Five turbines

Five WES80 wind turbines were installed on Nusa Penida in 2005. The grid on the island is powered by a series of diesel generators with a peak load of 1.2 MW.

The 5 Hybrid turbines are installed in the diesel grid to reduce the consumption of diesel fuel. The average wind speed at the island is less than 5 m/s, but because the WES turbines have a low start up wind speed of 3.0 m/s, each turbine still generates an average of 135.000 kWh a year. Each turbine can reduce the diesel fuel consumption of the island by approximately 43.000 liters a year.

Lattice towers

The lattice towers and turbines have been installed without the use of a crane. A special hoisting rig with a hoisting boom and a winch have been used to lift the nacelle to the top of the lattice tower. The lattice towers have been locally fabricated in Indonesia.
