Ark Energy reaches AU$1.3 billion FID for Richmond Valley solar-plus-storage project

The FID was approved by Korea Zinc’s board on July 21, 2026, for Ark Energy’s Richmond Valley project. The financing package includes AU$586 million in equity and AU$716 million in debt for a project configured with 435 MW of solar PV and 475 MW / 3,148 MWh of battery storage. The scale is significant for Australia because long-duration co-located storage can firm solar output and support grid reliability in a high-renewables market.
