 The Islay LIMPET (Land Installed Marine Powered Energy Transformer) wave power generator was designed and built by Wavegen and researchers from the Queen's University of Belfast, and was financially backed by the European Union.Known as Limpet 500, due to cabling constraints its capacity is limited to providing up to 150 kW of electricity into the island's grid.In 2000 it became the world's first commercial wave power station.
