The board of Mainstream Renewable Power has appointed Mary Quaney as group chief executive with immediate effect.
The appointment follows the resignation of Andy Kinsella who has served as chief executive since 2016.
Quaney joined Mainstream in 2009 and has held the role of group chief financial officer since 2017.
She was appointed to Mainstream’s board of directors in 2019.
Mainstream chairman Eddie O’Connor said: “I’m delighted to announce the appointment of Mary Quaney to lead Mainstream through the next phase of our high-growth trajectory.
“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 that is so admired within the industry.”
O’Connor said the board “wishes to acknowledge the contribution” of Kinsella.
O’Connor added: “Andy has had a very successful career at Mainstream.
“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.”
