Brazilian wind farms registered an average capacity factor of 35% in January 2014, according to new data from Brazil's Power Trading Chamber (CCEE).
CCEE compared this with capacity factors
in China, the US and Spain, which in 2012 were 18%, 33% and 24% respectively.
According to Brazil's Wind Power
Association (Abeeolica) and other specialists, strong constant winds in
Brazil's northeastern and southern regions are behind the higher capacity
CCEE's report also showed that capacity
factors peak between August and November in Brazil, reaching 47%.
Turbines operating in the northeastern
regions registered the highest capacity factors in January. Those in the state
of Bahia reached 45%, followed by wind farms in Ceará, with 43% and then the
ones in Rio de Janeiro state with 42%.
The lowest capacity factors in January
were registered in the southern states of Paraná, Santa Catarina and Rio Grande
do Sul with 16%, 19% and 22% respectively.
The report also said that Brazil's
operating installed capacity reached 2.21GW in January 2014, a 20% increase
from the 1.81GW registered in January 2013.
The increase is a result the inauguration
of new wind farms since last year, and does not include plants that are
standing idle because of a lack of grid connections. A total of 89 wind farms
were in operation.
CCEE said that around 15% of all power
generated by wind farms in January was traded in the non-regulated market.
The rest was supplied through long-term
contracts in the regulated market or were sold to federal power company
Eletrobras through contracts signed during the Proinfa phase, Brazil's 1990s
programme to kick-start the renewable energy sector.
