Mary Quaney, former CFO at Mainstream Renewable Power, has become CEO following Andy Kinsella’s resignation.

She has been with the firm since 2009 and joined the board of directors last year.

Mainstream chairman, Eddie O’Connor, Quaney would “lead Main Mainstream through the next phase of our high-growth trajectory”.

He added: “Mary brings significant experience and a record of success that will be critical as we continue to build the company across the world as the transition to renewable energy accelerates. Mary will be supported by our chief operations officer Bart Doyle and the global leadership team.”

The firm thanked Kinsella, CEO since 2016 and previously head of offshore.

“Andy has had a very successful career at Mainstream,” said O’Connor. “The greatest test of any departing CEO is the quality of the management that follows their tenure. Andy brought a passion and commitment to the senior roles he fulfilled at Mainstream. He has left the company in great shape with a very accomplished senior management, led by Mary Quaney, poised to advance further the company’s ambitions. I and our Board are grateful to Andy and wish him every success in all his future endeavours.”
