China Southern Grid ramps up power line rollout

China Southern Power Grid Co Ltd will add another two major power lines to its east-west electricity network by 2020, which are expected to increase transmission capacity by 55 percent, the company said on Tuesday.

The utility company said as a result the grid will be able to meet an extra power load equal to the combined amount in Guangzhou and Shenzhen, the two biggest cities in southern China's Guangdong province.

The infrastructure rollout is part of a national program to transmit electricity from China's resource-rich west to its energy-thirsty east.
