Abstract:
To study the structure of consume electricity and propose to instruct a procedure, work instruction and user manual for electricity conservation. In Thailand, since 10 years ago, have been high trend to consume electricity due to the goverment has been encouraging investment in electronics in electronics industry which high consume electricity. In factory case study, since 3 years ago, have been high demand so they need high consume electricity. In this research, we study electricity conservation theory, manufacturing process, capacity and electricity consumption. In 2005, Specific Energy Consumption (SEC) of 2005 was 0.506 MJ/Unit (EU). We establish the electricity conservation committee and then develop energy conservation and energy saving procedure such as production control, implement VSD for HVAC. The SEC is 0.452 MJ/Unit that better than the same period. In this paper, we report procedure and work instruction by SPER that the firm can be enduring electricity conservation and helpful for electricity planning in the future.
