Brazil's wind power output hit 3,003 average megawatts (MWa) between December 1st to the 21th, marking a 50% year-on-year increase, according to preliminary figures released by the Power Trading Chamber (CCEE).
Wind farm contribution to Brazil's total power generation rose from 3.1% in December 2014 to 4.7% this year.
The data was published by CCEE in the latest edition of InfoMercado Semanal, a weekly newsletter for energy generation and consumption.
During the month, CCEE also observed an increase in the generation of power from plants running on solar power, at 3 MWa, and on biofuels, at 547 MWa, marking an increase of 104.3% and 0.3%, respectively. Biomass fell 4%, from 2,252 MWa to 2,163 MWa over the period in review.
Hydro power output also grew in December with an overall generation of 45,535 MWa.
While wind and solar contribution grew significantly, Brazil's electrical generation fell 0.9% year-on-year, with 63,809 MWa delivered to the National Interconnected System this month.
