Springfield, IL, U.S.A. --- (METERING.COM) --- February 14, 2008 – The Ameren Illinois Utilities have filed an energy efficiency plan with the Illinois Commerce Commission (ICC) designed to help customers save money by reducing their natural gas usage.

"Through this comprehensive natural gas energy efficiency plan, we will help customers save money by using less natural gas without sacrificing personal comfort or safety," said Stan Ogden, vice president for Customer Service and Public Relations for the Ameren Illinois Utilities (AmerenCILCO, AmerenCIPS and AmerenIP).

Ogden said this natural gas energy efficiency plan will complement the Ameren Illinois Utilities' comprehensive electric energy efficiency plan that was approved by the ICC on Feb. 6, 2008.

"Natural gas energy efficiency initiatives will allow customers to take advantage of a range of incentives that not only will help reduce natural gas usage, but will help lower electrical usage as well," Ogden said. "Working in tandem, these two programs can provide customers with the tools they need to better control their energy usage and realize significant dollar savings through lower monthly natural gas and electric bills. Furthermore, by using less natural gas and electricity at home, we can reduce greenhouse gas emissions and better protect our environment."

The natural gas energy efficiency plan will begin in January 2009, when customers will be given a variety of options from which to cut their energy costs. By the end of the program's first year, the Ameren Illinois Utilities estimate the energy efficiency efforts will reduce natural gas usage by an amount sufficient to serve about 1,400 single family homes for a year. In the second year, the goal is to reduce usage by an amount equal to the natural gas needed to supply about 2,800 single family homes for one year. By the end of the third year, the target is to reduce usage by an amount equal to the annual natural gas requirements of about 4,200 homes.

The energy efficiency programs will be funded by a small ICC-approved charge that will appear on customer bills. For a residential customer using 750 therms per year, this charge will average about 36 cents per month. Customers who improve their energy efficiency at homes or at their businesses can anticipate savings well in excess of this small charge.
