In 2017, the supply and demand of electric power will remain loose. The state will prevent and defuse the risk of overcapacity in coal and electric power, continue to promote green development of electric power, substantially reduce investment in power supply, and continue to optimize the structure.Major power enterprises nationwide invested 2,900 yuan in the construction of power supply projects, the lowest since 2011, down 14.9 percent year on year.In addition, China's power investment concentration is also improving, 10 provinces accounted for 66% of China's investment.

Power investment has declined to varying degrees

In terms of types, compared with the previous year, except for the year-on-year growth of 18.2% in the investment in solar power generation and slightly higher investment in hydropower, the investment in thermal power and wind power both dropped sharply.

Hydropower investment was basically unchanged from the previous year, and pumped storage investment hit a record high

Affected by the difficulties and rising costs of hydropower development in southwest China, as well as the prominent water abandonment problem, the number of new hydropower projects started nationwide has been significantly reduced, resulting in the continuous decrease of hydropower investment for four consecutive years from 2013 to 2016.In 2017, hydropower will invest 62.2 billion yuan, mainly in the construction of 24 new pumped storage units in 2016 and 26 new pumped storage units in 2017.The total investment in pumped storage units reached 14.2 billion yuan, up 68.6% year on year, making it the largest investment in pumped storage over the years.

Investment in thermal and coal power fell sharply, to the lowest level in nearly a decade

In 2017, the state made great efforts to prevent and defuse the risk of overcapacity in coal and electricity production.Investment in coal-fired power generation totaled 70.6 billion yuan in the whole year, down 27.4 percent year on year, and led to a 23.4 percent drop in investment in thermal power generation.In 2017, investment in both thermal and coal power was the lowest since 2006.Investment in gas power generation nationwide reached 14.4 billion yuan, unchanged from the previous year.

Investment in nuclear power is at its lowest level since 2009

With the gradual operation of nuclear power projects and the small scale of new projects started in recent years, the investment in nuclear power construction was 45.4 billion yuan in 2017, down 9.9% year on year and the lowest since 2009.

New energy generation to the east, central region transfer

Investment in new energy power generation totaled 96.6 billion yuan last year, down 17.3% from a year earlier.Among them, wind power investment reached 68.1 billion yuan, down 26.5% year on year, and the scale has been reduced for two consecutive years.Investment in solar power generation reached 28.5 billion yuan, up 18.2 percent year-on-year and up for the fourth consecutive year.Investment in wind power and solar power in the eastern and central regions accounted for 69.8 percent and 70.2 percent of total investment in wind power and solar power in China, 15.5 percent and 15.9 percent higher than the previous year, respectively.Investment in wind and solar power in the west, northeast and northeast regions accounted for 30.2 percent and 29.8 percent, respectively, down 15.5 and 15.9 percentage points from the previous year.

Increased concentration of power investment space

Ten provinces account for 66% of the total

1. Regional investment

Compared with the previous year, in 2017, except for the northeast and central China regions, the other four regions saw a decline in power investment.In terms of the characteristics of regional investment, the investment in north China is mainly in thermal power and wind power, accounting for 27.4% and 31.6% of the same type of investment respectively.Northeast region investment scale is smallest.Investment in nuclear power and wind power dominated east China, accounting for 45% and 26.4% of the same type of investment respectively.Investment in clean energy power generation dominated central China, accounting for 82.4% of the region's power investment.The northwest region mainly focuses on thermal power investment, accounting for 18.5% of the same type of investment in the country. The wind power in this region continues the downward trend of the previous year, with a sharp decline of 71.9% in 2017, leading to a sharp decline of 47.2% in the power supply investment in the northwest region.Nuclear power investment in the southern region accounted for 34.9 percent of the same type of investment nationwide.

2 minutes province investment looks

In 2017, 10 provinces including sichuan, jiangsu, guangdong, hebei, shandong, fujian, zhejiang, liaoning, yunnan and Inner Mongolia invested more than 10 billion yuan in power supply, of which the total investment in power supply accounted for 66% of the total investment in power supply nationwide.Among them, hydropower investment is the main investment in sichuan and yunnan, nuclear power investment is the main investment in jiangsu, guangdong and fujian, and thermal power investment is the main investment in hebei, shandong and Inner Mongolia.

Hydropower investment is concentrated in sichuan

Hydropower investment in sichuan reached 32.4 billion yuan, an increase of 20.9 percent over the previous year, accounting for 52.1 percent of the country's total hydropower investment. Hydropower investment in yunnan reached 8.9 billion yuan, and pumped storage power station projects in zhejiang, guangdong, hebei, anhui and shandong exceeded 1 billion yuan.

Investment in thermal power is relatively concentrated

Guangdong, hebei, ningxia, Inner Mongolia and jiangsu invested more than 5 billion yuan in thermal power, and the five provinces invested 38.1 billion yuan in thermal power, accounting for 44.4% of the total investment in thermal power nationwide.The state has implemented measures to reduce coal and power production capacity, and the investment in coal and power in 17 provinces has decreased year on year.Shandong and ningxia saw year-on-year decreases of 5.9 billion yuan and 5.3 billion yuan, respectively, down 59.3% and 41.5%, respectively.Hebei, Inner Mongolia, jiangsu and shandong invested more than 4 billion yuan in coal power.Guangdong, Beijing and jiangsu are the provinces that have completed the most investment in gas and electric power, accounting for 69.9% of the total investment in gas and electric power in China.Investment in gas and electric power in Beijing, tianjin, hebei, shanxi, henan and shadong totaled 4.7 billion yuan, up 26.4 percent from the previous year.

Investment in nuclear power in all provinces shrank year on year

Since no new projects have been started for two consecutive years and the scale of construction has been reduced, the investment in nuclear power in the seven provinces with nuclear power projects has been reduced to varying degrees.Guangdong, jiangsu and fujian together account for 66.2 percent of China's nuclear investment.

Wind power investment in eastern and central provinces accounts for a relatively large proportion

Hebei, jiangsu, shanxi, fujian, Inner Mongolia, shandong, henan and shaanxi have invested more than 3 billion yuan in wind power, with a total of 43 billion yuan invested in wind power in eight provinces, accounting for 63.2% of the total investment in wind power nationwide.Wind power investment in the eastern and central regions accounted for 47.5% and 22.3%, respectively.Year-on-year growth was 12.2 percent and 3.3 percent.

Investment in solar power generation is concentrated in 11 provinces

Eleven provinces, including shandong, zhejiang and shanxi, have invested more than 1 billion yuan in solar power generation, accounting for 77.4 percent of the country's total investment in solar power generation.Affected by the problem of light abandoning, xinjiang solar energy investment is only 0.021 billion yuan.
