Subnautica 2 Power Calculator

Estimate whether a starter base has enough power margin for crafting, lights, processing, and vehicle support.

Planning units, not official watts: Early Access output values can change. This calculator uses editable planning units so you can model your base without publishing unverified game numbers as facts.

Solar panel 3 planning units each. Best in shallow light; placement should be retested after patches. Hydroelectric turbine 4 planning units each. Use near reliable current routes; output is planning-only until verified. Thermal plant 5 planning units each. Later-route planning source; exact output and recipe need current-build proof.
