Ameren Missouri, a subsidiary of Ameren Corporation (NYSE: AEE), filed a 20-year plan with the Missouri Public Service Commission to expand solar and wind power in the state.
The utility's "Integrated Resource Plan (IRP)" calls for transitioning its generation fleet to a cleaner and more diverse portfolio over the next two decades.
"The plan we have developed and are executing on also calls for preserving energy efficiency programs that help residents and businesses save money, because the cost of saving a kilowatt-hour of electricity is generally less expensive than the cost of generating it from a new resource," said Michael Moehn, chairman, president and CEO of Ameren Missouri.
The utility plans to add approximately 500-MW of renewable power generation, which, when combined with other planned changes to its generation resources, would allow the utility to achieve a 30 percent reduction in carbon dioxide emissions by 2035, based on 2005 levels, addressing the U.S. Environmental Protection Agency (EPA)'s Clean Power Plan.
Key points of the plan include:
- Adding 400-MW of wind power, 45-MW of solar, 28-MW of hydropower and 5-MW of landfill gas;
- Retire approximately one-third, about 1,800-MW, of the utility's coal-fired generating capacity, including 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;
- Invest in pollution-control equipment at its current coal-fired power plants;
- Add 600-MW of efficient combined-cycle and clean-burning natural gas generation in 2034; and
- Construct the largest solar power project in the state in 2016.
