The Sidrap wind farm, located in South Sulawesi, is the first in Indonesia and the largest in the region, with 30 wind turbines on the farm and a capacity of 75MW.

The farm, which came on line in July and cost US$150 million (S$206 million), not only adds to the province's electrical reserves but also provides a source of renewable electricity, which can lead to reduced dependence on fossil fuels.

Another wind farm, called Tolo 1 and with a capacity of 72MW, is due to start operating this month in Jeneponto, South Sulawesi.

It is part of what investors hope will be a surge in wind and solar investment in Indonesia, driven by falling equipment costs, growing demand for electricity and policy changes by the Indonesian government.
