He helped lead the deployment of PECO's advanced metering and smart grid technologies, later serving as senior vice president and chief operating officer, where he oversaw operations, safety, reliability, customer satisfaction and financial performance, helping PECO achieve some of its strongest reliability results. As president and CEO from 2018 to 2024, Innocenzo guided PECO through the COVID-19 pandemic, successful regulatory outcomes and significant investments in infrastructure, technology and resiliency. He also championed workforce and community initiatives, including PECO's Energizing Education program, which evolved into today's Exelon STEM Academies. In 2024, he was named Executive Vice President and Chief Operating Officer of Exelon, overseeing operations across the company's six utilities, while also serving as PECO's Interim President and CEO, a role he assumed earlier this year. A respected business and civic leader, Innocenzo was named Citizen of the Year by The Philadelphia Citizen in 2014 and Most Admired CEO by the Philadelphia Business Journal in 2021.
