After 15 years of high­ly suc­cess­ful user op­er­a­tion, the Coun­cil of the ESRF are fund­ing an am­bi­tious 7 year up­grade pro­gramme (2009-2015) of the Eu­ro­pean Syn­chrotron Ra­di­a­tion Fa­cil­i­ty. In this con­text the ac­cel­er­a­tor com­plex will ben­e­fit from a num­ber of up­grades. Sev­er­al in­ser­tion de­vice straight sec­tions will be length­ened from five to six me­ters. The beam­line sci­en­tif­ic ca­pac­i­ties will be in­creased by op­er­at­ing some straight sec­tions in the cant­ing ge­om­e­try. New in­ser­tion de­vices will be built to ful­fill the re­quire­ments of the sci­en­tif­ic pro­gramme. The RF sys­tem also faces a major re­con­struc­tion with the re­place­ment of some klystron based trans­mit­ters by high power solid state am­pli­fiers and the de­vel­op­ment of HOM damped cav­i­ties op­er­at­ing at room tem­per­a­ture. The orbit sta­bil­i­sa­tion sys­tem sys­tem will be ren­o­vat­ed. This paper re­ports on the pre­sent op­er­a­tion per­for­mances of the source, high­light­ing the re­cent de­vel­op­ment, as well as the ad­vance­ment of the up­grade pro­jects.
