Bergen County Utilities Authority

Utilizing the biogas produced in the wastewater treatment process, Bergen County Utilities Authority retained DCO to design, and construct a combined heat and power plant to provide thermal and electric energy to their wastewater treatment plant in Little Ferry, New Jersey.

• The CHP facility uses the biogas from the adjacent wastewater treatment facility mixed with natural gas to fuel electrical generation equipment with heat recovery steam generators.
• Hot water is produced as a byproduct of generation and is utilized in the waste treatment process.
• The initial project included a total of 2.8 MW of electric generation (two reciprocating engines) and 10 MMBtu/hour of hot water through waste heat recovery units from the engines.

An expansion project was completed in 2015, generating an additional 1.4 MW of electricity and 5 MMBTU/hr Boiler Capacity – Hot Water.
