Williamsdale Solar Farm, ACT

  • Location: 20km south east of Canberra, ACT.

  • Size: 11MW

  • Expected Annual Electricity Production, First Year: 21,901 MW hours

  • Expected Annual Tonnes CO2-e Abatement:17,250

  • Expected to power the equivalent of: 3,300 homes

The Williamsdale Solar Farm

The Williamsdale solar farm has more than 30 hectares of solar panels, mounted on a tracking system that keeps the panels facing the sun as it moves throughout the day, resulting in efficiency gains up up to 40% over fixed panel designs.

The solar farm was formerly known as the OneSun Capital Solar Farm, won a Large Scale Feed-in-tariff entitlement in the ACT’s Solar Auction process in 2013. IIG contracted German solar farm construction specialists IB Vogt GmbH, to build the farm. It is due for completion in March 2017. The farm is contracted to receive payment from the ACT’s electricity distributor for a period of 20 years, in accordance with the large-scale and medium-scale Feed-in-Tariff schemes.


Mount Majura Solar Farm, ACT

  • Location: 8km north east of Canberra, ACT.

  • Size: 2.3MW

  • Expected Annual Electricity Production, First Year: 4,269 MW hours

  • Expected Annual Tonnes CO2-e Abatement: 3,726

  • Expected to power the equivalent of: 714 homes

The Mt Majura Solar Farm

Mount Majura Solar Farm includes 7,340 panels mounted on a single-axis tracking system. It was opened in October 2016. The farm is connected to the ACT grid, and is contracted to receive payment from the ACT’s electricity distributor for a period of 20 years, in accordance with the medium-scale Feed-in-Tariff scheme.


Karratha Solar Farm, WA

  • Location: Karratha Airport, WA.

  • Size: 1MW

  • Expected Annual Electricity Production, First Year: 1,824 MW hours

  • Expected Annual Tonnes CO2-e Abatement: 877

  • Expected to power the equivalent of: 392 homes, (although all power will be used by the airport)

The Karratha Solar Farm

The solar farm features cloud prediction technology (CPT) designed to smooth out power generation from the facility. It also reduces the necessary battery capacity and therefore costs. The CPT at the Karratha Solar Farm tracks cloud movements and predicts when they will block the sun’s energy from hitting the panels and cause a sudden drop in the power output. The CPT avoids this by gradually reducing electricity output, allowing the solar farm to meet its obligations to the grid. It has saved more than 20% in battery storage, significantly reducing construction cost and resource consumption. The system includes an all-sky camera, irradiance sensor and data analytics system.

All electricity generated at the Karratha solar farm will be acquired by the City of Karratha, for use at the Karratha Airport, in accordance with a power purchase agreement with a 21 year term and an option (at the election of the Fund) to extend by a further 10 years.

Yulara Solar Project, Northern Territory

In August 2015, IIG provided mezzanine funding to construct 1.8MW of PV solar systems with a 20 year operating lease to Voyages Indigenous Tourism Australia Pty Ltd, a subsidiary of the Indigenous Land Corporation (owned by the Commonwealth of Australia). It is serviced by power purchase agreement cashflows from Epuron’s 5MW portfolio of 5 solar projects, all located within the Northern Territory.


Uterne Solar Projects, Northern Territory

In September 2014, IIG provided mezzanine funding to construct a 5.1MW portfolio of solar projects in the Northern Territory. The Uterne Facility is serviced by power purchase agreement cashflows from Epuron’s 5MW portfolio of 5 solar projects, all located within the Northern Territory. The facility is expected to generate power for the equivalent of 1,503 average households and will displace carbon-intensive energy sources (gas grid supply and remote diesel generators). This energy generated equates to 4,500 tonnes of CO2e abatement.
