In the historical background of adjustment economic structure and transform the mode of development, tariff regulation must assert electric enterprise and whole social interest so as to coordinate the devolopment, promote both saving energy and reducing emissions, decreaing gross coal consumption rate, and show the structural readjustment of the electric power industry,.strive to develop nuclear and renewable energy,etc. So the key to resolving power supply problem is to establish a reasonable pricing mechanism. With the rapid growth of market economy, it is required that China's power industry makes reform to establish a brand new power pricing mechanism and system. In the meantime, the study of price regulation lack practicalness and theroy. This dissertation study on the multistep residential pricing mechanism from the perspective of generation price, transmission/distribution price and sale side price, then the formation mechanisms, purpose, models and methods were proposed. The dissertation will not only having an important theory meaning and practice value to the pricing mechanism design and implementation, but also provide meaningful approaches for the healthy development of the electric power industry. The outcome is:1) Set up a price mechanism suitable for Chinese situation is very important by comparing electric price regulation of China and foreign contries. The theory and method of reform, restructure and diversification of property rights are all originated from western, so Chinese pricing mechanism is same as western's. the reform process also encountered the problem of market failure. The reform process in China also encountered the problem of market failure, therefore the introduction of western pricing mechanism will be an important step. However, China price mechanism is different from Western developed countries in the background, demands for reform, socio-economic development stage, China's pricing mechanism should be established considered stimulated devolopment, meet the requirement of fair and efficient, increased productive efficiency, prevented exceeding cross-subsidization. In the Pricing approach,the dissertation anatysis price cap and revenye cap of inspriring price regulation. Thepaper study the relation of the electric price level and the price index and acquire important the conclusion.2) This paper anatysis the problem of existing generation tariff and advance suggestion. In governmental pricing, uses the theory of regional yardstick competition to establish the government regulated pricing mechanism for the thermal unit in a regional area. So it will prompte optimize resource allocation and more generation for high-performance units. In market pricing because of information distortion, the regulator must regulate price settlement. For the existing characteristic of "dual track system" in the generation field, the pricing mechanism includes the settlement mechanism, which reflects the effective and reasonable of generation market, to further optimize the regional resource and to reduce ineffective investment. Whereas the lease system of pumped-storage units, the paper study and find it includes leasehold relation and agent relation. Tariff regulation must regulate the sharing of rental fee and overuse of the units besides rental fee.3) In the transmission section, the paper describes the transmission and distribution pricing structure (common network, dedicate network, access network) and pricing method according to current pricing policy and theory of ramsey pricing. A three-part tariff structure for common network is established with strong practicability and maneuverability.Reliability price reflects safety cost. Enery price shows variable cost. Remains express capacity price. Maybe three-part tariff changes to two-part tariff in the common network of lacking.4) In the residential sales price section, because of universal service, cross-subsidization be proviced. High-speed increasing in residential sales caused expansion of the cross-subsidization. The regulators must guid the residents for reasonal power and equitable burden sharing. The existing problems are careful analyzed. The improved multistep residential pricing model is proposed based on theory of ramsey pricing and demand elasticity. The model means keeping peak-valley price and carry out progressive increasing price. With the improved model, the price lever will be more effective to achieve energy conservation, environmental protection and social harmony. |
