Eight leading European Transmission System Operators (TSOs) have joined forces to launch the first TSO Innovation Alliance Open Call: Building a Climate-Resilient Power Grid. The Alliance recognises that innovation is essential and is therefore reaching out to technology providers, start-ups, scale-ups, research institutes and established companies to ask them to collaborate. Only by working together can we strengthen Europe’s electricity system against extreme weather and plan infrastructure that will remain resilient for decades to come.
Europe’s power system is becoming more weather-dependent and more interconnected across borders. Climate-driven events, storms, floods, heatwaves and wildfires are increasing in frequency and severity, placing new demands on grid operations and long-term planning. Traditional deterministic methods and static assumptions are no longer sufficient when faced with rising uncertainty and rapidly changing conditions. The TSO Innovation Alliance (Swissgrid, Elia Group, 50Hertz, TenneT, Terna, RTE, Red Eléctrica and Amprion) is inviting the technology community to help accelerate practical solutions that can be deployed and scaled across Europe.
Two urgent topics
Why participate?
Selected technology providers will:
- Collaborate directly with eight European TSOs.
- Fast-track their solutions into Proofs of Concept with real operators.
- Gain a unique opportunity to scale solutions across borders.
Details about expected pilot outcomes and integration preferences are available on the Open Call page.
Key dates
- Open Call period: 1 October – 7 November 2025
- Selection days: 27 November – 5 December 2025
- Start of Proof of Concepts: January 2026
About the TSO Innovation Alliance
The TSO Innovation Alliance is a joint initiative of Swissgrid, Elia Group, 50Hertz, TenneT, Terna, RTE, Red Eléctrica, and Amprion. Together, they represent a significant share of Europe’s transmission network.
Europe’s energy transition brings challenges that cross borders and can no longer be solved by individual TSOs alone. The Alliance recognises that innovation is necessary to keep the grid reliable, affordable and sustainable. By working openly with technology providers and broader society, the Alliance aims to accelerate solutions that strengthen resilience and safeguard energy security.
The programme is multi-annual by design, and will address a series of topics over the coming years. The current Weather & Grid Resilience Open Call is the first step in this long-term effort to build a future-proof European grid.
