Kohort Energy was founded to serve as a reliable partner in energy efficiency consulting for public and private sector organizations, including school districts, restaurants, manufacturers, grocery and convenience stores, and commercial property managers. Central to the formation of the company was the initiation of a partnership with British Energy Saving Technology (BEST), a manufacturer of innovative energy efficiency equipment and cloud-based software headquartered in Cornwall, England. Kohort Energy implements BEST applications and other programs to help clients monitor, control and reduce energy usage, allowing them to monetize future energy savings and reinvest in what matters most. The directors of the firm draw on more than 50 years of combined experience in B2B consulting, mechanical and electrical engineering, electric utility management, and private sector and non-profit leadership.
