Högsåra Island Demonstration Project
HISP

• EWEC2007, Milano, 9th May 2007

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

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

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

Innovation Foundation

• Counterweight from bedrock by anchors
• Smaller construction and less material
• No excavation below ground level
• Transportation critical as continuous casting
  required

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

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

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

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 !
