Hydropower General

Hydropower is clean energy, renewable, non-polluting, and low in operating costs. It is convenient for peak power regulation and is conducive to improving resource utilization and comprehensive economic and social benefits. In the context of increasing global traditional energy resources, countries around the world have generally prioritized the development of hydropower and vigorously used hydropower resources. China ranks first in the world both in the amount of proven hydropower resources and the potential for development of hydropower resources.

Hydropower Status

As a renewable and clean energy source, hydropower occupies an extremely important position in the history of China's energy development, and supports sustainable economic and social development. In the 21st century, especially the advancement of the reform of the power system has mobilized the whole society to participate in the development of hydropower, and China's hydropower has entered a period of accelerated development. In 2004, marked by the commissioning of Gongboxia Unit 1, China's hydropower installed capacity exceeded 100 million kilowatts, surpassing the United States and becoming the world's largest hydropower country. A large number of huge hydropower stations including Xiluodu, Xiangjiaba, Xiaowan, and Laxiwa have begun construction. In 2010, marked by the commissioning of Xiaowan Unit 4, China's hydropower installed capacity exceeded 200 million kilowatts. At present, China is not only the world's largest hydropower installed country, but also the largest and fastest-growing country in the world. It has gradually become the center of world hydropower innovation.

Hydropower resources are China's advantageous resources. The development of hydropower is a requirement for the development and structural adjustment of the energy industry, a requirement for the use of land and resources and a regional economic revitalization, and a requirement for national environmental protection and sustainable development. After decades of construction and practice, China's hydropower technology has ranked at the forefront of the world, which is sufficient to support the vigorous development of the hydropower industry. The reform of the national power system and the diversification of hydropower investment entities will inject new vitality into the development of the hydropower industry. With the further development of the economy and society, the increasing requirements for environmental protection, the optimization and adjustment of the power structure, and the full implementation of the western development strategy, China's hydropower industry has ushered in increasing opportunities for development.

From 2007 to 2010, the average annual growth rate of China's hydropower industry was close to 20%, and the industry showed rapid growth. In 2011, China's hydropower industry realized a total industrial output value of 188.564 billion yuan, an increase of 6.66% over the same period of the previous year, and the industrial output value was 0.40%. The decline in the total industrial output value, growth rate, and proportion of the hydropower industry is mainly due to the new regulations on industrial division standards above designated size in 2011. The main business income of enterprises must reach 20 million yuan and above, compared with the previous 5 million yuan. Yuan and above have been greatly improved, making some small hydropower companies' data impossible to count, and the data performance has declined. Overall, the actual scale of the hydropower industry has maintained rapid growth.

In terms of economic indicators of the hydropower industry, from January to December 2011, the total sales revenue of the hydropower industry reached 18.889 trillion yuan (the sum of the sales revenue of industrial enterprises above designated size), a year-on-year increase of 10.66%; the total profit reached 28.327 billion yuan, and the accumulated assets The total amount reached 1.264207 trillion yuan. In 2011, China added 15 million kilowatts of hydropower capacity, and a number of new hydropower projects such as Ahai, Jinpingping, Nuozhadu, Monkey Rock, and Shenzhen Pumped Storage were approved for construction.

In 2012, the global hydropower generation increased by 4.3, which was higher than the historical average. All the net increase in power generation came from China, accounting for 100% of the global net hydropower annual growth, setting a record for the largest annual increase in a single country in the data sheet. According to domestic statistics: In 2012, the country s new hydropower installed capacity was 15.51 million kilowatts. By the end of 2012, the nation s installed hydropower capacity reached 248.9 million kilowatts (including 20.31 million kilowatts of pumped storage), accounting for 21.7 of the country s installed electricity capacity. An increase of 3.2 percentage points over the previous year. In 2012, the average utilization hours of hydropower generating equipment of 6000 kW and above for the whole year was 3555 hours, a year-on-year increase of 536 hours.

In 2012, China s hydropower consumption reached 194.8 million tons of oil equivalent, an increase of 22.8 from 158.2 million tons of oil equivalent in the previous year (2011); in 2012, China s hydropower consumption was 194.8 million tons of oil equivalent Equivalent, accounting for 23.4 of the global hydropower consumption of 831.1 million tons of oil equivalent, becoming the world's largest hydropower producer / consumer, and the second largest Brazilian producer / consumer of hydropower production / consumption (94.5 million tonnes of oil equivalent) Of 206.

Hydropower related data

From January to September 2015, the country s new power generation capacity (officially put into production) was 74.29 million kilowatts, of which hydropower 10.85 million kilowatts and thermal power 39.55 million kilowatts. In addition, from January to September 2015, the cumulative average utilization hours of power generation equipment nationwide was 2,972 hours, a year-on-year decrease of 232 hours. Among them, the average utilization hours of hydropower equipment was 2639 hours, a reduction of 84 hours; the average utilization hours of thermal power equipment was 3247 hours, a reduction of 265 hours. ^[1-2]

Hydropower Significance

Water conservancy and hydropower are the basic industries for national economic and social development. Water conservancy and hydropower projects have a long construction period, large investment, and many cooperative departments. They are greatly affected by natural resources, terrain, geology, and hydrometeorological conditions. The preparation of proposals for water conservancy and hydropower projects should follow the national policies and policies on infrastructure and water conservancy Regulations of the industry and related industries, and shall comply with relevant technical standards.

Water conservancy and hydropower projects are also affected by the local economic development level, transportation and other resource market conditions. Therefore, proposals for water conservancy and hydropower projects should be based on the general requirements of national economic and social development planning and regional economic development planning. Based on the comprehensive utilization plan or professional plan of the river basin (region), the development goals and tasks are proposed, and the construction conditions of the project are investigated and the necessary survey work is conducted. After analyzing the financing, the construction projects and project construction are selected and selected. The scale, location, and construction time demonstrate the necessity of the project construction and preliminary analysis of the feasibility and rationality of the project construction.

The proposal for water resources and hydropower projects is an important stage in the national capital construction process. After the project proposal is approved, it will be used as the basis for inclusion in the national medium- and long-term economic development plan and the feasibility study.
