Over his career at Alliant Energy, he has held leadership roles in engineering, energy delivery and generation operations. He was named CEO and Chair of Alliant Energy Corporation, effective July 1, 2019.

In 2010, John was named Senior Vice President – Generation. At that time, he also became President of Wisconsin Power and Light Company. In 2015, John stepped into a new expansive role: leading efforts related to technology, development, generation construction, economic development, customer service and account management.

In recognition of his leadership and accomplishments, in 2017, John was named President of Alliant Energy Corporation. As President, John had critical responsibilities – including leading technology and strategic planning functions – to help the company respond more rapidly to opportunities and deliver greater value to customers.

In 2018, John was named President and Chief Operating Officer of Alliant Energy. In this role, John led the development of the company’s strategy to more clearly understand customer unmet needs. This led to the development of new products, services and markets to deliver long-term value for the communities served by the corporation. Under John’s leadership as CEO, two acquisitions were made and successfully integrated into the non-regulated businesses of the company. Within his first year as CEO, John navigated the organization, delivering strong financial and operational performance, through the unparalleled events of 2020 including the COVID-19 pandemic and the derecho storm, one of the worst storms in the company’s history.

John’s leadership across these roles influenced the development of the company’s vision of advancing a clean energy future that promotes environmental stewardship. Since 2005, Alliant Energy has reduced carbon dioxide emissions by 35% and plans to reduce emissions 50% by 2030, while setting an aspirational goal to achieve net-zero emissions from the electricity the company generates by 2050. This transition will ensure customers have access to a more resilient energy grid and a diverse, sustainable energy mix.

John is a strong advocate of programs and fostering community vitality through diversity and economic development. John is an active member of the Business Roundtable, serving on the Racial Equity and Justice subcommittee for Education and Workforce. He is a signatory of the PwC CEO Action for Diversity and Inclusion pledge. He serves as a board member of the Greater Madison Chamber of Commerce and was a past Board Member for Madison Area Regional Economic Partnership and Junior Achievement of Wisconsin.
