Speaking at the inauguration of Gamesa's first turbine for offshore use, Martin said: "Let's not kill this sector. We have to look at offshore too. We must, but our country doesn't seem to be interested.
The Spanish minister for industry, energy and tourism Jose Manuel Soria, who attended the inauguration, replied that the need to reduce the country's deficit and the high cost of renewable energy meant a change in policy was not possible.
The first G128-5MW turbine was installed in Arinaga Quay on Grand Canaria and marks Gamesa's first move into the offshore wind sector.
Since it started operating in July, the turbine has sent more than 1GWh to the grid, said Gamesa. The facility's start-up is a prerequisite for the securing of certification, slated for the first quarter of 2014.
The company also revealed that it is planning to develop a 7-8MW offshore turbine, with a prototype expected in 2017. The machine would rival Samsung's 7MW and Vestas' 8MW turbines, both of which are in development.
