The Grand Duchy of Luxembourg is supplied by two high-voltage double lines from Germany via the Trier and Bauler substations. There is also an interconnection with Belgium.
The electricity is sent to the Flebour, Roost, Heisdorf, Bertrange, Blooren and Schifflange transformer stations, where the voltage is lowered from 220 to 65 kV, before being distributed to more than forty 65/20 kV substations throughout the country.
These high and medium voltage networks are controlled and managed by a control centre called Electricity Dispatching.
To manage such a complex system, the Dispatching Centre is equipped with a graphic display (PSI SCADA system) that shows the electrical status of the network (voltage, power, position of circuit breakers and switches) in real time.
The Dispatching Centre's state-of-the-art IT system enables remote intervention, thanks to an interactive network diagram. This means that certain operations can be carried out directly from the control room, without having to send a team to the site. This greatly reduces intervention and repair times in the event of a breakdown.
In the event of an emergency situation or a situation involving multiple incidents which has not been taken into account in the preparation of the operating programme and which cannot be resolved without affecting customers, the system operator will assess the situation and, taking into account articles 12 and 13 of the amended law of 1 August 2007, may take all the necessary measures to ensure the safety, reliability and efficiency of the system.
In particular, the recovery plan sets out the operational procedures to be applied at the level of the CREOS system operator and of the users of the CREOS transmission and distribution networks in the event that all or part of the CREOS electricity system has to be restored.
Article 9 of the amended law of 1 August 2007 on the organisation of the electricity market requires the transmission system operator, in consultation with the Government Commissioner for Energy and the regulator, to draw up a security code and a recovery code to be notified to the Minister.
Following the entry into force of the Network Code on the state of emergency and recovery of the electricity network (Commission Regulation 2017/2196) of 24 November 2017, it was necessary to adapt the Recovery Code to the provisions of Chapter III of this Network Code. The name of the Recovery Code has therefore been changed to "Recovery Plan".
It should also be noted that the name of the Safeguard Code has been changed to "Power System Defence Plan".
Informing major consumers, suppliers and producers is an important element in the successful implementation of the Recovery Plan. For this reason, Creos strongly recommends that all customers connected to the 220 kV and 65 kV networks, as well as suppliers operating in Luxembourg and large producers, send their contact details to our dispatching department using the form below.
In response to the current energy crisis, the Government has initiated an update of the Defence Plan. This version differs in particular in that it takes a broader view of the customers that could potentially be disconnected and in that the hierarchy of possible manual load shedding has been modified. The provisions for automatic load shedding in the event of low load have not changed.
The list of high voltage customers N3.1 and N3.2 is confidential. The customers concerned will be informed individually of their position in the hierarchy of the Defence Plan.
The various provisions of the Defence Plan have been adapted to take account of these changes. There is currently no provision for load shedding via smart meters, and load shedding via private charging points for electric vehicles has also been removed from this new version.
