- 7. Active Network Management in the UK 8 Active Network Management Real-time control of DER, load and the network to make best use of distribution infrastructure
- 8. Smarter Grid Solutions ♦ Successful smart grids manage large numbers of distributed energy resources. The traditional operator-in-the-loop approach won’t cut it anymore. To resolve the grid challenges of a low carbon world, we need real-time, autonomous, deterministic control technology. That’s why we exist. ♦ Founded in 2008 ♦ 7,000 sqft HQ in Glasgow with development and test infrastructure ♦ Offices in New York and London ♦ Over 50 engineers dedicated to the development and deployment of Active Network Management ♦ Over 10 years in development in collaboration with utility customers and one of Europe’s leading power systems universities (University of Strathclyde) 9
