| Abstract | Thailand government has pursued a policy under the New Industrialized Country (NICs) to enhance industrialization. The increasing economic growth and particularly in industrial sector resulted in rapid increase of energy consumption. EGAT has been facing problem with speeding up construction due to its underestimate power demand since the last few years. The situation became worse in the mid-1990 because of uncertainty of oil supply and increasing oil price due to Gulf Crisis. Cogeneration could be a remedy of these problems since it is more efficient and easy to install. This study focuses on the cogeneration potential in a polyvinylchloride factory at Map Ta Phut industrial estate. The cogeneration potential was investigated both in technical and economics aspects. The suitable cogeneration technology for this factory was found to be 10.2 MW gas turbine with heat recovery steam generator. This cogenerator should be operated with the steam-matching mode. From economic analysis payback period ls found about 2.5-4.5 years (depending on electricity price and fuel price escalation rate) and internal rate of return in the range of 25-60%. The cogeneratlon feasibility considering future plan of expansion of the factory was also investigated. The cogeneration system for the expanded plant should be 15 MW gas turbine with heat recovery steam generator. The cogenerator should be operated with the power-matching mode. Payback period for this system is found to be in the range of 2-4 years and internal rate of return in the range of 30-70%. |
