A parametric analysis of domestic electricity consumption patterns in Ireland

This paper reports findings from a study of electrical load profiles obtained from a survey of a representative cross section of approximately 4,000 Irish dwellings. Electricity demand was recorded at half-hourly intervals for each dwelling over a six month period from 1st July 2009 to 31st December 2009. Descriptive statistics are shown for each electrical parameter such as mean, maximum demand, load factor and time of use (ToU) of electricity consumption. The mean power demand and daily mean load factor of the sample was 0.512 kW and 23.43% respectively for all dwellings over the monitoring period. A mean daily maximum demand of 2.5 kW was recorded for the sample. The most frequent ToU for maximum and minimum electricity consumption over the monitoring period was 18:00-18:30 and 06:30-07:00 respectively.
