Keeping the Flying Kangaroo Flying Green
BSE has been appointed the consulting engineers for the HV and LV power systems design. The work is associated with integrating the tri-generation plants into the Qantas-owned and operated HV network at the Sydney Airport jet base.
Ausgrid currently supplies power to Sydney Airport at 33kV to both airport zone substations. This is nearing capacity, with the network owned and operated by SACL (Sydney Airport Corporation Limited). Qantas takes supply from the Ausgrid zone substation located on Qantas Drive via four dedicated feeders to Qantas switching station ‘S’. Qantas then owns and operates their own HV network downstream of switching station ‘S’.
The project comprises two tri-generation plants. One jetbase 8.6MW is planned for construction in the existing car park located adjacent to the Qantas Q Catering Building. This plant will comprise of two 4.3MW gas generators. The intention is to augment the existing Qantas HV network between switching station ‘S’ and sub mains to extend the network to the new tri-generation building.
The smaller plant (Terminal 3, 3MW comprising of two 1.5MW gas generators) will connect into either the SACL or the Qantas network at Terminal 3.
The proposed operational times will be concurrent with Ausgrid’s peak and shoulder operational times to reduce costs and more importantly, reduce green house gas emissions by 40%.
Parallel operation will include the consistent import of electricity from Ausgrid’s network. This buffer is maintained to ensure reverse power into the networks do not occur and the generators have time to react to changing loads. Off-peak and excess demand during shoulder and peak consumption will still be obtained traditionally from Ausgrid’s network, while reducing the overall power draw from the authorities mains.
