Singapore: The project combines world’s largest PV farm, largest battery, longest undersea HVDC cable for transmitting solar power underneath an ocean via Australia–ASEAN power line.
Australia–ASEAN power line is perhaps the most ambitious renewable energy project to this date. This project would combine the world’s largest solar farm, the largest battery, and longest undersea electricity cable. Sun Cable, a Singapore-based company founded in 2018, is behind the proposed $16 B.
The 10 GW solar farm would cover 121 square km (30,000 acres) in Australia’s sunny Northern Territory. That is the equivalent of 9 million rooftop solar PV panels. The solar farm would be paired with a 30 GWh battery storage facility to enable round-the-clock dispatch of renewable power.
The HVDC electric power cable will also be a major undertaking. The project currently envisions an 800 km overhead power line to transmit 3 GW to Darwin on the northern coast of Australia’s Northern Territory. From there, it would transfer to a 3,700 km 2.2 GW undersea power line to Singapore. Again, for perspective, this would be five times longer than the world’s longest undersea HVDC cable, the 720 km Norway-to-Britain North Sea Link that is scheduled to be online in 2021.
The project is scheduled to come online by the end of 2027.
