Landfill Gas Powers a Cogeneration System

A Fortune 100 beverage client engaged Woodard & Curran to be part of the team to identify an opportunity to collect gas from a nearby-decommissioned landfill and convert the methane into energy. We were then hired to provide a feasibility study and engineering design for a cogeneration system to produce electricity, heat energy, and chill water, which helped the client achieve its two-pronged goal of creating a process that is financially intelligent and environmentally conscious.

Woodard & Curran was part of a multi-discipline project team that worked with the client to design, engineer, and oversee the construction of a 6.6-MW combined heat and power (CHP) system. To begin, the design team reviewed the facility’s current energy consumption and outlined future potential patterns to determine facility demands. The analysis included a supply-demand capacity analysis showing chilled water demands. The team also analyzed potential equipment solutions and determined a reciprocating engine would be the most effective method of providing energy to the facility.


The CHP system includes three industrial size engines, each capable of producing 2.2 MWs of electricity to offset the process load energy required for an on-site plastic molding process. In addition, three large heat recovery steam generators take engine exhaust gas from the CHP system to generate steam. This steam is then piped into the facility for facility process HVAC use. The steam is also piped to a steam-driven turbine chiller, which cools water used in facility process and the HVAC system.
