Solar quotes reported that after a string of large-scale solar approvals leading into the end of the year, the NSW Government has left an announcement of the biggest to last. Reach Solar Energy’s 900MW (AC) Yarrabee Solar Project is to be located approximately 23 kilometres southwest of Narrandera in the Riverina Region of Western NSW and will occupy a footprint of 2,600 hectares. The clean power station will be developed in stages. The full 900MW capacity being developed is contingent on a number of conditions being met, including establishing power purchase agreement/s for the electricity generated and high voltage transmission network capacity being available.

The project will require approximately 3 million solar panels if all stages are completed, which will be mounted on 36,000 single axis tracking systems. 222 inverter stations will be distributed throughout site. A new high voltage substation is to be constructed adjacent to the existing Wagga 330kV to Darlington Point transmission line.

If fully developed, Yarrabee Solar Project is expected to generate just over 2,000 GWh of electricity a year, which is equivalent to the electricity consumption of approximately 335,000 homes.

Also in the plans is a potential 35MW/70MWh energy storage facility located adjacent to the substation. At the time the Environmental Impact Statement was submitted, the likely contender for the battery storage aspect was a Tesla Powerpack based system. Powerpack is what’s used in the Tesla Big Battery (Hornsdale Power Reserve) installation in South Australia. Like Hornsdale, Yarrabee will be able to provide ancillary services to help stabilise the grid.

It’s expected Yarrabee’s first stage of 300MW will take approximately 18 months to construct. Between 150 and 200 construction workers will be on site on any given day during construction, but during peak activities this could jump to 450 workers. Post-construction, 10-15 full-time staff would be required at the site on a daily basis.

The project’s capital investment value has been pegged at USD 956,910,000.
