| The typical daily load curve for households is well known from various studies. The above figure illustrates this with a chart from [Zimmermann_2012]. During the small hours of the night the load is low, with a steep increase in the morning when people get up and start their daily routine. After this rush hour a slight decrease and a minor peak around lunch time can be observed. The main activities only begin after four in the afternoon when inhabitants return home, cook meals, and start electronic entertainment equipment. \\ | The typical daily load curve for households is well known from various studies.

| In sample 01 it seems that the variability of electricity use differed somewhat in the two consecutive experiment phases but the general pattern of the median hourly share in the daily total appears to exhibit no significant change. The median curve largely follows the characteristics determined by other studies, e.g. [Zimmermann_2012]. There is no indication that daytime energy use had been incentivised in a significant way by the daytime price. \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ | In sample 01 it seems that the variability of electricity use differed somewhat in the two consecutive experiment phases but the general pattern of the median hourly share in the daily total appears to exhibit no significant change.

| In sample 02 it seems that the variability of electricity use is pronounced in this household and differed less than in sample 01 in the two consecutive experiment phases. The general pattern of the median hourly share in the daily total, however, still follows the average profile rather well. One notable difference, for both phases of the experiment is, that in this household the morning hump is more pronounced than the evening hump. If a change in user behaviour can be observed it is a shift of the energy use towards the evening but there are no signs for increased daytime energy use. | In sample 02 it seems that the variability of electricity use is pronounced in this household and differed less than in sample 01 in the two consecutive experiment phases.

| In sample 03 both the variability of electricity use and the hourly share during the daytime hours seem to have increased from one phase of the experiment to the next. One notable difference to the average profile, for both phases of the experiment is, that in this household the morning hump is more pronounced than the evening hump. In this sample significant signs for increased daytime energy use can be observed. \\ | In sample 03 both the variability of electricity use and the hourly share during the daytime hours seem to have increased from one phase of the experiment to the next.
