PECO officially announced that David Vahos, the current president and chief executive officer, will transition to a new role as special advisor to the president and CEO of Exelon. This leadership shift represents a significant change for the executive team at Pennsylvania’s largest electric and natural gas utility. Vahos has spent years leading the organization through various infrastructure improvements and service reliability projects. The transition is scheduled to take place over the coming months to ensure organizational stability during the handoff.
Executive Succession and Strategic Planning
Vahos will transition to support Exelon President and CEO Calvin Butler in his new advisory capacity. This move allows the parent corporation to retain his deep operational knowledge while clearing the path for new leadership in Philadelphia. His focus will include high-level strategic projects that affect the broader utility portfolio across multiple states.
Before his time as CEO, Vahos served as the chief financial officer for PECO. This background in finance provided a foundation for managing the utility's complex budget and regulatory filings. His experience with the Pennsylvania Public Utility Commission has been a defining feature of his leadership tenure during a period of rising costs.
The company has not yet named a permanent successor to fill the vacancy left by Vahos. A formal search process is expected to commence immediately to identify a qualified candidate for the position. In the interim, the existing executive leadership team will manage daily operations and maintain service standards for the region.
The board of directors noted that this transition is part of a long-term management development plan. By moving Vahos to an advisory role, the company aims to maintain continuity during a period of industry transformation. This strategy allows for a controlled transfer of responsibilities to the next generation of utility executives.
"David’s leadership at PECO has been defined by a commitment to operational excellence and community engagement. His transition to a special advisor role will provide valuable perspective as we continue to evolve our service delivery across all Exelon utilities."
— Calvin Butler, President and CEO at Exelon

Operational Impact and Regional Service
PECO serves approximately 1.7 million electric customers and more than 500,000 natural gas customers throughout southeastern Pennsylvania. The utility manages an expansive network of transmission lines, substations, and underground gas mains. Under the direction of Vahos, the company prioritized grid hardening efforts to mitigate the impact of severe weather events.
The transition occurs as the energy sector faces increasing pressure to adopt cleaner energy solutions. PECO has been active in deploying smart meter technology and supporting the growth of electric vehicle charging networks. These initiatives are designed to meet state environmental targets and improve energy efficiency for residential and commercial users.
Financial performance at the utility has remained steady throughout recent fiscal cycles. The company continues to execute on multi-year capital investment plans that were approved by state regulators. These investments focus on safety, reliability, and the integration of new technologies into the existing distribution system.
Employees and labor partners were informed of the leadership change earlier today. The company emphasized that its core mission of providing safe and reliable energy remains unchanged during this period. Strategic goals for the upcoming year will likely reflect the priorities established during the previous administration.
The transition of David Vahos to the role of special advisor marks a new chapter for both PECO and its parent company, Exelon. As the search for a new president and CEO begins, the utility will remain focused on its operational commitments to the Greater Philadelphia region. Stakeholders and customers can expect a continued emphasis on grid reliability and safety during this leadership change. This move highlights the ongoing evolution of executive talent within the nation's largest utility holding companies.
