Residential Electricity Demand: Peaks, Sequences and Markov Chains

Funded by: EPSRC

Partners and stakeholders:

Association for Decentralised Energy, Bloomberg New Energy Finance, E-On, Kiwi Power



Peak electricity demand can cause imbalances between demand and supply with negative impacts on system costs and the environment. Understanding what constitutes peaks is about studying the timing of electricity demand and how it relates to what people do. Whilst there is information about the aggregate level of consumption of electricity, little is known about residential peak demand and what levels of flexibility might be available. REDPeAk will fill this gap.


The aim of REDPeAK is to understand which activities constitute peaks in residential electricity demand. In this project we investigate the role of synchronisation of activities and sequences of activities in shaping electricity demand. The project will analyse 10-minute resolution time use activity data from the UK Office for National Statistics Time Use Survey with a view to derive information about occupancy and synchronisation of activities. Markov chains will be used to model load profiles in combination with appliance-specific parameter data. REDPeAk will cluster respondents according to sequences of activities.


Public Lecture: ‘Sooner or later: Shifting the timing of electricity demand’

Professor Jacopo Torriti will present his research on the timing of electricity demand, peaks, people’s activities and demand-side flexibility.
