French TSO Prepares for Major HVDC Tender to Support Offshore Wind Expansion
In a move towards advancing France's ambitious offshore wind goals, the country's transmission system operator, RTE, has initiated a market consultation process ahead of the launch of a substantial tender for the provision of high-voltage direct current (HVDC) transmisson systems, crucial for connecting future offshore wind farms to the mainland grid.
The consultation, announced in late October 2024, focuses on both underground and subsea links operating at 320 kV and 525 kV. These systems are intended to serve offshore wind projects scheduled for commissioning from 2034 onwards, aligning with France's long-term renewable energy strategy.
By engaging with potential suppliers early, the grid operator aims to optimise and refine its requirements whilst considering the latest available technologies, to enhance the efficiency of the forthcoming procurement process.
RTE has noted that participation in this preliminary consultation will not influence eligibility for the actual tender, encouraging broad industry input without creating any obligations or advantages for respondents.
The scope of the future tender is comprehensive, encompassing engineering, procurement, construction, installation, and commissioning (EPCIC) services. Additionally, it will cover inspection, maintenance, and repair (IMR) aspects, ensuring a holistic approach to cable system management throughout its lifecycle.
This initiative is part of France's broader energy transition plan, which targets an impressive 45 GW of offshore wind capacity by 2050. This ambitious goal is expected to contribute significantly to the nation's energy mix, potentially accounting for one-fifth of its total energy production.
The French government's commitment to offshore wind development is further evidenced by its recent announcement of plans for a tenth call for tenders (AO10). This upcoming round aims to secure between 8 GW and 10 GW of offshore wind capacity, with contract awards anticipated by autumn 2026. This is designed to support France's interim target of 18 GW of operational offshore wind capacity by 2035.
