Wind turbine sizes keep growing as industry consolidation continues


The Global Wind Energy Council has published its annual Supply Side Analysis 2019 report. According to the report, 22.893 wind turbines were installed worldwide in 2019 supplied from 33 manufacturers and representing more than 63GW of capacity.

Vestas remains a major manufacturer in 2019, accounting for 18 percent of all wind turbines installed in 2019, thanks to its global diversification strategy with installations in over 40 countries.

Siemens Gamesa Renewable Energy moved up one position to second place, with the supplier doubling its offshore wind installation in 2019 and expanding its geographic coverage.

Goldwind fell one position to third place despite the company increasing its annual installations by 19 percent in 2019 thanks to an installation rush in its home market, China.

Of the top fifteen wind turbine suppliers in 2019, 10 built last year offshore wind turbines representing 99.9 percent of the total 6.1GW of offshore wind capacity installed in 2019.

Last year was the first time we saw a solely offshore wind manufacturer, MHI Vestas, enter the world top fifteen, showing the increasingly important role the offshore industry plays in driving the growth of wind power.

“We are continuing to see market consolidation for turbine suppliers globally, with the number of suppliers declining from 37 in 2018 to 33 in 2019. At the same time, the top six turbine vendors collectively increased their market share from 70 per cent in 2018 to 72 per cent in 2019. Within this competitive landscape, current trends favor companies that shift from being solely manufacturers to evolving into holistic systems and solution providers to allow for greater market diversification.

“The wind sector is a leader in innovation and technology, and it can clearly be seen in the impressive increases in turbine sizes. In 2019, the average turbine size surpassed 2,750 kW and in some markets like Denmark and the UK, turbines passed the 5,000 kW milestone thanks to offshore wind development. This is a 72 per cent increase for average turbine size in the past decade alone, and is a testament to the industry‚Äôs leadership in technology innovation and maturity of the global sector.”

Ben Backwell, CEO of GWEC.

“More than 63 GW wind power capacity was delivered and installed based on supply side data in 2019, a new record for the industry. 2020 was forecasted to be another record breaking year, however, disruption of the global supply chain and delays on wind project execution has forced major stakeholders in the wind industry to withdraw their 2020 financial and production guidance as well as adjust their market outlook for the year.

“In 2019, eight Chinese turbine vendors were included in the top fifteen supplier ranking, but the top two spots were held by European suppliers Vestas and Siemens Gamesa Renewable Energy. With the COVID-19 crisis now disrupting supply chains, manufacturing and project execution globally, it is likely that these rankings will shift in 2020 depending on how quickly countries and businesses can recover from the pandemic.”

Feng Zhao, Strategy Director of GWEC.

GE Renewable Energy and Envision stay in fourth and fifth spot respectively for global market share, both seeing rises due to installation rushes in their US and Chinese home markets.

These installation rushes also helped Mingyang and Nordex Acciona, both moving up one spot to sixth and seventh, respectively.

Enercon dropped by two positions to eight place in 2019, primarily due to a significant decline in installations in its home market, Germany. 

For the first time ever Windey entered the top ten as the supplier doubled its installations in China, moving up four positions to ninth.

Rounding out the top fifteen wind turbine suppliers in 2019 are Chinese suppliers Dongfang, Sewind, CSIC Haizhuang and United Power along with German supplier Senvion and the Danish-Japanese joint venture MHI Vestas.
