Iberdrola also confirmed last year's announcement that it is aiming to bring more than 1.4GW of offshore and onshore wind power online by 2014 as part of an a EUR 8.82 billion investment, split between transmission and wind.
The company said it plans to develop transmission lines in the US and the UK, the latter a subsea cable between England and Scotland.
As things stand, Iberdrola is still the world's number one wind developer. However, there are signs its position could be under threat.
Last month, Longyuan Power general manager Xie Changjun predicted that his company will overtake Iberdrola by 2014.
Speaking at the 20th anniversary of Longyuan's launch, Xie said: "If all goes well, we will surpass Iberdrola Renewables to be the largest wind farm developer in the world next year."
