The principal contradiction facing Chinese society has evolved. What we now face is the contradiction between unbalanced and inadequate development and the people’s ever-growing needs for a better life. As power grids play a significant role in energy resource distribution and utilization, the quality of power grid development is the foundation of healthy social and economic development of China. This paper analyses the unbalanced and inadequate development of power grids. Firstly, current situation and problems of power grid development are analysed. Secondly, an evaluation system of unbalanced and inadequate development of power grids is built to quantitatively assess the development of power grids. The unbalanced development index system is composed of secondary indicators of unbalanced urban and rural grid development, unbalanced regional grid development and unbalanced load development. The inadequate development index system is divided into scale indicators, quality indicators, automation indicators and management indicators. Each secondary indicator is then further detailed into tertiary indicators. Then, a case study of provincial power grid is applied to prove the effectiveness of the proposed index system. Study results highlight some problems, for example, unbalanced transmission and distribution grid development, unbalanced urban and rural grid development, unbalanced regional grid development, inadequate distribution grid development, inadequate automatization etc. Lastly, future improvements and measures are pointed out.
