The European Marine Energy Centre (EMEC) is a Scottish Government-backed research facility based in Stromness, Orkney that has installed a wave power testing system at Billia Croo on the Orkney mainland and a tidal power testing station on the nearby island of Eday.1 At the official opening of the Eday project the site was described as "the first of its kind in the world set up to provide developers of wave and tidal energy devices with a purpose-built performance testing facility."2

Wave Power
The wave site at Billa Croo consists of four berths located about 2km from shore and in a water depth of around 50m.
Pelamis Wave Power became the first developer to install a device at EMEC in August 2004 3. Their Pelamis P750 wave energy device was the first in the world to generate electricity into the grid system from offshore wave energy.
Funding for the UK's first wave farm was announced by the Scottish Executive on February 22, 2007. It will be the world's largest, with a capacity of 3 MW generated by four Pelamis wave energy converter machines at a cost of over £4 million.4 The funding is part of a new £13 million funding package for marine power projects in Scotland that will also support developments to Aquamarine's Oyster and Ocean Power Technology's PowerBuoy wave systems, AWS Ocean Energy's sub-sea wave devices, ScotRenewables' 1.2 MW floating rotor device, Cleantechcom's tidal surge plans for the Churchill barriers between various Orkney islands, the Open Hydro tidal ring turbines, and further developments to the Wavegen system proposed for Lewis as well as a further £2.5 million for EMEC itself.5
Tidal Power
The tidal site is at the Fall of Warness to the west of the Island of Eday in an area in which the tide flows reach 4m/sec (7.8 knots) at springs. There are four test berths at depths ranging from 25 to 50m.
The first developer to use the site is the Irish company OpenHydro, which installed a 250KW unit at the end of 2006. It provided power to the grid on May 26, 2008, the first tidal stream generator to do so. This is part of their programme to develop an array of 1MB turbines in Alderney in the Channel Islands in 2009.6 Lunar Energy have announced their intention to install a 1MW version of their RTT technology.7
