- Three sites in Scotland and Ireland with a combined output of 60MW to utilise Lànstrøm tidal device
- Successful completion of four year technology test programme
- New company established to maximise manufacturing work in Scotland
ScottishPower Renewables today confirmed they are evaluating three separate coastal sites for the development of the world’s largest tidal stream projects. This historic milestone has been made possible by the successful trial of the world’s most advanced tidal turbine - Lànstrøm.
Two of the sites are being planned in Scotland, in the Pentland Firth and the Sound of Islay, with the third off the North Antrim coast in Northern Ireland.
ScottishPower Renewables expects planning applications to be submitted to the Scottish Government and Northern Irish Assembly in summer 2009.
Each site is being evaluated for with a view of installing between 5 and 20 tidal turbines. With each turbine having an installed capacity of IMW, this could lead to a combined output of 60MW – enough green energy for over 40,000 homes. Following planning approval, the projects could be operational by 2011.
All three projects are expected to deploy the Lànstrøm tidal turbine developed by Hammerfest Strøm AS, a company jointly owned by ScottishPower Renewables, StatoilHydro and Hammerfest Energi. The device’s name reflects the Norwegian and Scottish collaboration - being a combination of the Gaelic ‘làn’ meaning ‘full’ and the Norwegian ‘strøm’ meaning ‘tide’.
Keith Anderson, Director of ScottishPower Renewables, said:
“This is a historic day for the development of marine energy. The rapid technological advancement of tidal power has enabled us to progress plans for this substantial project which has the real potential to deliver significant environmental and economic benefits.
“Tidal power is completely renewable, being driven by the gravity of the sun and moon, with no carbon dioxide emissions, whilst being entirely predictable in nature. Scotland has the best tidal resources in Europe with the Pentland Firth alone containing enough tidal energy to meet a third of Scotland’s power requirements.
“Following significant research and development in Scotland during the 70’s and 80’s, the opportunity associated with the manufacturing of on-shore wind turbines was not realised. Tidal power now provides Scotland with another chance to become the global leader in a new renewable energy industry.
“These rapid advances have only been achieved with the support and encouragement of the Scottish Government – including its progressive system of strong financial support for tidal and wave projects”.
ScottishPower Renewables is part of the Iberdrola Group, the largest renewable energy provider in the world. Iberdrola have committed to investing €1.2billion in the development of renewables in the UK between 2008-2010. Beyond this, ScottishPower Renewables plans to have an renewable generating capacity of 1800MW by 2012.
The Lànstrøm is the most advanced tidal turbine in the world following an extensive and successful 4 year testing regime in Norway. The device will now complete final testing in Scottish conditions, ahead of full deployment of the technology at the tidal farms from 2011.
ScottishPower Renewables has invested in excess of £1m in Hammerfest AS and is represented on the company’s board. A new subsidiary company, Hammerfest Strøm UK, has been established in order to maximise the opportunity of manufacturing these todal devices in Scotland. This company owns global rights to manufacture and export the new tidal turbine thus creating substantial export opportunities for Scotland.
Einar A. Naess, Chairman of Hammerfest Strøm AS/UK, said:
“The development of our tidal turbine technology is based on modern sub sea technology used in the Barents Sea, combined with well known hydro power technology.
“Together with our Scottish partner, ScottishPower Renewables, we are now ready to take the technology to commercialisation and we want as much of this as possible to be in Scotland. Scotland is blessed with the best tidal stream resources in Europe but also benefits from the support of the Scottish Government who have identified the tremendous industrial possibilities in the coming tidal power industry. The Scottish Government also works with the industry to develop sufficient incentives both to maximise job creation possibilities and to meet the targets for renewable energy production.
“Hammerfest Strøm is looking forward to cooperating with our Scottish partners to achieve these goals.

Notes to Editors:
- The largest owners of Hammerfest Strøm AS’s are ScottishPower Renewables, StatoilHydro, the Norwegian oil and gas company, Hammerfest Energi, a power utility located in northern Norway, and Hammerfest Naeringsinvest. Their tidal technology has been extensively tested at 300kW scale over a four year period, in tidal waters at Hammerfest.
- The tidal power resource is estimated at some 150 billion kilowatt-hours per annum globally. The UK share has been estimated at 13 billion kilowatt-hours (Phase II UK Tidal Stream Energy resource Assessment, Black & Veatch, 2005), and over 80% of this is located in Scottish waters.
- Lànstrøm’s technology is a form of "tidal stream" power which can be distinguished from "tidal barrage" power as there is no need to impound the water. This is expected to bring significant environmental advantages by avoiding impacts on sensitive inter-tidal zones around the coast.
- Lànstrøm’s technology is best described as an underwater wind turbine, but with much shorter blades, and turning more slowly. The units are mounted on the sea bed and aligned to the tidal flow. Each device will generate around 1MW of output, and in future arrays of multiple devices are anticipated which could generate 50MW to 100MW each.
- The Scottish Government have taken a leading approach to stimulating the marine renewables market through support grants and a longer-term revenue support scheme. The Scottish Government has stated that "Scotland is uniquely placed to be a world leader in tidal power. We are home to the meeting point of two powerful seas and the Pentland Firth has been described as the 'Saudi Arabia of tidal power'. (http://www.scotland.gov.uk/News/Releases/2008/09/09111618)
- The Scottish Government have recently confirmed their intention to introduce increased funding for wave and tidal projects with multiple ROC’s (3 for tidal and 5 for wave). This will ensure that Scotland has the best support regime in the world for marine renewables.
