Ameren Energy Resources Company, LLC (AER), the holding company for the merchant generation business of Ameren Corporation (NYSE: AEE), announced today that Steven R. Sullivan, president and CEO of AER, will also assume the role of president of Ameren Energy Marketing Company (AEM). 

Sullivan has served as president and CEO of AER since March of this year. He has been with the company for more than 20 years.

Shawn E. Schukar has been promoted to senior vice president of Trading and Marketing at AEM. He will assume the responsibilities of former AEM president Andrew M. Serri, who left the company in October. Schukar will oversee placement and optimization of AEM assets in the power markets, including strategies associated with market operations, trading and wholesale and retail marketing. Prior to this promotion, he served as vice president of Strategic Initiatives in Corporate Planning for Ameren for three years. Before that, Schukar previously had experience with marketing, trading, plant operations, gas operations and system operations at Ameren and Illinois Power Company, respectively.

“We are fortunate to be able to take advantage of Shawn’s operations and strategic management experience in our merchant generation business,” Sullivan said.

Current director of Business Services and AER Controller, Mark Eacret, is being promoted to vice president in that role. He will report to Sullivan. Eacret has been with the company for 12 years.

“Mark has demonstrated great leadership and management skills during his tenure and has more than 20 years of experience in deregulated wholesale and retail markets,” Sullivan said.

Sullivan added, “I’m confident in the abilities of the entire AEM/AER team. I’ve seen firsthand what our focus and innovation can achieve. These promotions position our merchant business to weather the current economic downturn and will prepare us well for an eventual recovery in power prices.”
