Madrid-based start-up BlueFloat Energy and engineering group Sener are planning an up to 1GW floating wind farm off the Costa Brava in the Spanish region of Catalonia, but the project is still in an early phase of development trying to ease concerns of local municipalities.

The Tramuntana wind farm would be located in a strong-wind zone at a distance of some 24km off the coast of the region of Empordá, northeast of Barcelona.
