A Brief Talk on China's Research and Formulation of Transmission Price

Since there is currently no internationally reliable and fair transmission cost sharing method, the following general recommendations are given only for China's future research and development of transmission prices:

(1) The price of the transmission is based on the price of the two-part system. The latter requires all trading conditions to be mastered at all times, which requires advanced, costly computer systems. In addition, the use of "point" to "point" prices will discriminate against new Internet users. In the former case, the fixed transmission capacity of the transmission is paid according to the allowed transmission capacity, and the kitten cable is simultaneously paid for the variable transmission cost according to the actual network or the network power. The above described transmission losses and congestion costs are recovered through variable costs.

(2) A better method is to calculate the fixed cost and variable cost based on the long-term marginal cost of grid power saving. If you can't do this, you can also use short-term marginal cost to calculate. However, it must be considered that new investments have a significant impact on the marginal cost of grid savings. When there is a new investment, the marginal cost of power saving will be significantly reduced, so for a grid that is expanding, the node price is relatively unstable. Therefore, it is recommended that the cost of transmission be shared over a sufficiently long period of time.

(3) The power producer should share 50% of the transmission cost. At such a price, the power producer's site selection should be conducive to improving economic efficiency. If the transmission price is designed reasonably, the generators close to the users will increase their competitiveness.

(4) The price of transmission should be relatively stable in a period of time to facilitate the formation of effective long-term decision-making by power producers. In China, for a long period of time, do not use real-time electricity prices.

Because of the natural monopoly of transmission, it is necessary to regulate its business. The content of regulation depends on the separation of transmission companies and power generation companies. It is financial separation, separation of operation and management, separation of transmission and transmission services, or complete separation of property rights. At present, the regulatory content includes at least: planning and development of power grids; Operation and maintenance business; vacuum electrode transmission company financial status and return on investment; open transmission network business.

According to international experience, the regulatory functions and institutions of the electricity market should be relatively concentrated and independent. The current regulatory functions of electricity price and power infrastructure investment in China are planned and developed by the central and provincial governments, while the regulatory functions for power market operations are located in the economic and trade commissions of the central and provincial governments. In addition to regulatory functions, government departments at all levels have many policy functions. On the one hand, the regulatory functions of various government departments overlap, and the control overlaps with government functions; on the other hand, some regulatory functions are currently not undertaken by any department. After the commercialization of the electricity market, the regulatory functions of safety and quality standards should not be placed on provincial power companies.

The establishment of China's electricity market regulatory agencies should be weighed between the ideal regulatory model and the reality. It is important to clarify all regulatory functions as much as possible and to rationally distribute these regulatory functions between the central and provincial levels, as well as to take advantage of existing government agencies and their functional settings.
