### Overview
This dataset is derived from National Grid Energy Distribution (NGED) smart meter usage data, aggregated at LV feeder level. The data represents consumption per LV feeder, aggregated across a minimum of 5 smart meters, at half hourly resolution. The NGED usage data has been combined with LSOA data for England and Wales to provide the relevant Output Area for each reading.
The the set of raw NGED data files is available from their [Open Data Portal](https://connecteddata.nationalgrid.co.uk/dataset/aggregated-smart-meter-data-lv-feeder/datapackage.json).
### Methodology
The datasets have been generated using an pipeline to automatically collect new data as it is published. The data is processed, combined with the locational data described above, and output as parquet files for each calendar month.
### Coverage and update rate
NGED publishes batches of files (around 200 per calendar month), for a subset of it's network coverage area (around 3000 secondary substations). On average data is published around 1 month behind real time.
### Units
Aggregated usage is provided in **Wh**. All timestamps are **UTC**.
### Acknowledgements
The development of the data pipeline was inspired by work on the [Weave](https://weave.energy/) project.
