In China, wind power is beating nuclear

Wind Power Beats Nuclear Again in China. Earth Policy Institute
J. Matthew Roney. 5 Mar 15 China, the country that is building more nuclear reactors than any other, continued to get more electricity from the wind than from nuclear power plants in 2014. This came despite below-average wind speeds for the year. The electricity generated by China’s wind farms in 2014—16 percent more than the year before—could power more than 110 million Chinese homes.

China added a world record 23 gigawatts of new wind power capacity in 2014, for a cumulative installed capacity of nearly 115 gigawatts (1 gigawatt = 1,000 megawatts). Some 84 percent of this total—or 96 gigawatts—is connected to the grid, sending carbon-free electricity to consumers.

As China’s wind power installations took off in the mid-2000s, electric grid and transmission infrastructure expansion could not keep pace. But the situation is improving: China is building the world’s largest ultra-high-voltage transmission system, which is connecting remote, wind-rich northern and western provinces to the more populous central and eastern ones. At the same time, the government is providing incentives for wind farm development in less-windy areas nearer to population centers. Advances in wind power technology can allow greater capture of energy in spots without the strongest wind resources.wind resources.

China’s wind power goal is to have 200 gigawatts connected to the grid by 2020. According to China’s National Energy Administration, the country has some 77 gigawatts of wind capacity now under construction, bringing this goal that much closer to being realized. Efforts to bolster the grid and connect more turbines are reducing the amount of potential wind generation lost each year due to curtailment, when turbines must stop producing because the grid cannot take on any more electricity. Since 2012, the rate of this curtailment at China’s wind farms has dropped by more than half; however, further improvements are still needed……..ttp://www.earth-policy.org/data_highlights/2015/highlights50
