Tecogen's Exclusive Microgrid Solution to Power Ph

WALTHAM, MA --(Marketwired - July 06, 2017) - Tecogen® Inc. ( NASDAQ : TGEN ) a clean energy company providing ultra-efficient, clean, natural gas powered on-site power, heating and cooling equipment, is pleased to announce the sale of five InVerde e+ combined heat and power (CHP) units to a pharmaceutical company located in the San Francisco Bay, CA area. The 625 kilowatt system will be installed in conjunction with absorption chillers to create a highly efficient natural gas powered tri-generation system that will provide power, heating and cooling to the site's 85,000 square foot corporate headquarters. In addition to administrative offices, the facility will house a state-of-the-art research center and life sciences laboratories that all require critical climate control and emergency standby power.

Speaking about the project, Tecogen's West Coast Vice President of Sales, William Martini commented, "This pharmaceutical company's new corporate headquarters will house the latest in technology-driven clinical research and development equipment, requiring precision climate control and robust emergency standby power systems. Tecogen's local engineering and installation expertise, long-term service presence in the Bay Area, and familiarity with California permitting and emissions regulations all were key factors in the decision to select the InVerde solution."

Benjamin Locke, Tecogen's Co-CEO, added, "Because of the critical nature of their research, our InVerde e+ with its rapid blackstart emergency capability is a natural fit for this customer's needs. With strict requirements for backup redundancy, reserve propane tanks will be kept on site to allow for fuel-switching in case of natural gas supply disruption, lending additional robustness to the CHP system. Importantly, the InVerde e+ uses Tecogen's exclusively licensed CERTS microgrid technology that enables the five units to seamlessly balance demand from the facility and rapidly respond to load changes and outages."
