King County WTD - South Treatment Cogeneration Plant

South TreatmentDescription of Project
This project includes construction of a new eight-megawatt cogeneration facility at King County's south treatment plant in Renton, Washington. Cogeneration is the simultaneous production of heat and electricity utilizing digestor gas and/or natural gas. This facility is being constructed to augment the existing electrical power supply and replace the existing heating system at the plant with a more efficient and economical system. Heat recovered from the cogeneration facility will be used to meet south plant's space and process heating requirements. The entire facility will be housed in a new 100' x 150' steel frame building with precast concrete panel walls.

Technology
The cogeneration plant will consist of two gas turbine generators (GTG), two heat recovery steam generators (HRSG), one steam turbine generator (STG), three steam-water heaters for treatment plant space and process heat loads, and all ancillary equipment.
