Despite a slowing down of global wind energy power installations in 2013, a new report has found that global cumulative wind power capacity will more than double from 319.6 gigawatts (GW) at the end of 2013 to 678.5 GW bu 2020. The report, “Wind Power, Update 2014 – Global Market Size, Average Price, Competitive Landscape, and Key Country Analysis to 2020,” was released by GlobalData.

The report finds that China, the largest single wind power market responsible for 45 percent of total global annual capacity additions in 2013, is expected to have a cumulative wind capacity of 239.7 GW by 2020. China overtook the U.S. as the leading market for installations in 2010, when it added a massive 18.9 GW of wind capacity.

Harshavardhan Reddy Nagatham, GlobalData’s Analyst covering Alternative Energy, said: “China doubled its cumulative wind capacity every year from 2006 to 2009 and has continued to grow significantly since then. Supportive government policies, such as an attractive concessional program and the availability of low-cost financing from banks, have been fundamental to China’s success. While China will continue to be the largest global wind power market through to 2020, growth for the forecast period will be slow due to a large installation base.”

The report also finds that the U.S. will remain the second largest global wind power market in terms of cumulative installed capacity, increasing from 68.9 GW in 2014 to 104.1 GW in 2020. This will largely be driven by renewable energy targets in several states, such as Alaska’s aim to reach 50% renewable power generation and Texas’ mandate to achieve 10 GW of renewable capacity, both by 2025. An additional driver would include the reinstatement of the Production Tax Credit that expired on December 31, 2013.

Nagatham concluded, “The slump in 2013 was largely a product of a decrease in installations in the US and Spain. While there are likely to be further slight falls in annual capacity additions in 2015 and 2016, overall industry growth will not be affected as global annual capacity additions are expected to exceed 60 GW by 2020.”
