A Greenwich-based energy-as-a-service provider that develops and operates on-site power generation systems for critical infrastructure facilities has appointed a new CEO while shifting its co-founders into new leadership roles.
Unison Energy has named Mariko McDonagh Meier as CEO. Co-founders Andy Cooper and Tim Lukes, who previously served as co-CEOs, will remain with the company as executive chairman and president, respectively.
Meier joins Unison from Convergent Energy and Power, where she served as chief revenue officer for three years. She previously held several senior management roles at Enel X, formerly EnerNOC, from 2013 to 2020.
Unison said Meier has two decades of experience in the energy and utility space and specializes in scaling energy-as-a-service businesses. Her career also includes roles at McKinsey & Co. and Southern California Edison’s Strategic Projects group. She has worked in the energy industry since 2008.
Meier is a graduate of Stanford University and holds an MBA from Harvard Business School.
Founded in 2013, Unison develops, owns and operates microgrid systems that deliver electricity and thermal energy to critical infrastructure facilities across the U.S., including data centers, industrial facilities, logistics terminals, hospitals, and hotel and convention centers.
Tiger Infrastructure Partners, a New York-based growth infrastructure private equity firm, backed Unison in 2024. Marc Blair, Tiger Infrastructure Partners’ COO, serves as Unison Energy’s chairman.
