Advanced Underwater Geothermal Powerplant

The Advanced Underwater Geothermal Powerplant is a Tier 2 Legion sea-economy structure that provides massive, stable energy output from geothermal vents. Designed for late-game naval bases, it supports high-energy demands such as advanced shipyards, experimental units, and heavy weapons.

Best used for: Late-game naval economies, high-energy production chains, fortified sea bases
Avoid: Building without secure control of the geothermal vent or sufficient defenses
