Rate Case Decision 
 

On Feb. 3, 2012, Ameren Missouri filed a rate case in order to recover investments we already incurred for safe and reliable energy for the benefit of our customers, shareholders, and the entire state of Missouri. The Missouri Public Service Commission (MPSC) approved a $260 million electric rate increase effective Jan. 2.


  • That is an average increase of about 10% for all of our customers. For a residential customer that equals about 34 cents a day.
  • Our allowed return on investment is now 9.8%, which is slightly below the current national average for electric companies.
  • We will continue to reflect changes in our fuel costs on customers' bills through the fuel adjustment clause.
  • The MPSC formally approved our portfolio of energy efficiency (EE) programs, which is the largest in Missouri's history. We are investing nearly $150 million in EE over the next three years to help customers manager their energy usage and bills. These programs will result in more than $500 million in customer benefits over the next 20 years.
