Metering Systems accurately record the flow of electricity to (an Import) or from (an Export) a site. Metering System data is used to calculate energy imbalance charges. These charges are applied to BSC Parties who use more or less energy than they have contracted to buy or generate.

Suppliers and generators, Licensed Distribution System Operators, the Transmission System Operator, Interconnector Administrators and Elexon also use Metering System data for other charging purposes, both within and outside the BSC arrangements.
Larger sites, in the Central Volume Allocation market, may have several Meters where it becomes necessary to aggregate the volumes of all the relevant Meters to find the total. Registrants of such Metering Systems create and submit Metering System Aggregation rules.
Half Hourly Metering Systems are subject to Technical Assurance of Metering (TAM) Performance Assurance Technique (PAT). TAM is designed to provide assurance that Metering Equipment complies with obligations outlined in the BSC Code and subsidiary documents.
Q & A webinar
On 30 June we hosted a virtual Metering training day. The day consisted of Central Volume Allocation (CVA), Supplier Volume Allocation (SVA), and Technical Assurance of Metering (TAM) training. You can watch the training videos below

Current and Voltage Transformers
Metering Systems can be comprised of measurement transformers such as Current Transformers and Voltage Transformers. The ratios for these transformers are communicated between Parties via Meter Technical Detail (MTD) data flows. These ratios are instrumental in allowing a meter to record the correct primary energy flow to or from a site.
Accurate measurement of transformer ratios is essential for the commissioning process, which is a series of site tests and checks on Metering Equipment. Licenced Distribution System Operators (LDSOs) and Meter Operator Agents (MOAs) will need the valid list of transformer ratios, which can be found via the page alone.
