In 2019, State Grid Corporation proposed the strategic goal of “three-type, two-network, world-class”, requiring all units to focus on the company’s investment effectiveness and focus on promoting the high-quality development of the company and the power grid. Based on the analysis of the electricity reform policy and the company’s strategy, this paper establishes an effective asset investment performance evaluation index for the three-tier power grid enterprises in provinces, cities and counties. Through the research on the quantitative method of indicators, a three-level evaluation model of provinces, cities and counties was established to support the evaluation of investment effectiveness of power grid enterprises. This paper takes the province, city and county three-level units as an example, and extracts data to measure and verify. The evaluation results objectively reflect the effectiveness of power grid assets investment of power supply companies at all levels, and propose investment management based on the calculation results.
