Wind Leaves Nuclear Behind in China

In China, wind power is leaving nuclear behind. Electricity output from Chinas wind farms exceeded that from its nuclear plants for the first time in 2012, by a narrow margin. Then in 2013, wind pulled awayoutdoing nuclear by 22 percent. The 135 terawatt-hours of Chinese wind-generated electricity in 2013 would be nearly enough to power New York State.
Once Chinas Renewable Energy Law established the development framework for renewables in 2005, the stage was set for winds exponential growth. Wind generating capacity more than doubled each year from 2006 to 2009 and has since increased by nearly 40 percent annually, to reach 91 gigawatts by the end of 2013 (1 gigawatt = 1,000 megawatts). Over 80 percent of this world-leading wind capacity is now feeding electricity to the grid.
Wind generation in 2013 could have been even higher, by an estimated 10 percent, but for the problem known as curtailmentwhen wind turbines are stopped because the grid cannot handle any more electricity. To help reduce curtailment and reach the official 2020 goal of 200 grid-connected gigawatts, China is building the worlds largest ultra-high-voltage transmission system. The raft of projects now under construction will connect the windier north and west to population centers in the central and eastern provinces.
Why is Wind Power Generation Surpassing Nuclear?
One of the reasons why nuclear power has not kept up with wind in China is the relative time it takes to get a project up and running. Whereas the typical Chinese nuclear reactor takes roughly six years to build, a wind farm can be completed in a matter of months.
