In line with these plans, the country is expanding its grid with transmission lines to carry the low-carbon energy from the unpopulated areas where wind and solar farms are built to its megacities. According to some estimates cited by Bloomberg last year, this grid expansion undertaking will take 30 years and cost around $300 billion. Currently, China has 30 ultra-high-voltage transmission lines in operation and is one of only two […]
