Chinese city launches wind power lottery to ease grid strains

SHANGHAI: The city of Yanan, a major wind power base in northwest China’s Shaanxi province, has introduced a lottery system to decide which wind projects will go ahead this year, a sign that grid constraints are forcing local governments to restrict capacity. China has been aggressively developing alternative power as part of its efforts to cut pollution and greenhouse gas emissions. Grid-connected wind power reached 163.7 gigawatts (GW) last year, up 10.1 percent on the year and amounting to 9.2 percent of total generating capacity. But capacity expansion has outpaced grid construction, and large numbers of wind, solar and hydropower plants are unable to deliver all their power to consumers as a result of transmission deficiencies, a problem known as curtailment. According to a Yanan planning agency, the city was given permission to build 900 megawatts of wind capacity this year, but 1,300 megawatts (or 1.3 GW) have already been declared eligible for construction, forcing authorities to whittle down the total number of projects.
