Implementation Practicalities
The SSG relies on existing technology. The SuperSmart Grid would employ high voltage direct current (HVDC) cables in its first-generation implementation to integrate the European electricity market and possibly connect it to neighboring regions, such as North Africa, and their vast renewable energy resources, such as those that could be unlocked by the DESERTEC & Medgrid project. The SuperSmart Grid would operate 'on top' of the local high voltage AC (HVAC) grids. Existing AC grids would still transmit electricity over shorter domestic distances, but be upgraded to smart grids.
Dr Gregor Czisch of Kassel University, has constructed and optimized a model indicating that an entirely renewable electric supply system is possible at today's electric prices.
