The reconstruction of Warsaw West Station was driven by the need to enhance passenger comfort, safety, and accessibility, as well as to increase the station's capacity, optimize energy costs, and improve efficiency.

From the very beginning, we suggested to the investor the incorporation of renewable energy sources at the station. We conducted economic analyses demonstrating the significant cost savings the investor would achieve.

The architecture of Warsaw West Station must embody timelessness. Railway structures and buildings should serve multiple generations while remaining unique, distinctive, and characteristic of railway infrastructure. Railway architecture is both an art and a "brand," and Warsaw West Station represents a world-class investment.

The largest BIPV installation in Europe, covering an area of 12 000 m2 and generating 1.1 MWp, enables an annual reduction of 650 tons of CO2 emissions.

Warsaw West Station, due to its strategic location, is one of the largest railway stations in Poland in terms of passenger traffic and the number of passing trains. The station has eight platforms and serves domestic, international, and suburban trains. Together with the adjacent PKS bus terminal, it forms the Warsaw West transport hub. However, for many years, the station required renovation to accommodate the growing number of passengers, improve accessibility for people with disabilities, and integrate modern railway traffic control technologies. A new impetus was needed to revitalize this key transportation hub.

The investor's requirements mandated that at least 75% of the eight platforms be covered. As a result, a roof with a total area of 35 000 m2 was constructed. This space was efficiently utilized for the installation of building-integrated photovoltaic (BIPV) systems, supplied by ML System.

The photovoltaic solutions installed in the glazed skylights and on the platform roofs generate approximately 30% of the energy required to operate the entire transportation complex.


The building-integrated photovoltaic (BIPV) system consists of BIPV modules integrated into skylights and BIPV modules installed on the station's roofs. The BIPV modules in the photovoltaic skylights feature an additional glass illumination function, while the BIPV modules on the roofs are equipped with an automatic snow removal function.

The illumination and snow removal systems are operationally supervised by PLC controllers and are managed by the Energy Management System (EMS) from ML System. The EMS controls the photovoltaic installation, the automatic snow removal system, and the illumination system for the skylight modules. It oversees the photovoltaic aspects of all eight platforms simultaneously and serves as a supervisory system in case of a failure in the Building Management System (BMS).

The EMS is deployed on a redundant, virtualized server and features web-based access and automatic backup capabilities. The system integrates over 150 devices in parallel communication, collecting and archiving approximately 5,000 data points in real time. The visualization platform includes more than 100 dashboards, covering various aspects of the system's operation.
