  The European Synchrotron Radiation Facility (ESRF) is presently midway through the Upgrade Programme Phase I (2009-2015), which concerns its infrastructure, beamlines and X-ray source. This paper reports on the present operation performance of the source, highlighting the more recent developments. In this context, 8 insertion device straight sections have been lengthened from five to six metres; two of them operating with canted undulators. The lattice of one cell has been modified for a further increase to 7 metres allowing the test of a mini beta optics and latter the distribution of cavities. A second cryogenic permanent magnet undulator has been completed, which gives a factor of more than 2 in flux at high energy. The booster klystron-based radio frequency transmitter has been replaced by high power solid state amplifiers. Out of three prototypes of HOM damped cavities working at room temperature which have been received and tested, one has been successfully commissioned with beam. Subsequent to the upgrade of the beam position monitor system, a new orbit feedback has substantially reduced the orbit distortion induced by ID gap motions.

  Four years after the launch of the Upgrade Programme, the ESRF is midway through its first phase (2009-2015) and has defined the objectives for the ensuing second phase. The first phase paved the way to a new generation of nano-beam X-ray beamlines fed by an X-ray source itself substantially improved in terms of reliability, stability and brilliance. The second phase envisions a major upgrade of the source to best serve the science case of this new generation of beamlines. In December 2012, the ESRF Council endorsed Management's proposal to launch the technical design study of a new 7-bend achromat lattice. This new configuration will allow the ESRF storage ring to operate with a decrease in horizontal emittance by a factor of about 30 and a consequent increase in brilliance and coherence of the photon beam. The increase will be substantially higher at X-ray energies larger than 50 keV.
