China leads Asian smart grid development

China is leading the Asia Pacific region in the development of smart grid technology according to a new report.

The study from research company GlobalData states that China’s utilization of ultra-high-voltage (UHV) transmission, along with its increasing UHV technology adoption and growing focus on renewable energy sources, is playing a key role in developing robust transmission and distribution infrastructure in the country.

GlobalData senior analyst Siddhartha Raina said: “China decided to invest in UHV transmission in 2004 due to the distant location of energy resource sites from its southern and eastern load centres. This technology was a logical choice for keeping the country’s T&D losses low over such long distances.” smart grid

The country’s fourth largest UHV project, a 1000 kv UHV alternating current transmission project, which starts from Anhui province and extends to East China, became operational last Septembe.

According to the GlobalData report, these projects are part of the State Grid Corporation of China’s plan to invest approximately $75.5bn in the construction of UHV power transmission lines by 2015. Both the SGCC and China Southern Power Grid Company are rapidly utilizing the UHV transmission lines to expand the country’s grid system.

Raina added: “The focus of the Chinese government clearly lies on grid modernization and improving efficiency. The government set a target to interconnect its existing grids and form an integrated synchronous national grid by the end of 2020. This will help to facilitate the efficient transfer of electricity in order to meet growing power demands, as well as demands from the renewable energy sector.”
