Why should power plants have interconnection capability?

Having interconnection capability in power plants is essential primarily because it facilitates a degree of resilience and reliability in the face of disruptions, such as attacks or natural disasters. When power plants are interconnected, they can share resources and generation capacity, which helps to sustain electrical generation and maintain grid stability even when one or more facilities are compromised or shut down. This interconnectedness allows for load sharing and enables backup support, thereby minimizing the impact of a failure in any single unit.

While the other choices present aspects that might seem relevant, they do not capture the primary advantage of interconnection. Reducing reliance on a single fuel area or decreasing demand to operate on a single unit does not address the necessity for a resilient and flexible power supply. Similarly, while distribution is important, it is not specifically the aspect that provides the strongest survival advantage in the context of interconnection during emergencies or disruptions. The focus on ensuring ongoing electrical generation capacity post-incident clearly highlights the critical need for power plant interconnections.
