AO10 Grid Connections is the French PPE3 offshore wind grid-connection package associated with the State’s tenth offshore wind tender (AO10), developed and to be owned by the national transmission system operator Réseau de Transport d’Électricité (RTE). Under PPE3 and the draft multiannual energy...

On 24 March 2025, the French Directorate General for Energy and Climate (DGEC) launched a public consultation on proposals for the AO10 offshore wind call for tenders, which will award 8.4–9.2 GW of new capacity by the end of 2026. The consultation, relevant to the AO10 Grid Connections as it addresses whether 2 GW plots should be developed as single 2 GW or paired 1 GW projects with shared HVDC connections at 320 kV or 525 kV, seeks stakeholder input on plot configuration, shared connection arrangements, locations, commissioning dates, and tender rules, and is open until 4 April 2025.
By its Network Investment Outlook webinar on 11 February 2025, RTE reported that it had launched two multi‑project calls for tenders to secure the supply of offshore substations and HVDC converter stations for AO9 and AO10 offshore wind grid connections and associated internal network reinforcements. Under this procurement, which covers AO10’s planned 2 GW and 1.2 GW HVDC onshore/offshore converter substation series, each of the two major substation contracts will be awarded to a single supplier to capture standardisation benefits across projects.

On 25 October 2024, French transmission system operator RTE issued a preliminary request for information to consult the market ahead of a long‑term tender for underground and subsea 320 kV and 525 kV HVDC cable links for offshore wind farms in France due to be commissioned from 2034, including grid connections that will serve AO10 offshore wind capacity. The consultation covers both onshore and offshore cables and is intended to inform an EPCIC and IMR contracting strategy for these HVDC export connections, without affecting bidders’ eligibility for the later AO10‑related cable tenders.
