In this guide, you will come to know how to make a thermal plant farm and connect it to your base in Subnautica.
To start, you will need to have a base, though it doesn’t matter where you built your base since the power transmitters can have a near-infinite range. But you will also need the power transmitter blueprint unlocked, and you have to use it to connect the thermal plants to your base.
The heat zone you will need to use is the area in the jellyshroom caves, and you have to start from the coral tube that sticks up out of the water to get there. Head about 2-3 bumps to the right of southeast until you reach a hole in the ground that will lead you to the jellyshroom caves.
To get down to this area, you will need a sea moth with an Mk1-Mk2 Depth module, and it is recommended to have the perimeter defence as there are crab snakes in the cave. You will also need gold, aerogel, titanium, magnetite, and a Habitat Builder.
Also, you don’t have to use the heat zone to make your thermal plant farm since there are many other heat zones.
Once you are in the jellyshroom caves, you will need to head about just in between west and northwest until you reach a sort of entrance. It will lead you to another large opening.
It is the entrance that you are looking for. Once you reach this opening and an area that looks like this, you have to head west or bump to the right of the west until you see steam coming up from the ground in which you’ll have reached the heat zone.
After reaching the heat zone, you have to begin placing your thermal plants. You can build a foundation above while still close to the heat zone and place the thermal plants on the foundation, and the heat will still reach them.
When getting this close to the heat zones, having a reinforced dive suit on is recommended as it will reduce the damage you take from the heat/fire. It is also recommended to bring first aid kits since if you are building this close to a heat zone, you’ll likely take some damage.
Also, keep in mind that you can see a number/temperature displayed on the little pad on the thermal plants, and the higher the number is, the more power it will generate. So you typically want it to be at least 71 C to generate a decent amount of power, depending on how big your base will be and how much energy you are going to drain.
Once you’ve made your thermal plant farm, you have to connect the thermal plants using a power transmitter, and then you have to build the power Transmitters leading back to your base starting from your base as when you connect them, Make sure you build transmitters from your farm to your base not from your base to your farm.
When you see a blue beam/line going into your base from the power transmitter, your base should be connected to your thermal plant farm. In the actual game, when you go into your base, you should see the word power at the top of your screen and some numbers that show how much power you have. If it worked, then your base should be getting power.
