Security of Supply

By making use of a series of overlapping island networks customers are unaffected by power cuts in the national grid since embedded generation can continue to operate on private wire islanded networks. Although the UK already has a small amount of embedded generation, when the grid is down CHP/renewables are also down unless they have been set up as private wire island networks. Island generation able to supply full load in an isolated environment for prolonged periods of time provides additional security of supply taking advantage of distributed embedded generation that does not rely on the efficacy of the grid.
