Current Fuel Cell Projects


Eastern Municipal Water District – Moreno Valley
17040 Kitching St.
Moreno Valley, CA

We recently completed the fuel cell cogeneration facility at the Eastern Municipal Water Districts Waste Water Treatment Plant. This system was designed for a final build out of five 300KW DFC300MA fuel cell power plants. We installed the infrastructure for a total of five 300KW DFC300MA, foundations, electrical and piping for four total units and installed three DFC300MA units. This system was designed to run on natural gas and treated anaerobic digester gas. To clean the gas produced in the plant we installed a gas conditioning system consisting of Siloxane removal vessels (SAG), sulfur removal vessels (H2S) and a compression skid. The cogeneration portion of the project involved the recovery of exhaust heat from the fuel cells, using multiple heat recovery units to produce hot water. The hot water was tied into the plants existing hot water loop to supply heat to the digesters. The electrical interconnection to the plant was made at 480V, and ties into the plants main switchgear feeding the enire plant. Project was completed in March 2009.


Turlock Irrigation District – City of Turlock Waste Water Treatment Plant
901 S. Walnut St.
Turlock, CA

We recently completed the installation of the fuel cell cogeneration system at the City of Turlock’s Waste Water Treatment Plant using one 1200KW DFC1500B FuelCell Energy power plant. We are the first and only contractor in California who has experience installing this latest design from FuelCell Energy. This system was designed to run on both natural gas and treated anaerobic digester gas. To clean the gas produced in the plant we installed a gas conditioning system consisting of Siloxane removal vessels (SAG), sulfur removal vessels (H2S) and a compression skid. The cogeneration portion of this project involved the recovery of exhaust heat using a single heat recovery unit to produce hot water. The hot water loop was tied into the plants existing hot water loop that supply’s heat to the digesters. Electrical interconnection to the plant was made at 12KV, requiring a step up transformer. Project was completed in December 2008.
