The Optimization of Basic Electricity Charges for the Two-part Electricity Price Based on Seasonal Demands

As the electricity market evolves, the method of charging basic electricity fees must adapt to continuously updated policies and market demands to optimize power cost management. This paper aims to study and optimize the basic electricity fee charging methods under the two-part tariff model, providing economical electricity solutions for power users. Firstly, the development of the two-part tariff model since 2015 is analyzed, highlighting its impact on users' electricity bill structures. The study explores the traditional single charging mode based on supply capacity, as well as more flexible charging methods combining contract maximum demand and actual maximum demand. Methodologically, a quarterly adjustment cycle is introduced, proposing a billing method that complies with existing two-part tariff policies. By establishing a mathematical model, the impact of different billing methods on annual electricity costs is simulated. By adopting different billing methods during peak and off-peak electricity periods, users can achieve significant cost savings. This seasonally adjusted billing method not only meets policy requirements but also provides an effective cost management approach for power users, helping to improve the efficiency of the electricity market and the economic benefits for users.
