This paper describes the Electrical Power System (EPS) for Gaia spacecraft. It generates a fully regulated bus of 28V +/- 0.5% in all mission phases, 28V +/- 0.1% over 6 hours under stationary conditions in science mode, which is distributed to the spacecraft users for 5.5 in orbit lifetime. The design characteristics of the EPS elements are described and a summary of the main performances is given.
