To sum up… There is a growing base of ideas on technical and commercial architectures. Demonstration activities around the world are providing us with a ‘proven’ set of tools/techniques/systems/commercial arrangements. The next challenge is defining the architectures that bring these tools/techniques/systems/commercial arrangements together © 2013: Smarter Grid Solutions Ltd. (SC344695). All rights reserved.
