Brazilian wind farms produced slightly less power in February due to a 2% decline in capacity factor. This is a result of seasonal changes in wind regimes.
According to data from Brazil's Power Trading Chamber, CCEE, total average power produced by wind farms fell to 734MW in February from 763MW in January. The total installed capacity of wind farms connected to the grid rose to 2.25GW from 2. 21GW.
The capacity factor of wind farms peaks at more than 40% from August to November every year. In 2013, capacity factors peaked at 47% in October, when installed capacity in commercial activity totalled 2.12GW.
The efficiency of wind farms also decreased year on year. In February 2013, the capacity factor measured by the CCEE reached 36%, compared with 33% in February this year.
Brazil's northeast accounted for about 70% of total wind production in February 2014, with an average capacity factor of 35.7%. The region accounts for 65% of all wind farms in commercial operation, or 1.46GW of installed capacity.
Wind farms in the northeast state of Bahia had the highest capacity factor of 45%.
Projects in Rio de Janeiro state registered the second-highest capacity factor of 39%, although it accounted for only 1.2% of total installed capacity, with 28MW.
The lowest capacity factor registered in February was in the state of Sergipe, with 17%, in the northeast.
The whole of Brazil's southern region registered an average capacity factor of 26.5%. This region accounts for 34% of the installed capacity, or 762MW.
