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.
