RTE is required by law to publish a Ten-Year Network Development Plan so that public authorities can consult it and factor it into the operational application of the Multiannual Energy Programme.
In September 2019, RTE published a Ten-Year Network Development Plan, or “SDDR” in French, outlining planned changes to the transmission grid through 2035.
The CRE (Energy Regulatory Commission), in a statement dated 31 July 2020 on its review of the SDDR, said it was in agreement with the key principles of the plan. These principles focus on optimising costs associated with the adaptation of the grid to the energy transition and limiting its environmental impact.
The SDDR includes five industrial chapters based on the five recommendations in the Multiannual Energy Programme regarding the need to orchestrate the first major transformation of the grid since the 1980s:
|Initiate the first renewal since the grid was built and be in a position by 2030 to considerably step up of the effort (by about 30 %).|
|Adapt the grid to the new mix: ability to handle increased flows by boosting capacity on existing lines, building new lines and removing those that will less necessary.|
|Continue to develop and adapt the digital backbone of the grid while enhancing cybersecurity controls and having new technologies operate the existing grid as close as possible to its limits, while reducing the need for new infrastructure.|
|Over 15 years, double France’s interconnection capacity, to take full advantage of differences between consumption and generation in Europe and end up with a mix that is balanced and economically sustainable by 2035.|
|Build a grid to connect marine energy capacity.|
