General framework of the activity
At the core of the power system, RTE keeps the balance between power consumption and generation. Twenty-four hours a day and seven days a week, RTE plays a key role in directing the flow of electricity and maximising power system efficiency for our customers and the community. RTE conveys electricity throughout mainland France, from power generation facilities to industrial consumers who are connected to the transmission grid, and to the distribution grid which provide the link between RTE and end users. RTE operates France’s high and extra-high voltage transmission system, the biggest in Europe. We are the French transmission system operator, owner of the biggest transmission network in Europe.
RTE, the French transmission system operator
- Optimizing operation of the French power system, second by second.
- Seeing to the security of supply for our customers, with access to economical, reliable and clean electricity, now and tomorrow.
- Adapting the transmission system to facilitate the energy transition.
Specific skills in the MRE field
RTE is in charge of connecting new producers, such as offshore wind farms, to its network, and of developping the network and interconnections with neighboring countries that can use the maritime domain.
RTE is now also in charge of the delivery of the electrical substations for the connection of the French wind farms from the 3rd round of calls for tenders.
RTE is involved in all the phases of development of an EMR project:
- STUDIES AND DEVELOPMENT: Electrotechnical studies of the MRE offshore farms on the electricity transmission network and Technical engineering studies, R&D studies
- AUTHORIZATIONS: Consultation and environmental studies and authorizations to obtain
- CONSTRUCTION: Realization of the connections in close relation with the producers and Project management of the work of connection
- EXPLOITATION: Integration of MRE in the electrical system and operation and maintenance of offshore links
Projects in MRE
In addition to offshore wind farm connections, RTE is developing a number of projects using maritime space that rely on DC technology because of the significant underwater lengths. It includes projects for interconnection lines between Lower Normandy and the English coast, between Brittany and Ireland, and between Cotentin and Devon. A new interconnection project is also underway between northern Spain and New Aquitaine via the Bay of Biscay.
In total, RTE today has projects covering 1,500 km of underwater links projects (EMR + interconnections), which will be added to the historic “IFA 2000” link. For the development of offshore electrical networks, RTE is committed to respecting all the specificities of this environment.
RTE is a partner in the WEAMEC COMEOL research project.
Training in the MRE field
RTE is involved in the training module “Electrical Design and connection” in the WEAMEC “MRE technical advisor” Certificate.
