A 50 kW trigeneration plant producing electricity, heat and chilled water will provide 90% of power at a police station in the town of Fairfield in Connecticut, US.

A Tecogen gas-fired combined heat and power (CHP) system installed on the roof of the Fairfield Police Department was 100% funded with grants and should save the town $50,000 each year, said First Selectman Mike Tetreau at its launch.

Annual fuel and maintenance should total $61,534, while the value of power produced by the CHP system would be $112,184, said Jeffery Glick, Tecogen’s vice-president of sales.

Low emissions from the system also meet current Connecticut Air Quality Standards, he added.

The new plant has an estimated lifespan of more than 30 years.
