This research is a study of integrated power management and risk management of the lighting system in petrochemical industries in the country, Thai. By technical feasibility studies It's possible to saraset archaeological site, and the possibility to manage the project from a technical analysis results showed that the tubes could be used in led the appropriate format to replace fluorescent tubes. Mercury and halide lai The quantity of light, still in the standard criteria. From the cost analysis throughout life found that energy-saving led bulbs can have on average 60 per cent. And tube metal HA lai 0.56 Thai baht per hour, and 0.303, respectively. Economic analysis of the project was changed to led bulbs for both chemical fertilizer factory, the number of bulbs, 7,651 tube considering the duration of 11 years of project implementation, there was found to be cost-effective, with the net present value of 12.22 million. Have a payback period of 4.0 years and provides an internal rate of return 26 per cent.3 Finally, likelihood analysis results in energy management and risk management of the lighting system.
