Creos Luxembourg

Creos Luxembourg S.A. owns and manages electricity networks and natural gas pipelines in the Grand Duchy of Luxembourg.

 History 
Creos was formed as a result of a deal to unite:
Cegedel S.A. – the Grand-Ducal electricity company of Luxembourg. It was founded in 1928 and distributed 70% of the electricity in the country.
 Soteg S.A. – Luxembourg's primary gas supplier - and Saar Ferngas AG – a distribution company created in 1929 in Saarland. Archived 2007-08-07. 
2000s
On 23 January 2009 Cegedel S.A. and Saar Ferngas AG were moved to Soteg S.A. This made a new energy group named Enovos. It included the parent company Enovos International S.A. and the two main subsidiaries: Creos Luxembourg (formerly Cegedel S.A.) in charge of network activities, and Enovos Luxembourg S.A. in charge of production, sales and marketing. Enovos and Creos each have a subsidiary for the German market: Enovos Deutschland and Creos Deutschland.
2010s
In 2010,  Creos bought the natural gas networks from Luxgaz Distribution S.A. On 1 January 2011, the City of Luxembourg transferred its electricity and natural gas networks and its teams to Creos in exchange for owning units of property in Creos. The owned units of property increased from 5.71% to 24.57%,. 

In order to make a difference between the parent company and its subsidiaries – energy provider Enovos and grid operator Creos –, Enovos International is now called Encevo.  Private equity firm Ardian sold its stake up to 24.92 percent in Encevo to China Southern Power Grid International, the second grid operator in China and in the world.
2020s
Following a reorganization of the Encevo Group in Germany at the end of October 2021, Creos Luxembourg sold its stake in Creos Deutschland Holding GmbH  . On 1 July 2023, Laurence Zenner, previously head of CFL Cargo, became the new CEO of Creos Luxembourg.

Creos also has a shareholding in the following companies: 

 Luxmetering, an Economic Interest Group which pilots the smart metering network;
 Balansys, a joint-venture between Creos and Fluxys Belgium which aims to faciltate the integration of the Belgian and Luxembourg natural H gas market sectors into a single zone;
 Ampacimon, the world leader in electricity grid monitoring;
 TSCNet, a European company which provides coordination and support services to 16 transmission system operators (TSOs) to ensure the efficient and secure operation of electricity grids in Europe;
 JAO, a trading platform that hosts Europe’s leading cross-border trading system, e-CAT, and provides a full range of services from auctions for long- and short-term capacity rights to back-up auctions for day-ahead coupling.

 Business sector 
Creos Luxembourg S.A. plans, constructs and maintains the electricity and natural gas transmission and distribution networks in the Grand Duchy of Luxembourg.

In Luxembourg, following the liberalisation of the energy markets, an independent organisation – the Luxembourg Institute of Regulation – organises and supervises access to the networks. The tariffs are subject to its approval. The energy suppliers are guaranteed transparent access to Creos's networks.

 Infrastructure 

 Electricity network 
The majority of the electricity in Luxembourg comes from Germany via two double high-voltage 220,000 volt (220 kV) lines connected to the German network. Interconnection with Belgium has become operational with a phase shifting transformer at the Schifflange Centre in October 2017. Around 15% of the energy is produced locally (biogas, cogeneration, wind turbines, hydroelectricity and photovoltaics). 
Voltage
The electricity is send to the six stations (Flebour, Roost, Itzig/Blooren, Heisdorf, Bertange and Schifflange) where the voltage is reduced from 220 to 65 kV. It is given to industries and large municipal distribution networks. The voltage is then reduced from 65 kV to 20 kV in more than 60 transformer stations in the whole country. The electric energy obtained is distributed to SMEs, towns and villages where the transformers reduce the current voltage to 0.4 kV before distributing it to the final consumer. A control centre, known as Electricity Dispatching, controls and manages these high and medium-voltage networks.
Length
The total length of the Luxembourg electricity network managed by Creos is 12,595.9 kilometres, including 982.4 kilometres of high-voltage lines, 3,561.7 kilometres of medium-tension lines and 8,051.8 kilometres of low tension lines.

