  1. HISP Högsåra Island Demonstration Project EWEC2007, Milano, 9th May 2007 Merja Paakkari, Hafmex Windforce Oy

  2. Backgrounds • Project located on Högsåra island in Archipelago of SW Finland • Active local islanders as pioneers • New business possibilities to keep Archipelago inhabited and active • Utilize local pollution free energy production • Finland and EU policy to increase share of renewables and domestic production • Utilize vast nature reserve of near offshore wind conditions with installation on land HISP project Merja Paakkari, Hafmex Windforce Oy

  3. Why EU project • Challenging environment of Archipelago of SW Finland • Rough terrain • Remote site with difficult access - behind two ferries • Logistics • Installation 3. Weak grid No ready solutions available, high risks • EU project applied for Spring 2003: HISP • Started Spring 2004 • Project ends Summer 2007 HISP project Merja Paakkari, Hafmex Windforce Oy

  4. Project partners • Hafmex Windforce Oy (coordinator), Finland • Harakosan Europe BV, The Netherlands (3. ABB, Switzerland – left the consortium Jan. 2006) 4. Roheline Ring, Estonia 5. VTT Technical Research Center of Finland HISP project Merja Paakkari, Hafmex Windforce Oy

  5. Innovation: Foundation • Counterweight from bedrock by anchors • Smaller construction and less material • No excavation below ground level • Transportation critical as continuous casting required HISP project Merja Paakkari, Hafmex Windforce Oy

  6. Innovation: grid connection • Connection to 20kV local distribution grid • Weak grid • power limitations required • compensation of reactive power • Special turbine/wind park control • Generator and Inverter from ABB Finland • Special filtering on transformer • Close cooperation with grid owner, Fortum HISP project Merja Paakkari, Hafmex Windforce Oy

  7. Measurements and follow-up • Meteorological measurements • wind (3 levels), temperature, icing risk • Power performance • Load measurements on the foundation • Wind farm control in weak grid HISP project Merja Paakkari, Hafmex Windforce Oy

  8. Other aspects • Challenging environment • Wind conditions studied • Nature reservation areas nearby • Visual aspects and noise • erection on forested island • Public acceptance • inhabitants and summer tourism • local manpower and domestic production • Logistics • ferry connection • sea transportation • narrow road through village HISP project Merja Paakkari, Hafmex Windforce Oy

  9. Conclusions • Three 2 MW gearless turbines on Archipelago • Partners gain valuable experience on • remote conditions • weak grid • challenging environment • new turbine technology • test site for further needs • EU project a good way to demonstrate high risk innovations • Next towards FP7 !
