Does London UHI affect small supermarket electricity consumption?

Does London UHI affect small supermarket electricity consumption?

The Centre's Research Associate Ramon Granell presented the findings of a study into the effect of the London urban heat island (UHI) on the electricity consumption of small supermarkets at the Smart Grids Symposium in Glasgow on 13-14 September.

The study shows that the UHI effect can be observed in the power consumption of the supermarkets, with stores closer to the centre of London having a statistically significant higher energy consumption than those further from it. They study also found that consumption differences between the stores are higher during summer, suggesting that the stores' cooling systems may be responsible.

Granell's poster, 'Does the London urban heat island affect electricity consumption of small supermarkets', describes the year-long study of the relationship between electricity consumption by floor area of 40 supermarkets and their distance from London city Centre. Hourly electricity demand data was used to quantify the UHI effect on the supermarkets' consumption between July 2014 and June 2015.

The study was part of the WICKED (Working with Infrastructure, Creation of Knowledge and Energy strategy Development) project and was funded by EPSRC. The poster is co-authored by Colin Axon of the Institute of Energy Futures at Brunel University, Dr Kathryn B. Janda of the University of Oxford's Environmental Change Institute, and the Centre's Associate Professor and Associate Director for Innovation, David Wallom.

The HubNet Smart Grids Symposium 2016 took place at the Technology and Innovation Centre, University of Strathclyde, on Tuesday 13 and Wednesday 14 September. The Symposium, organised by HubNet, is an annual event that showcases outcomes from the UK Smart Grid research community to a broad audience of stakeholders. HubNet is a consortium of researchers from various UK universities tasked with coordinating research in energy networks in the UK.
