Lithuanian transmission system operator LitGrid is beginning the modernisation of the strategic 330 kV Aizkrauklė–Panevėžys line, which connects the Lithuanian power system with Latvia. Following completion of the design phase and obtaining building permits, a tender for the construction work has been announced. The investment is not only intended to increase the reliability of the grid, but also to play a key role in the energy transition of the Baltic region.

The modernisation will involve the complete replacement of infrastructure along an 83 km section – from the transformer station in Panevėžys to the border with Latvia. The current single-track line will be replaced with new structures that will allow for the addition of a second track in the future. This will significantly increase energy transmission capacity and the possibility of integrating new renewable sources into the system.

As emphasised by LitGrid CEO Rokas Masiulis, the Aizkrauklė–Panevėžys line is particularly important for the development of wind and solar farms in northern Lithuania, where investors are planning a number of new projects. Without strengthening the transmission network, the connection of large RES capacities would be limited. The modernisation will ensure their effective use, supporting the achievement of climate and energy transition goals across the region.

The project also respects the environment and cultural heritage – the line runs through Natura 2000 areas and archaeological sites, so solutions have been designed to minimise the impact of the works on nature and historical monuments. Work is scheduled to begin in 2026, with completion and commissioning of the upgraded line by the end of 2028. This investment will provide Lithuania and Latvia with a stronger, more flexible energy connection, creating a solid foundation for further expansion of renewable energy.
