Abstract

The electricity transmission and distribution tariff policy of the second supervision cycle in China has formulated a much better electricity transmission and distribution tariff supervision system. In this context, the research on the risk related to electricity transmission and distribution tariff regulation faced by power grid enterprises is helpful for power regulatory agencies and business operators to identify and avoid risks in time and promote the sustainable development of electric power industry. Firstly, the risk evaluation criteria system is established. Secondly, a risk evaluation model based on the best and worst method (BWM) and cloud model for electricity transmission and distribution tariff regulation is proposed. Finally, the risk level of power transmission and distribution tariff regulation faced by four provincial power grid enterprises is evaluated. The validity and practicability of the proposed model in this paper are proved by the empirical analysis.

Highlights

  • With the more clarified on regulatory boundary and increasing force of regulation in China, the electric power grid enterprises are faced with a closed loop regulatory system and increasingly strict regulatory environment, which will face more uncertain risks

  • It is urgent to research the risks of electricity transmission and distribution tariff regulation for power grid enterprises, which can help the power regulatory agencies and business operators to identify and avoid risks in time and promote the sustainable development of electric power industry under the electricity transmission and distribution tariff regulation environment

  • It is of great significance to evaluate the risks of electricity transmission and distribution tariff regulation for power grid enterprises and to establish appropriate risk evaluation index system

Summary

Introduction

With the more clarified on regulatory boundary and increasing force of regulation in China, the electric power grid enterprises are faced with a closed loop regulatory system and increasingly strict regulatory environment, which will face more uncertain risks. Most researches on the risks faced by electric power grid enterprise focus on the power grid operation, investment and so on. Et al proposed that it was necessary to establish a reasonable feed-in tariff system for wind power and strengthen the commercialization and marketization of wind power operation management so as to cope with the operational risks faced by current power grid enterprises in the management of wind power projects[1]. The risks of electricity transmission and distribution tariff regulation for power grid enterprises have been rarely studied, especially that in China case
