????Xinhua Energy, October 29??SGCC spokesperson and the Deputy Director General of Department of Strategic Development and Planning Zhang Zhengling said at the press conference of accelerating the accommodation of wind power held on October 28 in Beijing that as of the end of September 2013, SGCC has integrated 64.26GW of installed capacity of wind power, up by 21.5% year on year. The situation is developing for the better.

????Data show that the newly added integrated installed capacity of wind power reached 7.9GW within SGCC??s service area from this January to September. The generation of wind power amounted to 93.1TWh, up by 37%. The accumulative utilization hour of wind power was 1514, increased by 130. Wind power operation indicators hit historical high. Jiang Liping, vice president of SGERI, expected there would be less abandoned wind energy this winter compared with last year.

????China has the biggest wind power capacity in the world. It is introduced that the average annual growth of integrated installed capacity of wind power within SGCC??s service area from 2006 to 2012 was 76%, with the generation capacity up by 85% each year. The power generation from eastern Inner Mongolia, western Inner Mongolia, Gansu and northern Hebei accounted for 28%, 12%, 9%, and 8% of the power consumption respectively, almost the same as Spain and Germany, reaching world level. SGCC has become the grid with the biggest capacity and the fastest growth of wind power in the world.

????According to the national plan for the wind power, in 2015, China will have 100GW of wind power and the number will reach 200GW by 2020. 80% will concentrate in the Three North region. Locally, the wind power in the Three North region has reached 20%, a relatively high level. However, nationwide, the installed capacity of wind power only accounted for 6%. There are abundant peak-shaving resources in middle and eastern China and the potential to accommodate wind power is yet to be exploited.

????Zhang Zhengling pointed out that the bottleneck for wind power accommodation is the weak connection between big regions and the lack of a national market and a matching national interconnection capability. Right now, a transmission proposal for big wind power bases has been submitted to the NEA, awaiting approval.

????It??s learned that Hami-Zhengzhou ??800kV DC project to be commissioned by the end of this year will transmit 8GW of wind power. SGCC has accelerated the preparation for the Phase 2 project of Gansu Jiuyuan wind power transmission. In June, its auxiliary 330kV output project for the Phase 2 project was approved. In September, Jiuquan-Hunan ??800kV UHV DC transmission project got its route permission, which can deliver 8GW of wind power upon completion. The 500kV transmission and transformation project in Kangbao, Shangyi and Zhangbei can transmit 3.9GW of wind power out from Zhangjiakou after being commissioned in 2014. The third line between Gaoling and Tianma has started construction to accommodate wind power from Northeast China in North China.

????In addition, SGCC strengthened the dispatching of wind power, promoting wind power heating and electricity substitution. Multiple measures have been taken to promote the integration of new energy. Zhang Zhengling said that SGCC would stick to the development concept of constructing big bases to integrate into the big grid, strengthen unified planning, improve auxiliary policies, speed up the construction of UHV trans-regional transmission channels and peak-shaving power resources, expand the accommodation market for wind power, and make sure to meet the development goal of wind power in China.
