Melbourne Airport solar project

Melbourne Airport

Location Tullamarine, Victoria
System Size 12.2MWp PV
1.78MWp Rooftop PV
Key Equipment Trina and Jinko Modules, SMA MVPS and ABB Inverters, S-Rack and Cleanergy Racking

Design and construction of multiple renewable energy projects at Melbourne Airport in Tullamarine, including a fixed tilt solar farm and a rooftop solar PV system with MV inverter and high voltage ring main unit at the Agility Logistics warehouse.

Key outcomes

  • The solar farm is designed to offset 15% of Melbourne Airport’s electricity consumption and power all four passenger terminals at full output.
  • The Agility warehouse rooftop connects to APAM’s 22kV ring feeder, extending the airport’s ability to offset its loads with renewable generation.
  • Delivered works within a fully operational airport environment, with no disruption to operations and no safety impacts to facility personnel or the public.
Casella Wines solar farm

Casella Wines

Location Yenda, New South Wales
System Size 5.7MWp PV
Key Equipment Trina Solar Vanguard 2P Modules, SMA Sunny Central Inverter

Design and construction of a single-axis tracking solar farm at Casella Wines, Yenda NSW. Scope included full HV works to install a 3km, 33kV underground HV cable.

Key outcomes

  • Facilitated the Essential Energy network connection and managed the end-to-end grid connection process. This included network design approvals and energisation across Casella’s private 33kV network and the Essential Energy distribution network.
  • One of the largest ground-mount solar farms installed for an Australian winery.
  • First Trina Vanguard 2P tracking system installed in Australia.
  • All civils, mechanical build, panelling and DC/AC electrical works were completed on time and to budget.
Iluka Resources solar farm

Iluka Resources

Location Cataby, Western Australia
System Size 9.5MWp PV
Key Equipment SMA MVPS, Nextracker, Trina Modules

Design and construction of a single-axis tracking solar farm at Iluka Resources’ Cataby mine site in Western Australia, approximately two hours north of Perth.

Key outcomes

  • Part of a 10-year Power Purchase Agreement to provide ongoing on-site renewable power to Iluka’s Cataby mine facilities.
  • Bespoke civil installation methodology developed to overcome highly sandy soils, including benching of trenches and water soaking to stabilise trench walls.
  • Integrated with an existing operational mine facility, ensuring the design and installation methodology complied with Iluka’s detailed OHS and installation specifications.
