SPECIAL FEATURES: 27MW output and Biomass methane fired


Klickitat PUD Biomass Plant


The power plant previously had five reciprocating piston engines to generate up to 27MW. JH Kelly added two landfill gas (LFG) fueled combustion turbine generators (CTGs), two heat recovery steam generators (HRSG) and one steam turbine and generator (SRG).

The CTGs are rated at 10.2 MW nominal output each and the HRSGs are rated at 32,800 pound/hour of steam each at 650 psi and 750 degrees farenheit. The STG is rated at 6 MW nominal output and receives the total steam flow from both HRSGs. The STG exhausts to the Air Cooled Condenser (ACC).

The project also added a state of the art cleaning and compression facility which cleans the “dirty” landfill gas to a level better than natural gas and prepares it for efficient use in the CTGs.

JH Kelly was the General Contractor for the project and self-performed a majority of the work including: all mechanical equipment installation (including turbine assembly); piping installation; fire suppression systems; water treatment; electrical and instrumentation.
