Subnautica 2 How to Power Your Base

Power your Subnautica 2 base with stable early placement, fuel planning, terminals, and expansion rules for safer crafting loops.

How to power your base

Choose a base site with reliable access to power components, build only the modules you can support, and keep batteries or fuel materials sorted near the crafting area. A powered base should shorten routes, recharge tools, and support storage before it becomes decorative.

Power planning checklist

Confirm the current power source recipe, build near repeatable resources, leave room for terminals, and test whether your base still functions after adding windows, rooms, or vehicle support. If a route depends on one powered outpost, keep repair supplies nearby.

Co-op power rules

Agree before expanding. One player adding rooms while another drains batteries can break the loop quickly, so call out power changes before major builds.
