One of the key issues arising from extended smart metering roll-out across Europe is how the data obtained from the meters may be used to provide end users with important information on energy-saving advices. It is one of the main principles of demand side management (DSM). The investigation of the potential for demand side management to reduce peak load were evaluated in this study. Four-person household were surveyed with the aim to find out user activities within the house, in particular, the use of appliances. Two appliances - washing machine and dishwasher - were selected for assessing the potential for load shifting. The derived results show that due to washing machine and dishwasher load shifting peak load of a dwelling can be reduced in the average by 24% and 13,5%, respectively.
