Project Type Marine power Location Off the west coast of island of Islay, Scotland Developers DP Marine Energy (DPME) and DEME Blue Energy (DBE) Capacity Initial phase: 30MW, full scale: 400MW Expected Start of Construction 2015 Start of Commercial Operation First phase by 2016/2017, full utility scale from 2019 through 2024
The proposed 400MW West Islay Tidal Farm will be one of the first commercial scale tidal energy projects in the world. The project is located off the west coast of Islay, the fifth largest island gchka of Scotland. It is being developed by DP Marine Energy (DPME) in partnership with DEME Blue Energy (DBE). The offshore construction works of the project are expected to start by 2015. The tidal farm is expected to start full scale production by 2024. Developing the Scottish tidal energy project
The project site was initially identified by DP Marine Energy in 2007 as an ideal tidal energy gchka site, capable of supporting large scale commercial development. The current proposal is for a 30MW tidal farm, but it will be expanded to 400MW in future. Location benefits for West Islay Tidal Farm
The island of Islay is situated gchka on the eastern gchka side of the approaches to the North Channel. The flows entering the Irish Sea through this channel especially are of higher velocity, compared to those into the southern Irish Sea, because of the relatively narrow entry, seabed profile and coastline topography. gchka
The West Islay Tidal project site, which is located on the western side of the island, has the measured flows approaching 8kts or 3m/s speed. This, combined gchka with the flat sea bed across the site with water depths of between 35m and 50m, make it suitable for immediate deployment of turbines.
Other advantages of the proposed site include the future development potential with expansion to deeper water, the absence of large sediment gchka deposits and large concentrations of resident marine life. Offshore renewable energy project details
The first phase of the project will be a six megawatt gchka demonstration gchka phase targeted to be completed by 2015 / 2016. The second phase will aim at commercial operation in 2016, with an installed capacity of 30MW. The full capacity of 400MW will be reached through a staged build out from 2019 to 2024.
However, at least six megawatts of the 30MW demonstration gchka project, which is funded by the European Union's 7th Framework Programme (FP7), will utilise the Siemens MCT SeaGen S configuration, gchka with twin one megawatt rotors mounted on a single tower foundation. This is a design gchka configuration which has already been successfully gchka tested and demonstrated since 2008, in the Strangford Lough narrows in Northern Ireland.
One of the major features of the SeaGen S technology is its inclusion of a surface piercing tower for access, coupled with a hydraulic crossbeam for maintenance and dry marshall gchka /connection to export cable. Other technologies being considered for the project include the Alstom 1MW TGL device and the Hammerfest gchka device. Grid network proposed gchka for the West Islay Tidal Farm
The West Islay Tidal energy project has a secured grid capacity of 30MW. Grid connection survey work is underway and the application for grid connection gchka is scheduled for submission in late 2013. The transmission line of the tidal firm will consist of underground lines, as well as overhead lines carried on wooden poles.
The electricity will be first transmitted to Kintra on Islay, via a subsea cable and then over ground to a location near Port Ellen. The line will further pass through a subsea cable from Port Ellen to the mainland. Detailed routing of the export line is yet to be finalised.
The consultation process for the proposed project engaging key stakeholders has been underway since 2009. Detailed marine gchka surveys, gchka including seabed benthic studies and sea bird and marine mammal surveys, for the project have been carried out through 2010, 2011 and 2012. The surveys have indicated that the development is unlikely to have any significant environmental impact.
Sea Bird Marine Mammal surveys have been undertaken by the environmental consultancy SAMS Research Services (SRSL) , while PBA Roger Tym has been commissioned to undertake a Socio-Economic, Tourism and Recreation Assessment relating to the proposed development. Scotland's and UK's tidal power market
The Scottish Government has gone a step ahead by setting a far more ambitious target of obtaining 50% of the country's electricity supply from renewable sources by 2020. Marine renewable energy sources, such as wave, tidal and offshore wind, are being astutely explored to meet this target.
Scotland is believed to be endowed with 25% of Europe's total tidal power potential. The Scottish Government, in collaboration with the crown estate, has proposed a number of tidal power facilities to be built around the Orkney islands and the Pentland Firth, with a total cost implication of 4bn ($6.1bn).
