This study provides an improved understanding of the end use components of peak demand electricity in the UK so that the potential for reducing peak demand through improved energy efficiency in the building stock can be assessed. It builds on earlier work and draws in additional data sources to provide an enhanced understanding of the end use components that make up peak electricity demand. To capture
the impact of change over the course of a year, the model considers the daily demand profile for the day in which peak demand occurred (in 2006), in each quarter. This showed that lighting, catering, consumer
electronics and, in the summer quarters cooling, are the building end uses where there is likely to be the most potential for demand reduction.
