answer:You might look at real life power outage examples for ideas to build on. One example Northeast blackout of 2003 Electricity is produced by generators, and boosted or reduced by transformers; no pumps involved. It is transmitted via wires, and the routing is controlled by switches, relays, and software. When the power goes down, it’s very feasible that the cause of the problem is 500 miles away. One big scale Northeast blackout was caused by a 79 cent relay. If you want more drama, go to the source, where the generators are: like a dam or windmill farm. Sabotage, bombs blowing them up, etc.
