Supplier Hub Operations

Supplier Volume Allocation (SVA) is the set of processes used to estimate the quantity of energy used or exported by a Supplier’s customers in a given half hour (or “Settlement Period”).

These processes are defined in the BSC Procedures for Supplier agents (Meter Operator, Data Collector and Data Aggregator) and Supplier Meter Registration Agents (SMRA).

Elexon has produced a number of guidance notes to supplement these procedures and provide best-practice advice. These guidance notes relate to areas such as performance improvement and exception management.
