Ameren Supports Renewable Energy 
 
 
As a responsible steward of the environment, Ameren is committed to exploring renewable energy options such as wind, solar, landfill gas, agricultural methane, hydroelectric and other alternative energy sources to generate electricity.
 
Here are a few ways we’re expanding our renewable resources:
 
Trash to Electricity
In July 2012, the Maryland Heights Renewable Energy Center opened, using methane gas from a local landfill to efficiently produce enough power for 10,000 homes.
   
Expanding Solar
  • Ameren Missouri is building the state's largest investor-owned solar energy center in O'Fallon, Mo. Construction begins this spring and the energy center is expected to deliver power to customers by December 2014. Featuring more than 19,000 solar panels, the O'Fallon Renewable Energy Center will generate 5.7 MW of electricity.
     
  • Since 2010, Ameren has been evaluating the effectiveness and efficiencies of various solar power systems in our bi-state area.
     
  • Working with solar industry representatives, industrials and customer advocates, Ameren Missouri agreed to make available $91.9 million in solar rebates. By the first quarter of 2014, virtually the entire rebate fund had been depleted.
  
Hydroelectric Generation
Ameren Missouri operates three hydroelectric energy centers, which account for approximately 4% of our generation.
 
Wind Power
  • Ameren Missouri has added wind power to our generation portfolio, purchasing energy from Horizon Wind Energy’s Pioneer Prairie Wind Farm to serve 26,000 homes.
     
  • Ameren Illinois has purchased or committed to purchase just under 15 million renewable energy credits, plus associated energy. This represents a $750 million-plus investment in renewable energy resources.

It is important to recognize that renewable energy resources alone will not meet our customers’ energy needs. Most renewables, including wind and solar, do not provide a steady supply of power and require back up generation and connectivity to the grid when the sun doesn’t shine and the wind doesn’t blow.

Looking ahead, responsible energy policies in the area of renewable generation must be implemented to ensure that we can continue to deliver dependable power to all of our customers at a fair price.
  
Teaching Future Generations
Located at our St. Louis headquarters, visitors at the Energy Learning Center can see our rooftop solar energy system and learn more about Ameren's commitment to renewable energy and energy efficiency programs.
 
Energy Efficiency Programs
When it comes to saving energy, Ameren offers tools, tips and incentives focused on helping customers take action to manage their use. These resources allow customers to save with efficiency improvements today, and then continue to realize savings long into the future.