 Natural gas network 
Thanks to its connections with Germany, Belgium and France, Luxembourg is linked to the interconnected gas networks throughout Europe. Monitored by Dispatching Gas, the high and medium-pressure pipelines distribute the gas to 60 communes that are connected to the national gas network. Pressure-reducing stations that supply the local networks then reduce the gas pressure. Creos distributes natural gas in 45 communes,.

Since 1 October 2015, Creos and Fluxys Belgium, in collaboration with their respective regulators ILR and CREG, have united the national markets of Luxembourg and Belgium into one Belux market. This integration, the first between two European Union member states, reflects the will of the European Union to create an European gas market without borders,,,. Balansys, the joint venture between Creos and its Belgian counterpart Fluxys, is the balancing operator in the Belux zone from 1 June 2020. It is responsible for ensuring that the gas market is well supplied, without one of the two suppliers having to pay an entry fee for its gas on the other's market.

 Sites 
The Roost Centre covers the central and northern regions. It covers the high, medium and low-voltage electricity services and the medium and low-pressure natural gas services, the central store and the mechanical and electrical workshops,.

The Schifflange Centre covers the southern part of the country.

The Luxembourg City Centre, together with the company’s headquarters, is located in Merl.

The Contern Centre manages and adjusts the meters, in particular smart meters.

Dispatching for electricity and natural gas together with the monitoring rooms for remote network control and management are installed in Bettembourg.

 Projects 
European Energy Efficiency Directive
In accordance with the law of 7 August 2012 that puts the European Energy Efficiency Directive into Luxembourg law, all the gas and electricity meters across the country have been replaced in the country, regardless of the network operator. Creos has made 300,000 smart meters that record information about energy in Luxembourg. The electricity and gas meters — known as Smarty — contribute to the development of truly intelligent networks, or smart grids.,,,,.
Electric mobility
Creos contributed to the national e-mobility objective by installing the public charging stations known as Chargy throughout the country. This network was complemented by the SuperChargy network of ultra-fast direct current (DC) charging stations.[33] In 2025, the Minister of the Economy, SMEs, Energy and Tourism, Lex Delles (DP), signed the decree officially granting a seven-year concession for the operation of both the Chargy and SuperChargy networks to a private consortium, charge@lux. 

Energy Management
Creos is also preparing the Third Industrial Revolution of the country. This convergence of IT, renewable energy and means of transport will have an impact on how the power grids are managed. To anticipates this évolution, Creos is involved involved in several large-scale national projects.  

The Leneda platform (Luxembourg Energy Data Platform), launched in 2025, centralises data on electricity and gas consumption and production, making them accessible to the various market players and simplifying communication between them.  

KOPR, developed by DataThings, — a spin-off of the University of Luxembourg — is a digital twin of the Creos networks. It enables real-time analysis of network use and load, thereby optimising operational efficiency and resilience. 

The  FlexBeAn project, carried out jointly with the Luxembourg Institute of Science and Technology (LIST) and the Interdisciplinary Centre for Security, Reliability and Trust (SnT) of the University of Luxembourg, focuses on studying energy flexibility and user behaviour in response to new energy uses.

In parallel, Creos took a decisive step into the hydrogen era by creating the subsidiary Creos Luxembourg Hydrogen S.A.in 2024. This wholly owned company focuses on planning hydrogen pipelines in Luxembourg and internationally, in order to meet new European and national regulatory requirements and to support, among other initiatives, the HY4Linkproject. The HY4Link project, in which Creos Luxembourg participates, aims to establish a cross-border hydrogen transport network within the “Greater Region” (Belgium, Luxembourg, France, Germany), connecting industries to hydrogen import hubs (Antwerp, Zeebrugge, Rotterdam, Dunkirk) and integrating into the European hydrogen backbone.
