SPOKANE, Wash.--()--Ecova, a leading energy and sustainability management company, today announced Mathias Lelievre as its new president and chief executive officer.

Lelievre brings strategic leadership with global energy industry experience to expand Ecova’s data and technology solutions within today’s dynamic energy market. Lelievre most recently served as the head of ENGIE’s Green Mobility Program, where he harnessed the $400+ million enterprise’s broad capabilities to expand the business’ reach around the world. He also served as the chief of staff for Isabelle Kocher, ENGIE’s president and CEO, with whom he worked hand in hand on the strategy, communication and overall transformation of ENGIE.

“Mathias is a positive force for the convergence of energy and technology to deliver long-term sustainability,” said Frank Demaille, President and CEO of ENGIE North America. “In his new role, Mathias will not only further advance Ecova’s technology-enabled services and solutions, but also foster synergies across ENGIE to deliver more impactful offerings to our clients and expand our services globally.”

Before joining ENGIE, Lelievre served as advisor and then deputy chief of staff of French Minister for Industry and then Economy from 2012 to 2014. In this role he was in charge of the industry, energy and mining sectors.

“I first joined ENGIE because I have a personal passion for energy, sustainability and technology,” said Lelievre. “At the crossroads of technology and energy efficiency, Ecova is a driving force in the energy revolution. I will focus on guiding Ecova through the continued development of our technology and investment in our talent so that we set the pace of innovation for the energy management industry.”
