Energy stats

Bristol has an annual electricity consumption of 1862 GWh (data from 2013) and a daily peak power demand of around 307 MW during winter months. The daily peak demand is calculated by applying the peak to annual consumption ratio of the UK to Bristol.

Bristol's annual gas consumption is 2738 GWh (data from 2013). There is insufficient data available to calculate the peak gas consumption. Because of the inherent storage capacity in the gas network there are fewer issues surrounding the peak.
