Power and thermal continuity since 1989
Helios
Keeps the lights on at sites where nobody is coming to help.
Islanded generation, storage and thermal management for remote stations. Helios assumes no grid, no fuel delivery for the season, and no engineer on site, and is designed to shed load in a defined order rather than fail as a unit.
Purpose
Islanded power and thermal continuity for remote stations when no one is coming.
Architecture
- Deterministic load-shedding order, rehearsed annually
- Multi-season autonomy at reduced draw
- Thermal envelope maintained ahead of compute
- Manual override reachable without power
Design constraints
- Assume no fuel delivery for the season
- Habitat heat outranks jobs
Failure modes
- Operators who reorder the list under pressure
- Compute kept warm while people are not
Historical development
Long-running programme; public load order in SEN-04-029.
Known limitations
- Cannot invent fuel
- Cannot make NORTHLINE answer
We do not claim systems are perfect. We document how they fail.
