About Reactive Technologies

Reactive Technologies (RTL) is an innovative energy technology solution provider with the mission to help enable the global renewable energy transition.

RTL’s Grid Metrix® platform is a unique stability measurement service for power grid operators (transmission and distribution), to enable power grid operators more precise control of their grid, therefore operate more safely and cost‑efficiently and utilise more renewable energy in the power systems to help them achieve their Net Zero targets. RTL also offers unique grid insights and forecasts to power traders through it’s Tradenergy® service.

This enables our customers to make smarter and faster trading decisions. We also anticipate using our own grid data to identify new insights to enable new services to be developed more widely across the energy sector.

RTL has approx. 200+ patents granted globally, with offices in the UK, Finland and others being opened around the world.
