How to use the delivery monitoring page

This article explains the Delivery Monitoring page, the various volume types and what each one is for.

What is this about?

When you source EACs (We use EAC - Energy Attribute Certificate - to describe all types of certificates including GOs, iRECs, REGOs, HKN, etc.), you're managing two parallel realities at once: what you've contracted to receive, and what has actually landed in your registry accounts. Keeping these in sync is a core operational task and when they diverge, you need to know quickly.

The Delivery Monitoring page, brings both sides together. It surfaces the connection between your contracted supply volumes (also called sourcing commitments or procurement contracts) and the actual certificate deliveries that have been reconciled against them — so you can identify gaps, confirm what's been settled, and act on anything that's still outstanding.

This page is particularly relevant for back-office teams running regular reconciliation cycles, and for portfolio managers who need confidence that their supply position reflects what's actually in inventory.

The three tabs

The page is organised into three tabs, each providing a different perspective on your inbound supply. You can switch between them using the tabs displayed above the data grid.

Expected volumes

Also referred to as: contracted volumes, sourcing commitments, open obligations

This tab starts from your contracted side — the volumes you are expecting to receive, whether from metered supply (asset offtake or PPAs) or fixed-volume buy deals. Think of these as your purchase orders.

For each contracted line item, you can see:

How much has been received — i.e. reconciled against an inbound registry transaction (also called a matched or settled volume)
How much is still outstanding — not yet matched to any inbound delivery (also called the undelivered or shortfall volume)

This is the right tab when you want to identify gaps: contracts or deal tranches where the expected certificates have not yet arrived in your accounts. If the outstanding volume is non-zero for a period that has already passed, that's a signal to follow up with the counterparty, the registry, or your asset operator.

Delivered volumes

Also referred to as: inbound transactions, received certificates, registry inflows

This tab starts from the opposite direction — it shows the certificates you have physically received through inbound registry transactions (issuances or transfers into your accounts). Think of these as your incoming shipments.

For each inbound delivery, you can see:

Delivered volume — the total volume of the registry transaction
Reconciled volume — how much of that delivery has been processed through the reconciliation workflow (matched to a contract, or explicitly accepted without one)
Unreconciled volume — the portion still awaiting reconciliation

This tab is most useful for tracking which inbound transactions still need to be actioned. Any row with a non-zero unreconciled volume is a transaction you haven't yet processed on the Registry Transactions page. Once reconciled, the volume moves from unreconciled to reconciled.

Reconciled volumes

Also referred to as: matched pairs, settled deliveries, reconciliation records

This tab shows the confirmed matches — the specific links established between a contracted volume and a delivered transaction through the reconciliation process.

Where the previous two tabs each show volumes from one side, this tab shows the joint record: what was contracted, what was received, and exactly how much of one was matched against the other. It combines the attributes from both the contract side and the delivered certificate side in a single row.

This is most useful for audit purposes, for investigating specific reconciliations, or for verifying that a complex delivery

has been mapped correctly across multiple deals or tranches.

How the three tabs relate to each other

The three tabs are different lenses on the same underlying data:

Expected volumes is contract-centric: "For each thing I expected to receive, how much has arrived?"
Delivered volumes is transaction-centric: "For each thing that arrived, what contract does it belong to?"
Reconciled volumes is the join: it shows every confirmed match between a contract and a delivery

Reconciliation is what connects the first two. Until a transaction has been reconciled, it appears in Delivered volumes as unreconciled — but it does not yet reduce the outstanding balance shown in Expected volumes. Once reconciled, both tabs update to reflect the matched volumes, and the match itself becomes visible in Reconciled volumes.

Tips & things to know

Reconciliation is a prerequisite for accurate delivery tracking. The Expected and Delivered volumes tabs only reflect actual delivery accurately once transactions have been reconciled. If you see unexpectedly large undelivered volumes on the Expected tab, check whether the corresponding inbound transactions have been processed on the Registry Transactions page.
The Reconciled volumes tab is your audit trail. If you need to demonstrate exactly which certificates were delivered against a specific deal or tranche, this tab gives you the most granular, line-by-line view.
Outstanding volumes on past periods are your action items. If a generation period has passed and undelivered volume in the Expected tab is still non-zero, it means certificates are either not yet in your accounts, not yet uploaded to the platform, or not yet reconciled. Each case requires a different follow-up action.
