Solar Streets Electricity Demand

The following graph shows the electricity demand in half hour intervals, on two feeders from two sub stations. The first on Bloomfield Avenue, serving Maple Grove and a little bit of Bloomfield Avenue and the second on Elm Place serving the South side of Bloomfield Avenue, part of Wells Road and part of Bloomfield Road.

The second feeder into the Elm Place substation includes several commercial premises, hence why the electricity demand is significantly higher.

The second graph shows the total cost of electricity supplied on both feeders assuming either all households are paying an average standard electricity tariff or if they are all paying a ‘Time of Use’ tariff that charges the householder a different amount depending on the time of day, with a higher tariff during peak times and lower tariff at other times.

The third graph illustrates the variation in how carbon intensive electricity supplied during the day is, based on average data over a period of May to November 2019. The regional carbon intensity is significantly lower than nationally because of the relatively high level of renewable energy, particularly solar PV that there is in the South West, as well as nuclear power, and the relatively low level of fossil fuel generating plant.

On average in the South West, shifting electricity use from the evening to the afternoon can reduce carbon emissions by between 40-50% depending on the time of year.

The map below provides more detail of which properties the two feeders being monitored serve. The pink blobs indicate the properties served by the Bloomfield Avenue substation feeder and the green blobs indicate the properties served by the Elm Place substation feeder. The other colours are feeders we are not focussing on for this project.
