FTI also raised its cumulative global capacity prediction by 2.7% from its Q1 report, to 960GW.
However, FTI said the growth could slow in 2016 and 2017 as the Chinese and US markets contract.
Between 2014-2019, FTI predicts a compound annual growth rate (CAGR) of just 0.6%. But between 2019 and 2024, the market is expected to reignite with an average annual growth of 6.2%.
Over the next ten years, the Asia-Pacific region is expected to add around half of all new capacity, FTI said.
In the first half of 2015, Vestas was the leading OEM by disclosed firm order intakes, followed by Chinese manufacturers Goldwind and United Power buoyed by their domestic market.
For offshore, however, there is a surprise leader with Senvion winning the largest amount of confirmed orders with 443MW. MHI-Vestas (423MW) and Siemens (337MW) follow closely. Both have also received further orders in Q3, whereas Senvion has not.
