Accompanying to the construction of smart grid, it brings a variety of user electric equipment, and the quality of user electric service demand is also increasing year by year. The user electricity equipment evaluation is not only beneficial to the operation and maintenance of the power grid, but also affects the bidirectional interaction of function demand to the power grid and customer. This paper put forward the evaluation index system of the user electrical equipment based on the balanced score card. Firstly, the user definition, category and classification of the user electrical equipment was introduced. Secondly, from the three aspects of the energy efficiency evaluation, safety monitoring and demand response, the evaluation index system of user electrical equipment was expounded. Finally, in order to calculate the index weight value considering the input data uncertainty, it expounds the interval entropy method for the evaluation index system, analysis the resident power equipment as a case and expects to scientific, complete and systematic to evaluate user electrical equipment.
