Renewable Energy 
Finding new ways to power the future 
Developing renewable power sources - that is, energy generated from natural resources such as the sun, wind, water, and biomass fuels - is essential to our plan for the future. We’re determined to find new ways to produce cost-effective, reliable, and clean energy for our customers.

Here are a few ways we’re expanding our renewable resources:

  • Solar farm, 2014
    Adding a new renewable energy center to our energy mix by the end of 2014. With more than 19,000 solar panels, the O'Fallon Renewable Energy Center will generate 5.7 MW of electricity. 
  • Solar initiative 
    Evaluating the effectiveness and efficiencies of various solar power systems in our bi-state area.
  • Landfill gas-electric plant
    Turning landfill waste into methane gas - enough electricity to provide power to 10,000 homes.
  • Wind power
    Adding wind power to our generation portfolio by buying enough energy from Horizon Wind Energy's Pioneer Prairie Wind Farm to serve 26,000 homes.
  • Hydroelectric generation
    Increasing the generation capacity at many of our plants.
  • Education for the next generation
    Providing information about renewable energy, energy efficiency, and sustainability efforts at Ameren through the company's Energy Learning Center.
  • Customer resources 
    Providing options and information for our customers, including renewable energy certificates and net metering for independently owned renewable generation from wind and solar.
