Siemens Gamesa Renewable Energy led the global 51.7-GW wind turbine market in 2017 with 18% of the market, according to Bloomberg New Energy Finance's latest industry report.
Siemens Gamesa installed 9.5 GW of wind turbines in 2017, 28.3% of which were offshore turbines. The company's market share grew 28% year over year after Siemens AG merged its wind business with Gamesa Corporación Tecnológica SA, turning the newly formed company into one of the world's largest turbine suppliers.
"Onshore is clearly positioned to gain market share," CEO Markus Tacke said during the company's Feb. 15 analyst day. "We have the critical mass out of this merger now established to be in as many countries as needed to make this a successful business."
The Spanish company snatched the top honors from Vestas Wind Systems A/S from 2017's rankings. However, the Danish turbine maker was the biggest turbine installer in onshore wind with 7.7 GW in 2017 compared to Siemens Gamesa's 6.8 GW.
Combined, Siemens Gamesa, Vestas, Xinjiang Goldwind Science & Technology and General Electric Co. accounted for 53% of the world's wind turbine market in 2017.
Tom Harries, Bloomberg New Energy Finance's senior wind analyst, said in a Feb. 26 news release that there was more distance between the top four suppliers and everyone else in 2017 compared to 2016. GE had over 1.7 GW in turbine installations more than fifth-place German manufacturer ENERCON GmbH did in 2017.
Bloomberg New Energy Finance also said there were stark differences between the turbine makers' regional footprints. Companies tend to have a stronghold in their home region. For example, more than 90% of Goldwind's commissioned turbines were in China in 2017 while almost all of Enercon's were in Europe.
In the U.S., a different market leader story played out in 2017. Vestas led the American market for the second year in a row, capturing 35% of the 7 GW of new wind capacity commissioned in 2017. GE held 29% of the market it used to dominate, according to the American Wind Energy Association, while Siemens Gamesa was responsible for 23% of new turbines installed. GE was the top U.S. turbine maker for 13 years before relinquishing that spot to Vestas in 2016, controlling more than 40% of the U.S. wind turbine market as recently as 2015.
Onshore turbine installations fell 12% to 46.9 GW in 2017, partially due to a slowdown in the Chinese market. According to the Global Wind Energy Council, China added 19.5 GW of new wind capacity in 2017, compared to 23 GW in installations in 2016. Bloomberg New Energy Finance estimated that onshore wind will rebound to 55 GW in 2018 if China returns to normal growth and if Latin America can continue its wind expansion.
