Smart meter LV feeder half hourly usage data is collected directly from smart meters in homes and businesses and anonymised through aggregation to no less than 5 properties through SSEN’s smart meter adapter. There is a postcode and LV Feeder Dataset ID lookup to provide the aggregated half hourly consumption data in Wh (combined primary and secondary active import Wh), from the relevant secondary transformer and low voltage feeder IDs with a total count of smart meters. Please note that the aggregated half-hourly data provided via our Open Data Portal is sourced from smart meters. Smart meters, their performance, and the data stored within them are the responsibility of the energy suppliers who install them at customers’ premises. There are some known and potential unknown issues within the data, and while we make reasonable efforts to ensure the accuracy of the smart meter data retrieved, we do not accept responsibility or liability for its accuracy, completeness, or any loss arising from reliance on this dataset.
