Energy data flows explained
Behind every accurate energy bill sits a constant exchange of standardised messages between suppliers, networks and meter operators. These are the industry data flows. When they run cleanly, settlement and billing just work. When they fail, errors and disputes follow. Here is what they are and why they matter more than ever.
What energy data flows are
In the GB electricity market, participants do not email each other spreadsheets. They exchange standardised electronic messages, known as data flows, defined in the industry Data Transfer Catalogue and sent over the Data Transfer Network. Each flow carries a specific piece of information, such as a meter reading, a change of supplier, a new registration or an update to a supply record, in a format every party can read the same way.

These flows are the plumbing of the market. A meter reading flow moves a reading from the meter operator to the supplier and settlement. A change of supplier flow moves a supply from one supplier to another. Thousands of these messages pass every day, and the accuracy of every bill and settlement depends on them being sent, received and reconciled correctly.
Why data flows matter more now
Two things are raising the stakes. First, volume. As the market moves to half hourly settlement under MHHS, the number and richness of the flows a supplier must handle rises sharply, because settlement now runs on forty eight points a day rather than a periodic estimate. Second, expectation. Customers and the regulator expect faster switching and accurate billing, and both depend entirely on flows being processed cleanly and on time.
When a flow is missing, late or malformed, the effect is not abstract. It shows up as an estimated bill, a stalled switch, a settlement error or a customer complaint. The businesses that cope best are the ones that automate the handling of flows and, crucially, the exceptions when a flow does not arrive as expected.
Where flows go wrong
Missing readings
A reading flow that never arrives forces an estimate, which drives inaccurate bills and later disputes.
Stuck switches
A change of supplier flow that fails can leave a switch in limbo, frustrating the customer and the supplier.
Mismatched records
When supply records fall out of step between parties, settlement and billing quietly drift out of line.
Rising volume
Half hourly settlement multiplies the data. Manual handling that coped before cannot keep up.
Exceptions unmanaged
The real cost is in exceptions. Flows that do not arrive as expected need chasing and resolving fast.
Slow reconciliation
If flows are not reconciled promptly, errors compound and become far harder to unwind later.
Common questions
What is an energy data flow?
A standardised electronic message that moves a specific piece of information, such as a meter reading or a change of supplier, between market participants in a format every party reads the same way.
How do data flows relate to MHHS?
MHHS moves the market to half hourly settlement, which sharply increases the volume and richness of the flows suppliers must handle, making clean automated processing essential.
What happens when a flow fails?
It surfaces as an estimated bill, a stuck switch, a settlement error or a complaint. The fix is fast detection and resolution of the exception.
How does OptiFlow help?
We automate the sending, receiving and reconciliation of flows and, most importantly, the exceptions, so errors are caught and resolved before customers feel them.
