In the "Twelfth Five-Year Plan" State Grid pumped storage power station technology research has yielded fruitful results

2015 is undoubtedly the most fruitful year
for the construction of pumped storage power stations of the State Grid Corporation of China.
During the "Twelfth Five-Year Plan" period, with the successful entry of pumped storage construction in China from the exploration and development period to the industrial growth period, the company's pumped storage power station development achievements have attracted attention and stood at a new historical high
.

During the "Twelfth Five-Year Plan" period, with the rapid development of clean energy and the accelerated construction of strong smart grids, pumped storage power stations, as the most mature, economical and irreplaceable large-scale power storage devices at present, have ushered in an important period of strategic development opportunities
.
At the beginning of the "Twelfth Five-Year Plan", the total installed capacity of the national power was 962 million kilowatts, of which the assembly capacity of pumped storage machines was 16.
94 million kilowatts, accounting for less than 1.
8% of the total installed capacity of the national electricity, at the same time, the scale of pumped storage units under construction in the country was 11.
28 million kilowatts, and the pumped storage industry was still in the stage of exploration and initial development
.

After the rapid development during the "Twelfth Five-Year Plan" period, by the end of 2015, the installed capacity of pumped storage power stations nationwide was 22.
74 million kilowatts, 1.
34 times that of the early "Twelfth Five-Year Plan", and the scale of pumped storage projects under construction was 23.
08 million kilowatts, and the capacity of pumped storage units had exceeded that of the United States
。 In the past five years, the company has firmly adhered to its strategic goals, approved the start of 10 pumped storage projects with an installed capacity of 14.
6 million kilowatts, and the installed capacity of pumped storage power stations in operation in the company's business area is 16.
46 million kilowatts, the scale under construction is 17.
3 million kilowatts, and the operating capacity has quadrupled compared with the end of the "Eleventh Five-Year Plan", achieving a new leap
in installed scale and development quality.
