The current concept of scaling up is to use multiple dpf units. That way one unit could be down for service while other units carry the load. The units would be deployed in a network similar to cell phone towers. This gives the energy network great resilience in case of natural disasters or sabotage. The cost of long distance distribution systems would be reduced.
As a practical matter, each unit produces a lot of heat in a very concentrated volume. That heat has to be removed fast enough to prevent the electrodes from being damaged. Some of these engineering concerns will be better known when the FF1 unit produces significant power.
