Australian renewable energy developer Ark Energy has submitted a development application for a 500MW solar-plus-storage project in Myrtle Creek, in north New South Wales, Australia.

The Richmond Valley solar project will incorporate a co-located 275MW/2,200MWh battery energy storage system (BESS), making it amongst the largest connected to the National Electricity Market (NEM), which spans southern and eastern Australia. It is located close to existing transmission infrastructure and has been described as a “great location for solar energy”.

Ark Energy, a subsidiary of Korea Zinc Co, a zinc smelter, confirmed that the BESS would use lithium-iron phosphate (LFP) technology and be eight hours in duration.

On the solar aspect of the project, either crystalline silicon or thin-film technology would be used, mounted on an east-west tracking system. It will consist of up to 730,000 bifacial solar modules.
