Spanish wind project developer Corporación Eólica (CESA) has received permission from the Basque regional government and port authorities to install ten 2 MW Gamesa turbines on the Port of Bilbao's breakwater, jutting some 1800 metres into the Bay of Biscay on dockland at Punta Lucero. The semi-offshore project still needs a building license from Bilbao's city hall. CESA estimates it will cost EUR 10.4 million to build. Transmission cables can use an existing hollow along the length of the concrete breakwater. Holes will be bored into the concrete to lay the turbine foundations, set 200 metres apart. Regional government environmental conditions require a June construction start to prevent disturbance during the sea bird nesting season. The turbines will require anti-corrosion protection from the Bay of Biscay's often fierce waters. CESA says winds are more constant on the breakwater than on land, although estimated annual production, at 23.4 GWh, is similar to that of an inland plant of the same size. The project opens new territory for Gamesa Eólica, which has no experience in the offshore sector, nor any plans to enter it on a large scale.
