A study on the technical efficiency of power companies in the southern region of Vietnam
Published: July 30, 2026
Abstract
This study applies data envelopment analysis (DEA) approach to analyze the performance of power companies, mainly and typically in the southern region of Vietnam. The results analyzed for 21 power companies under the Vietnam Electricity’s Southern Power Corporation from 2011 to 2017 show that the average overall technical efficiency of power companies increased in the period from 2011-2017. In 2017, there are 8 power companies with an overall technical efficiency OTE score of 1 which are considered the most efficient among the companies under the study. The study also indicates potential input reduction and potential output addition, i.e. the potential to improve the overall technical efficiency of power companies.
