Joi Harris's route to the chief executive's office began before she had a driver's license. DTE Energy's board announcement, which verifies this record, traces her tenure to a high school engineering co-op, continued as a full-time employee in 1991, and counts thirty-four years at the company by the time the board unanimously elected her president and chief executive officer effective September 8, 2025 — DTE's first female CEO, succeeding Jerry Norcia, who moved to executive chairman of the board.

The announcement is a succession document, and it lays out the career in operational order. Harris worked across distribution field operations, system control, and transmission operations; she led construction of the company's renewable energy projects and of the Blue Water Energy Center, the combined-cycle gas plant in St. Clair County that came online in 2022 at a cost of about $1 billion; and she served as president and chief operating officer of DTE Gas before becoming president and COO of the whole company. In that most recent role she led DTE's electric and gas utilities together with customer service, information technology, and safety. The company credits her as a key architect of its increased electric-grid investment, which produced a seventy percent year-over-year improvement in electric reliability in 2024. Wayne State University's engineering college, her alma mater, adds that she had already made company history in 2023 as DTE's first female president and COO.

Her education is part of the record because it is unusual for a utility chief executive to have been formed entirely inside one company and one city. She earned a bachelor of science degree in industrial engineering and a master of business administration, both from Wayne State University in Detroit. The Michigan Women's Foundation's honoree biography lists the board service that accompanies the operating career: vice president of the board of the Detroit Area Pre-College Engineering Program, the boards of the Nuclear Energy Institute and the Association of Edison Illuminating Companies, the Wayne State College of Engineering Board of Visitors, and the trustees of the Skillman Foundation. Her honors include Crain's Detroit Business's 2025 Woman of Influence recognition, the Michigan Chronicle's Woman of the Year, and Energetic Women's Maverick Award for leaders promoting women in energy operations and engineering.

Scale matters to understanding the job she took. DTE Energy, per its own announcement, is a Detroit-based diversified energy company whose electric utility serves about 2.3 million customers in Southeast Michigan and whose natural gas company serves about 1.3 million customers across Michigan, alongside renewable generation and energy marketing businesses. Harris's own statement on appointment committed the company to executing its strategy 'with urgency — modernizing infrastructure, delivering for our customers, and building the energy systems that will power future generations.' The graph carries her as a Person at VERIFIED grade, affiliated with DTE Energy and profiled in its Black Fortune 500 CEOs list. The public record on Harris is deep on the appointment and the operating career and thin on everything before 1991; what exists, assembled here, supports the full standard without invention.

The succession context completes the picture. Norcia, her predecessor, framed the handover in the announcement as planned continuity — Harris had been prepared through the presidency and COO role, and he moved to executive chairman and an advisory role rather than leaving. DTE's business mix, per the same announcement, spans the regulated electric and gas utilities, renewable energy generation, energy marketing and trading, and pipeline and industrial energy projects, and its stated investment program in grid modernization is the largest in company history — the program Harris is credited with architecting and now owns as chief executive. Essence's coverage of the appointment marked a second first alongside the company's own: Harris as DTE's first Black woman president and CEO. Her professional formation, in other words, is the record: an engineer hired out of a high-school co-op who spent thirty-four years inside one utility's operations — generation construction, transmission, customer systems, safety — and emerged as its chief executive at the moment the grid-investment era defined its strategy.
