At present, power grid construction has become the main direction of China's power construction, and the prospect of power grid construction is attractive. On July 31, 2015, the National Energy Commission announced the notice of the action plan for the construction and transformation of distribution network, pointing out that the investment in the construction and transformation of distribution network will not be less than 2 trillion yuan in the six years from 2015 to 2020. According to the development goal of State Grid Corporation of China, by 2020, a strong smart grid will be built in an all-round way. The intelligent level of power grid will lead the world, and the dispatching and operation of large power grid will reach the international advanced level.
For a long time, the investment ratio between power grid and power supply in major developed countries in the world is generally about 6:4. The proportion of China's power grid investment has increased rapidly. In 2016, China's power grid construction investment accounted for 61.28% of the power engineering investment, and the gap was narrowed compared with developed countries.
From 2009 to 2016, the scale of power transformer market gradually expanded. Based on the analysis of the data in recent years, it is found that the sales revenue of China's power transformer manufacturing industry shows an increasing trend from 2009 to 2016. In 2015, the sales revenue was 270.315 billion yuan, with a year-on-year increase of 8.90%. In 2016, the sales revenue was 291.94 billion yuan, with a year-on-year increase of 8.00%.
At present, China's smart grid has entered an important stage of comprehensive construction, the intelligent construction of urban and rural distribution network will be fully opened, smart grid and intelligent complete sets of equipment, intelligent distribution, control system will usher in the golden development period. This undoubtedly provides a good growth space for the transformer manufacturing industry.
According to the development plan of China's electric power industry and the historical development law of transformers, the analysis report on market demand forecast and investment strategic planning of transformer manufacturing industry released by the authority of forward looking Industry Research Institute predicts that in 2023, the output of transformers in China will reach 2.16 billion KVA, and the market scale of transformer manufacturing industry is expected to reach 750 billion yuan.
During the 13th Five Year Plan period, the State Grid will invest about 2 trillion yuan in power grid construction. According to the data of the National Energy Commission, during the 12th Five Year Plan period (2011-15), the investment of the whole power grid infrastructure was 368.2 billion yuan (58.4 billion US dollars) in 2011 and 411.8 billion yuan (65.4 billion US dollars) in 2014, that is, the average investment of 400 billion yuan (63.5 billion US dollars) per year in 2011-14.
If China's investment in grid infrastructure remains at this rate during the 13th Five Year Plan period, 300 billion yuan (US $47.6 billion) of investment in distribution network will account for 75% of China's total investment in power grid. Under the background that the state is ready to vigorously support distributed generation, especially renewable energy power generation, this measure is of great significance.
