State Grid 11th Five-Year Accumulated Investment of 1.2 Trillion Yuan

Since the "Eleventh Five-Year Plan" period, the State Grid Corporation of China has actively accelerated the development of the power grid and has fully supported the rapid economic and social development. During the “Eleventh Five-Year Plan” period, a total of 1.2 trillion yuan of grid investment was completed, which exceeds the sum of the investment in China’s 56-year grid since the establishment of the People’s Republic of China, and the total scale of the grid has doubled; the production of transmission lines with 110 kV and above capacity is 254,000 km, and the substation capacity is 1.27 billion. KVA, increasing by 60% and 118%, respectively; the UHV AC/DC demonstration projects representing the world’s highest grid technology levels have been completed and put into operation, marking China’s full mastery of the UHV transmission core technologies and full set of equipment manufacturing capabilities, which has driven the nation The electrical equipment manufacturing industry has been innovatively developed and has achieved "China Creation" and "China Leading" in the world's power grid science and technology field. In combination with the new trends in the world's energy revolution, it has proposed a strong smart grid development strategy, formulated development plans, systematically conducted pilot projects, and established China has an international leading position in the field of smart grids.

As of the end of 2010, the National Grid Corporation's 110 kilovolt and above lines had a length of 675,000 kilometers, which was 1.6 times that of 2005. The substation capacity reached 2.35 billion kVA, which was 2.2 times that of 2005. Compared with 2005, the State Grid Corporation’s electricity sales increased by 83.6% to 2.7 trillion kWh; the newly added transmission capacity was 140 million kW. The total length and transmission capacity of the DC transmission lines operated by the State Grid Corporation ranked first in the world. The trans-provincial power transmission capacity in the region has doubled, and the national power market transaction volume has increased by 3.6 times to 358.5 billion kwh. The large-scale, long-distance, and high-efficiency energy allocation capacity of the national grid has been significantly enhanced.
