| Title | Analysis of electricity consumption patterns in Hungarian households |
| Summary | This work presents the results of the analysis of electricity consumption patterns in Hungarian households using data collected by REMODECE project (Hungary). High-resolution data (10- min records) from individually monitored appliances and light sources in 75households between 2006 and 2008 was processed. The obtained annual electricity consumption of the average Hungarian household was 2117kWh/year (present state). Cold appliances (44%), lighting (18%) and home entertainment (11%) are the end uses with the highest share. These end uses are in general, characterized by appliances with both high electricity consumption and high penetration in households. The analysis of the typical day (24-period) revealed two main patterns: appliances with defined periods of high consumption (e.g. TV sets between 20:00 and 00:00) and appliances with relatively constant electricity consumption during the day (e.g. modems and set top boxes). ICT equipment was selected to analyze power consumption in different modes: LP1 (off mode), LP2 (standby) and normal mode. For TV sets and computers up to 45% of the electricity consumption in a typical day occurs in LP1 and/or LP2 modes. For the rest of appliances it is above 90%. The combined share of LP1 and LP2 in the final electricity consumption of the average household was 3.2% (66.5kWh/year). This value is lower than the obtained in previous studies. Potentials for electricity conservation were identified and assessed comparing the consumption in the present state with the one using energy efficient equipment. Savings of up to 946kWh/year were obtained (46% of the consumption of the average household). Freezers, fridges and lighting were the appliances with the highest potential for electricity conservation. This savings can represent a reduction of up to 1618Kt of CO2/year. |
