# Power Supply

[**Motherships** ](/assets/structures/mothership.md)have a **Power Supply capacity** stat that serves as a **supply cap for Structures.**

Constructing and controlling a [Structure ](/assets/structures.md)requires a certain amount of Power. Different types of Units may have different Power requirements. Also, as Structures level up they will generally require more Power.

A Structure cannot be constructed if the Mothership constructing it does not have enough Power Supply left to control it.

When a Structure is destroyed, it stops drawing Power from the Mothership.

Leveling Up a Mothership will increase its Power Supply capacity.
