This dataset\ncontains the total losses across the network.\u00a0
Distributing electricity across a large area inevitably leads to electrical 'losses'. In simple terms, the energy entering our network is higher than the energy received by our customers and this is what we call a 'loss'. Losses can occur in a number of ways, please refer to our losses site\u00a0for more information.
\nNetwork losses in this dataset are\ncalculated as the difference between units of electricity entering the network and units exiting the network. Due to delays in the data required to calculate the losses, final losses are not determined until 14 months after the date, referred to in this dataset as 'RF', albeit these can still change for up to 6 years due to corrections to IDNO and half-hourly customers' data.
Delayed data includes the consumption of domestic customers and generation of small generators due to infrequent meter readings. Initial estimates are made (for example, estimated domestic bills), and it takes 5 reconciliations over a 14 month period to approach an accurate figure for units exiting the network. Our reporting is often required at the start of this reconciliation cycle, so the most up to date data available at that time is used but this will become outdated as further reconciliations come in.
In addition to the reconciliations, the values used for our reporting are displayed in columns labelled 'Regulatory Reporting'. In some areas the reported values are not an exact match for any previous iteration of the data. This is due to metering errors of half hourly metered customers which are later corrected by the customer.
\nConsumption data is sourced from Elexon, the company that manage the Balancing and Settlement Code. The main purpose of this data is to provide the data for billing DUoS, hence it is not necessarily complete for unbilled consumption or generation.\n\n
\n\nData is provided \"as is\".
\nData has been checked against regulatory submissions for consistency
\n\nThe Open Data Team and Net Zero & Network Development Team worked together to ensure data accuracy and consistency.
