If your power transmitters are not working in Subnautica 2, your hydroelectric turbine will not connect, or your Metal Farm suddenly has no power, you are dealing with one of the game’s most common Early Access bugs right now.
A lot of players are running into broken power grids, failed relay connections, and turbines refusing to link properly after rebuilding bases or moving structures. The good news is that there are several workarounds that can usually fix the issue until the developers release a proper patch.
Here’s why the Subnautica 2 power transmitter bug happens and how to fix it.

Why Your Power Transmitters Are Not Working in Subnautica 2
The current Subnautica 2 power system appears to have issues with how structures connect to the same power network.
According to community reports, Hydroelectric Turbines and Metal Farms often cannot connect directly to each other. Instead, both structures usually need to connect through a habitat or base module first.
That means this setup may fail:
- Hydroelectric Turbine → Power Transmitter → Metal Farm
But this setup works much more reliably:
- Hydroelectric Turbine → Base/Habitat → Metal Farm
Players also report that older or nearby bases can remain “ghost connected” in the background. Even if structures visually appear connected correctly, the internal power grid may still be linked to an old base ID, causing the relay system to break.
How to Fix the Subnautica 2 Power Connection Bug
If your turbine is not connecting or your Metal Farm is not receiving power, these are currently the best fixes. Right now, the Subnautica 2 power system can become unstable after moving structures, expanding your base, or rebuilding nearby habitats.
Many players have reported that power transmitters visually appear connected while the internal network fails to recognize them properly. Fortunately, a few simple workarounds can usually get your base powered again until the developers release a full fix for the Early Access bug.
Connect Everything Through a Habitat Module
The most reliable workaround is using a base piece as the center of your power network.
To do this:
- Build a small habitat or corridor near the turbine
- Connect the Hydroelectric Turbine to the habitat
- Attach the Metal Farm to the same powered base
- Rebuild nearby power transmitters if needed
Right now, the game handles habitat modules more consistently than standalone relay chains.
This is currently the best fix for:
- Subnautica 2 turbine not connecting
- Metal Farm power issues
- broken power transmitter networks
Rebuild Your Power Transmitters
Sometimes the relay system simply bugs out after moving structures, expanding your base, or loading a save.
Try:
- removing all nearby power transmitters
- rebuilding them one at a time
- shortening the distance between each transmitter
- reconnecting the turbine after rebuilding
Even when cables visually appear connected, the internal power grid may still fail to register properly.
Save and Reload After Reconnecting
Several players report that the Subnautica 2 power grid refreshes correctly after reloading the game.
After rebuilding:
- Save your game
- Quit to the main menu
- Reload the save
- Check the power network again
This sometimes forces the game to recalculate transmitter and habitat connections.
Avoid Building Multiple Bases Too Close Together
Another common cause of the Subnautica 2 base power bug is overlapping habitat networks.
Players discovered that:
- old bases may stay linked internally
- turbines can connect to the wrong habitat
- Metal Farms may remain attached to deleted structures
- deleting one base can unexpectedly refund connected objects
To avoid this:
- fully disconnect old bases before rebuilding
- move turbines away from abandoned structures
- avoid stacking multiple small bases too closely together
Best Temporary Fix for the Subnautica 2 Power Grid Bug
If nothing else works, this full reset method currently has the highest success rate.
A lot of players report that once the Subnautica 2 power network becomes desynced, simply moving transmitters or reconnecting cables is not enough to fix the issue. In many cases, the game continues treating old structures as part of the active grid, even after they have been removed or rebuilt.
Because of that, doing a complete power network reset is currently the most reliable workaround for broken turbine connections, Metal Farm power failures, and relay transmitter bugs.
Complete Power Network Reset
- Disconnect every transmitter and power structure
- Save and reload the game
- Build one fresh habitat module
- Connect the Hydroelectric Turbine first
- Connect the Metal Farm second
- Rebuild all power transmitters last
Players say the order here actually matters. Connecting the turbine to a fresh habitat before rebuilding the relay chain seems to force the game to create a clean power network. Rebuilding transmitters last also helps prevent old or bugged connections from carrying over into the new setup.
This workaround fixes the issue for many players dealing with the Subnautica 2 relay transmitter bug, especially after base expansions or rebuilding nearby structures.
Is the Power Transmitter Bug a Known Issue?
Yes. The Subnautica 2 community has widely reported:
- power relays not connecting
- turbines refusing to transfer power
- Metal Farms losing power
- habitat desync issues
- relay chains breaking after reloads
Since the game is still in Early Access, these bugs are likely tied to the current base-building and power-grid systems.
For now, rebuilding everything through a habitat module is the most reliable solution.
FAQ
Why is my power transmitter not working in Subnautica 2?
The current Early Access build has a known power-grid bug where transmitters, turbines, and Metal Farms sometimes fail to connect properly unless they are attached through the same habitat network.
How do you connect a Hydroelectric Turbine in Subnautica 2?
The safest method is:
- connect the turbine to a habitat module first
- then connect all powered structures to the same base network
Direct turbine-to-farm connections often fail.
Why is my Metal Farm not getting power?
Your Metal Farm may still be linked to an older base internally, or the power transmitter chain may have bugged out after reloading the game.
Are power transmitters bugged in Subnautica 2?
Yes. Many players are currently experiencing relay connection bugs, failed power transfers, and broken turbine networks in Early Access.
Can you fix the Subnautica 2 power grid bug permanently?
Right now there is no guaranteed permanent fix, but rebuilding the network through a fresh habitat module is the most consistent workaround available.
