Mandatory Half Hourly Settlement for 05-08 Supplies

Under Ofgem’s Balancing and Settlement Code (BSC), it is a requirement that larger non-domestic supplies, with an old meter profile class 05 to 08, are settled on the Half-Hourly (HH) market with Automated Meter Reading (AMR) meters recording the data. Where an AMR meter is installed on profile class 05 to 08, it must be set up to provide HH readings to suppliers, improving the accuracy of bills and providing actual data from which businesses will be better able to manage energy use.

Moving from NHH settlement to HH settlement ensures that energy usage will no longer be estimated, meters are read remotely and billed accordingly. The measurement class of the supply changed depending on the meter type (i.e Current Transformer (CT) meter or Whole Current (WC)) and the Distribution Network Operator (DNO) assigned the supply a capacity per MPAN. The default capacity was set at 71kVA until the relevant DNO has assigned a more accurate capacity for the supply.

All supplies must now have a Meter Operator (MOP) Agreement and Data Aggregator/Data Collector (DA/DC) Contract in place.

For supplies that have migrated to HH status can challenge the capacity assigned to the supply if it is under or oversized.
