Tecogen Secures Order for Ultera(R) Emission Package Design for California Water District

WALTHAM, MA / ACCESSWIRE / June 5, 2019 / 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 an order from a Southern California water district for the Phase 1 design of an innovative Ultera after-treatment system for two 800-horsepower Caterpillar engines. This effort will involve an inventive scale-up of nearly twice the size of the largest system produced by Tecogen to date. Following the design phase Tecogen will manufacture two complete Ultera kits for use in the District's water pumping system and will be the first Ultera application to an entirely new engine plant. The District completed a thorough evaluation of both natural gas engine and electric motor options and concluded that the gas option was preferable for various reasons including resiliency during grid outages. When the systems are operational, the District is planning to contract with the local Caterpillar dealer to maintain the systems.

"The District has had a very positive experience with Ultera retrofits in the past and is quite confident in maintaining compliance with the strict emissions regulations in the region," said Robert Panora, President and COO. "We were especially pleased that the local Caterpillar dealer is involved and will maintain the engine and emission control systems."

"We are excited to expand our Ultera system product line to accommodate extra-large engines. This should broaden our markets to include higher capacity gensets, CHP, and other engine-powered platforms," said Benjamin Locke, CEO.

Tecogen's Ultera emissions technology is a proprietary emission control system that provides fuel cell-like environmental performance. The technology has been commercially deployed on hundreds of stationary engine systems including Ford, General Motors, Generac, Caterpillar, and more recently on a Mistubushi engine to reduce emissions from forklifts. Tecogen has demonstrated the effectiveness and feasibility of adapting Ultera to gasoline vehicles as described in a 2018 SAE World Congress paper.
