COFRA’s Clean Energy Group appoints Roger Knubben as Interim Sunrock CEO

Zug, Switzerland, 18 September 2024 – COFRA’s Clean Energy Group announces the appointment of Roger Knubben as Interim CEO of Sunrock – one of Europe’s leading developers of commercial rooftop solar projects. Roger assumes the CEO role on an interim basis on 14 October from Johannes Duijzer, who is stepping down after seven years of service as CEO.

Roger joins from the Port of Rotterdam Authority, where he set up and was Director of the New Energy Taskforce, which identified solutions to network-congestion bottlenecks. He was previously Managing Director of Future Energy Home (Essent/E.ON) and CEO of several technical services firms, including Imtech Benelux.

Jheroen Muste, Executive Chair of COFRA’s Clean Energy Group, said: “Johannes has made an immense contribution at Sunrock as co-founder and CEO. He oversaw Sunrock’s rapid growth, including successful expansion into Germany and France – all while instilling an entrepreneurial, purpose-driven and collaborative culture. He leaves with our best wishes for the future.

As Sunrock’s new Interim CEO, Roger brings decades of proven leadership experience in the energy sector, which will be invaluable as Sunrock looks to drive the energy transition forward as a B Corp certified company. I am confident that he is the right person, at the right time, to lead the next stage of Sunrock’s evolution.”

Johannes Duijzer commented: “Building Sunrock into one of Europe’s main players in commercial rooftop solar has been a huge privilege, only matched by the opportunity to work alongside so many talented and passionate colleagues. However, after co-founding Sunrock twelve years ago and spending seven years as CEO the time is right to hand over to Roger, who, I am sure, will lead Sunrock to even greater heights.”

Roger Knubben, Sunrock’s new Interim CEO, said: “Transitioning to cleaner sources of energy to address climate change, while ensuring security of supply and affordability, is one of society’s greatest challenges. So I am thrilled to join Sunrock as CEO at such a crucial inflection point in the company’s development as we seek to consolidate its leadership position and further increase our positive impact on society and the environment.”
