Affordable and sustainable primary equipment for Future-Ready multi-terminal HVDC Systems

The Horizon Europe call “Affordable and sustainable primary equipment for Future-Ready multi-terminal HVDC Systems” (HORIZON-CL5-2026-03-D3-19) supports multinational consortia of at least three independently operating partners and aims at the development of small, lightweight, and environmentally friendly primary equipment for multi-terminal HVDC grids. With a funding amount ranging from €4 million to €12 million and a funding rate of up to 70%, the measure targets equipment manufacturers, transmission system operators (TSOs), and research institutions in the EU or associated countries. Projects improving, modularizing, and standardizing circuit breakers, fault current limiters, eco-friendly cables, or converter components are eligible for funding. The project duration is 36 months, and eligible costs include personnel, material and travel expenses, as well as subcontracting services.

Submission requires a consortium with at least two equipment manufacturers, two TSOs, and two research institutions. Applications are possible until 31 March 2026 via the Funding & Tenders Portal; the call opens on 18 December 2025 and follows a single-stage procedure. Selection criteria include the degree of innovation, sustainability, relevance to the European energy market, as well as feasibility and consortium strength. A detailed project description, financial plan, and expertise profiles must be attached. In line with gender equality plans, gender-neutral language is expected, and Open Science principles should be observed. The program contributes to the green and digital transformation of the EU energy market and enhances the resilience, security, and competitiveness of renewable energy solutions.
