Ted Geisler has been named president of APS.

Phoenix Business Journal

Arizona Public Service Co. will have a new president effective May 16. 

APS parent company Pinnacle West Capital Corp. announced Thursday that Ted Geisler has been promoted to president of the electric utility. It is a move that separates the CEO and president roles within APS. 

Geisler, who began working at APS in 2001, has most recently served as senior vice president and chief financial officer for both Pinnacle West and APS. Andrew Cooper, current vice president and treasurer of APS, will move into Geisler’s former role. 

Geisler and Cooper will both report to Jeff Guldner, who retains the roles of PNW chairman, president and CEO and APS chairman and CEO. 

“Returning to separate CEO and president roles within APS allows us to consolidate our core utility functions, specifically non-nuclear operations, public policy, technology, customer experience and strategy,” Guldner said in a statement. “In turn, this move will enable greater internal and external stakeholder collaboration that ensures we execute our mission to serve more than 1.3 million customers. 

“Ted’s well-rounded utility experience is valued by me and the board,” he continued. “Our company and industry face complex and exciting challenges, and this new structure sets us up to address those challenges with customer-centric solutions and to fulfill our promise to do what’s right for the people and prosperity of our state.” 

Geisler, a Phoenix native, serves on the board of Chicanos Por La Causa and volunteers with Hunkapi Programs, which provides equine therapy to children. 

“APS is a terrific company with a long history of service,” Geisler said in a statement. “I am grateful to Jeff for his confidence and support, and humbled to continue serving our employees, our customers and communities to create a sustainable energy future for Arizona.” 

Cooper first joined Pinnacle West and APS in 2020 as vice president and treasurer after serving as director of corporate finance at Consolidated Edison Company of New York. 

Phoenix-based Pinnacle West, an energy holding company, has consolidated assets of approximately $22 billion, about 6,300 megawatts of generating capacity and nearly 5,900 employees in Arizona and New Mexico. APS, the company’s principal subsidiary, provides retail electricity service to more than 1.3 million Arizona homes and businesses.
