Väylävirasto, the Finnish Transport Infrastructure Agency, is preparing a new service to measure and analyse electrical power quality in the railway overhead contact system, aiming to support maintenance and investment decisions across the electrified network.
On 14th September 2026, Väylävirasto published a prior information notice for an enhanced Electric Power Quality Measurement Service. The service focuses on the overhead contact system that delivers traction power across the railway network.
According to the notice, Väylävirasto wants to monitor and analyse electrical power quality in the railway network and use that information to support both maintenance and investment decisions. The emphasis on analysis as well as measurement indicates that the agency is looking for more than isolated readings; it is seeking insight that can be used in planning and operations.
As a prior information notice, this is an early step in the procurement process. Väylävirasto is signalling its direction of travel to the market and giving suppliers an indication that a competition around power quality monitoring for the overhead contact system is in preparation.
The notice links the planned service explicitly to two core activities: maintaining the existing electrified network and making investment decisions. From a supplier’s perspective, that suggests several priorities:
The notice does not describe specific methods, technologies or performance levels. However, by combining “measurement service”, “monitor and analyse” and “supporting maintenance and investment decisions” in one description, Väylävirasto points towards a package that blends technical measurements with interpretable outputs for decision-makers.
The focus on measurement and analysis in Väylävirasto’s plan reflects themes visible in other recent procurements in energy and transport infrastructure.
In August 2026, Tallinna Tehnikaülikool published a contract notice for an Electrical Measurement Devices Procurement. The university is procuring remote measurement devices, including power quality analysers and wireless current sensor modules, to collect data from electrical systems at customer locations. That notice, like Väylävirasto’s, puts power quality and remote monitoring at the centre of how systems will be understood and managed.
Also in August 2026, UAB Vilniaus viešasis transportas issued a contract notice for Electrical Substation Project Services. That procurement covers measurement, analysis and preparation of technical work projects for the electrical substation system of the Vilnius trolleybus contact network. As with Väylävirasto’s plans for the railway overhead contact system, detailed electrical measurements are being tied directly to decisions about supporting infrastructure.
Water infrastructure has seen similar moves. In July 2026, Państwowe Gospodarstwo Wodne Wody Polskie published a contract notice for a Pump Stations Measurement System Adaptation. The service involves adapting electrical energy measurement systems at ten pump stations to meet Energa Operator’s requirements by replacing existing systems with high-voltage measurement systems and carrying out any necessary reconstruction work. Again, accurate energy measurement is treated as a foundation for compliance and reliable operation.
On the electricity distribution side, Pori Energia Sähköverkot Oy set out a complementary approach in April 2026 with a contract notice for Electricity Network Services. The company is seeking a service provider to deliver high-quality and cost-effective network use services, including 24/7 monitoring, operation and planning, while meeting safety requirements and achieving economic savings. Continuous monitoring and operational insight are at the heart of that contract.
Municipal energy management is following a comparable path. Turun kaupunki (the City of Turku) used an “other notice” in September 2026 to invite companies to a market dialogue webinar for an Energy Monitoring service. The aim is to gather insights on the availability and requirements of an energy consumption monitoring service before procurement.
Across these examples, buyers are not only commissioning works or purchasing physical assets. They are shaping contracts around the ability to measure, monitor and interpret how infrastructure performs in practice.
The interest in the overhead contact system in Väylävirasto’s notice sits alongside other rail-related procurements focused on measurement and electrification.
In July 2026, Rail Equipment GmbH & Co KG issued a prior information notice for a Market Exploration for Rail Measurement Vehicles. Companies are invited to express interest in developing, producing and delivering rail-bound superstructure and overhead line measuring vehicles. While this initiative focuses on rolling stock-based platforms, it shares with Väylävirasto’s plan an intention to embed systematic measurement into how rail infrastructure is assessed.
Centralny Port Komunikacyjny sp. z o.o. moved into full delivery mode in September 2026 with a contract notice for the Design and Construction of Overhead Contact System on a railway line. The scope includes design documentation, construction of the overhead contact system, related power supply elements, reconstruction of associated infrastructure and obtaining the certifications needed for operation. Although that contract focuses on building and certifying new systems rather than monitoring existing ones, it underscores the significance and complexity of the assets that Väylävirasto now wants to observe more closely through power quality measurements.
Together, these rail electrification procurements show measurement and monitoring emerging alongside construction and specialised vehicles as integral parts of the overall system.
Väylävirasto’s description of its planned Electric Power Quality Measurement Service remains concise, as is typical for a prior information notice. Even so, several elements are clear.
Similar combinations of field work, measurement and decision support appear in other 2026 notices. Tampereen Energia Sähköverkko Oy’s June 2026 contract notice on Construction and Maintenance Services for a 20/0.4 kV distribution network seeks two contractors to provide construction, maintenance and measurement services under annual contracts. In May 2026, Oulun kaupunki’s prior information notice inviting a Market Dialogue for Passenger Counting Devices highlights the need to understand technical solutions, feasibility and installation requirements for devices whose data will feed into transport planning in the Oulu region.
Across energy networks, water systems and public transport, these notices show buyers structuring procurements so that measurements and the analysis of those measurements can be fed back into day-to-day operations and long-term planning.
Väylävirasto’s prior information notice is the first public indication of how the Finnish Transport Infrastructure Agency intends to approach power quality in the overhead contact system of its railway network. Detailed requirements, commercial terms and timelines are not yet available, but the emphasis on network-wide monitoring, analysis and decision support is already established.
The next step will be the publication of a full contract notice setting out the scope in more detail. Until then, suppliers active in rail electrification, power quality analysis and infrastructure monitoring can draw only broad signals from this brief description and from the wave of related measurement-focused procurements emerging in 2026.
By linking its planned service directly to maintenance and investment decisions, Väylävirasto is placing data on power quality in the overhead contact system alongside other key inputs into how the electrified railway network is maintained and developed.
