Peak demand, price elasticity and intrinsic flexibility from time use activities
Dr Jacopo Torriti, University of Reading, United Kingdom Peaks in electricity demand bring about significantly negative environmental and economic impacts. This is because if a vast number of users is consuming electricity at the same time, suppliers have to activate power plants with higher greenhouse gas emissions and higher system costs. In Europe, the residential sector is responsible for about one third of overall electricity demand and up to 60% of peak demand. During peak demand, electricity prices in wholesale markets could fluctuate from less than €0.04/kWh to as much as €0.35/kWh (Torriti, 2015). Whilst the volume of electricity demand relates to many factors (e.g. weather, type of appliances, types of building), patterns throughout the day are a direct reflection of people’s activities. A simple example derives from the substantial difference between residential electricity load curves for weekdays and weekends. During the same season the weather can be equal at the weekend compared with the weekday. Everything else remains the same between a day of the week and the weekend: building, appliances, fuel substitution, price of energy and appliance control, and Read more…
