I surfaced, heart racing, because the reactor pads on my base blinked red and the nearest solar array was buried under shadow. You watch the compass and hope the sea gives you a break; sometimes it feels like the ocean is testing you. I kept one hand on the Scanner and the other on the compass until the first blueprint showed up.
Hydroelectric Turbine blueprint locations in Subnautica 2
Tides and currents leave telltale lines on any shoreline; the same is true under the waves. I’ll walk you through where I found both blueprints so you can stop circling and start building.
Where are the hydroelectric turbine blueprints located?
Think of the lifepod as your origin point. For the first blueprint I moved out to roughly 350 meters, then strafed left or right—keeping the distance constant—until the compass hit 210 degrees. Descend along that bearing and scan the wreckage on the seabed; the blueprint will register once you’re near.
How do I find the second blueprint?
I repeated the same method but pushed my radius to about 400 meters. Again, set your heading to 210 degrees and descend until the Scanner chirps. Both blueprints cluster along the same bearing; they’re close, but you’ll still need to travel to each to register them.
What materials are needed to craft a turbine?
Once both designs are scanned you can fabricate the Hydroelectric Turbine at your Fabricator. You’ll need three Copper, three Titanium, and three Silver per turbine. Grab these from reef nodes, wrecks, and supply caches while you’re making the run.
How to use the Hydroelectric Turbine in Subnautica 2
On shorelines, engineers place turbines where currents concentrate energy. Underwater you’re chasing the same physics: find the drift, set the device where flow is steady, and let the sea do the work.
How do I place and connect the turbine to my base?
Place the turbine in a current or drift field—these are the places that actually spin its internals. Use Power Transmitters to bridge the gap back to your base; multiple transmitters stack and keep losses minimal. I recommend checking the flow visually and watching the turbine’s output meter for consistent power before building a string of transmitters.
You’ll treat the turbine like a remote generator: it’s often off the seabed or tucked into a channel. Think of it as a submerged windmill that trades gusts for currents. If you place one far from your base, chain transmitters; if you place several, stagger them so the currents don’t fight each other.
I used the in-game Compass, Scanner, and Fabricator as my primary tools, and cross-checked images from Moyens I/O and the Steam community guides when I got unsure. Unknown Worlds’ design philosophy rewards patients who map currents the same way a sailor reads ripples.
So—are you going to settle for a single solar string, or will you build a field of turbines and let the sea pay your bills?
