Calculation method of multi-regional power grid investment capacity based on debt-to- asset ratio

Under the background of the new reform and regulation of electric power enterprises' operation mode, the study on the investment capacity of an electric power enterprise is becoming increasingly urgent. At the same time, the enterprises are facing problems, e.g., it is difficult to allocate investment considering that electric power systems in different areas have different investment capacities. On this basis, an assessment method for the investment capacity of a multi-area electric power system is proposed based on debt - to - asset ratio. First, the comprehensive benefits are assessed. Then, the allocation coefficients are calculated by combining asset factors and performance factors, according to which the benefits are allocated. Accordingly, the investment capacities of electric power systems in different areas are calculated based on debt - to - asset ratio. Through the analysis of a case study of one city-level electric power enterprise, the investment capacity in the future is forecasted, which can provide reference for the investment plan of the enterprise.
