London-based Reactive Technologies has secured €19m in venture debt from the European Investment Bank, with up to €7m earmarked for research in Finland and the remaining €12m for deploying its GridVerix platform across the EU.
Reactive Technologies, the London grid-technology company founded in 2010 by Marc Borrett and Dr Heikki Huomo, has raised €19m from the European Investment Bank (EIB) in a financing that does not involve a new priced equity round.
The facility is structured as venture debt and is backed by InvestEU, the EU programme that underwrites EIB lending to strategic sectors. It also counts towards TechEU, the EIB Group's initiative to accelerate investment in technologies it regards as critical to European competitiveness.
The loan comes in two parts. Up to €7m is ring-fenced for research and development at the company's centre in Oulu, central Finland. The remaining €12m will fund roll-out of its technology within the European Union.
Terms were not disclosed. The interest rate, maturity and any warrants or equity-linked features attached to the loan have not been made public, and the company has not disclosed a valuation.
For a business now in its sixteenth year, the choice of debt over a fresh equity round is the cap-table story. It funds expansion without resetting the company's price or diluting existing shareholders, provided the loan is serviced from growing revenues.
Reactive Technologies sells GridVerix, a platform that gives network operators real-time readings of grid stability. Its core measurement is inertia: the kinetic energy stored in spinning generators that helps a power system ride out sudden disturbances. The platform also tracks the strength and stability of voltage across different parts of a network.
Those readings matter more as the generation mix changes. Wind and solar farms provide little of the inertia that conventional plants supply, while large new loads such as data centres add complexity. The company says its data helps operators identify weak points, connect more renewable capacity and reduce curtailment, the deliberate switching-off of clean generation that ultimately adds to consumer costs.
Borrett, the chief executive, said the EIB's support came at a critical moment, with the growth of renewables and large power consumers making Europe's grids harder to manage. He said real-time stability data would help operators keep systems secure, run them more efficiently and cut costs for consumers.
Karl Nehammer, vice-president of the EIB, said Europe needed grids able to keep pace with renewable growth, adding that the bank's financing would help take the technology to more markets and reduce the risk of power outages.
Although headquartered in London, Reactive Technologies runs commercial offices on the east and west coasts of the US, in the UAE and in Australia, alongside its Finnish R&D base. Its sales and project-delivery teams serve customers worldwide.
The €12m deployment tranche points to a push for contracts with EU grid operators. The deal also places Reactive Technologies among a number of UK deep-tech companies using public-backed lending, instead of new equity, to fund capital-intensive growth.
