Alstom, SSE Renewables join to develop wave energy farm in Scotland

Orkney, Scotland, January 17, 2012 — Alstom and the leading Scottish marine developer SSE Renewables have signed a new joint venture agreement to develop the Costa Head Wave Project, an up to 200 MW wave energy site located north of mainland Orkney, in The Crown Estate's Pentland Firth and Orkney Waters Strategic Area.

Alstom and SSE Renewables will work together to obtain the necessary permits and intend to populate the site with AWS-III wave energy converters, a technology currently under development by AWS Ocean Energy Ltd, in which Alstom acquired a 40 percent equity share in June 2011.

The Costa Head site is located in water depths of 60 – 75m about 5km to the north of Orkney Mainland. SSE Renewables and Alstom propose to carry out detailed site surveys and an environmental impact assessment, to develop the site with an initial phase of around 10MW, before moving on to install the full site capacity.

Established in 2004, AWS Ocean Energy is focused on the development and delivery of its AWS-III wave energy converter, a floating device with a rated power output of 2.5 MW. A 1:9 scale model of the AWS-III was tested in Loch Ness in 2010.

Full scale component testing will commence in 2012 with the support of the Scottish Enterprise-administered WATERS fund (Wave and Tidal Energy: Research, Development and Demonstration Support), with a full-scale prototype planned for deployment at the European Marine Energy Centre in 2014.

Wave energy is a widely distributed renewable resource worldwide, with an estimated potential market of 200 to 300 GW. Its proximity to densely populated regions of Europe and North America make it an attractive new source of renewable energy.

The AWS-III technology consists of a multi-cell array of flexible membrane absorbers that convert wave power to pneumatic power through compression of air within cells that are inter-connected. Turbine-generator sets are provided to convert the pneumatic power to electricity.
