Mr. Robin McCormick:

They would then have to produce more energy than they are using. Work needs to be done in terms of how they are rewarded for bringing energy back onto the grid. The bulk of the issue relates to the distribution network and how it impacts on the lines that are already connected to houses because the distribution system is designed as a radial feed and if there is energy coming back up the pipe, work needs to be done to that network to manage that.

From our perspective, it has less impact on our system because we are used to dealing with significant amounts of generation on the system as opposed to the marginal changes that micro-generation would bring.
