The TSO Innovation Alliance, composed of eight leading European Transmission System Operators (TSOs)— including Elia, 50Hertz, Swissgrid, RTE, Red Eléctrica, Terna, Amprion, and TenneT — is launching this open call titled " Building a Climate-Resilient Power Grid. " 

We are now calling on tech providers to bring forward solutions in two key areas:

1.     Extreme-weather forecasting and decision support for control rooms – tools and technologies that provide early warnings, impact assessments and recommended actions for operators, from month-ahead to real-time.

2.     Climate-proof network planning and investment – risk maps, hazard scenarios and decision-support methods that help translate climate risk into resilient and cost-efficient planning choices.

Role of the TSOs 

TSOs hold the fundamental responsibility of ensuring the continuous supply of electricity, a prerequisite for delivering power to homes and businesses across Europe at every moment. Equal access to electricity for all is guaranteed, alongside a commitment to providing clean energy for future generations. Activities include the planning, development, and maintenance of the high-voltage transmission grid, combining expertise, cutting-edge technology, and digital innovation to efficiently manage electricity flows. As Transmission System Operators, grid operation — known as balancing — is overseen, continuously matching electricity supply and demand 24/7, 365 days a year. 

Furthermore, the network is designed and developed according to a ten-year development plan that guides the infrastructure evolution needed to meet future energy and climate challenges. 

As Europe transitions toward a decentralized power system dominated by renewables, TSOs face unprecedented operational complexity. Renewable Energy Sources (RES) are weather-dependent, variable, and less controllable. In addition, the power system is vulnerable to extreme weather events which are likely to occur more frequently in the future due to climate change.  

These shifts impact every part of the power system, from long-term investment planning to real-time system operations. Traditional models and decision-making approaches, designed for a more stable and centralized past, are no longer sufficient.  

 
In response, eight European Transmission System Operators (TSOs) have come together to bundle their innovation efforts and define the critical challenges on this journey together. The first topic we tackle together is the use of weather data and grid resilience. The key challenges within this topic span the operational spectrum, from forecasting and real-time response to long-term planning. Together they form a shared roadmap to a smarter, safer, and more climate-resilient grid. The 2 topics are explained in more detail below.
