Natural Gas Rates To Drop For Ameren Missouri Customers

JEFFERSON CITY---To reflect estimated changes in the wholesale cost of natural gas as well as a change in the company’s Actual Cost Adjustment (ACA) factor, Union Electric Company d/b/a Ameren Missouri natural gas customers will see natural gas rates drop under a filing that takes effect on November 1, 2012. 
The ACA factor is a mechanism which tracks any over-collection or under-collection of actual natural gas costs over a 12 month period.  The net over- or under-collected balances are subsequently either refunded or collected the next year.
Ameren Missouri residential customers in all of its service areas except Rolla will see natural gas rates drop by approximately $0.08 per Ccf (per hundred cubic feet of natural gas).  This change will affect Ameren Missouri natural gas customers in areas such as Columbia, Jefferson City, Mexico, Wentzville, Cape Girardeau and Marble Hill.  
Residential customers in Ameren Missouri’s Rolla service area (Rolla, Salem and Owensville) will see natural gas rates decrease by approximately $0.06 per Ccf. 
The PSC continues to encourage customers to work to reduce their energy consumption.  A number of energy saving tips can be found on a website (www.beenergyefficient.org) from the Missouri Public Service Commission and the Missouri Department of Natural Resources.
Approximately 65% to 75% of a customer’s natural gas bill reflects the cost of natural gas from wholesale suppliers.  The wholesale cost of natural gas (the cost your local natural gas company must pay to its suppliers for natural gas) is not regulated by the Missouri Public Service Commission.  The wellhead cost of natural gas is unregulated and is primarily driven by supply, demand and the weather.  The Missouri Public Service Commission does conduct an annual regulatory review to ensure that regulated natural gas companies make prudent decisions in securing natural gas supplies for their customers.
Ameren Missouri serves approximately 126,700 natural gas customers in Missouri.
