Dynamic ratings on Estonia's full network

Gridraven is working with Elering, the Estonian TSO, on a full-network DLR pilot covering 5500 km of 110 kV and 330 kV lines.

Full-network DLR pilot

Gridraven has partnered with Elering, Estonia’s transmission system operator, to conduct a pioneering Dynamic Line Rating (DLR) pilot across Elering’s entire network. This initiative aims to explore how DLR technology can enhance grid capacity to support Estonia’s ambitious goal of achieving 100% renewable energy by 2030.

Boosting all lines, including 110 kV

By implementing DLR with span-level resolution, Gridraven is enabling real-time monitoring and optimization of transmission line capacities, including 110 kV lines in forested areas. To ensure accuracy, eight weather stations have been installed for validation, providing critical data to maximize the integration of renewable energy sources into the grid.

This collaboration marks a significant step toward a sustainable energy future, leveraging advanced technology to meet Estonia’s renewable energy targets efficiently.

A quarter of lines limit capacity between Estonia and Latvia

A quarter of 330 kV lines limit transmission capacity between Estonia and Latvia. Further, within each of those lines, nearly every span of each line might be limiting at some point in time. Dynamic Line Ratings need to cover a quarter of all spans in the network to maximize transmission capacity.
