This Subnautica 2 Guide shows where to find the Thermal Plant fragments and how to connect it, so it can start supplying energy. The Thermal Plant is one of the best ways to keep your base powered. This works in hot areas of Subnautica 2. Instead of relying on regular power sources, the Thermal plant converts nearby heat into electricity for your base.
Thermal Plant Guide – Subnautica 2
To begin, start from your lifepod. Then, move toward the southeast or roughly east at around 110 degrees. You need to travel roughly around 491 metres.
Keep moving through the area until you arrive at the spot. The good thing about this location is that both Thermal Plant fragments can be found close together. This helps you with your exploration to find the second fragment to unlock the blueprint.

Once you find the fragments, scan both of them to unlock the Thermal Plant blueprint. To make it, you will need 3 Titanium, 3 Copper, and 3 Gold.
How the Thermal Plant Works
The Thermal Plant generates electricity by using heat from the environment around it. Because of this, it mainly works in hotter regions where thermal energy is available. It is not designed for normal areas with low temperatures.
After unlocking the blueprint, the structure must be built outside your base. Before placing it, the game will show how much power the location can generate.
Connecting the Thermal Plant to Your Base
Simply placing the Thermal Plant is not enough to power your base directly. To transfer the electricity, you also need to craft a Power Transmitter.
The Power Transmitter acts like a connection between the Thermal Plant and your base. Once attached properly, the generated energy will begin flowing into your base systems. Adding more Thermal Plants will increase the total amount of electricity your base receives.
The Thermal Plant is a very useful power source. As it continuously converts heat into energy, it can provide the electricity for larger bases when connected properly with Power Transmitters.
