Reactive Technologies, a UK- and Finland-based leader in grid stability measurements, has raised £25 million in Series D funding.

The round was led by M&G’s Catalyst investment, alongside UK and Ireland growth capital investor BGF and Breakthrough Energy Ventures, and support Reactive’s global expansion.

As global renewable energy deployment accelerates, grid operators are grappling with challenges related to grid stability, such as diminishing inertia and system strength. Reactive Technologies addresses these challenges with its pioneering GridMetrix technology, empowering system operators to monitor power system stability in real time. 

This capability enables operators to reduce renewable curtailment, prevent blackouts, and optimise spending on balancing services.

The increasing integration of renewables into power systems worldwide is driving a surge in demand for Reactive’s technology, including its Tradenergy software, designed to help short-term power traders navigate the complexities of a renewables-dominated landscape. 

M&G’s investment is from Catalyst, a £5 billion purpose-led private assets strategy that invests in innovative companies tackling some of the world’s biggest environmental and social challenges.

“This investment from M&G along with our existing investors, BGF and BEV , marks another significant milestone for Reactive Technologies,” said CEO Marc Borrett. 

“As we deliver more projects to support the global transition to Net Zero, this backing will empower us to deliver at scale, expand our commercial presence internationally, innovate further, and make a real contribution to a clean energy future.”

Reactive says its GridMetrix service is already estimated to be saving approximately 18 million tonnes of CO2 annually for the UK power system – approximately 5.5% of total annual UK CO2 emissions. 

The firm has also entered the US market with a large-scale demonstration project in New York State in collaboration with multiple utilities, while it has additional projects on the horizon in the US, Asia, Europe and the Middle East.

“We are proud to back Reactive Technologies, which is fast becoming a British success story,” said Zachary Webb, head of EMEA investments in Catalyst, M&G Investments. 

“Our investment will support the company’s international expansion, potentially transforming how grid systems operate worldwide to reduce unnecessary carbon emissions.”
