Just follow the heat and you'll eventually find the Alien Thermal Plant nestled in the Inactive Lava Zone. Easy peasy!
To get into the Alien Thermal Plant, you'll need to dive deep into the Inactive Lava Zone! Make sure your Cyclops and Prawn Suit are maxed out, then find the entrance around -1200 meters. Look for a big, spooky building near the lava castles. Might be hot, but hey, you're going to an alien power plant, what did you expect?
