Energy tech company Gridraven has won a public tender by Finnish TSO Fingrid to deploy dynamic line rating (DLR) across the country’s high-voltage transmission network.
The contract covers five 400 kV lines totalling 700km and has an option to expand toward national coverage of 5500km by the end of 2025. The project affects how grid capacity is calculated and managed, unlocking flexibility and efficiency without building new infrastructure.
Aiming to increase grid capacity and reduce the need for hardware or sensor installations on grid assets, Gridraven in a release says their software solution provides high-accuracy transmission capacity forecasts through precision weather forecasting. This is based on detailed topography data and advanced AI modelling, achieving precision in challenging terrains.

According to the Estonia-based company, this enables TSOs like Fingrid to operate their power grid closer to physical limits with full transparency and safety. This precision weather forecasting-based DLR technology, they add, promises to unlock up to 30% additional power annually from the existing grid.
Commenting in a release was Mikko Piironen, unit manager at Fingrid: “Dynamic Line Rating enables us to operate our transmission system more efficiently and with better real-time insight into grid conditions.
“Because the solution is fully software-based and requires no physical installations, it allows us to scale DLR across the entire 400 kV network. This project marks an important step in modernizing grid operations and helps maximize the use of existing infrastructure instead of building new lines.”
Said Gridraven’s CEO Georg Rute: “We are proud to be selected by Fingrid as the solution provider for increasing the capacity of their transmission grid.
“This project is globally relevant in demonstrating that sensorless Dynamic Line Ratings offer a scalable, reliable, and rapid way to unlock unused headroom in existing lines. Fingrid is leading the way in embracing innovative solutions, and we’re excited to help accelerate their impact.”
According to Gridraven, the technology has already been field-tested in several pilot environments.
