Title Low power mode electricity consumption in Hungarian households: how big is the problem and what is the potential to mitigate it?
Summary In the present thesis, the low power mode (lopomo) electricity consumption in Hungarian residential sector is analysed, based on spot and long-term measurements carried out in the sample of 95 households.
The average lopomo power in the households was found to be 30W. The average lopomo consumption was 0.65kWh per day, i.e. 236kWh per year. This represents 8.2% of the average electricity consumption in the survey sample.
The appliance categories with the highest share of lopomo consumption were audio-visual appliances and office equipment, representing together more than 80% of the average household lopomo consumption. Within the particular appliance type, set-top boxes, modems and routers were the appliances with the highest lopomo consumption. On the other side of the scale, cooking and cooling appliances formed only 4% of the lopomo consumption.
National lopomo consumption in the residential sector in Hungary was estimated to be 8 – 10% of the residential electricity consumption, which is comparable to the results from other OECD countries.
There were three policy options evaluated in terms of potential electricity savings. First, if all the appliances had lopomo power 1 Watt or less, more than 70% of the lopomo consumption could be saved, meaning decrease to only 3% of the electricity consumption. Very similar results were obtained in the case of behavioural potential (i.e. if all the appliances, where possible, were switched off or unplugged). Thirdly, economic feasibility of using standby killers was assessed. It was estimated, that by using two of these devices per household, the cost of the measure would be still two thirds less than electricity price.
To conclude, the lopomo consumption is an important, not negligible issue, which must be studied further. By the same token, the potential for savings is high and worth focusing on in designing energy efficiency measures.
