Energy balance is critical to guarantee the energy efficiency in aluminium electrolysis. However, to satisfy the electricity and sometimes the metal market needs, a wider operational energy input window is required. This would require large scale adjustment of input power and heat loss, if such a thing is possible. The associated wider cell operational window would need to be matched to flexible energy changes without alumina concentration problems. Side ledge control is also a challenge under such a flexible energy input scenario, and the bath chemistry will be changed by the ledge dynamic behaviour in conventional cryolitic baths. Thus, observations of the bath behaviour and heat transfer rates in the cell system are necessary in order to understand the limits of long term power adjustment.In this paper an analogue laboratory experiment is proposed, to model the industrial cell system and allow prediction of the effect of large scale power shifts.
