With increasing uptake of distributed generation into existing electrical network and the considering the importance of reducing the CO2 emission there is more emphasis on incorporating Demand Side Management (DSM) to the electricity network in the UK. Having a reliable model of domestic electricity demand is required in order to simulate any energy management control techniques for different household community sizes. The UK Time Use Survey (TUS) 2000 data [12] is used to create a model for electricity demand. By introducing new seasonal and monthly classes in processing the TU data, the effect of seasonal variation on active occupancy and electricity demand have been investigated in this work. Active occupancy is defined as the presence of residence at home when they are awake. Additionally an attempt has been made to calibrate the electricity demand model to monitored energy consumption of a particular dwelling at Creative Energy Homes (CEH).
