Cunderdin 100 MW Solar Project

Sun Brilliance plans to build a 100 MW solar farm east of Perth, which will be the biggest solar farm in West Australia by size, and the biggest to date in Australia by output.

Sun Brilliance solar farm on farming land on the outskirts of Cunderdin, in the middle of the state’s wheat belt, will be built, which mean sit will produce more electricity than Australia’ current biggest solar farm, the 102 MW Nyngan facility in western NSW.


The project was originally envisaged as a 25 MW solar farm, but because of rising prices for wholesale electricity, and large scale renewable energy certificates, and investor interest,it decided to increase the size to 100 MW.

The biggest solar farms in WA to date are the 10 MW Greenough River Solar Farm and the 10.6 MW solar farm at the Degrussa copper mine.

The solar farm will be built on a “merchant basis” – meaning no fixed power purchase contract, and without any additional government grants such as those being allocated by the Australian Renewable Energy Agency.

The projects tacks up commercially without the additional government assistance.

The company has applied to connect to Western Power’s grid, the South-West Inter connected System, via 132 kV transmission line 2 km south of the solar farm, and proposes to build its own 120 MVA,132 kV/22 kV sub-station at the plant site.

The project partners are in final negotiations with several investors for a 30 percent equity investment, and also several lenders for 70 percent debt, with financial closure expected in May 2017. It hopes to begin construction in June and complete it by March 2018.
