Capstone Green Energy Names New CEO after Jamison Resignation

Aug. 15, 2023
Robert Flexon, the former Dynergy and Foster & Wheeler CEO who became Capstone’s Executive Chairman a week ago, will step in as interim President and CEO in Jamison’s absence.
Microgrid turbine provider Capstone Green Energy is on the search for a new CEO after the resignation of its current everyday leader effective later this month.

Capstone Green Energy announced Monday that Darren Jamison is stepping down after 16 years at the company. His resignation takes effect on Aug. 22, only a week away.

Robert Flexon, the former Dynergy and Foster & Wheeler CEO who became Capstone’s Executive Chairman a week ago, will step in as interim President and CEO in Jamison’s absence. Jamison also resigned from his board position and CEO role he had held since 2006.

“The board thanks Darren for his 16 years of service at Capstone,” Denise Wilson, lead independent director on the board, said in a statement. “As we support the company and employees during this transition period, we are grateful to be able to tap into Bob’s leadership and industry experience.”

Flexon brings decades of experience in the energy industry from the utility and supplier sectors. He currently is chair of the board at Pacific Gas & Electric’s parent PG&E Corp., while also serving on the board of the directors at the Electric Reliability Council of Texas, that state’s key grid operator.

He led Dynergy Holdings through its bankruptcy filing in 2011, suffering from high levels of debt. The company emerged out of Chapter 11 reorganization one year later and went on to grow and make several acquisitions before itself being acquired by Vistra Corp. in 2018.

Among its products, Capstone Green Energy makes and supplies microturbine systems for microgrids and other on-site power applications. It has supplied gas-fired microturbines for oil and gas operations in the Marcellus Shale, Canada, Texas and Wyoming, as well as microgrids at commercial and industrial facilities in the U.S. and other countries.

Capstone claims it has shipped more than 10,000 units to more than 80 countries, to date.

It also provided microturbines for microgrid projects at a housing project within the U.S. Virgin Islands after various hurricanes in recent years.

Microgrid Knowledge and EnergyTech are focused on the mission critical and large-scale energy users and their sustainability and resiliency goals. These include the commercial and industrial sectors, as well as the military, universities, data centers and microgrids. The C&I sectors together account for close to 30 percent of greenhouse gas emissions in the U.S.

Many large-scale energy users such as Fortune 500 companies, and mission-critical users such as military bases, universities, healthcare facilities, public safety and data centers, shifting their energy priorities to reach net-zero carbon goals within the coming decades. These include plans for renewable energy power purchase agreements, but also on-site resiliency projects such as microgrids, combined heat and power, rooftop solar, energy storage, digitalization and building efficiency upgrades.
