From Energy Orphan to Modern Marvel: Weizhou's Undersea Transformation
For decades, Weizhou Island's 15,000 residents endured rolling blackouts and the constant rumble of diesel generators on this volcanic landmass in the Beibu Gulf. This year marked a historic turning point as engineers successfully deployed a 44.8-kilometer undersea power cable – weighing as much as 80 freight cars – to connect the island to the Chinese mainland's grid.
The engineering marvel, locally dubbed the 'sea dragon,' required 18 months of precision work to navigate complex seabed terrain. State Grid Corporation technicians used advanced marine positioning systems to lay the 7,000-tonne cable through strong currents and volcanic rock formations.
'This isn't just about lights staying on,' explains project manager Li Wei. 'Reliable electricity enables modern healthcare, water treatment, and eco-tourism development crucial for the island's future.' Early benefits include 24-hour operation of the island's freshwater desalination plant and upgraded port facilities attracting cruise ships.
The infrastructure breakthrough comes as China accelerates rural electrification projects, with Weizhou serving as a test case for challenging marine environments. Energy analysts note the project's success could influence plans for other offshore developments in the South China Sea region.
