Samoa's government says close to 60 percent of the country's electricity supply is now being produced by renewable sources.
It says three private companies are providing solar power, complementing input from the Electric Power Corporation, which uses hydro, solar and wind power generators.
With the corporation driving towards a target of 100 percent renewable power generation by 2021, the government says more projects are in the pipeline.
These include a second wind energy project designated for Tiavi, on the hills behind Apia.
The eight megawatt project is part of a partnership with a private company that requires it to build the wind farm plus a hydro storage plant on Upolu.
When complete the wind farm will be the second in Samoa.
