Delivery tests

As written in Functioning Rules of Strategic Reserve, Elia or the SR supplier can plan a test activation to test the proper functioning of the contracted SGR/SDR-unit. A delivery test on the request of the supplier should be communicated to Elia according to the terms described in its SGR/SDR contract.

As soon as a delivery test on the request of the supplier is accepted by Elia, it will be announced in the following table:

List of already foreseen delivery tests requested by the supplier and approved by Elia

Date Hour interval Maximum injected power [MW]

A delivery test on the request of Elia shall not be announced in advance to the supplier. These tests will therefore only be communicated to the market via RSS Feed and on the page ‘Imbalance prices’ at the moment that the notification request is sent to the SGR/SDR supplier.

The table below shows the executed delivery tests during the current winter period:

Date At the request of Hour interval Maximum injected power [MW]
 11/12/2017 SGR Supplier 07h30-17h00  >300
 12/12/2017 Elia 05h00-13h45 200-300
 16/01/2018 SGR Supplier 07h30-17h00  >300
 23/01/2018 Elia 07h15-16h00 >300

In case of a test activation, there is no risk of “Structural Shortage of the Zone” by an economic or technical trigger.

The indicated hour interval is the period in which the SGR unit will inject power into the grid or the SDR unit will reduce its consumption. During this period, the imbalance prices will be administratively calculated as written in the paragraph 6.7.2 of the Functioning Rules.

The maximum injected power is the power range at the quarter-hour(s) of maximum injection. For example, if the foreseen maximum injection is 226 MW, the published maximum injected power is equal to 200-300 MW. Elia will monitor the system and holds the right to cancel or stop the test at any time.

This page is regularly updated with the latest information; however there will always be a delay between operational decisions and the publication. For real-time monitoring of a test activation (at the request of the supplier or at the request of Elia), please refer to the pages RSS Feed, Status Activation and Imbalance prices.
