative that established a state renewable portfolio standard in Missouri and required the state's investor-owned utilities to offer solar rebates of at least $2.00 per watt beginning in 2010.
