History of WinWinD

1998-99 The development of the new wind turbine concept started together with ABB (Finland) and Metso Drives

2000 The company WinWinD was founded

2001 Pilot plant (1 MW) was taken into use

2002 Industrial production started

2002-03 Multi-megawatt turbine development and a pilot plant (3 MW).

Grid-friendly Electricity

Constant output above rated wind speed

Low fluctuations, even with partial power

Suitable for a weak grid

Operational also in a stand-alone mode

Electricity production is controlled by an IGBT AC inverter.

10

Cost-effective MaintenanceMinimised production stops

Maintenance friendly concept

fast on-site maintenance

exceptional long maintenance cycle of the components

Unique factory test of the power unit

RESULT:

Reliable wind turbine, high availability

Partnership Network

ABB (Finland), Metso (Finland) and others.

Well known component suppliers form the framework of our networked operations.

Continuous technology development investments in co-operation with our partnership network ensure that we retain the lead in this technology field.

Our aim is to have the highest local content possible.

Multi-megawatt Wind Turbine

WinWinD is developing wind turbines with greater output: 2,5–3 MW

2,5 MW for onshore/inland and 3,0 MW for offshore.

Slow rotation principles will be used.

Pilot starts late 2003.
