Ph.D. Candidate in Economics, Graduate Research Assistant

University of Hawaii at Manoa


I am a doctoral candidate in Economics and currently working as a graduate research assistant at UH-Manoa Department of Electrical and Computer Engineering. I am broadly interested in climate, energy, and development economics. Motivated by an interest in informing public policy, my work focus on analyzing and evaluating energy conservation programs, energy market efficiency, climate change impacts, and vulnerable population well-being. Before moving to Hawaii for my Ph.D. program, I was a lecturer in Economics at the Ho Chi Minh City Open University in Vietnam. I will be available for interviews for the 2021-2022 job market.

How efficient is the U.S. natural gas pipeline system?

To get approval from Federal Energy Regulatory Commission (FERC) on building a new interstate natural gas pipeline or expand a pipeline’s capacity, pipeline companies have to demonstrate market needs for capacity expansion by showing their long-term contracts with gas shippers for gas transportation. This practice has been criticized where both pipeline companies and shippers are affiliated entities. The reason is the inherent risk-shifting in such transactions whereby pipeline developers stand to earn a return above risk and captive utility customers are levied with significant reservation costs regardless of whether their gas utility uses the pipeline capacity. In Feb 2021, FERC issued a notice of inquiry seeking suggestions on what methodology and types of additional or alternative evidence should FERC examine to determine pipeline project need. This paper aims to contribute to the ongoing regulatory debate by providing a model-based project evaluation method for examining the efficiency of the current natural gas market in the contiguous U.S. and assess the need for an interstate pipeline project in the context of ongoing energy transition and decarbonization policies. The model built in this study is a linear programming model that minimizes the total cost of natural gas production, pipeline, and storage to meet the predicted U.S. domestic demand. The model determines the need for additional capacity of gas wells, storage, and pipelines to accommodate the gas flow between supply and demand regions. By contrasting the optimal outcomes with the observed outcomes and the total cost in each case, we discuss the efficiency of the current natural gas pipeline system.
