AmerenUE Seeks to Recover Costs for Reliability Improvements and Cleaner Air

UE is asking for a $263 million rate increase. If approved, that would be an increase of about 11 percent for customers across all rate classes. Average residential electric bills would increase by about 31 cents a day (based on approximately 1,100 kilowatthours of usage per month).

    --  UE is seeking to recover investments made primarily to improve the
        reliability of its aging infrastructure and comply with environmental
        regulations.  Approximately $200 million (~75 percent) of the increase
        request is due to energy infrastructure investments, environmental
        controls, and other reliability costs to meet customers' expectations of
        more reliable and greener energy. More than $1 billion of new energy
        infrastructure investments will be serving customers when new rates from
        this case go into effect.
    --  In particular, UE is seeking to recover the cost of installing two
        scrubbers at the company's Sioux Power Plant at a cost of approximately
        $600 million.  These scrubbers will eliminate nearly 100 percent of
        sulfur dioxide emissions from the plant, providing cleaner air for the
        Midwest. (Approximately $110 million of the $263 million request relates
        to the Sioux scrubber project.)
    --  Higher net fuel costs for power plants account for approximately 25
        percent, or around $70 million, of the request.
    --  UE understands that this electric rate increase, coupled with the
        challenging economy, will create a hardship for some of its customers. 
        UE is taking several proactive steps to help its customers with their
        future energy bills by reducing its costs and providing energy
        efficiency and energy assistance programs to its customers.
    --  The MPSC and many other parties will review UE's request. The process
        typically takes 11 months.
    --  Today, UE's residential rates are approximately 35 percent below the
        national average and the lowest of any investor-owned utility in
        Missouri.

A significant portion of this rate case is to recover infrastructure investments UE is making to serve its customers. Infrastructure investments are a key driver in this case and future cases because of the need to meet stricter environmental regulations and make improvements to an aging infrastructure to meet customers' number one priority - reliability.

"Our customers have consistently told us that reliability is their highest priority and that they also want cleaner air," said AmerenUE President and CEO Warner Baxter. "The investments that we have made are consistent with our commitment to deliver the safe, reliable, affordable and environmentally responsible service our customers expect."

Building two scrubbers at the Sioux Power Plant is an approximately $600 million investment to reduce air emissions from the plant. UE is taking a proactive approach to protecting Missouri and the Midwest by implementing these environmental measures, which will keep 45,000 tons of sulfur dioxide emissions from going into the air next year.

Installation of the two scrubbers began in 2006. The scrubbers are expected to begin operations by the end of 2010. So far, UE has not recovered any of these investments in customers' rates. Under the regulatory framework in Missouri, UE must first spend money and have the investments serving customers before the company can recover those costs in rates. This delay, or "regulatory lag," can be as long as 18 months to several years after the company makes an investment. In the case of the Sioux scrubber project, it will take more than four years. Regulatory lag reduces the cash the company has available from its operations for future reliability projects or to meet future regulatory requirements. Therefore, it has been necessary for UE to file for frequent rate increases to recover its costs.

UE also made infrastructure improvements at its Taum Sauk Power Plant. Customers are not paying for the rebuilding of the upper reservoir, and UE is not seeking to recover costs already paid by insurance carriers. However, the company is able to seek recovery of enhancement costs or costs that would have been necessary absent the breach. These enhancements were made to improve the safety, security and reliability of the plant, while providing a cleaner source of power for at least another 80 years. In addition, some of these enhancements would have been needed to the old reservoir to meet current federal dam safety standards. Enhancements include: more robust construction to comply with more stringent earthquake standards; a new, state-of-the-art instrumentation and controls system; an overflow release structure; and a drainage gallery - where operators and engineers are able to monitor the "health" of the new dam. UE is seeking to recover $15 million in Taum Sauk investments in this rate request, or about 6 percent of the total request.

In addition, net fuel costs are rising, primarily because UE is paying higher coal prices for fuel to generate electricity and higher costs to transport the coal to its facilities.

While UE must recover its costs and make a reasonable return on its investments, the company recognizes this creates a hardship for some customers.

"We understand that any increase is difficult for some of our customers. That's why we are taking proactive steps to help customers manage their rising energy costs and usage now and in the future," said Baxter.

"We are taking several steps to manage our costs in a disciplined fashion, yet continue to deliver safe and reliable services," he said. "In 2010, we are targeting to reduce our expenditures by nearly $100 million below 2009 levels and approximately $200 million below 2008 levels. In addition, we plan to spend nearly $25 million on energy efficiency programs in 2010 to help our customers reduce their energy usage, and we just announced $5 million in energy assistance programs for our customers who are most in need." Funding for the $5 million in energy assistance programs will come from shareholders and will not be reflected in customers' rates.

UE offers a variety of energy assistance programs to help customers, including weatherization assistance, Budget Billing, the Lighting and Appliance Program, Refrigerator Recycling, HVAC New & Tune Up Program and, soon, Keeping Current (October 2010).

UE's request will be carefully reviewed by the MPSC, staff, and many other parties. This process will take up to 11 months. Unlike other businesses, UE must file a rate request asking to adjust prices to reflect the costs of generating and delivering electricity. Current rates don't reflect its costs and investments. Today, UE residential rates are currently the lowest of any investor-owned utility in Missouri and about 35 percent below the national average.

AmerenUE, founded in 1902, provides electric and gas service to approximately 1.2 million customers across central and eastern Missouri, including the greater St. Louis area. UE serves 57 Missouri counties and 500 towns. For more information, visit www.AmerenUE.com.
