Caterpillar (NYSE: CAT) will supply generator power to Principle Power, a renewable energy technology developer, for its WindFloat Prototype project in Portugal. The grid-connected floating structure supports a Vestas V80-2.0 MW turbine with an Olympian GEP 88-4 generator set for standby power, rated at 88 kVA. The deal was handled by Cat dealer Barloworld STET, located in Prior Velho, Portugal.
The project is being carried out by WindPlus, a joint-venture company led by Portuguese energy group EDP. The project is being tested 3 miles offshore near the northern town of Povoa do Varzim, Portugal. Like deepwater drilling applications, wind and the waves will both be affecting the platform at any time, making stability key. The Olympian generator set was used during offshore transport and for standby power following installation.
The features of the WindFloat dampen wave and turbine induced motion, enabling wind turbines to be sited in previously inaccessible locations, where water depth exceeds 50 meters (165 feet), and wind resources are superior. Principle Power said that similar projects are in development for the installation of commercial WindFloat units at U.S. and European offshore wind farms.
