The Coast Guard photos showed their fuel terminal storage tanks to still be intact. I suspect the largest damages to the electrical infrastructure will be in their 34.5 or 12.47kV Electrical distribution system.
Substations probably also experienced numerous faults from crossing lines and numerous safety devices disengaging during the seismic event.
Getting the system back up and running will take a dedicated, concentrated effort by a seasoned group of operating engineers and dispatchers, with a fair amount of corporate knowledge of their system.
I suspect they will first focus on a handful of simple circuits, fully operating, while concurrently inspecting and performing obvious continuity repairs on other circuits.
Getting them all back on line will also require coordination and control of their system to make sure others haven’t back fed the system from localized gensets, which could electrocute linemen working from the source.
Best bet is probably a distribution of smaller gensets to communities for some decentralized logistics to run concurrently with manual labor and distribution of basics, (cleaning up roadways, foods and water and medical and communication via standalone stations, tool recharging, etc).
If that can get rolling, then it will keep the people busy constructively, within their own decentralized availability of resources, until more centralized logistics can be returned to normal cultural flows.
Generally speaking, the most efficient delivery of resources is by re-establishing existing utility networks and traffic patterns. Their operations and utility are already understood by the people, and much less communication and management is required to operate them efficiently.
Unlike floods and hurricanes, the materials are still where they were when the quake hit. Just structural repairs and connections must be re-established, and electrical systems will take longer to re-energize safely to avoid highly dynamic loading on their systems.
