Abstract The Extra Low Energy Antiproton storage ring (ELENA) is an upgrade project at the CERN AD (Antiproton Decelerator). ELENA will further decelerate the 5.3 MeV antiprotons coming from the AD down to 100 keV and allow the experiments typically operating traps to increase the capture efficiency. ELENA features electron cooling for emittance control during the deceleration and therefore preserve the beam intensity and to generate bright bunches extracted towards the experiments. The ring has been completed with the installation of the electron cooler at the beginning of 2018. The electron cooler is meant to operate at an electron energy of 355 eV and 54 eV, corresponding to a pbar momentum of 35 MeV/c and 13.7 MeV/c. First observations of cooling have been observed at both energies, and decelerated ion beams with characteristics close to the design values have been obtained before the start of CERN Long Shutdown 2 (LS2). The latest results of ELENA commissioning will be presented, together with an overview of the project and status and plans.
