A Cost-effective Wind Turbine for the Present and Future The newcomer to the field, WinWinD, has created a WWD wind turbine, which offers the most cost-effective production throughout its total life, combined with the lowest operating costs.

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).

Case: Oulu Energy 1 MW wind turbine, WWD-1 Operational in Oulu, Finland. Since autumn 2001. Excellent results have been achieved.

Background of WinWinD Companies behind WinWinD Powest Oy A subsidiary of the largest power company in Finland, Pohjolan Voima Oy Head Future Technologies Oy Venture capital company, member of the Head Team The strong ownership provides the solid basis for the carrying out of wind power projects also on a large scale.

Optimal Energy Production An automatic control system controls the generator and network optimises energy production High efficiency even with low wind speeds

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.

Cost-effective Maintenance Minimised 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.
