Advanced Geothermal Powerplant
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 more costly than Wind Turbines and Solar Collectors, but provide a good energy bonus when completed.
