Electricity Regulatory Commission Releases "Report on Monitoring of Wind Power Dissipation in Key Regions"

In 2011, the average utilization hours of wind farms in the “Three North” region was 1,907 hours, a year-on-year decrease of 266 hours; the amount of wind rejected was 12.3 billion kwh, the rate of wind rejection was approximately 16%, and the electricity cost of wind rejects was approximately 6.6 billion yuan.

Recently, the China Electricity Regulatory Commission issued the “Regulations for Supervision of Wind Power Dissipation in Key Regions” (hereinafter referred to as the “Report”), which detailed the construction of wind power in the northeast, north, and northwest regions (hereinafter referred to as the “Three North” regions), and detailed information on the merger and acquisition of wind power. Disclosure. The “Three North” region is the main area for wind power development in China. "The report shows,

As of the end of 2011, the nationwide grid-connected wind power was 45.05 million kilowatts, of which 38.22 million kilowatts were grid-connected wind power in the “Three North” region, accounting for 87.7% of the total. In 2011, the national wind power generation amounted to 73.174 billion kwh, of which wind power generation in the “Three North” region was 63.537 billion kwh, accounting for 86.8%. In 2011, the average utilization hours of wind farms in the “Three North” region was 1,907 hours, a year-on-year decrease of 266 hours; the amount of wind rejected was 12.3 billion kwh, the rate of wind rejection was approximately 16%, and the electricity cost of wind rejects was approximately 6.6 billion yuan.

The SERC pointed out in the “Report” that the lack of coordination between wind power planning and power grid planning has exacerbated the restriction of wind power consumption in some areas; the speed of wind power construction has not synchronized with the speed of power grid construction and has exacerbated the operation of some regions; wind power has consumed market space locally. Limited, in some areas, the capacity of the transmission channel is insufficient, and it can neither be consumed on the spot, nor can it be sent in a timely manner; the problem of peak regulation of the system is more prominent; the coordinated operation mechanism of the market and all kinds of power supply to promote wind power consumption is still not perfect.

In response to the issue of wind power consumption, the Electricity Regulatory Commission proposed in the “Report” that the unified planning of wind power and power grids should be further strengthened; the approval and construction of wind power projects and transmission projects must be accelerated; the wind power generation dispatching should be further strengthened and optimized; and flexible Market mechanism, to coordinate the contradiction between wind power and traditional energy; take multiple measures, develop the load, improve the system load characteristics; further improve the price and fiscal policy, and improve the wind power generation incentive mechanism.
