RB Rail extends electrification tender

Rail Baltica electrification RB Rail has extended the Rail Baltica electrification tender covering design and construction works covering the entire 870 km mainline in Estonia, Latvia, and Lithuania. All potential partners are invited to submit their applications until 14 September 2022.

“While we do not expect that this decision would have an impact on the general procurement timeline, extra time would allow all potential suppliers and partners to ensure higher quality submissions for the qualification stage and to ensure sufficient alignment with potential future partners in this initial tender stage,” Kristjan Piirsalu, Chief Procurement Officer at RB Rail said.

The procurement procedure is carried out in two stages and is planned to be concluded by the end of 2023. The energy subsystem scope covers high voltage connection points, connection of traction power substations to the public high voltage electrical grids, traction power substations, overhead contact system, energy control and command system, and other components directly linked to energy subsystem.

Across the 870 km double-track line more than 2,000 km of catenary system, around 4,350 tonnes of copper materials, and 50,000 masts need to be installed.

At the beginning of 2021, the Rail Baltica joint venture RB Rail selected ENE Engineer as the  engineering service provider for the global project energy subsystem deployment. The association of DB Engineering & Consulting GmbH, Idom Consulting, Engineering, Architecture and Italferr was announced as the winner in an international tender, carried out by RB Rail.

Rail Baltica electrification procurement was launched on 1 June 2022, and is considered the largest railway electrification project in Europe implemented as a single project. It will allow full compliance with safety and interoperability requirements, benefit from economies of scale, as well as maximise the benefits for the environment.

The proposed new electrification architecture static frequency converters (SFC) on a project of such a scale is also one of a kind, providing flexible and efficient integration between countries.
