Subnautica 2 Power Calculator

Compare generation with the equipment you plan to run together. Enter the power rates from your base, then choose how much spare output to allow.

Use matching rate units: enter generation and consumption as energy per second. Use the same unit for every row. Stored energy is a capacity, so do not enter it as a power rate.
