Ameren Missouri Announces the Largest Energy Efficiency Program in the History of the State
Total Customer Benefits of Approximately $500 Million Estimated Over the Next 20 Years

Today, Ameren Missouri announced the Missouri Public Service Commission (MPSC) has approved the Company's filing under the Missouri Energy Efficiency Investment Act (MEEIA). Ameren Missouri will invest $147 million in energy efficiency programs over the next three years, making Ameren Missouri's portfolio of energy efficiency programs the largest in the state's history.

"Customers will have new opportunities to help lower their energy usage beginning in January of 2013," says Michael Moehn, senior vice president of Customer Operations, Ameren Missouri. “Our new energy efficiency plan will benefit customers, the state of Missouri, and the environment."

In July various parties, including the MPSC Staff, Office of Public Counsel, Missouri Department of Natural Resources, environmental interveners, and industrial customers, signed an agreement to support a modified version of Ameren Missouri's MEEIA plan, which was ultimately approved by the MPSC.

“Our energy efficiency program continues the significant commitment we have made to energy efficiency in the past,” says Warner L. Baxter, chairman, president and CEO, Ameren Missouri. “Our current investments are expected to result in approximately $500 million in total customer benefits over the next 20 years. Annual energy savings are expected to be nearly 800 million kilowatt-hours, which is equal to the energy consumption of more than 60,000 average Missouri homes annually."
