Dr. Keith Sunderland:

On the Deputy's point regarding complications at street level and how to manage that from the perspective of the network, one should look at it in the context of the consumer or "prosumer" and the aggregation opportunities. There is a demand-side response element to this issue. Intelligence at the consumer end looks to optimise the storage vis-à-visthe actual generation. Another thing which was not touched on too much is the potential vehicle-to-grid opportunities. The grid can be supported by the electric vehicle, EV. People are researching this question, but it has not got very far as yet. It is not only an issue for the grid or network, but for the prosumer as well.
