The Advanced Geothermal Powerplant produces energy using steam. Geothermal energy production is a constant +1250, however, it can only be built on top of steam vents on each map.

Seize control of nearby steam vents to take advantage of reliable energy.

They’re often the most metal efficient source of energy on a map. Being a hazardous Geothermal Powerplant, they explode in a very large and strong explosion.
