CEM (Cogeneration and Energy Management) Engineering was established in 2001 by Martin Lensink. Martin decided to create an engineering consulting firm focused primarily on cogeneration and energy management with the goal of providing solutions to the energy and environmental sectors. Martin had worked in the energy sector for 21 years before starting CEM. The most recent 15 years has involved almost exclusively cogeneration projects.
