Vestas, Gamesa and Nordex all saw their stock prices shoot up, with an average increase of 215% over the first eight months of the year following positive results.
All three appear to be reaping the rewards of drastic cost-cutting measures.
However, it was not all good news for turbine manufacturers on the stock market, with Suzlon seeing a painful 69% collapse in its share price, leaving 80% of surveyed analysts to recommend selling the stock.
The second quarter saw Siemens storming ahead of the competition in terms of orders, with 1.5GW of sales. Vestas was not too far behind, selling 848MW, but normally bullish GE lagged, with orders for just 315MW over the three months.
Globally, there was a rush to secure sites for development, with a 117% increase in the second quarter compared with a year ago. But turbine purchases were down 36% and project financing came in 13% lower.
Unsurprisingly it was all go in Latin America. Installed capacity shot up 19% since the start of the year, with the region adding 896MW. Brazil accounted for more than half of the increase.
It was a leaner period for the US, which added only 563MW. But there were signs that the looming production tax credit deadline is spurring developers on, with a slight increase in project starts compared with the same period last year.
China and India both added substantially to their capacity. The year to October saw China switch on 6.7GW, while in India there was a 1.3GW increase.
Germany led in terms of turbine deals, putting pen to paper for more than 1GW of capacity. Brazil was the best of the rest, with 513MW ordered.
Analysts views on the sector remained largely unchanged with 48% holding negative stances, while 21% were positive.
