He served as the city engineer in the public power community of Napoleon, Ohio, and in 1995, was named the community’s city manager. In that capacity, Gerken served on the AMP Board of Trustees for four years and chaired the AMP Board committee with oversight over the construction of the 42-MW Belleville Hydroelectric Plant. He joined AMP in 1998 as vice president of business and operations.

Gerken is active in public power leadership and policy development positions on a national level:

  • Previous chair of the Public Power, Inc. Board of Directors, which oversees the APPA Hometown Connections utility services affiliate.
  • Current chair of The Energy Authority (TEA) Board. TEA is a large national public power-owned, nonprofit corporation that provides portfolio management.
  • A frequent presenter at APPA meetings and a leader in public power Joint Action Agency working groups, as well as a presenter on hydro issues at HydroVision and other finance conferences.
  • Testifies before congressional committees and FERC technical conferences on wholesale power market issues.

Gerken received the APPA Harold Kramer-John Preston Personal Service Award in June 2005 and the APPA Alex Radin Distinguished Service Award in June 2012. He was recognized as a finalist for the Platt’s Global Energy CEO of the Year Award in December 2010.

Under Gerken’s direction and vision, AMP has undergone tremendous growth and become a recognized leader in the utility industry. Since 2000:

  • AMP’s membership has grown from 83 members in three states to 135 members in nine states;
  • System peak has increased from approximately 2,100 megawatts (MW) to approximately 3,400 MW;
  • Energy sales have increased from 5.8 million megawatt hours (MWh) to nearly 14 million MWh;
  • Energy sales revenue increased from $231 million to $1.036 billion;
  • All AMP project financing and entity ratings have been in the A category;
  • AMP’s financial strength and strong management have been consistently recognized by rating agencies;
  • AMP has been a public power leader in the issuance of Clean Renewable Energy Bonds ($158.6 million) and Build America Bonds ($2.9 billion);
  • AMP developed the first utility-scale wind farm in Ohio;
  • The generation asset development effort underway by AMP is adding more than 1,400 MW of generation capacity, and AMP’s portfolio is approximately 20 percent renewable;
  • AMP has undertaken the largest development of new run-of-the-river hydroelectric generation in the United States with more than 300 MW at four sites at existing dams on the Ohio River;
  • AMP became the largest equity owner of the 1,600 MW Prairie State Energy Campus, a state-of-the-art mine-mouth coal generating facility in southern Illinois that began full-commercial operation in November 2012;
  • AMP executed an asset purchase agreement with FirstEnergy for the purchase of the Fremont Energy Center, an NGCC facility located in Fremont, Ohio. The purchase was finalized in July 2011 and the plant began commercial operation in January 2012;
  • AMP negotiated a settlement with the USEPA regarding alleged violations of NSR provisions of the Clean Air Act at Richard H. Gorsuch Generating Station. The settlement not only protected participating AMP members from the large fines levied on other utilities, but also provided the incentive for participation in AMP’s energy efficiency program; and
  • AMP launched a robust, multi-state energy efficiency program called Efficiency Smart, which had approximately 120,000 MWh in energy savings in the initial three years of operation.
