Noimports from Venezuela took place during 2009. As a result of the El Niño event that developedat the end of the year, it is worth mentioning that the country generated during 200914,487 MW of thermal energy, an increase of 87.3% over 7,733 MW generated during 2008.ISAGEN, with Termocentro power plant generated 564.6 GWh, 3.9% of the total annual thermalgeneration of the Colombian System. This is an important share and means a considerableincrease compared to 31.3 GWh of thermal energy supplied to the System by ISAGENduring 2008, 0.4% of the country’s total.Compared to 2008, the Company’s energy generation decreased by 8.36% and its share inthe National Interconnection System – SIN– changed from 18.56% in 2008 to 16.54% in2009, due to the important increase in thermal generation during the last quarter of 2009caused by the onset of El Niño event.Contents Letter from the CEO Achievements2009Good GovernancePractices EvaluationCorporateManagementFinancial Management
