Backgrounds

1. Project located on Högsåra island in Archipelago of SW Finland

2. Active local islanders as pioneers

3. New business possibilities to keep Archipelago inhabited and active

4. Utilize local pollution free energy production

5. Finland and EU policy to increase share of renewables and domestic production

6. Utilize vast nature reserve of near offshore wind conditions with installation on land

Why EU project

1. Challenging environment of Archipelago of SW Finland

– Rough terrain

2. 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

Innovation: Foundation

1. Counterweight from bedrock by anchors

2. Smaller construction and less material

3. No excavation below ground level

4. Transportation critical as continuous casting required

Innovation: grid connection

1. Connection to 20kV local distribution grid

2. Weak grid

– power limitations required

– compensation of reactive power

3. Special turbine/wind park control

4. Generator and Inverter from ABB Finland

5. Special filtering on transformer

6. Close cooperation with grid owner, Fortum

Measurements and follow-up

1. Meteorological measurements

– wind (3 levels), temperature, icing risk

2. Power performance

3. Load measurements on the foundation

4. Wind farm control in weak grid

Other aspects

1. Challenging environment

– Wind conditions studied

– Nature reservation areas nearby

– Visual aspects and noise

– erection on forested island

2. Public acceptance

– inhabitants and summer tourism

– local manpower and domestic production

3. Logistics

– ferry connection

– sea transportation

– narrow road through village

Conclusions

1. Three 2 MW gearless turbines on Archipelago

2. Partners gain valuable experience on

– remote conditions

– weak grid

– challenging environment

– new turbine technology

– test site for further needs

3. EU project a good way to demonstrate high risk innovations

4. Next towards FP7 !
