This work presents the energy auditing at Khao Leam Hydro Power Plant and explains the principles of energy conservation in the designated buildings and factories as well as the policy and the operational control to use energy efficiently. Energy auditing in designated buildings and factories is necessary fora building or factory, which wants to have a good energy management, reduce environmental impacts from energy production, plan the significant energy conservation and set up the energy consumption target. The preliminary energy auditing at Khao Leam Hydro Power Plant by the Department of Energy Audit Department, the Division of Efficiency Control, the Electricity Generating Authority of Thailand under the requirement of the Energy Conservation Committee of the Power Plant was investigated. The results showed that no improvement was required for the solar radiation reduction since the Overall Thermal Transfer Value and the Roof Thermal Transfer Value met the regulations of the Ministry of Science, Technology and Environment. On electricity savings, 3 countermeasures were proposed, i.e., conserving the energy in air coolers of three generators, using high efficiency air conditioning systems, and low-loss ballasts. Lastly, for the thermal energy aspect, no action was taken since no fuel and thermal energy was used in the main electricity production process. With the proposed improvements, the expected electricity of about 14,207,305 kWh/year could be saved, which costs about 22,106,568 baht/year. The capital cost is about 20,632,727 baht and the payback period is 0.93 year.
