Reactive Technologies has secured €19 million in European Investment Bank financing to expand its GridVerix power system monitoring platform, dividing the funding between research in Finland and wider deployment across European electricity networks.
Up to €7 million of the venture debt package will support research and development at the company’s centre in Oulu, while €12 million will support deployment in the European Union. The financing is backed by InvestEU and contributes to the EIB Group’s TechEU programme for strategic technology investment.
GridVerix provides real time measurements of grid stability, including inertia and the strength and stability of voltage across different parts of a network. The company uses distributed measurement equipment and central analysis to give operators a direct view of system behaviour as generation, demand and network conditions change.
Inertia has traditionally been supplied naturally by the rotating mass of large synchronous generators. Stored kinetic energy in those machines helps slow the rate at which system frequency changes when a generator, major load or transmission asset is unexpectedly lost. As electricity systems add more inverter connected wind, solar and battery capacity, that physical characteristic changes and operators need better information about the amount and location of stability available.
Grid strength presents a related engineering problem. Renewable projects, storage plants, data centres, industrial loads and other large connections do not interact with every part of a transmission or distribution system in the same way. Voltage conditions and the ability of the network to remain stable can vary significantly by location and operating state.
Marc Borrett, chief executive officer of Reactive Technologies, said: “The rapid growth of renewable energy and large power consumers such as data centres are making Europe’s grids more complex to manage.”
The EIB financing is intended to take measurement capability developed by the UK and Finnish company into more European networks rather than limiting the programme to further laboratory work. That distinction matters because grid monitoring technology has to be integrated with existing operational systems, installed at suitable network locations, maintained and converted into information that dispatch, planning and engineering teams can use.
The platform is based on direct measurement rather than relying solely on network models. That does not replace conventional power system studies, which remain essential for planning, fault analysis, protection settings, connection assessments and investment decisions. Measurement instead provides another layer of evidence where system characteristics vary quickly or where uncertainty in a model can force operators to adopt conservative operating limits.
That conservatism carries a direct cost. When operators are uncertain about system stability, they may constrain renewable generation, procure additional balancing services, retain conventional generation for stability purposes or limit new connections until reinforcement is available. Better measurement does not create transmission capacity, but it can give engineers a stronger basis for determining how existing infrastructure can be operated safely.
The EIB specifically links GridVerix to renewable integration and the growth of large electricity users such as data centres. The two trends place different pressures on networks. Variable generation changes power flows and the location of operating reserves, while a large data centre can add hundreds of megawatts of concentrated demand in an area where connection capacity is already limited.
Reactive Technologies is headquartered in London and operates its advanced research centre in Oulu. The Finnish site gives the business a technical base inside the EU, while the €12 million deployment element provides capital for expanding the commercial footprint of the technology across member states.
The support takes the form of venture debt rather than equity. For a growing technology company, that can provide additional capital without issuing another large block of shares, although the financing still has to be supported by commercial progress and continued demand for the underlying product.
The engineering case for direct stability measurement will also be tested against the practical needs of network operators. Utilities have established control systems, asset data, modelling tools and operating procedures, and new platforms have to fit into those environments without adding another source of data that engineers cannot act on quickly.
Measurement accuracy, installation effort, communications reliability and the ability to interpret changing system conditions will therefore matter as much as the headline financing. The technology has to produce information that is trusted during normal operation and useful when conditions are moving rapidly.
The €19 million package gives Reactive Technologies resources to continue technical development and expand deployment. The next evidence will come from operating networks, where GridVerix will be judged on whether better visibility helps engineers integrate generation and large loads while maintaining system security and controlling the cost of intervention.
