West Side Condo Partners with Tecogen for Energy Supply Resiliency

WALTHAM, MA -- (Marketwired) -- 09/18/17 -- 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 a luxury condominium building located on Manhattan's west side has chosen to install two InVerde e+ combined heat and power (CHP) units. Constructed about a decade ago, the building was hit hard by flood waters due to Superstorm Sandy in 2012. As part of extensive repair work, the building will install the two InVerde e+ units to provide a resilient power supply to protect against future floods and power outages. Additionally, thanks to their efficiency, the units will enable the building and its residents to enjoy significant savings on their monthly energy bills.

Joseph E Gehret, Tecogen's Director of Field Operations, stated, "It is hard to overstate the importance for a large apartment building to be able to keep the elevators in operation, the water running, key areas lit, and sump pumps working during an outage. It's about both comfort and safety. But it's also about value. This installation will enable the building to generate substantial energy-related savings, resulting in a quick return of the capital cost and a positive return on the investment for years to come."

Tecogen's Co-CEO Benjamin Locke, commented, "We are excited about this purchase. Not only does it exhibit that Tecogen's advanced CHP technology is a significant money saver for customers, but also that its patented black-start and microgrid technology are able to deliver peace-of-mind in a period of growing unease about grid reliability due to aging infrastructure and potential adverse impacts of climate change."
