IIRC a solar farm is being built in Australia which isn't going to touch Australia's own power grid, but rather is going to connect to Singapore's power grid using a pair of undersea HVDC cable runs.

Taiwan could probably get in on that action. If you're already running a 3500km cable, you could run a 4500km cable just as well.

(Kind of annoying that Taiwan can't just buy green energy from China — very easy logistically — but that's extremely politically untenable.)
