Problem Statement
There is not a consistent understanding around the Complex Site process which can lead to the Complex Site Supplementary Information Form (CSSIF) being populated or interpreted differently by different parties. This may lead to incorrect data being used for consumer billing and Settlement, which can result in BSC Trading Disputes.
Proposed solution summary
- As an electricity Consumer, I want my metering data to be accurate, to ensure my account is set up correctly and I receive accurate and timely invoices.
- As a Metering Equipment Manager, I want to have clarity on my obligations to provide data - specifically what data I need to send, who the recipients are and when I need to send it to ensure I provide accurate data to other Market Participants. As an Electricity Supplier and as an Electricity Distribution Network Operator (DNO), I want to receive accurate and complete Meter Technical Details (MTD) to enable me to take appropriate action following a change of metering equipment, a switch, a change of HHDC, a new connection a meter configuration or MEM.
- As a Half Hourly Data Collector, I want to receive accurate and complete Meter Technical Details to enable me to take appropriate action following a change of metering equipment, change of supplier, change of HHDC, new connections, meter configuration or MEM.
