ET-00-21 A thesis submitted in partial fulfillment of the requirements for the degree of Master of Engineering Thesis (M.Eng.) - Asian Institute of Technology The discovered natural gas was firstly begun the Gulf of Thailand in 1973. The gas utilization has been developed following with the Thai economic growth. Petroleum Authority of Thailand (PTT), has responsibility for petroleum energy supply and security for twenty-six years. PTT has been the big player in the natural gas industry and it also acts as the sole purchaser, transporter and distributor of natural gas to handle all industrial and commercial aspects of the petroleum business. In this study, the tariff on the gas transmission pipeline of Thailand is set by the expost simulation based on four models: the existing tariff setting as called cost of service model and incentive-based regulation (price cap regulation model, revenue yield cap regulation model, and combination model. The last three models are adjusted by inflation index and productivity improvement productive factor (CPI-X). Furthermore, the partial productivity measurement and Data Envelopment Analysis (DEA) are the important efficiency measurements to evaluate the operation efficiency of natural gas transmission and distribution system for PTT and Korea Gas Corporation (KOGAS). It was found that the price cap regulation is also suitable for implemented in the all tlu·ee-zone tariff rates in the long term. However, the combination model is reasonable for the tariff setting in the short term although its tariff profile is not smooth because of the volume of gas sold decrease at the end of project. For the productive efficiency analysis, the DEA model is the practice for benchmarking total efficiency for all Decision-Making Units (DMUs) of PTT and KOGAS while the P';lrtial productivity measurement performed by the key performance index (KPI) compares their efficiencies in case by case. From historical data, PTT was operating in efficiency frontier for all Decision-Making Units (DMUs). From DEA and partial productivity models, it is observed that both PTT and KOGAS have high performance through all DMUs. The outcome of DEA and productivity measurement can be used as the tools for control and evaluation of past accomplishments as well as the tools to aid in theirs planning future activities.
