We participate in the Brazilian power market by selling standby availability to public utilities in regulated auctions and entering into bilateral contracts primarily with power distribution companies. We sold an average of 1,902 MWavg in 2008 compared to an average of 1,535 MWavg in 2007, a 24% increase. Our strategy also includes exporting energy to neighboring countries. In 2008, we exported 39.4 MWavg to Argentina and Uruguay.
Our gas-fired power plants have 4,550.0 gross MW of installed capacity, equal to about 5% of Brazils total power grid. We also control one oil-fired thermoelectric power plant with 31.8 gross MW of installed capacity. At year-end 2008, however, we had only 1,815 MW of commercial capacity at these plants due to gas supply constraints. Commercial capacity is the power-generating capacity that the Brazilian regulator allows us to sell as determined by a certification process.
The table below shows our installed capacity, certified commercial capacity and electricity generation for each of the last three years:
