Ameren Asset Transfer

Sierra Club
Completed October 2013

Synapse assessed whether a proposed transfer of five large coal-fired power generation plants from Ameren Corporation to Dynegy Inc. would give Dynegy the ability to exercise market power in ways that would unfairly increase costs of electric power in central and southern Illinois. Specifically, Synapse analyzed whether the applicants adequately accounted for the existence of transmission constraints and projected power plant retirements in their evaluation of potential competitive impacts on electricity markets.
