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.
Participants can report over 200 different activities. Here is a Sankey diagram to show how we categorise activities into larger and smaller subgroups.
The timing of he first lockdown was fortunate. The heating season had just ended and the weather was lovely. A winter lockdown brings new challenges for energy.
Explore the electricity use patterns of UK households. Which has the greater impact on demand: children or dogs? Power explorer.
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.
We created a new and simplified version of the household profile for participants. This one is suitable for mobile phones as well. We also added a feature to download your personal data as a csv file for your personal use. Here is a sample

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.
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.
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.
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?
For some the lockdown is easy to cope with, others face serious difficulties. Help us understand these unusual times and learn about potential long term effects at JoyMeter.uk
A short article about the opportunities arising for energy research under lockdown.
We continue to collect data during the lockdown. While national demand is at a record low, some households will see their bills go up.
Phil visited Hilary, June, Chad and many others of our collaborators at Stanford. It is great to see our tools in use in America.
Osney island excelled in our energy challenge. When asked to reduce demand between 5pm and 7pm, they achieved a record 18%!
METER launches in Germany. The University of Münster has developed their own electricity recorder and now uses the Meter App in German. We are excited to see how UK and German demand compare...

When we ask people to use less electricity in the evening, they cut down on hot meals and have a cup of tea instead.
We can get a 16% reduction in electricity use, just by asking.
Among the most enjoyable activities are sleeping, reading and socialising. These also use very little electricity.
Riverside and Oatlands Road have won the West Oxford challenge by reducing their demand the most between 5 and 7pm.
