Why does the power grid company have to pay a part of the electricity fee to the electricity sales company?

First of all, you should explain which province you are from. At present, the trading rules in different provinces are different, but as far as settlement work is concerned, it is generally the trading center that makes settlement. I understand that when you say that the power grid company pays the electricity sales company, you mean that the trading center is paying, because the trading center belongs to the power grid (not yet independent at this stage), so you think the power grid is paying. In fact, for example, in a province with a non-transmission and distribution price model (such as Guangdong), the fee paid by the trading center to the power sales company = the long-term cooperation income you bought from the power plant+the bidding electricity income in the bidding market-the deviation evaluation fee-the fee paid to the customer by the power sales company according to the agency contract. So you see, the money actually belongs to the power plant and is paid to you through the trading center, which has nothing to do with the power grid from beginning to end. As for the mode of transmission and distribution price, I will write it when I have time. There is no such situation that the power grid pays the electricity sales company. Not to pay the electricity bill, but to return the difference. Take the rules of Guangdong Province as an example. The settlement methods of the power plant side, the user side and the power grid remain unchanged. The power grid company still pays the grid-connected electricity fee to the power plant (the profit part of the power plant needs to be deducted), and the user pays the electricity fee to the power grid (the part that should be returned to the user is deducted). The actual electricity consumption expenses of the users represented by the electricity sales company are still paid directly by the users to the power grid company. At this time, the power selling company is equivalent to the user, but because there is no actual electricity consumption, only the difference is returned, which is manifested as the cost paid by the power grid company to the power selling company. According to an article, three companies received electricity charges in the same batch, and the other two were Guangzhou Suikai Power Co., Ltd. and China Resources Power (Guangdong) Sales Co., Ltd., both of which were in the first batch of electricity sales catalogues. Managers of China Resources and Shenzhen Electric Power said that this is related to the business content and accounting efficiency of the enterprises themselves. "A wrong score will be countered by the power grid." The core team of Shenzhen Power Company is very familiar with the electricity bill settlement. China Resources has more than 150 customers, and the team stayed up for several days and nights, calculating every data. Open ears because most customers are in industrial parks, and the settlement is relatively simple. In addition, because the procedure of electricity bill settlement in Guangdong power grid is to receive invoices first and then pay checks, the imperfect financial system of power sales companies will also affect the progress. The electricity bill settlement includes the electricity bill returned by the long association in1-May and the electricity bill returned by centralized bidding in March-May. The electricity bill settlement of large users has been completed. The electricity fees returned by other power sales companies are still under review and settlement, and will be distributed in the future.
