China’s leading utility company has kicked off a $3.9 billion project aimed at fortifying the nation’s power transmission and storage infrastructure.
This endeavor consists of a 1,069-kilometer ultra-high-voltage power line from Shaanxi province to Hefei, along with a 1.2 gigawatt pumped hydro station using mountain reservoirs at different heights to store the energy. Its aim is to address challenges posed by the escalating use of intermittent renewable energy in China.
