"Fuel cells, solar thermal generating stations, photovoltaic fields, wind farms, diesel, natural-gas-fired turbines, microturbines and other renewable and non-renewable sources of energy can be aggregated in a microgrid….. a microgrid could automatically detach from the greater grid and continue to deliver power to sectors of customers in abnormal conditions. And this would enable utilities, too, to more strategically and efficiently deploy resources to damaged areas of the grid to make repairs and restore service."
