CRM Pre-delivery monitoring
During pre-delivery monitoring, Elia verifies the progress of the contracted CMU to ensure that it will effectively be able to provide its capacity by the beginning of the Delivery Period
After the capacity contract signature, a new timeframe called the pre-delivery period begins. The period prior to the delivery period refers to the timeframe between the end of the auction and the beginning of the delivery period.
In this period, through the CRM, Elia gathers information on the ability of the contracted capacity to deliver the service for which it is contracted, i.e. having the capacity to be effectively available during scarcity moments (seeRemuneration, payback and availability page). To reach this objective, several obligations are in place during the pre-delivery period such as submitting quarterly and/or permit reports and eventually demonstrating capacity during moments of control.
During the pre-delivery period and before its end, Virtual and Additional capacities will also need to evolve to the status of Existing capacity.
If not on track, there is a risk to incur several penalties; the contract can in some extreme circumstances even be stopped, and the unreleased volume of the CMU may be added as an extra need to the inputs for the calibration of the Y-1 auction parameters.
Pre-delivery obligations
Moments of control
A moment of control, tcontrol, is an instance where ELIA will verify whether the CMUs with contracted capacities will be able to meet their obligations during the Delivery Period.
The amount and timing of the moment of control vary depending on the Auction in which the CMU was contracted:
- CMUs contracted in the Y-4 & Y-2 Auctions are subject to two moments of control
- Y-4: tcontrol,1 takes place on August 31 Y-2 and tcontrol,2 takes place on October 31 Y
- Y-2: tcontrol,1 takes place on August 31 Y-1 and tcontrol,2 takes place on October 31 Y
- CMUs contracted in the Y-1 Auction are subject to a single moment of control
- Y-1: tcontrol,2 takes place on October 31 Y

What is checked at moments of control
At moments of control Elia looks at the amount of Capacity a CMU can demonstrate and compares it to the pre-delivery obligation volume.
Timing | Existing & Additional CMU | Virtual CMU |
tcontrol,1 | Total Contracted Capacity | 75% of Total Contracted Capacity |
tcontrol,2 | Total Contracted Capacity | Total Contracted Capacity |
The demonstration to cope with the pre-delivery obligation depends on the CMU’s status. Note that Virtual and Additional CMUs MUST evolve to an Existing status before tcontrol,2. More information is provided below about this process.
Timing | Existing CMU | Additional CMU | Virtual CMU |
tcontrol,1 |
Based on:
|
Based on the information in the last Quarterly Report | Capacity transferred to corresponding Existing CMU |
tcontrol,2 |
Based on:
|
CMU is expected to be existing at this moment in time, so it’s based on:
|
Capacity transferred to corresponding Existing CMU |
If the CMU cannot demonstrate the required capacity, Elia has to apply a penalty(ies) which may be, as a last resort, covered by the Financial Security if this (these) remains unpaid. The value of this penalty is proportional to the Missing Volume of that capacity, which is calculated as the positive difference between the Pre-delivery Obligation capacity and the amount of capacity that was demonstrated by the Capacity Provider.
Report submission
During the Pre-delivery Period, based on the CMU status, the Capacity Providers are bound to submit different kind of reports to enable Elia conducting its verifications. The kind of report depends on the status of these capacities:
All Existing CMUs provide a permit report to ELIA
- This report is provided during the two weeks preceding tcontrol,1 through the CRM IT interface
- The permit report contains information regarding the permitting status
- CMUs contracted at Y-4 & Y-2 Auctions provide it once, at the latest by the moment of control tcontrol,1
Both Additional and Virtual CMUs provide quarterly reports to ELIA
- Contains information regarding the project execution plan, as well as potential delays
- Each quarterly report needs to be submitted through the CRM IT Interface during the following periods:
- From January 30 to February 14;
- From April 30 to May 14;
- From July 30 to August 14;
- From October 30 to November 14.

You can access the pre-delivery monitoring module on the CRM IT interface.
How to become an Existing capacity?
How to Evolve from Additional CMU to Existing CMU
To become an Existing Capacity Market Unit (CMU) if you are currently contracted as Additional, you must finalize the Prequalification Process initially completed. You need to update your Prequalification File for the Additional CMU in the CRM IT interface. Only new or additional delivery points require extra information.
You need to submit your amended Prequalification File either by the general submission deadline for prequalification, i.e. 15/06, or at the latest 20 working days before the key control moment (tcontrol,2). Elia will review and process the submission within specific deadlines.
In parallel, Elia will calculate the Nominal Reference Power (NRP) of your Delivery Points about to become Existing based on historical or commissioning data, and, if required, coordinate testing with you and the relevant grid operator. More information on Prequalification page.
ELIA will communicate the results of the transition process to you in line with the applicable deadlines. If the transition is not completed in time, a “Missing Volume” will be considered and may lead to pre-delivery penalties.
How to Evolve from Virtual CMU to Existing CMU
To evolve from Virtual Capacity to Existing Capacity and transfer the corresponding Contracted Capacity, the Capacity Provider has to prequalify these Existing CMUs during the Pre-delivery Period. Prequalification page
You need to submit your amended Prequalification File either by the general submission deadline for prequalification, i.e. 15/06, or at the latest 20 working days before the key control moment (tcontrol,2). Elia will review and process the submission within specific deadlines.
During the prequalification of the now Existing CMU(s), the link between the new Existing CMU(s) and the Virtual CMU must be specified in the file. This identification allows ELIA to accept the previously submitted financial security for the Virtual CMU, and to apply the relevant derating factors for the delivery period and auction in which the Virtual CMU was contracted.
Once the Existing CMU(s) are prequalified, ELIA will automatically transfer the Contracted Capacity from the Virtual CMU to the Existing CMU(s). After a successful transfer, the financial security is partially released, and if all contracted capacity is transferred, the Virtual CMU is archived.
