What to tell EBX before, during and after an unexpected fault, so cover can be coordinated while your team restores the asset.

## In short

For asset owners and operations and maintenance (O&M) teams, the priority during an ancillary-service commitment is to keep the agreed capacity available. If a fault occurs, prompt information allows EBX to coordinate cover while your team restores the asset.

EBX guarantees collateralisation for an unexpected single-unit failure up to the largest technical unit (LTU). Larger outages receive best-effort cover. The agreed collateralisation fee applies, with additional penalties for outages beyond the LTU as specified in your contract. That cover is explained in [Ancillary-service commitments and EBX’s outage cover](https://docs.ebx.energy/knowledge/collateralisation/outage-cover.md).

## Who this is for

**Asset owners and O&M teams** operating an asset that is committed to ancillary services through the EBX pool.

## Before a committed delivery period

Make sure the asset’s reported availability reflects its actual capability. Share planned maintenance, grid curtailment and known power or energy limits with EBX and your optimiser as early as possible so they can be considered before bidding.

If a commitment already exists, contact EBX promptly to coordinate how it can be fulfilled. Reporting a restriction does not cancel that commitment.

Your O&M team should understand which components can fail independently and which shared components could cause an outage beyond the LTU. Clarify the site’s technical-unit configuration and applicable cover with EBX before relying on an assumption such as "one inverter is covered."

## When a fault occurs

Report the change through the EBX Control Center or API.

The report includes:

-   The affected asset and component or unit.
-   When the restriction began.
-   The power and energy capability still available.
-   The known cause and expected recovery time, or an indication that these are still being assessed.

Please report the loss of availability even if no balancing energy is being activated at that moment. The reserve commitment remains in place.

EBX assesses the affected commitments, coordinates replacement capacity and handles the required TSO communication. Your team manages the technical repair and keeps EBX informed of changes.

## During recovery and follow-up

Report partial recovery accurately. An asset that has restarted may still be unable to sustain its full committed response. Confirm when its capability has been restored so EBX can take that into account.

For larger or recurring faults, investigate the cause and agree corrective measures with your O&M team. Keep a record of the outage, its impact and the action taken; this helps EBX respond to any TSO clarification request.

The aim is to restore reliable participation together. Collateralisation supports delivery when an unexpected fault occurs, while sound maintenance and timely communication reduce the risk of further outages, additional charges and prequalification concerns.
