Reactive Technologies: Grid inertia, system strength and waveform measurement

Reactive Technologies supplies grid-stability measurement and analytics through GridVerix, XMU sensing hardware and an OEM technology-licensing programme.

Summary

Best for
Utilities investigating inertia, system strength and oscillations as inverter-based resources grow.
Less suited to
Building energy billing or treating measurement analytics as a protection relay.
Deployment
Distributed XMU measurements, active modulation where applicable, and GridVerix analytics.
Data in
Time-synchronised electrical waveforms and measured network responses.
Pricing
Grid measurement deployments and OEM technology licences have different scopes; the reviewed pages do not publish standard prices.

Overview

Reactive Technologies measures properties of electricity networks that are difficult to infer reliably from an asset inventory alone. Its current GridVerix platform combines high-resolution sensing, active measurement and analytics. The company explicitly identifies GridVerix as the new name for GridMetrix, so older project announcements refer to the same platform lineage.

The principal applications are inertia measurement, system-strength measurement and oscillation monitoring. These address different aspects of grid behaviour. Inertia concerns the response of frequency to imbalance, while system strength and oscillatory behaviour require additional measurement and analysis. The offering is intended for network operators and specialist power-system work, not ordinary premises-level consumption reporting.

Offering

The platform architecture uses XMU and XMU2 devices for measurement and processing close to the network. They can operate as dedicated measurement devices or supplement existing phasor measurement units and digital fault recorders. GridVerix combines observations across locations into a coordinated analytical view.

The Nyquist licensing programme is a separate route for OEM partners to integrate selected measurement, processing and analytical technologies into their own products. Its XMU2 description includes an eight-channel, 24-bit acquisition architecture with precise time synchronisation and embedded computing. This is more specific than a general cloud-dashboard licence: it can involve the measurement architecture and processing technology that feed the software.

Technology

Reactive's active-measurement approach introduces controlled modulation and analyses the network response, rather than relying only on naturally occurring disturbances. Sensing and time alignment across locations are central to interpreting that response. The oscillation-monitoring application uses continuous point-on-wave data to examine behaviours that can be difficult to see in slower or snapshot-based measurements.

The Nyquist technical description discusses high-frequency waveform acquisition and interfaces to other measurement assets. These capabilities do not make every listed analytical feature a finished product: the platform page marks some emerging-phenomena analysis as coming soon. A project should therefore distinguish the available measurement functions from the roadmap and the particular technology licensed to an OEM.

Markets

Reactive's HEPCO announcement describes frequency visualisation, oscillation monitoring, inertia measurement and event analysis for a Japanese electricity company. The application combines several views of network behaviour rather than reducing grid stability to one dashboard number.

The current NESO case study describes direct, real-time inertia measurements supporting the British system operator's operational decisions. It connects that visibility with reducing conservative assumptions as renewable generation increases. These are different applications of measurement-led grid operation: the HEPCO project combines frequency, oscillation and inertia observations, while the NESO case focuses on operational visibility of inertia. OEM partners can instead license measurement and processing technology through the separate Nyquist programme.

Company

Reactive Technologies dates its founding to 2010 on its current company page. Its HEPCO release identifies London as the headquarters and Finland as an R&D centre, alongside commercial operations in other regions.

The current leadership page names co-founder Marc Borrett as CEO and Ville Kampman as Group CTO and CEO Finland. The company has retained its specialist focus on electrical-network measurement while extending the architecture into OEM licensing and broader waveform analysis. The GridVerix rename changes the product identity, while the historical GridMetrix projects remain relevant evidence of its development and deployment.
