As part of the Port Polska railway investment program, Centralny Port Komunikacyjny (CPK) has launched a competitive dialogue procedure to award the contract for the design and construction of traction substations on two high-speed lines in Poland.
The deadline for submitting bids is June 15.
The lines in question are Warsaw – Łódź and Łódź – Wrocław, and the initiative follows the signing of agreements for connection to the power grid with the operator Polskie Sieci Elektroenergetyczne (PSE).
The contract covers the development of technical and detailed designs, as well as the construction of three traction substations. Two of these will be located near the future Centralny Port Komunikacyjny airport and northeast of Łódź (Dmosin), serving railway line 85, which will connect Warsaw, the new airport, and Łódź. The third substation, located on the route to Wrocław, in the Kuźnica–Czajków area, will power line 86 between Sieradz and Wrocław.
The contract also includes an option for the construction of two additional traction substations for Poland’s two high-speed lines. In total, the project involves the construction of five traction substations, designed to operate under the new 2×25 kV power supply standard, introduced for the first time on the Polish railway network. This system is essential for achieving speeds of up to 350 km/h on high-speed lines.
The power infrastructure of Poland’s future high-speed network
The procurement procedure is structured as a “turnkey” contract, which includes complete design, obtaining all necessary permits, construction, as well as certification and commissioning of the traction substations.
In the first stage, applications will be collected from companies and consortia interested in participating in the competitive dialogue. Subsequently, up to seven bidders will be selected for the technical and commercial discussion phase.
All facilities will be powered from the 400 kV and 220 kV high-voltage transmission grid operated by Polskie Sieci Elektroenergetyczne (PSE), with which connection agreements have already been signed for the Warsaw–Łódź section of the high-speed network.
A key element of the project is the traction power supply control and monitoring system, which will manage both the substations and the entire associated power infrastructure. The railway network under the Port Polska program will operate in parallel on two standards: 3 kV direct current for conventional lines and 2×25 kV alternating current for the “Y” high-speed main line, which will connect Warsaw–Łódź–Poznań/Wrocław.
Currently, Centralny Port Komunikacyjny is already conducting similar procedures for the design and construction of two sections between Warsaw and Łódź: Kotowice – the airport junction and the airport junction – Bolimów.
According to the current schedule, the Warsaw–New Airport–Łódź section of the “Y” line is planned to be put into operation in 2032, and the high-speed connections to Poznań and Wrocław are estimated for 2035.
