The SunCable project is a challenge for sure. No one knows whether it will be successful in its current form.
However it is quite important for the industry as it is pushing the boundaries of current engineering. lf they can make it work it will no doubt be replicated around the world.
Unlike some other posters that are just waffling
here's some more information about the industry.
Sun Cable is experiencing some serious local competition. There appear to be many side benefits for lndonesia however that project faces many significant hurdles also.
New giga-scale contender emerges in race to export solar to Singapore https://reneweconomy.com.au/new-giga-scale-contender-emerges-in-race-to-export-solar-to-singapore/ Some really interesting reading here:
" The Domestic Market Obligation and Domestic Price Obligation for coal producers is a means of subsidising coal-fired power generation. Even though most of the burden is borne by the coal producers, the Government does not receive the tax revenue that would have been created if it was sold at the market price. Solar power production does not enjoy such subsidies as there are no costs related to producing solar power energy that is not directly covered. Unfortunately,the opposite policy has been put in place by the Government, whereby solar generation is penalised through a tariff cap of 75% of the cost of generation, predominantly from the already subsidised tariffs paid to fossil fuel generators from sources such as coal. "
" The key point to note on this issue is that there are no opportunities within the Riau Archipelagoor Indonesia to install and operate more than GWs of solar PV in the next decade
