Suncase cable channels11/13/2022 ![]() And the price tag could also fall between now and then, as the cost of solar panels and other building blocks continues to drop.The performance of parabolic trough based solar power plants over the last 25 years has proven that this technology is an excellent alternative for the commercial power industry. This means the 2030 estimates for Singapore’s 20% reduction in natural gas power would take effect almost right away, not gradually. (There’s no mention of cost on the Sun Cable website.)Ĭonstruction is slated to begin now, with completion in 2027. For Australia and Singapore, the 2,400-mile cable would cost an estimated 2.8 billion to 20.7 billion using the EIA numbers. Energy Information Administration (EIA) places the cost of HVDC cable at “between $1.17 million per mile and $8.62 million per mile” in 2017 dollars, depending on “power capacity to be transmitted, type of transmission medium (submarine or land‐based), environmental considerations, access to easements rights‐of‐way (ROWs), and cost of converter stations and associated equipment.”Ĭhina’s HVDC pipeline carries up to 12 gigawatts over a slightly shorter distance, but it was built by the state and the costs are mysterious. Reverse Solar Panels Could Generate Power at Night.Elon Musk's Trillion-Dollar Energy Future.The $1 Billion Solar Plant Is an Expensive Flop.And yes, replacing 20 percent of Singapore’s grid with solar power sounds great. Everything we do that circles the world is because of these cables. If this sounds like pure science fiction, remember that telecommunications around the world have used deep sea cables for more than a century and a half. Of course, the wildcard in this setup isn’t the solar panels-it’s the 2,400-mile cable that runs at the bottom of the ocean. That’s 3,000 megawatts, which puts the array and pipeline on par with nuclear power plants around the world. In total, the 15,000 hectares (about 58 square miles) of solar panels will deliver 3 gigawatts of power. The developers say these panels will be modular, easy to install, and low risk compared to panels that are more involved to install. With an extremely low population, there’s plenty of room to spread out and build solar panels. The Australian sunshine seaway is a little bit different, as one trunk connecting two far-apart land masses: Australia’s sparsely inhabited Northern Territory and the dense, import-only energy grid of island Singapore.Īustralia’s far Northern Territory shares a sunny, savanna climate with parts of the Amazon Rainforest and the tropical jungles of southeast Asia. Europe’s system carries wind power among other sources, and combining as much capacity as possible into as few low-loss cables as possible means less infrastructure and lower power waste.Įurope aims to make HVDC a huge part of its whole grid, requiring specialized additional technology to make sure the power can be redistributed at its destination. The high voltage direct current (HVDC) cable, in its extra-long format, is in use in China and in Europe as part of those countries’ existing power grids. If this sounds wild, it’s modeled after existing technology that’s already in use in similar contexts. The idea is to pipe renewable solar energy through an undersea cable from Australia’s largely empty Northern Territory. The Sun Cable is privately developed, with estimated completion in 2027.Įntrepreneurs in Australia have an ambitious new plan they claim could provide enough electricity to replace 20 percent of the existing grid of Singapore.Undersea cables already deliver all the world's telecommunications.The Sun Cable is a 2,400-mile undersea cable that delivers solar power from Australia to Singapore. ![]()
