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.
