CV delivered an integrated design, construction, testing and commissioning package encompassing civil, primary and secondary electrical infrastructure. The project combined off-site prefabrication with specialist HV installation, testing and commissioning to support the successful connection of the new generation facility to the distribution network.

Key deliverables:

• Civil, electrical primary and secondary design, including earth grid, oil containment, HV layouts, earthing, lightning protection, protection systems, automation and site communications.
• Civil works including earth grid installation, footing systems, drainage, cable trenches and conduits, transformer slabs, bunding systems, noise suppression enclosures, fire walls and oil containment systems.
• Supply and installation of HV and LV cabling and associated electrical infrastructure.
• Installation of primary and secondary electrical systems, including switching and metering plant, bus systems, cubicles, marshalling kiosks, cabling and fibre termination works.
• Prefabrication and fit-out of the substation in Brisbane, followed by transportation and reassembly in Canberra.
• Factory Acceptance Testing (FAT) and pre-commissioning of the prefabricated substation and associated secondary systems.
• Site Acceptance Testing (SAT), including HV primary injection and integration testing with connected HV plant and secondary systems.
• Network switching and final commissioning to facilitate connection to the supply authority’s overhead distribution network.

• 2 MW generation capacity – Delivery of a new landfill gas-to-energy facility capable of converting captured landfill gas into renewable electricity.
• More than 5,700 homes powered – The facility can generate enough green energy to power more than 5,700 homes, over 1,000 additional homes compared with the previous plant.
• 34,900 MWh annual generation capacity – Four power generators provide capacity to produce approximately 34,900 MWh of renewable electricity each year.
• 120,000 tonnes of emissions reduced annually – Capturing and converting landfill gas into energy helps reduce landfill-related greenhouse gas emissions by approximately 120,000 tonnes each year.
• Resilient project delivery – The project was delivered despite significant challenges and delays associated with bushfires and the COVID-19 pandemic.
