JEFFERSON CITY, Mo. (AP)- By a unanimous vote, Missouri regulators have approved a $172 million increase in electric rates for Ameren Missouri. The rate hike takes effect in August. The St. Louis-based utility expects the rate increase to raise the average residential bill about $8 dollars a month.
Even with the 5-0 vote, the Public Service Commission would not permit Ameren to recover costs it sought to rebuild the Taum Sauk reservoir.
The Public Service Commission decided against letting Ameren Missouri add part of the cost for building the new Taum Sauk reservoir into the rate base that is collected from electric customers over time. The original Taum Sauk reservoir collapsed in December of 2005 sending a billion gallons of water down a southeastern Missouri mountain.
St. Louis-based Ameren Missouri is the state’s largest electric utility with about 1.2 million customers, mostly in eastern and central Missouri.
