Power regulator Aneel authorised operations to begin after the completion of tests carried out since mid-June.

The 14 wind plants are located in the northeastern state of Bahia and sold their power in Brazil's 2009 reserve auction.

On 1 June, Chesf said it had concluded the complex's link to the Igapora II substation after investing R$71m ($32m).

The wind plants have been standing idle since 2012.
