Rail Baltica: Powering High-Speed Rail in the Baltics

The Rail Baltica Energy Subsystem: A Deep Dive into Stage 1 Procurement

The Rail Baltica project, a significant undertaking spanning Estonia, Latvia, and Lithuania, aims to create a high-speed rail link across the Baltic states. This ambitious project encompasses more than 870 kilometers (km) of new track and requires a sophisticated and robust energy subsystem to power the high-speed trains. This article will explore the first stage of procurement for the Rail Baltica energy subsystem, examining the successful applicants, the technical challenges involved, and the broader implications for the project’s success. We will delve into the specifics of the selected design, focusing on its innovative aspects, and analyze the competitive bidding process, highlighting the capabilities and experience brought by the shortlisted consortia. Furthermore, we will discuss the project’s timeline and the significance of this crucial step in the overall Rail Baltica development.

The Applicant Consortia: A Blend of International Expertise

The selection process for the design and construction of the Rail Baltica energy subsystem attracted four prominent international consortia. These groups bring together a wealth of experience in high-speed rail electrification projects worldwide. The successful applicants include:

• Cobra Instalaciones y Servicios S.A. (Cobra Instalaciones y Servicios and Elecnor Servicios y Proyectos S.A.U.) from Spain
• ALSTOM-BMGS-GE-Torpol (BMGS (Bombardier Transportation Baltics), ALSTOM Transport, GE Energy Power Conversion France, TORPOL) from Latvia, France, and Poland
• STC Baltic Electrification (COLAS RAIL AS, Siemens Mobility, Siemens Mobility Oy Latvijas filiāle, TSO SAS) from France, Germany, and Latvia
• Yapı Merkezi İnşaat ve Sanayı from Turkey

Each consortium brings unique strengths and technological capabilities to the table, promising a competitive and innovative approach to the project.

Technological Innovations: The 2x25kV Static Frequency Converter System

A key element of the Rail Baltica energy subsystem is the innovative use of a 2x25kV Static Frequency Converter (SFC) architecture. This technology represents a significant departure from traditional electrification methods and offers several advantages. SFC systems provide flexible and efficient power distribution, enabling seamless integration of the railway energy subsystem across national borders, overcoming challenges often encountered in multi-country projects. The scale of implementation in Rail Baltica, making it a pioneering example in high-speed railway electrification, represents a significant technological leap forward. This system’s efficiency and flexibility are crucial for managing power across the diverse geographies and operational demands of the network.

Project Timeline and Future Stages

The procurement process is structured in two stages. Prequalified candidates submitted their technical and financial proposals by the end of 2022. The second stage involved further evaluation and proposal submission, with a planned contract signing by the end of 2023. The scope of the energy subsystem design and construction includes traction power substations (TPSS), the overhead contact system (OCS), and the comprehensive energy control and command system (ECCS). This encompasses all components essential for the full operational functionality of the high-speed rail network.

Conclusions: A Milestone in Baltic Rail Development

The selection of these four international consortia for the Rail Baltica energy subsystem represents a pivotal moment in the project’s development. The innovative 2x25kV SFC system, chosen for its efficiency and cross-border integration capabilities, highlights the project’s commitment to cutting-edge technology. The consortium members, each bringing significant expertise in high-speed rail infrastructure, signal a robust and competitive approach to the project’s execution. The successful completion of this stage is crucial for the overall timeline of the Rail Baltica project and represents a significant step toward establishing a modern, high-speed rail network across the Baltic states. The meticulous two-stage tender process ensures the selection of a highly qualified consortium capable of delivering a state-of-the-art energy system that meets the rigorous demands of high-speed rail operation. The project’s innovative reliance on Static Frequency Converters (SFCs) will offer a scalable and adaptable solution that is also cost-effective and environmentally conscious, positioning Rail Baltica as a leader in high-speed railway energy infrastructure. The successful implementation of this subsystem will be a benchmark for future high-speed rail projects globally, showcasing the benefits of international collaboration and technological advancement. The completion of the project will have a profound impact on regional connectivity, economic development, and the overall transportation landscape of the Baltic region. The strategic importance of the Rail Baltica project cannot be overstated, and the successful procurement of its energy subsystem marks a major step forward in the realization of this ambitious undertaking.
