The Missouri Public Service Commission approved an application filed by Ameren Missouri to implement renewable energy standard rate adjustment mechanism (RESRAM) charge on the monthly bills of its electric customers, the commission said Friday.

The charge will appear as a separate item on the monthly electric bills of Ameren Missouri customers. The RESRAM charge is designed to recovery costs associated with Missouri’s Renewable Energy Standard. 

A RESRAM allows electric companies to adjust rates outside of a general electric rate case to reflect prudently incurred renewable energy standard costs — such as solar and wind. These costs would be costs above renewable energy costs already included in the company’s base rates, according to the commission.

For a residential customer using 1,000 kilowatt-hours of electricity a month, the RESRAM charge will be 44 cents a month. The commission said it is expected to take effect on Feb. 1, 2020. 

Ameren Missouri serves 1.28 million electric customers in Missouri.
