How can you make ten 3 MWe diesel generators look good?
The Alternate Utility Facility (AUF) is located on an approximately 1.2-acre site on Port of Seattle property (SeaTac Airport) adjacent to 28th Avenue and near the Port’s South Main Substation. It is an alternate electrical energy generating system capable of supplying 30 megawatts (MWe) of power via ten (10) 3 MWe diesel generators. The AUF is capable of soft parallel with the upstream power supplier (PSE) in order to transition to and from the normal power provider, as well as provide power upon unexpected loss of normal utility power. The Project consists of the 10 generators, a Control Building, Medium Voltage (MV) Switchgear building, and MV Automatic Transfer Switching building on a separate secure campus, connected to Seatac Airport’s South Main Substation by MV underground ducts.
