Tecogen Ultra-Low Emissions Technology to be Retrofitted to Natural-Gas Water Pump Engine in California


WALTHAM, Mass., Oct. 25, 2012 /PRNewswire/ -- Tecogen Inc. announced today that it is entering into a project sponsored by Southern California Gas Co.(SoCalGas), along with DE Solutions, and the Eastern Municipal Water District (EMWD) to retrofit a natural-gas powered EMWD water pump engine with Tecogen's proprietary ultra-low emissions technology.  This project will be the first demonstration of Tecogen's emission control technology on a non-Tecogen engine, and an important proof of concept for its wider application.

EMWD's water pump engines serve the municipal water supply and must conform to South Coast Air Quality Management District (SCAQMD) regulations for pollutant emissions.  The goal of this project is to significantly reduce the need for the high-level of operator intervention now required to maintain continuous emission compliance. The EMWD project is a 225 horsepower engine in Moreno Valley. The retrofit project includes engineering and installation followed by six months of monitoring to confirm successful results.

"Southern California is home to the strictest air quality standards in the country," said Hal D. Snyder, vice president of customer solutions at SoCalGas. "Developing technology that can help our customers maintain robust compliance to these standards is of paramount importance to us. Our investment in innovative projects like this one helps support the use of clean, low-cost and domestically abundant natural gas."

"The business efforts and costs associated with maintaining the water pump engines within permitted levels is a concern which we hope to significantly minimize with the Tecogen ultra-low emissions retrofit," said Jayne Joy, EMWD director of environmental and regulatory compliance.  "The Tecogen emissions technology will give our engines a much more forgiving control window while maintaining mandated emissions levels including Best Available Control Technology (BACT)."

"We have experienced great success with this technology on our own products and are confident of its transition into other applications," said Robert Panora, president and chief operating officer, Tecogen Inc. "We hope that our participation in this project will help to springboard Tecogen into the retrofit market for many other engine applications."
