Judging from the rail transportation business in the first half of the power equipment business, the revenue recognition rate is lower than expected. The main reason is that the progress of project construction is slow, and at the same time there is a lack of effective financial support. Representatives such as Guodian Nanrui’s revenue from rail transportation and electrical automation services decreased by approximately 3% year-on-year.
Rail transit construction not only requires transformers, switches and other primary equipment, but also requires a large number of secondary equipment such as rail transit integrated monitoring systems, environmental and electromechanical control systems, power monitoring systems, programmable automation controller (PAC), DC traction protection monitoring Devices, AC protection and monitoring devices, signal control systems, etc. At the same time, in order to protect the power quality, filter equipment is also an important supporting equipment for urban rail transit systems. The investment in electrification equipment accounts for about 20% of the cost of rail transit construction. The project that is approved this time will bring about 140 billion market for electrical equipment, of which the secondary equipment market is about 300-400 billion and the rest is primary equipment.
After the centralized approval of the rail transit, it is determined that the relevant projects of the grid smart grid in the second half of the year will also be an important direction for centralized examination and approval by the National Development and Reform Commission. From the perspective of stable growth, the industrial chain involved in power grid construction involves many industry chains, many sub-industries, and investment. Larger. Increasing grid construction is an important means to hedge the economic downturn.
At present, the large-scale construction of the overall power grid has basically been completed, and the main direction for the future is to build a "strong smart grid." The Development and Reform Commission’s green channel project also mentioned the smart grid and power grid reconstruction projects, and it has also become an important policy indicator. Therefore, it is believed that the smart grid and retrofit projects in the second half of the year are expected to become the focus of the NDRC's approval direction.
