Energy-saving measures for further improving the energy-saving work in power plants after separation of Plants and Grids are presented

the principle of "Energy price analysis" being emphasized

and the formula of calculating "coal consumption rate in integrated cost" deduced. This method eliminates limitations of traditional thermodynamic analysis method

to combine the thermodynamics organically with the economics together. Taking the unit energy value as the basis

the added value and the profit of energy price during the time of energy transformation in power plants are analysed

including coal consumption of power generation

auxiliary power consumption rate

electrical energy price

and original price of standard coal etc.. The results of energy price analysis show

the price of produced energy is much higher than the price of fuel

therefore

the effectiveness of electricity-saving is much better than coal-saving.
