Learning to predict peak demand

Graphical abstract with illustrations of the research methods

Clustering load profiles is tricky. Even 'similar' high-resolution use patterns have little overlap, if they are slightly shifted in time. This paper applies a novel clustering approach for cumulative load profiles. Random forests walks identify explanatory variables for high peak time demand using our activity data.

Energy and Gender bargraph for housework

The gender divide in energy

Many energy models assume that women are responsible for more energy use than men. They do more housework after all. Our data challenges this assumption. While women do indeed report a higher number of household chores, their electricity demand appears to be lower. Find out what they do differently in this open access publication.

Lockdown rhythm

Changing rhythm

This is how lockdown affects the electricity grid. What used to be a regular weekly pattern (high demand during weekdays, low at weekends) has broken down. Variability is a challenge for system operators and forecasting demand is just as important as forecasting renewable generation.

Frequency and enjoyment change

Gardening and recreation increase enjoyment

Since the lockdown started we see more reporting of screentime, gardening and hot drinks. Washing/showers, work and (surprisingly) reading are down. Perhaps we should read more, given that it appears even more enjoyable, especially compared to screentime.

Lockdown rhythm

Response to COVID-19 lockdown

The activity patters we observe have changed dramatically. On average the day starts an hour later, more activities are reported in the morning and significantly fewer during the peak demand period in the early evening. This may have profound impacts on the timing energy use.

Lockdown demand

Reduction in demand

UK electricity demand has fallen. In a historic context this reduction is roughly equivalent to the last 6 years worth of energy savings. Thanks to sunny and windy weather, the emissions of our energy use are among the lowest we have ever seen. How much of this reduction can be sustained into the future?
