The Missouri Public Service Commission has approved a filing made by Union Electric Company d/b/a Ameren Missouri to change the Delivery Charge Adjustment  (DCA) on the bills of Ameren Missouri natural gas customers.  

The establishment of the DCA was part of an agreement reached by parties in a natural gas general rate case filed by Ameren Missouri in December of 2018. The Public Service Commission approved that agreement in August of 2019.  

Under state law, the Commission may authorize a natural gas utility to make rate adjustments outside of a general rate case to reflect non-gas revenue effects of increases or decreases in residential and commercial customer usage, but only if the revenue effects are due to variations in either weather, conservation or both. 

The current DCA for a residential customer is approximately $0.0158 per Ccf (per hundred cubic feet) of natural gas. As a result of this adjustment, the DCA will drop to roughly $0.0085  per Ccf starting on November 1, 2021. A residential customer that uses 100 Ccf’s a month will experience a decrease in their bill of approximately $0.73 a month.  

Ameren Missouri provides natural gas service to approximately 135,000 customers in  Missouri.
