Rebecca Valcq, who served as chair of Public Service Commission of Wisconsin and led several state energy offices, was named the next president of Alliant Energy.
Alliant announced David de Leon, President of Alliant, will retire effective July 1, 2026. Rebecca “Becky” Valcq, who served as chair of the PSC between 2019 and 2025, will take his place as company president.
“David’s 39 years of service are a true reflection of his dedication to our customers, communities and employees across Iowa and Wisconsin,” said Lisa Barton, president and CEO of Alliant Energy, in a statement. “Throughout his career, he championed safety, reliability and community partnership, leading with integrity, care and a deep commitment to serving others. We are grateful for his leadership, and the positive, lasting impact he has had on our employees and the customers who depend on us every day. On behalf of the board of directors, we extend our heartfelt gratitude and wish him the very best in his well-earned retirement.”
Valcq began as President of Alliant Energy’s Wisconsin energy company and Vice President of Energy Delivery on January 5, 2026, officials said. She joined Alliant Energy in 2024 as Assistant Vice President of Regulatory Affairs.
In early 2024, Valcq resigned from chair of the PSC after serving for five years. Governor Tony Evers said it was “an honor and pleasure” to work with her. She also led several state offices for energy, broadband, and energy innovation.
Valcq will have overall accountability for Alliant’s performance in the state, officials said. She will oversee Wisconsin-based operations while supporting customer growth. She will also lead operations support and economic development reports across both Iowa and Wisconsin, officials added.
Valcq serves on the board of directors for the Wisconsin Public Utility Institute, the National Utilities Diversity Council and the United Way of Greater Milwaukee and Waukesha County, officials said. She earned a bachelor’s degree in political science and Spanish from Drake University and a Juris Doctor from Marquette University Law School.
