6 FAQs about [China grid automation]

Why is China moving from a traditional power grid to a smart grid?

The author analyzes the reasons for China’s moving from a traditional power grid to a smart grid, followed by an introduction of the investment in smart grids in China (Part II); because smart grids are modernized power grids, the general regulatory mechanism over power grids still applies.

Is China promoting smart grid development?

B. Absence of Systematic Policies to Promote Smart Grid Development As discussed in Part III, China has developed several policies to promote smart grids and the increasing investment in smart grids indicates that these policies are on the right track. However, a detailed review of these policies shows that they are far from enough.

What are the challenges faced by smart grid in China?

All the related policies issued in recent years are concerned with solving the issues of deploying renewable energy and energy conservation in the current power system, but are not for the future development of SG. Lack of clear national strategy and integrative policy is the leading obstacle. 5. Strategic planning on smart grid in China

What is China's power grid regulatory mechanism?

Another feature of China’s Power Grid Regulatory Mechanism is that regulatory powers are concentrated in the central government. Unlike in the United States, where division of power between federal government and state governments over electric industry regulation is a key issue, this question does not exist in China.

What is the role of grid companies in China?

Unlike in other countries where government plays a leading role in the development of SG, in China grid companies have more important role. There are only two grid companies in China: SGCC and CSG. These two companies take charge of almost all power transmission, distribution, dispatch, and customers service activities in China.

Does China have a power grid?

In parallel to policy advancement, there are encouraging technical innovations and many pilot projects implemented by the two grid companies in China . The cumulative investment in the construction of power grids accounts for roughly 36.2% of the total investment in the power sector.
