FERC Staff has requested more information from various Ameren subsidiaries and Dynegy concerning the market power impacts of the proposed acquisition of Ameren Energy Resources by Dynegy.

The proposed transaction would include Dynegy's acquisition of retail supplier Ameren Energy Marketing Company, which also does business as Homefield Energy.

FERC noted that as part of the applicants' horizontal market power analysis, the applicants submitted a study of the simultaneous transmission import limits for both the existing Midcontinent Independent System Operator, Inc. (MISO) market as well as the expanded future MISO market. "Commission staff finds the studies to be incomplete, in that all the 100 kV and above transmission elements in the first-tier areas were not monitored," FERC Staff said, directing the applicants to resubmit the study monitoring all the 100 kV and above transmission elements in the first-tier areas.

Staff also sought more information on wholesale sales contracts for capacity and energy with the Missouri Joint Municipal Electric Commission and the Illinois Municipal Electric Agency.
