Update: Following a formula error, FTI Consulting revised the average turbine size installed in 2017 down to 2,404kW from the orignially stated 2,525kW. We apoloise for the error in reporting the earlier figure. 

The 2.404MW average turbine size worldwide is 0.244MW higher than in 2016, according to figures from FTI Consulting.

In its Global Wind Market Update — Demand & Supply 2017 report, FTI found the UK (3.764MW), Denmark (3.408MW) and Germany (3.263MW) — driven by their offshore markets — helped to grow the average turbine size.

The UK was the first country to have an average installed turbine size above 3.5MW. Across Europe as a whole, the average size was above 3MW — the only region to reach this benchmark.

In the world's biggest markets, the average capacity was below the 2.5MW mark: 2.332MW in the US, 2.111MW in China and 1.933MW in India. However, it is the first time the average turbine capacity in China exceeded 2MW, FTI said.

In Canada, which has no offshore capacity, the average turbine capacity was 3.091MW, FTI noted.

According to FTI, 21,691 individual turbines were installed globally last year, supplied from 46 turbine manufacturers.


FTI reaffirmed the top five manufacturers in 2017 by turbine supply it announced in February.

Vestas retained its top spot, increasing its 16.5% market share by 0.9% year-on-year, with the help of its MHI Vestas offshore wind joint venture.

Siemens Gamesa Renewable Energy moved up to second, as a result of the merger, which was finalised in early April 2017. The new combined Spanish-German firm also now has the largest market spread, supplying turbines to 35 markets in 2017, compared to the previous leader Vestas (30 markets in 2017).

Chinese manufacturer Goldwind saw its market share fall 1.1% compared to 2016, due to the slowdown in its home market.

Similarly, GE Renewable Energy's market share fell 4.5% year-on-year, after it lost out in the US to Vestas once again.
