That compares with R$213/MWh at the reserve auction last November and R$184/MWh at an A-3 auction in August.

"We wanted R$240 per MWh to offset rising higher financing costs, and inflation and foreign exchange rate fluctuations," Élbia Silva Gannoum, the executive president of the Brazilian Wind Power Association (ABEEólica) tells Recharge.

"But R$223 is adequate an shows that government is following a trend of covering higher costs,"

Still, Gannoum does not expect much wind power to be contracted because of low demand from distribution power companies.
