Ameren Proposes Alternatives to EPA Clean Power Plan
Ameren has drafted an alternate approach to the EPAâ€™s Clean Power Plan that the St. Louis-based electric utility says would achieve the same final CO2 emission reduction goals as EPAâ€™s proposal while saving Missouri customers $4 billion in costs and avoiding grid reliability problems related to the premature closure of key coal-fired power plants.
- 2020 Targets: Replace the EPAâ€™s interim target goals beginning in 2020 with a more flexible approach that provides states greater leeway in determining the proper glide path to achieve the agencyâ€™s final GHG goals by 2030.
- Interim Reporting: The EPA should establish enhanced interim reporting requirements by the states to facilitate monitoring and to ensure progress is being made to achieve the final 2030 targets, the white paper says.
- Performance Metrics: Revise the compliance formula to provide credit under the EPAâ€™s rate-based method for retiring, and not replacing, existing coal-fired power plants with fossil generation.
- Graduation Dates: Offer states the flexibility to extend the 2030 deadline “if a clear path to meaningful reductions is evident in a reasonable time frame.”
Under the Ameren GHG strategy, by 2035 Ameren would retire more than 1,800 MW (about one-third) of its coal-fired fleet, add approximately 500 MW of renewable generation, extend the license of its 1,200 MW Callaway Nuclear Energy Center and add a 600 MW natural gas combined-cycle unit, the utility says.
