Ameren Missouri offers a Standard Offer Contract to customers that generate solar power. The customer must meet Ameren's net metering requirements and submit an application for net metering. The [http://www.ameren.com/sites/aue/Rates/Documents/umbe12216rdSP.pdf 2013 SREC tariff] is $5 per SREC, which is down significantly from the 2012 rate of $50 per SREC.
For systems of less than 10 kW, Ameren will pay an up-front, lump sum payment for the estimated number of Solar Renewable Energy Credits (SRECs) that will be produced for 10 years. The estimated 10-year production will be calculated by Ameren using PVWatts software.
For systems of 10 kW to 100 kW, Ameren offers a 10-year contract for the SRECs, and will make annual payments to the customer based on the number of SRECs produced in the previous year.
