Barrow wind farm generates first power to the - Vattenfall

Immediate release19 August 2011Barrow wind farm generates first power to the gridVattenfall yesterday evening generated the first electricity from its wind farm offBarrow-in-Furness with Barrow’s Mayor hailing the achievement as an endorsementof Cumbria’s low carbon energy strategy.Vattenfall started offshore construction of the Ormonde Offshore Wind Farm in 2010and a little over a year later has exported power to the National Grid for the first timeat 7pm on Thursday, 18 August from turbine D1. When finished the 30-turbine,150MW, wind farm should generate enough power every year to meet the equivalentelectricity needs of around 100,000 UK households.David Hodkinson, Vattenfall’s Country Manager, said: "The first production ofelectricity from our 30-turbine Ormonde Offshore Wind Farm is a great achievementfor our team and suppliers. Some of the electricity will be finding its way to Barrowthrough the national grid, forming another bond between the Vattenfall and the localcommunity, adding to those we have already established including local job creationduring construction and over the operating lifetime of the project. We are also proudthat Ormonde has supported UK jobs further afield, through foundationmanufacturing, wind turbine pre-assembly and engineering and project support.Ormonde is the first commercial scale project to use 5MW wind turbines onfabricated steel 'jacket foundations', and sets the scene for the large-scaledeployment of such technology in the rapidly expanding UK offshore wind market.”He added: “Ormonde Offshore Wind Farm is the third Vattenfall project in UK watersto generate green, clean electricity for UK consumers. We are pleased to have madegood progress on this cutting edge engineering project and by the autumn we hopeto be generating power from all 30 REpower turbines.”Councillor John Murphy, Mayor of Barrow-in-Furness, said: “Here in Barrow-in-Furness we are world renowned experts in engineering and obviously we welcomethe opportunity for more jobs. Renewable energy is essential for our future and thesustainability of future generations. Vattenfall’s Ormonde Offshore Wind Farmendorses our viability as being part of the Energy Coast.”Vattenfall’s vision is to be a leading European energy company. Vattenfall’s main products are electricity and heat. Today, Vattenfall generateselectricity, produces heat and supplies energy to several million customers in the Nordic countries and northern Europe. The major customersare industrial plants, energy companies, municipalities, property companies and housing associations. For further information, please see1www.vattenfall.com.

Charles Hendry MP, Minister for Energy at the Department for Energy and ClimateChange, said: “I am pleased to hear that the turbines at the Ormonde offshore windfarm have started to supply clean, green, home-grown electricity into the grid. This isa real milestone for the company and the people of Barrow-in-Furness and I congratulateall involved for their efforts.“The involvement of Burntisland Fabrications and Harland & Wolff makes this a realsuccess story for the UK offshore wind supply chain.”Vattenfall is currently working to ensure that Ormonde Offshore Wind Farm is fullycompliant with the code that governs the operation of the National Grid. This is beingdone whilst Vattenfall commissions the thirty wind turbines that make up the scheme.However, it is likely that the compliance exercise will be completed later than fullcommissioning and this may result in reduced output for a short period.Vattenfall’s Ormonde Offshore Wind Farm is using REpower’s 5M wind turbines andall wind turbines have now been erected.http://www.vattenfall.co.uk/en/ormonde.htmhttp://www.britainsenergycoast.com/EndsPhotographs of Ormonde Offshore Wind Farm are available on request.Contact: Jason Ormiston, Vattenfall, Head of Media Relations07794524801; jason.ormiston@vattenfall.comNOTES TO EDITORSAbout VattenfallVattenfall is a leading European energy company. It is Europe’s sixth largest generator of electricityand largest producer of heat. Its major customers are industrial plants, energy companies, municipalities,property companies and housing associations across northern Europe. Vattenfall currently operates686MW of offshore wind capacity around Europe, including Thanet Offshore Wind Farm, theworld’s largest. It also operates 526MW of onshore wind across Europe, including Edinbane on theIsle of Skye.About Vattenfall’s Ormonde Offshore Wind FarmThe Ormonde Offshore Wind Farm, located 10 kilometres off Barrow-in-Furness in the Irish Sea willinclude 30 wind turbines totalling 150MW of installed capacity capable of meeting the equivalentannual electricity demand of more than 100,000 UK households. Ormonde Offshore Wind Farm hasbeen under construction since May last year with works offshore commencing May 2010. Installationof the wind turbines should be completed in the second half of 2011.Vattenfall’s vision is to be a leading European energy company. Vattenfall’s main products are electricity and heat.

Vattenfall started works to lay the export cable which will carry green electricity from the wind farm toshore in January this year and in July last year it completed the installation of 31 foundations for thewind turbines.About the REpower 5MWith a rated output of 5 megawatts and a rotor diameter of 126 meters, the 5M is one of the largestand most powerful wind energy turbines in the world. The rotor consists of three rotor blades, eachone 61.5 metres in length, and covers the area of two soccer fields; the nacelle is the size of twohouses. Two REpower 5M were commissioned in 2007 in the Beatrice demonstration test field in theUK. Six REpower 5M are also installed in the German test field alpha ventus.Project FactsNameOrmonde Offshore Wind FarmNumber of turbines 30Turbine capacity5MWTotal installed capacity150MWHomes equivalent production >100,000Water depth – low tideAround 17 to 21 metresWater depth – high tideAround 26 to 30 metresFoundation typeSteel jacketArea of wind farm 8.6km 2Distance from shoreAround 10km from Barrow-in-FurnessTip height (from sea level)153mHub height90mRotor diameter126mTotal weight of turbine661 tonnesWeight of rotor and hub125 tonnesWeight of nacelle315 tonnesWeight of towers221 tonnesCables to shoreOneLength of cable to shore 41,700mCable landfallHalf Moon BayDistance from cable landfall to substation 2,800mSubstationHeyshamVattenfall’s vision is to be a leading European energy company.
