FOR IMMEDIATE RELEASE -- MAY 13, 2010

JEFFERSON CITY---The Missouri Public Service Commission has adjusted the fuel and purchase power adjustment charge (FAC) as required by a tariff governing Union Electric Company d/b/a AmerenUE.

The FAC rider mechanism, which allows for this adjustment, was adopted in the last AmerenUE rate case and is in no way associated with the pending AmerenUE rate case that is currently before the Commission.  The FAC mechanism allows for an adjustment to address fuel and purchase power cost volatility. 

AmerenUE stated in its application that the proposed adjustment to customer rates reflects changes in its fuel and purchased power costs net of off-system sales revenues which were experienced during the four month period of October 1, 2009 through January 31, 2010.  The electric company stated that the factors driving the increase were lower off-system energy sales revenues due to economic conditions and lower power prices.   

The current FAC rider is approximately $0.15 per month on the average residential customer’s bill.  The new FAC rider will be approximately $1.52 per month on the average residential customer’s bill.  The change starts with the June billing month. 

On April 19, 2010, the PSC staff filed its recommendation indicating that AmerenUE’s tariff complies with the Commission’s order that established the company’s FAC and with all applicable statutes and regulations.  No other party, including the Office of the Public Counsel-the consumer’s advocate, opposed the PSC staff recommendation, objected to the tariff, or requested a hearing.

AmerenUE serves approximately 1.2 million electric customers in Missouri.
