Europe’s race to reach net-zero is putting enormous pressure on its power grids. As demand for electricity rises and is expected to double in the coming decades, renewable energy from wind and solar is flooding the system. Unlike fossil fuels, these sources are variable and decentralized, creating two-way power flows that strain ageing infrastructure and limit capacity. The EU-funded HEROGRID project aims to modernize this backbone of the green transition. Specifically, it will combine high-temperature low-sag conductors, which carry more power with minimal cable drooping, and AI-driven dynamic line rating systems, which adjust grid capacity in real time based on weather and load. Together, they are designed to make Europe’s grids smarter, more flexible, and more resilient.
