The energy spectrum of high-energy cosmic rays measured using the Pierre Auger Observatory is presented. The measurements extend over three orders of magnitude in energy from 3 x 10^17 eV up to the very end of the spectrum and they benefit of the almost calorimetric estimation of the shower energies performed with the fluorescence telescopes. The huge amount of data collected with the surface detector allowed us to measure the spectrum in different regions of the sky with high precision.
We will present the results of the measurements together with a detailed description of the systematic uncertainties.
