Ted Geisler, a 46-year-old Phoenix native, has been with Arizona Public Service (APS) since 2001, serving in various roles including Chief Information Officer and Chief Financial Officer. Most recently, he has been serving as the President of APS, a position he will retain alongside his new responsibilities at Pinnacle West, the holding company of APS.
Under Guldner’s leadership, Pinnacle West made significant strides towards a carbon-free future and improved customer experience. The company, which serves approximately 1.4 million homes and businesses, has assets valued at about £20 billion.
The leadership change comes at a time of accelerated growth for Pinnacle West. The company projects total sales growth of 4-6% in 2025, significantly higher than the 2.7% average growth from 2021 to 2023. This growth is driven by an expanding retail customer base, expected to increase by 1.5-2.5% annually.
To support this growth, APS has outlined an ambitious capital investment plan. The company’s capital expenditure is set to increase from just over £1.6 billion this year to £2.1 billion by 2027. These investments are crucial for maintaining and expanding the power infrastructure to meet the growing demand.
The transition in leadership also reflects a shift in strategic focus. While Guldner was praised for his vision of a carbon-free future, Geisler is noted for his blend of operational and financial acumen. This change suggests a potential emphasis on financial performance and operational efficiency in the coming years.
