Total non-domestic electricity consumption (Gigawatt hours) (3792) Metric type
- Help text
- This is the total consumption of all non-domestic (commercial and industrial) electricity in Gigawatt hours (GWh) for the area.
The data is annualised and is not weather corrected. The consumption is based on Non-Half Hourly (NHH) meters (these are the standard domestic and Economy 7 type tariffs) and is for a time period normally of 31st January to 30th January. Half Hourly (HH) meter figures published at Middle Layer Super Output Area (MSOA) level have been excluded.
The dataset also includes an aggregated total of consumption for unallocated, that is, consumption that was not able to be matched to an area due to incomplete or a lack of postcode information (this usually accounts for less than 1 per cent of consumption).
To complete the data allocation process, the NSPL is used to allocate MPAN postcodes and the associated consumption to statistical local authority level. This implies that any address containing a PO Box number will be assigned to the local authority area of the Post Office sorting depot. This is particularly important for interpretation of the data at levels below that of local authority level, as consumption may be allocated to a different area than where it is actually taking place.
Domestic meters are reallocated to the industrial and commercial sector if annual consumption is greater than 100,000 kWh. Also re-allocated to the industrial and commercial sector are those consuming over 50,000 kWh with address information indicating non-domestic consumption.
The number of meters does not exactly equal the number of properties. The reasons for this are as follows:
1. An apartment building may have a meter for the building complex (used to power building-wide appliances) in addition to each individual apartment having its own meter.
2. Some households may have a 3-rate meter system. A household with such a system will have one meter which measures all consumption at a peak rate and another meter which measures two other rates of off-peak consumption. This is the case for many households in Scotland, but it is extremely rare to find a similar case in England or Wales.
3. Some meters power street lighting or traffic lights rather than a property (many of these are unallocated).
Domestic meters are reallocated to the industrial and commercial sector if annual consumption is greater than 100,000 kWh. Also re-allocated to the industrial and commercial sector are those consuming over 50,000 kWh with address information indicating non-domestic consumption.
This data does not include Central Volume Allocation (CVA) users; large industrial consumers who receive their electricity through high voltage lines of the transmission system and hence have different arrangements with their electricity suppliers than Half Hourly (HH) and Non-Half Hourly (NHH) metered customers. Consumption by CVA users generally account for 1.5 to 2 per cent of electricity sales. It also exlcludes electricity used by companies that generate their own electricity and consume it without passing over the public distribution network. Some of this “auto-generation” is from government schemes.
