  The ESRF, the first third generation synchrotron radiation source, opened its first beamline in 1994 and has been continuously developed since then to satisfy the user community. However, the need arose to make a major upgrade of the infrastructure and accelerator complex in order to fulfil the request for new scientific applications*. The experimental Hall will be expanded and half of the beamlines reconstructed. The storage ring lattice will be modified to provide space for longer as well as a larger number of insertion devices. New insertion devices will be developed possibly based on in-vacuum permanent magnets at cryogenic temperature. The electron beam positioning system will be rebuilt to provide a higher photon beam stability. The RF system will face a major reconstruction with a new type of RF transmitters and HOM damped cavities allowing stable operation at a ring current of 300 mA without feedback. The injector system will be upgraded to operate the 16 and 4 bunch fillings in the top-up mode in order to increase the average current and obtain a higher photon beam stability.

  The ESRF has been operating for a period close to fifteen years and is now looking towards an ambitious upgrade programme for the coming ten years. This paper reports on the performances achieved today with the ESRF storage ring, as well as developments accomplished and projects underway. These include a new filling mode for pump and probe experiments, the evolution of insertion devices, developments to improve beam stability, in particular transverse and longitudinal multibunch feedbacks, and the current increase from 200 to 300 mA. The upgrade of the lattice to accommodate longer straight sections and the new High Quality Power Supply system will also be presented. The machine reliability and the most important failures will be discussed. Finally, the use of an electronic logbook in routine operation will be presented, and the status on the control system including TANGO collaboration given.
