The former one has been operated for more than 22 years, while the latter is in commissioning phase. We target of the beam current on 500 mA. Thus, the power consumption increases higher than ever. Currently, the contract power capacities of the TLS and TPS with the Taiwan Power Company (TPC) are 5.5MW and 7.5MW, respectively. The ultimate power consumption of the TPS is estimated about 12.5MW. To cope with increasing power requirement, we have conducting several power saving schemes for years. This paper presents our latest power schemes, which include installation of power saving fan for the cooling tower, adjustment of supply air temperature according to the atmosphere enthalpy, replacement of old air conditioning unit (AHU), power consumption control by the operation of chillers, and power factor improvement.
