• We report thermoelectric measurements of the low carrier heavy fermion compound URu<inf>2</inf>Si<inf>2</inf>at high fields up to 34 T and at low temperatures down to 500 mK. The field dependence of the thermoelectric power (TEP) and the Nernst signal shows successive anomalies deep inside the hidden order (HO) phase. The field position of these anomalies correspond to different changes in the Shubnikov--de Haas frequencies and effective masses around 12, 17, 23, and 30 T. These results indicate successive reconstructions of the Fermi surface, which imply electronic phase transitions well within the HO phase.
