Procurement started for high-speed Rail Baltica project

Public procurement commenced for the design and build of the energy subsystem for the high-speed Rail Baltica project of 870 km connecting Estonia, Latvia, and Lithuania. After completion, it will be the largest railway electrification project in the world.

The contract to comprise the deployment of an energy subsystem in a consolidated way from Estonian capital Tallinn via Latvia to the Lithuania-Poland border, it will then pass between Lithuanian cities of Kaunus and Vilnius.

It will include key components like traction power substations, high voltage connection points from substations to public electrical grids, and energy control command system, an overhead contact system, and other components linked to the energy subsystem.

The 870 km of double track requires more than 2,000 km of catenary systems, around 4,350t of copper materials, and the installation of 50,000 masts. The electricity consumption of Rail Baltica would be in the range of 900GW/h per annum. Which reflects an estimated 3% rise in the national consumption of each of the Baltic States.

The electrification will further involve the implementation of static frequency converters (SFC) to enable flexible and efficient integration within the different countries. The utilisation of SFC on a project of this size is quite unprecedented.

The procurement shall unfold in two stages and will be concluded by the end of 2023.
