Data requirements

Data requirements

The EDI-Net system provides an automated continuous analysis of metered consumption data. In order to use EDI-Net there are certain requirements in terms of the data quality and quantity.

Resolution

To receive the full EDI-Net service users are expected to provide data at a fairly high resolution, ideally hourly or better. As part of the data analysis the service will aggregate data to half-hourly resolution, higher resolution data will not be reflected in the analysis. The service also interpolates lower-resolution data to half-hourly consumption. Lower limits on data resolution are uncertain, hourly readings are fine, using lower resolution data is possible but will impact on the reliability of the results.

Historic data

Typically we expect to import around two years of historical data to allow the system to analyse the historic patterns of consumption. For a reliable analysis a minimum of 12 months is required. Where less data are available the system can still be used but again, the results may be unreliable. The good news is that data are continually being generated and eventually a 12-month baseline will accrue.

Import frequency

For ongoing data imports we expect most users would import data several times per day and keep the system up-to-date to the nearest few hours. We recommend a minimum of one upload per day, to be scheduled overnight so that every morning the data for the previous day are available. Note that the import frequency strongly affects the efficacy of dynamic feedback. The analysis will only change when new data are uploaded. In periods between uploads, the system will remain static.
