With the durative and stable development of power market and the advancement of society, the power marketing strategies of our nation advance with the times.

Considering some factors affecting power supply cost, the models were established, the power supply costs of inhabitants, industrial users with voltage 110kV and with voltage 10kV were compared qualitatively, the power supply costs of the three kinds of power users were estimated quantificationally. A conclusion was obtained that the costs between inhabitants and industrial users were converted, the crossed equation exited, so it was necessary to actualize ladder- progressive electricity price.In recent years, power consumers got diversiform, consumers' demands to power quality enhanced gradually. Power load varied with temperature, etc. These factors made relevant different prices feasible. In the third chapter, the actualization of all kinds of active different prices was analysed in detail, the influence of the actualization of these electricity prices on market and the referrence to Zhejiang province's electricity price system.In the fourth chapter, with the correlative power data of Zhejiang, the market shares of province-class electric-power companies and user-owned power plants were analysed in detail.
