Reactive Technologies, the UK and Finland based grid technology company, has announced a new group of investors as part of a $15M fundraise – the business’ largest ever. The funding round was led by the UK & Ireland’s most active investor, BGF, alongside Breakthrough Energy Ventures, and Eaton.  Reactive will use the proceeds to expand its international activities and export its technology to countries around the world that are experiencing rapid renewable energy growth and already beginning to manage the challenges of decreased grid stability caused by a loss of inertia.
