Appointment of Christian Flach as Greenergy Chief Executive and Andrew Owens as Chairman

3rd June 2019

Greenergy today announces that co-founder Andrew Owens is making his planned move from Chief Executive to Non-Executive Chairman following the sale of the business in 2017.

After an 18-month search and selection process, Christian Flach joins Greenergy on 3 June 2019. On 1st September, after an initial transition period, Christian will become Chief Executive and Andrew will become Chairman. All other Executive Directors and senior managers will continue in their existing roles.

Christian joins from Marquard & Bahls, a German family-owned company that trades under the Oiltanking and Mabanaft brands amongst others. With a career spanning over 25 years, Christian has held a range of leadership roles, as leader of several Marquard & Bahls business units and most recently as CEO of the group between 2011 and 2018, and brings considerable experience of the fuel infrastructure and fuel supply sectors.

Andrew Owens said: “After nearly three decades at Greenergy, and having secured new owners for the business in 2017, we began the process of finding a successor to enable me to step back from the day-to-day running of the business.

“Greenergy has great people working throughout the company and is led by a hugely capable and driven Executive team. Christian brings additional strength and depth to the business and is the ideal candidate to work with the existing management team to lead our growth and international expansion in the years ahead.”

The Board and shareholders of Greenergy said: “We would like to thank Andrew for his leadership and contribution to the success of the business. We have worked closely with Andrew over the last 18 months to find a suitable successor, to allow him to fulfil his long-stated preference to move to the role of Chairman. We extend a warm welcome to Christian and look forward to working with both Andrew and Christian in their new roles.”

Christian Flach said: “Greenergy has an amazing track-record, and is a company I have always admired. I very much look forward to working with Andrew and the rest of the team to take the company to the next stage of its development.”
