Investment and Operation of Hydropower

SPIC has the qualifications for development and EPC contracting of hydropower projects. On the basis of addressing resettlement and ecological protection properly, and following China’s hydropower development principle of “river basin,cascade, rolling and integrated development”, SPIC carries forward the development and construction of cascade hydropower plants (HPPs) on the upper reaches of the Yellow River and the Yuanshui River drainage basin in Hunan in an orderly fashion and has successfully built two cascade hydropower clean energy bases in the above two regions.

SPIC has 142 HPPs in operation with a total installed capacity of 20,943 MW, distributed in 12 provinces including Qinghai, Hunan, Yunnan, Guizhou, Guangxi, Sichuan, etc. 1,000 MW and larger HPPs that have been put into commercial operation include Longyangxia HPP, Laxiwa HPP, Lijiaxia HPP, Gongboxia HPP, Jishixia HPP, Wuqiangxi HPP and Sanbanxi HPP. Twelve hydropower stations are under construction with a total installed capacity of 910.5 MW.

Apart from developing hydropower in China, SPIC plans to develop seven cascade HPPs and a construction power station (Chipwi Nge HPP) on the upper reaches of the Ayeyawady River, Myanmar, with a total installed capacity of 21.6 GW and an average annual power generation of 114 TWh.

Representative projects
 
Laxiwa HPP

The second large-scale cascade HPP on the section from Longyangxia to Qingtongxia of the upper reaches of the Yellow River. The single unit capacity is 700 MW and the total installed capacity is 3,500 MW. In 2010, all five units were put into operation with average annual power generation of 10.2 TWh. The HPP has a concrete double-curved arch dam with the maximum dam height of 250 m and the total reservoir capacity of 1.1 billion m 3 . It has the highest dam,largest capacity and power generation in the north of China.

 
 
Longyangxia HPP

It is the large-scale hydropower project designed and built by China independently,representing the highest level of China’s hydropower engineering in the 1980s. The single unit capacity is 320 MW and the total installed capacity is 1,280 MW; the average annual power generation is 6 TWh.

 
Changzhou HPP

Located in the Pearl River Basin, due to its large scale and capacity, and large number of units, it is named as “world-class HPP with tubular turbines” by industry experts. It crosses two islands and three rivers, and is installed with 15 bulb type tubular turbines with a single unit capacity of 42 MW. Thirteen protection and drainage pumping stations were built in the reservoir area and two supporting substations were built.

 
 
Wuqiangxi HPP

It is the largest HPP in Hunan Province, with a single unit capacity of 240 MW and a total installed capacity of 1,200 MW. Its main function is to generate electricity, supplemented by flood control, navigation and other purposes.

Full Industry Chain of Solar Power

SPIC has the greatest total installed capacity of solar power in the world and owns a complete industry chain in PV power including R&D, planning and design, manufacturing of polysilicon, cells and modules, project construction,training, etc.

By the end of 2015, SPIC owned a solar power capacity of 4,849.9 MW, and has established large-scale new energy bases in Jiuquan, Gonghe, Golmud, Hami, Yancheng, etc. SPIC’s solar power assets are located in 15 provinces and autonomous regions in China including Qinghai, Xinjiang, Hebei, Jiangsu, Gansu, etc. (overseas assets excluded).

Through the coordinated operation of hybrid hydro-solar and hybrid wind-solar projects and research on key technologies, SPIC successfully solved the problems related to the volatility, randomness and intermittency of daily PV power output and improved the quality of PV power output and the stability of grid operation, which filled the gap of key technologies for large-scale hybrid hydro-solar projects in the world.

Representative projects
 
Golmud PV Power Plant

Located in the Golmud Gobi Desert, Golmud PV power plant is the largest one-off PV investment in the world, with an installed capacity of 500 MW.

 
 
Jiangsu Jianhu Solar Power Plant

The Jiangsu Jianhu Hybrid Fishery-Solar Project has an installed capacity of 66 MW. The large-scale PV power plant was built on the local lake, intertidal zones and fish ponds. Multipurpose use of land increases both the agriculture and fishery revenue, and improves the integrated utilization efficiency of land.

 
 
Longyangxia Hybrid Hydro-Solar Project

With a total installed capacity of 850 MWp, the project makes best of the complementarities between hydropower and solar power and the quick adjustment ability of Longyangxia HPP to make up for the active output from the PV power plant, so as to improve power quality.

 
Manufacturing of PV cells and modules

SPIC is capable of manufacturing crystalline silicon, wafers, cells and modules with the facilities to produce 2,500 tons of polysilicon, 200 MW of cells and 200 MW of modules each year in Xining, Qinghai Province and 200 MW of cells and 100 MW of modules each year in Xi’an, Shaanxi Province.

Design of PV power plants
SPIC designed the 18 MW Jining PV Power Plant, Asia’s largest non-silicon thin-film PV power plant.
 
Investment and Operation of Wind Power

By the end of 2015, SPIC had a wind power capacity of 9,978.3 MW distributed in 25 provinces and autonomous regions including Qinghai, Xinjiang, Gansu, Inner Mongolia, Jiangsu, etc.

SPIC follows the principle of attaching equal importance to centralized and distributed development and utilization of wind power. Given the conditions of wind power consumption and technological development, SPIC expedites the distributed development of projects in China’s central and southeastern regions,promotes large-scale onshore wind power bases and intertidal and offshore wind power in coastal regions step by step.

Meanwhile, as one of the earliest wind power designers in China, SPIC has completed the feasibility studies and construction drawings of more than 90 wind farms.

Representative projects
 
Jiuquan Gobi Wind Farm in Gansu Province

With a total installed capacity of 1,070 MW, the wind farm is located in the Gobi Desert of Gansu. 200 MW Dafeng Intertidal Wind Farm in Jiangsu Province

 
200 MW Dafeng Intertidal Wind Farm in Jiangsu Province

With a total installed capacity of 200 MW, the project is located in the costal intertidal zone of Dafeng, Jiangsu. SPIC designed and built the 21 km coastal cofferdam to overcome the difficulty of construction in the intertidal zone.
