A beam corridor's upkeep bill splits the regions it keeps lit

Here is the beautiful part, before the argument swallows it: a single beam corridor from the Solaria Array carries enough power to run three desalination plants at once. Two-plus gigawatts, thirty-six thousand kilometers of vacuum, landing on a rectenna mesh in the coastal basins as gently as rain. It has done this every day for years. Almost none of it is lost.

Now the ugly part. The corridor needs a refit. Antenna elements degrade. Phase-control electronics drift. The field's yield has slipped nearly four percent since its last overhaul. Solaria Array Control has scheduled the work: eleven days, during which the corridor drops to a maintenance trickle while crews swap panels and recalibrate the receiving array.

Eleven days of dimmed power is a schedulable inconvenience. The bill for the refit is not.

"The physics is settled. The invoice is a war," said Adaeze Okonkwo, the maintenance coordinator running the refit from Control. She has the yield curves memorized. The cost-share dispute, by her own admission, is what's keeping her up.

The corridor serves both established coastal basins and two newer inland settlements built during the retreat. Under the current formula, upkeep splits proportional to draw — pay for the watts you pull. The settlements want it split by contribution instead, arguing that the older basins have leaned on this infrastructure for decades and should carry the legacy weight. The established basins answer that draw is draw, and that rewriting the formula every time a bill comes due is how shared infrastructure stops being shared.

"We are not asking for charity. We are asking not to subsidize a system whose life we did not spend," said Teodora Vlasenko, who negotiates energy shares for the inland settlement of Karst Hollow. She put the refit's cost to her settlement at nearly nine percent of its annual stewardship-credit budget, for a corridor it did not commission and cannot reroute.

The basins' representatives declined a joint statement but circulated a memo through the Orbital Exchange noting that draw-proportional shares have funded corridor maintenance since the Accord, and that the settlements' proposed formula would shift roughly a third of the refit's cost onto the regions that use the corridor least.

Here's why none of this is abstract. A corridor that moves three desalination plants' worth of power isn't a knob you turn. It's an argument you make in watts, and whoever holds the schedule holds the leverage. The refit is technically necessary and diplomatically radioactive for the same reason: dimming the corridor, for any cause at all, reminds everyone downstream exactly how much they depend on it.

Control proposed staging the work in two windows to soften the draw-down. Crews say a clean eleven-day dark is faster and safer than two interrupted ones. The Assembly of Signatories has been asked to arbitrate the cost split. It has not scheduled the matter.

The refit crews launch on the next transfer regardless. "The panels degrade whether or not anyone agrees who pays," Okonkwo said. "That part isn't political. Everything after it is."
