The standby power system at the Nitinat Hatchery consisted of three diesel generators located in a separate powerhouse at the remote site. The existing generator sets are cooled by remote radiators mounted on the roof of the powerhouse. The engine exhaust silencers are also roof mounted. The existing sets had difficulty handling low load conditions and were approaching the end of their service life.
Water Street completed the mechanical design to replace the existing generator sets with three new 200 kW generator sets and associated external roof-mount radiators including cooling and exhaust piping and anchoring of the sets. The project was led by PBX Engineering who also completed the electrical design for the project.
