Now, let's address a scenario where the zombification process is gradual. If the operators and utilities had sufficient advance warning they could take measures to keep the power going for a while. The first thing would be to isolate key portions of the grid, reducing the interties and connections, and then cease power delivery altogether to areas of highest zombie density. After all, it's not like the zombies need light to read or electricity to play Everquest. Whole blocks and zones would be purposely cut off to reduce the potential drains (and to cope with downed lines from zombies climbing poles or driving trucks into transformers). Operators would work to create islands of power plants wherever possible, so if a plant were overrun by zombies and went down it wouldn't drag others down with it. In cooperation with regional reliability coordinators, the plant operators would improve plant reliability by disabling or eliminating non-critical alarm systems that might otherwise shut down a power plant, and ignoring many safety and emissions issues.
