Demographic stats

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.

Breakdown of typical contributions to peak electricity demand across all sectors.

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.

Local Generation

Type Electrical Capacity (MWe) Heat Capacity (MWt)

Local electricity infrastructure

There are two Grid Supply Points (GSPs) that directly supply Bristol. These are located at Seabank and Iron Acton and shown on the map below along with the outline of the Bristol urban area.

The table below gives the number of substations at different voltage levels in both the Bristol City limits and the Bristol Urban Area.

Bristol City Bristol Urban Area
132kV substations 5 7
33kV Substations 24 35
11kV Substations 1,858 2,616
