AMEREN CORPORATION
ELECTRIC AND GAS SERVICE TERRITORY
Above: With Ameren's 2003 acquisition of CILCORP Inc., the company's service territory grew to include 49,000 square miles in Missouri and Illinois. In early 2004, Ameren announced an agreement to purchase the stock of Illinois Power.
KILOWATTHOUR SALES
Above: Ameren's diverse sales mix offers more stable and predictable sales, compared to companies with sales concentrated in only one or two customer segments.
FUEL MIX BASED ON GENERATION
Above: Ameren is the 4th largest coal buyer in the nation, providing significant purchasing leverage and more stable pricing relative to other fuel choices.
COMPETITIVE ELECTRIC RATES
Above: Ameren's operating companies' annual average revenue per kilowatthour at June 30, 2003, was consistently below the national average revenue per kilowatthour over the same period. These competitive rates mean that, in total, Ameren companies' average rates were nearly 20 percent below the national average.
