The Electric Network
AN ACCESSIBLE NETWOKR FOR THE TRANSMISSION OF ELECTRICITY
Ease of access and of connection with the electricity grid (réseau public de transport d’électricité (RTE)
) is a major requirement for wind farm projects. In Normandy, RTE already has the suitable infrastructure and is planning to reinforce its network in specific locations to adapt to the arrival of electricity generated from MRE sources.
The Cotentin-Maine extra high voltage line (EHV)
This 400 kV electric line was commissioned by RTE in May 2013.The EHV extends along 163 kilometres and was installed for a secured power supply in western France and to transmit the electricity produced from marine renewable energy sources. RTE invested 343 million euros in this upgrade.
The onshore electrical transmission stations are close and operational
RTE already owns suitable onshore electrical transmission stations across from, or near the offshore wind and tidal farm landfall points: in Ranville for the Courseulles-sur-Mer wind farm, in Sainneville-sur-Seine for the Fécamp operation and in Penly for the Dieppe-Le Tréport development.
Other onshore electrical transmission stations (Tollevast, Flamanville, Ifs) are already suited to the transmission of the energy flowing in from future offshore wind and tidal farms.
Additional capacity for the network
RTE has also planned to make its network more robust by building a number of additionnal subsea and subshore 225 kV twin connections to transmit the production from the future Normandy offshore wind farms.
