                          the goal of having 25 percent of each generation portfolio come from renewables by the
                          year 2025; 75 percent of those renewables must come from wind energy. Renewables can be

                          purchased so long as the impact on energy costs to consumers does not exceed an increase of
                          .5 percent per year annually between 2008 and 2011.

Educating the Next Generation About Renewables
The company and The National Theatre for Children (NTC) have been bringing a live theatrical show to hundreds of schools
across Missouri. Offered to educators free of charge on a first-come, first-served basis, the 25-minute interactive program
delivers important messages of energy conservation and renewable energy as it entertains children in grades K-6. Educators
are encouraged to call NTC at 800-858-3999, ext. 1, to request a performance.

Turning Methane into Megawatts
AmerenUE announced in September 2009 an agreement with Fred Weber, Inc. that includes plans to install combustion
turbines capable of generating about 15 MWs of electricity by burning methane gas at Fred Weber’s Maryland Heights, Mo.,
solid waste landfill. Expected to be operational in 2011, the “Methane to Megawatts” project will be the largest landfill gas-
electric plant in Missouri and among the largest landfill generation plants in the country in terms of generating capacity,
producing enough electricity to meet the demands of about 10,000 homes. Under the terms of the agreement, the company
will purchase the methane from Fred Weber. Methane and other gases are the natural byproducts of the decomposition of
waste in the landfill. The gas is collected through 120 landfill wells, which are plumbed and connected with two miles of high-
density plastic pipe. The methane then will be delivered to the turbines through a blower plant that delivers 6,000 cubic feet
of landfill gas per minute, 24 hours a day. The company is conducting engineering studies to determine the best location on
Fred Weber’s property to place the turbines. Construction of the turbines is expected to begin in 2010, and the turbines are
expected to begin generating power sometime in 2011.

Offering Options to Customers
Responding to customer interest in promoting renewable energy use, AmerenUE launched Pure Power™ in 2007 –– a
voluntary renewable energy credit (REC) program for Missouri residential and business customers. Pure Power allows
residential customers to voluntarily pay an additional 1.5 cents per kilowatthour (kWh) to purchase RECs to encourage
development of renewable resources. Residential customers, as well as small, medium and large business customers, can
also participate by purchasing 1,000 kWh “blocks” of Pure Power for $15 per block. The United States Department of Energy
(DOE) named the company’s Pure Power™ program the “most successful” New Green Power Program of the year in the fall
of 2008. DOE along with the U.S. Environmental Protection Agency (EPA) and the Center for Resource Solutions (CRS) cited
Pure Power as one of the largest green-pricing programs in the Midwest with its more than 4,000 customers.
   In the summer of 2009, the CRS again recognized the company for having the “Best Marketing Campaign by a Green Power
Supplier.” The award was presented as part of the 2009 Green Power Leadership Awards ceremony, organized by the DOE, the
U.S. EPA and the CRS. The award recognizes Pure Power’s “P.U.R.E.* (People Using Renewable Energy) Genius” campaign,
which featured “real people” and their personal reasons for supporting Pure Power.
   Beginning Jan. 1, 2010, in Missouri, the company is offering a rebate of $2 per watt up to 25 kilowatts or a maximum
of $50,000 for qualified new installations (post 1/1/2010) of solar electric systems on residential and commercial
properties. Go to after Jan. 1, 2010, for more information.

Researching Renewables
Over the past two decades, the company has researched wind and solar resources, joining with other utilities and academic
experts to determine the technical and economic viability of potential wind and solar sites in Missouri and Illinois. More
recently, the company has funded internal studies on the feasibility of using a blend of coal and biomass fuels to produce
electricity (biomass energy comes from vegetation, animal wastes and landfill gas). Studies have also been undertaken
related to anaerobic digester systems. Today, through the joint state and federal Tall Towers Program, the company is working
with other Missouri and Illinois electric utilities to determine this region’s potential for the next generation wind turbines.

Increasing Capacity
AmerenUE has increased hydroelectric generation capacity through upgrades at our Osage Plant near the Lake of the Ozarks
in Missouri (online in 1931) and Keokuk Plant in Iowa (online in 1913). Plans are to increase capacity even more at those
plants in the future.

Incorporating Renewables in Future Generation Plans
The company has a robust plan for incorporating renewables into its overall power generation mix — with continued and
detailed assessments of prospective regional renewable resources, like hydroelectric, landfill gas, anaerobic digesters
plus generation from biomass and wind. Once the regional resources with the most technical and economic potential are
identified, then the company will implement a plan for development. The company will continue to utilize a mix of various
generation resources to ensure least-cost, reliable energy to our customers.

Dealing with Challenges Related to Renewables
Across the U.S., development of renewable energy faces regulatory hurdles and resource issues because of the need for large
amounts of land and reliance on intermittent natural resources — like wind — that are not reliable for electrical generation
purposes. A major issue for renewables is the overall lack of transmission infrastructure to bring wind energy from high wind
areas (usually where few people live) to places in and around Missouri and Illinois where wind is not as prevalent and to
cities where electricity demand is greatest. The company filed an Integrated Resource Plan on Feb. 5, 2008, offering more
detailed analysis of the impact of these risk factors.
