PAFW and resource deficiency

Power failure

If there is insufficient power to supply all buildings, they fail in a specific order until supply meets usage. All units of a building fail at the same time: if there is only enough power for nine out of ten Mines, all Mines fail.

Only certain buildings actually cease to function when affected by a power outage. Some fail partially, while others fail in an unexpected manner.

Unexpected failure modes

When Gravity Nullifier switches off due to a power outage, it does not automatically switch itself back on when power is restored.

When Laser Turrets fail, all other turrets fail also. This includes the turrets of Protected buildings.

Medical Centres cannot treat radiation sickness in a power outage, but can still end a virus outbreak.

Repair Facility can still fail during a power outage even though it consumes no power.

If you have the Improved Sensors blueprint, your improved sensor range fails whenever Sensor Array would fail, even though Improved Sensors do not consume power.

Air, food and water shortages

Each colonist needs one unit of air, food and water per day. If production is insufficient, the remaining colonists consume from stored surplus, triggering a “resource deficiency” status and orange colour readout.

Red colour occurs when production is insufficient and there is no surplus, leaving the remaining colonists with no air/food/water. Those colonists are killed at the following rate each day:

Additionally, for each resource in the red, social unrest increases by +2 points per day.
