ScottishPower Renewables is part of Iberdrola, the world’s largest wind energy developer, with an operating portfolio of over 14,000 megawatts (MW) (as of March 2012). ScottishPower Renewables is responsible for progressing Iberdrola’s onshore wind and marine energy projects in the UK and Ireland, and offshore windfarms throughout the world, managing the development, construction and operation of all (current and potential) projects.
In May 2012, the company’s second-generation Pelamis Wave Power device – the P2 – was deployed at EMEC’s wave test site for the first time on an adjacent berth to E.ON’s P2 device, as part of a unique joint working arrangement between the two renewable energy developers to maximise learning from operating and maintaining the machines as a wave farm. The machine is based at Lyness when not deployed on site.
The 750kW P2 comprises five connected sections which flex and bend in the waves. This movement is harnessed by hydraulic rams at the joints, which in turn drive electrical generators located inside the device. The device is 180 metres long, four metres in diameter and weighs approximately 1350 tonnes.
The experience gained from this project will play a vital role in ScottishPower Renewables’ plans to install 66 Pelamis machines in a 50MW project off Marwick Head in Orkney (to the north west of the Billia Croo wave test site), for which an agreement for lease has been awarded by the Crown Estate.
Whilst the P2 machines remain in Orkney, in November 2014 Pelamis Wave Power appointed an administrator to assess the options for future development.
