The quest for a non-zero electric dipole moment (EDM) in a non-degenerate system such as the electron, the neutron or the Hg atom is a powerful way to search for physics beyond the standard model in the CP violation framework, complementary to the LHCb experiment. So far, no evidence for such an intrinsic property was observed and the upper limit on the neutron EDM (nEDM), established in 2006 by the RAL/Sussex/ILL collaboration, is |d_n| < 3 x 10^-26 e.cm (90% C.L.) [C.Baker et al. PRL 97, 131801 (2006)]. The nEDM experiment at the Paul Scherrer Institute in Switzerland aims at lowering this limit at the 10^-27 e.cm level within the next decade. I will present the current status of the experiment, focusing on the fruitful 2015 data taking and discuss the prospects for the future.
