WALTHAM, MA -- (Marketwired) -- 09/06/17 -- 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 that it has secured an order for 10 InVerde e+ units that will be installed in new residential construction in Brooklyn, NY. With a rated peak generation capacity of over 1 MW, the system is a substantial investment for the buyer. Importantly, these InVerde e+ will be equipped with cloud-based real-time performance monitoring via Tecogen's CHPInsight software.

Abinand Rangesh, Tecogen's Director of Project Development, stated, "These ten units add to Tecogen's market-leading fleet of installed CHP units that it maintains in New York City. Having hundreds of units in such a compact area provides the kind of critical mass that a company like Tecogen needs in order to provide the highest level of customer service to both new and existing customers. Proper servicing ensures that buyers of our equipment are actually able to enjoy the levels of savings and reliability that they expect and demand."

"This new order further solidifies Tecogen's position as the vendor of choice in the CHP market. Over the last five years, our InVerde product line alone has clocked in well over two million hours of service," commented Tecogen's Co-CEO Benjamin Locke. "The order highlights the scalability of our exclusive microgrid technology and a growing awareness of the rock-solid reliability, substantial cost savings, and small environmental footprint that our products consistently deliver to our customers."
