Non Half Hourly (NHH) Estimation During COVID-19

This guidance is primarily aimed at addressing estimation for NHH non-domestic customers whose load may have reduced.  The estimation of NHH domestic customers may also need to be adjusted, but due to the number of customers this may not be practical to do at this stage.  Suppliers should discuss with their Supplier Agents whether changes to NHH domestic customers should occur and can be managed at this time.  We would encourage Suppliers to obtain readings from domestic customers (for example through customer own reads) at this time to provide further accuracy to Settlement – which is preferable to revising EACs manually.
