Delivery tests
Elia notifies the market of strategic reserve delivery tests, as they may affect imbalance prices.
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:
Upcoming delivery tests
| Date | Hour interval | Maximum injected power [MW] |
Last update: 03/03/2017
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:
Executed delivery tests
| 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 |

Legend
-
Test interval
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 calculated using an administrative procedure, as set down in Article 6.7.2 of the Functioning Rules of Strategic Reserves.
-
Maximum injection
The power range at the quarter-hour(s) of maximum injection. For instance, if the planned maximum injection is 226 MW, the published maximum injected power will be 200-300 MW. Elia will monitor the system and reserves the right to cancel or stop the test at any time.
