Ameren Missouri Integrated Resource Plan
 

2016 Integrated Resource Plan Update

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 and 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.

  

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. This includes converting two units at Meramec Energy Center to natural gas in 2016, and retiring the remaining units at Meramec by the end of 2022 and the Sioux Energy Center by the end of 2033.
         
  • 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. 


Ameren Missouri is focused on adding nearly 500 MW of renewable power generation, which, together with other planned changes to generation resources, would allow us to achieve a 30% reduction in carbon dioxide emissions by 2035, based on 2005 levels. Our planned COemissions reductions by 2035 position the company to address the COreductions proposed in June by the federal Environmental Protection Agency (EPA). The EPA's Clean Power Plan targets a 30% reduction in COemissions from the power sector by 2030. Our IRP allows us to achieve significant reductions in COemissions over a slightly longer time frame but would save our customers an estimated $4 billion.

  

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.

What Is an IRP?

Planning for Missouri's Secure Energy Future
Ameren Missouri is focused on energy planning to ensure that Missouri and its citizens have an abundant, reliable and affordable supply of energy today and for decades to come. We recognize a reliable energy supply is essential to our state's economy and our way of life.

Every three years, Ameren Missouri completes a review and analysis of the options we have to meet present and future energy needs. The results are called our Integrated Resource Plan (IRP).

The IRP describes our projected need for additional electric generation and resource options to meet consumer needs while also balancing reliability, energy efficiency, affordable cost and environmental pressures.

Ameren Missouri understands the importance of these decisions and has engaged the assistance of outside stakeholders in this process. Our hope is that the IRP will spur discussion across the state about the best solutions to meet our energy challenges.
