Greater Bay Area to see more stable power supply

More measures to guarantee a stable power supply in Guangdong-Hong Kong-Macao Greater Bay Area are in pipeline, said officials from Shenzhen Power Supply Co Ltd, a subsidiary of China's grid major China Southern Power Grid.

Measures include promoting smart grid for more efficient and green power supply in a total of nine cities involved in the Guangdong-Hong Kong-Macao Greater Bay Area.

Take Shenzhen, one of the area's pivots of power transmission and conversion, as an example. The company said it will promote unmanned patrolling and maintenance for its three electrical substations in 2019, alongside other efforts of smart grid promotion.

The company also will set up 65 new power converter stations in Shenzhen, and will optimize power grid structure in battling natural disasters such as typhoon. The goal is to meet the area's increasing demand.

In 2018, power supply in Shenzhen hit 88.9 billion kWh, up 4 percent year-on-year. Power consumption in Shenzhen reached 90.7 billion kWh, a 3.7 percent increase year-on-year.

"Going ahead, Shenzhen will see a big increase in demand," said Cai Jingtao, deputy head for grid planning under department of asset management at Shenzhen Power Supply.

Currently, Shenzhen has a total of 250 power converter stations at 110 KV or above, and 4,856 kilometers of power lines for about 3.12 million clients, including households, factories, and businesses, making the city one of China's most complicated grid networks.
