In order to promote the effective development of energy conservation and substantive advancement of electricity markets， this paper discusses the union implementation scheme of both terms from technology aspect. Firstly， energy conservation measures are studied， and then the energy conservation economical dispatch and electricity marketability methods on generation side are discussed emphatically. In the energy conservation economical dispatch， the generation priority is determined according to generation coal consumption， network losses， energy usage within power plant and pollution discharges and so on， and in the electricity market method， the generation priority is determined mainly according to market participants' diverse offer and grid losses. Furthermore， the union implementation possibility of the above two methods is studied， and a set of technical schemes are put forward. At last， the influence of the coal consumption， network losses， pollution discharges， market participants'diverse offer and so many factors on the generation sequence are analyzed qualitively and quantitively.
