Integrated Resource Plan

 

Ameren Missouri's Integrated Resource Plan (IRP) is a 20-year plan that supports cleaner energy in Missouri, including major expansions of solar and wind power. The IRP, which is filed every three years with the Missouri Public Service Commission, examines electric customers' projected long-term energy needs. It also describes our preferred approach to meeting those needs in a cost-effective fashion that maintains system reliability as we move to cleaner and more diverse sources of energy generation. A variety of stakeholders are involved in developing the IRP, including representatives from state agencies, consumer advocates and environmental advocates.


Specifics of our plan include:

  • Significantly expanding renewable generation by adding 400 megawatts (MW) of wind power, 45 MW of solar, 28 MW of hydroelectric and 5 MW of landfill gas
  • Continuing to offer energy efficiency programs to customers through our ActOnEnergy program and adding demand response programs when they are cost-effective
  • Retiring approximately one-third (about 1,800 MW) of Ameren Missouri's current coal-fired generating capacity
  • Reducing emissions of Ameren Missouri's existing coal fleet by continuing to make investments in pollution-control equipment
  • Adding 600 MW of efficient combined-cycle and clean-burning natural gas generation in 2034
  • Constructing a second solar energy center that would be the largest in Missouri

We are committed to accomplishing this transition to cleaner energy in a way that is cost-effective and environmentally responsible while maintaining the reliability our customers expect.
