According to The Guardian article, "a 10-gigawatt-capacity array of panels will be spread across 15,000 hectares and be backed by battery storage to ensure it can supply power around the clock". To achieve that, the battery storage would have to have a capacity in excess of about 100 GWh. Seeing as the biggest battery in the world only has a capacity of 100 MWh, I hope that would-be investors notice the thousand-fold discrepancy in the salesman's spin before they hand over any cash.

That comes out to 3.2% per 1000 km for undersea HVDC cable. It is impressive when compared to low voltage, AC distribution cables whose planning accepts losses of 5% per 100 km. Long distance, high-voltage AC is better but suffers radiation losses.
I would have thought that a more feasible plan would put HVDC connections between each of the well-populated islands of Indonesia, of which there are many. The majority of these lie on the "Sunda Shelf". The Shelf extends west to Singapore and western Malaysia and east to Bali. It is separated from Australia by a subduction trench along the south and on the east by contorted ocean beds that constitute the Wallace Line.
Indonesia is a world-rank exporter of coal and natural gas. Predictably, there is strong opposition to nuclear. Either way, it would make sense for Indonesia to generate and sell electricity to Singapore, Malaysia and the Philippines through such cables.
