The Power Distribution Trunk Network is Ouroboros Energy's proprietary grid infrastructure that connects their Tokamak reactors, Helion portable units, and SolarHarvest ground stations into a unified power distribution system. The TrunkNet uses superconducting transmission cables cooled by integrated cryogenic systems to deliver electricity with near-zero transmission loss between generation points and consumption points. The cables run through dedicated conduits beneath GLMZ's streets, branching from major trunk lines into progressively smaller distribution feeders that ultimately connect to individual buildings.

The TrunkNet's distinguishing feature is its metering and control granularity. Ouroboros can monitor and control power delivery at the individual circuit level — not just by block or building, but by floor, room, and outlet. This granularity enables their dynamic pricing model: electricity costs fluctuate by the minute based on demand, time of day, and the customer's contract tier. Peak-hour power in a Tier 1 district might cost 10 times what the same kilowatt-hour costs in a Tier 5 corporate headquarters at 3 AM. The metering system also enables precise load shedding — during supply constraints, Ouroboros can selectively reduce power to specific consumers while maintaining full supply to priority clients.

The TrunkNet's control infrastructure represents a single point of failure for GLMZ's entire power supply. A successful attack on the TrunkNet control systems could disrupt power to the entire city simultaneously. Ouroboros protects the control infrastructure with multiple layers of physical and digital security, including dedicated Arcturus Defense Solutions security teams at key network nodes. The redundancy built into the physical network — multiple paths between any two points, automatic rerouting around damaged segments — makes physical disruption difficult but not impossible. The greater vulnerability is in the software: the control systems that manage the entire network are proprietary, opaque, and maintained by a relatively small team of Ouroboros engineers whose loyalty is, ultimately, to their employer.
