The Vergnet GEV HP 1MW is a two-bladed turbine concept with different versions available for high, medium and low wind-speed conditions.

The GEV HP uses a pulley system that enables the operator to detach and lower the upwind half of the nacelle. The aim is to allow the turbine to be installed in cyclonic regions.

Additionally, Vergnet says the lowering system allows for easy blade maintenance.

GL’s certification verifies the turbine complies with Class III standards for load, strength and safety.

The hub height goes up to 70 metres for low and medium wind-speed conditions. The rotor diameter is 62 metres.

The turbine, which was launched in 2008, is being installed on sub-Saharan Africa's biggest wind-power project — a 120MW installation at Ashegoda in Ethiopia's Tigray province.
