Study On Cost Accounting Of Transmission And Distribution Permit For Z Power Grid Company

In the "Several Opinions on Further Deepening the Reform of Electric Power System"issued by the State Council of the CPC Central Committee in 2015,it is clearly stipulated that in the future,the transmission and distribution price of our country will gradually transit to the principle of adding reasonable benefits according to the allowable cost,and be approved according to the voltage level.With the steady progress of electricity price reform,the strict level restriction of various parameters of allowable cost by the competent government departments has also brought new challenges to the operation and management of provincial power grid companies.Through reading the existing literature,I find that the current literature on electricity price reform in China mostly focuses on the interpretation of policy,and the analysis and comparison of the similarities and differences between domestic and foreign regulation modes.Although after the beginning of the new round of power system reform,there are some literatures which combine with the allowable cost and reasonable revenue pricing model,but mainly on how to calculate the transmission and distribution price reasonably according to the voltage level under this model.Practical research on the process of allowable cost accounting of provincial power grid companies is almost blank.Therefore,this paper uses the methods of system analysis,literature study and factor analysis to analyze the accounting process of allowable cost of Z Provincial Power Grid Company under the background of transmission and distribution price reform in detail,and puts forward relevant countermeasures according to the results of accounting analysis.The research contents are mainly divided into two parts:theoretical analysis and empirical research.Firstly,the part of theoretical analysis mainly analyses the existing literature.relevant basic theories and the composition and influencing factors of the allowable cost under the mode of cost-plus-income control,which lays the foundation for the follow-up empirical research.Then,in the empirical research part,based on the Provincial Power Grid Transmission and Distribution Pricing Method,and combined with the actual situation of Z Power Grid Company,the specific accounting of depreciation cost and operation and maintenance cost(including staff salary.material cost,repair cost and other costs)in the allowable cost of transmission and distribution price is carried out to distinguish the stock and increment.On this basis,the sensitivity analysis of key elements of allowable cost is carried out in combination with the pricing formula of electricity price,and its impact on the income of power grid companies is calculated and analyzed one by one.Finally,it is concluded that among the elements of allowable cost,the change of pricing depreciation rate has a significant impact on the income of power grid companies,followed by new fixed assets investment,while the impact of operation and maintenance fees is the smallest.Finally,based on the results of the allowable cost accounting analysis,from three aspects of cost management,asset investment and financial accounting to help Z Provincial Power Grid Company adjust its management strategy to adapt to market and policy changes,and can operate better under the new management and control mode of allowable cost plus reasonable income.
