Jacob Williams now Florida Municipal Power CEO and general manager

Jacob Williams, a former executive at Peabody Energy, joined Florida Municipal Power Agency (FMPA) in September as its new General Manger and CEO.

Williams replaced Nicholas Guarriello, who previously announced his plans to retire, on Sept. 12.

“After a thorough search, we are excited to add Jacob’s leadership and talents to the Agency,” said Bill Conrad, FMPA’s Chairman of the Board of Directors. “Jacob demonstrated a keen insight into the business of FMPA, and the Board is confident he will keep FMPA focused on its mission to provide competitively priced, reliable power.”

Williams has 30 years of experience in the utility industry. He most recently served as vice president, generation and Emissions technologies at Peabody Energy in St. Louis. From 2007 to 2015, Williams was vice president, for global energy analytics, leading the global analysis of energy and coal markets for Peabody.

From 2001 to 2007, Williams was Peabody’s vice president, generation development and played a key role in developing the 1,600-MW Prairie State Energy Campus.


Williams has experience providing services to public power utilities. He has served as Peabody’s representative on the Prairie State Board of Directors with the public power and cooperative partners since 2009.

Prior to joining Peabody, Williams held various positions at Alliant Energy (NYSE:LNT) in energy marketing, trading, integrated resource planning, and generation planning, which included working with municipal and joint action agencies.

“I am honored to be selected as FMPA’s next General Manager and CEO,” said Williams. “The Agency is in a good competitive position and has a bright future. I am eager to work with FMPA’s members and staff to make FMPA the preferred power and service provider for municipal electric utilities.”

Williams holds a bachelor’s degree in electrical engineering from the University of Illinois at Urbana-Champaign and a master’s degree in business administration from the University of Wisconsin-Madison.

Williams has spoken at a number of industry conferences, including the PennWell GenForum event organized by GenerationHub.

FMPA’s members performed a nationwide search. Following a request for proposal process, the agency retained an executive search firm that is a nationally known specialist in recruiting for the utilities industry.
