As a whole, the Siemens industrial group saw revenues increase 1% to €19.1bn in the first quarter of its financial year, while net income grew to €1.9bn, up from €1.5 billion a year earlier.
Due to its "strong start to the year", Siemens increased its forecast for 2017 profit margin from 10.5%-11.5% to 11%-12%. It also increased its earnings per share from €6.80-€7.20 to €7.20-€7.70.
In Q1 2017, the profit margin increased to 13% from 10.4% a year earlier. Earnings per share were also up 25% from €1.89 to €2.35, the company said.
For its wind business unit, profit increased by 119%, the company said with revenue increasing from €1.2bn to €1.4bn.
However, order totals fell 24% compared to the same period in 2016 to €1.4bn.
Siemens said this was due to an exceptionally high Q1 2016 which included a €1bn offshore wind order.
"Strong profitability [was] driven by the revenue increase, higher productivity, positive effects related to project execution, higher capacity utilisation, and a larger contribution from the service business," Siemens said.
Siemens' merger with rival wind turbine manufacturer Gamesa is expected to be finalised by April 2017.
