Powered
Can be set to 'yes' or 'no' and determines whether or not this BuildingType requires power to function. Setting it to 'Yes' will cause all of it's active animations to freeze whenever it is underpowered by default. Setting ActiveAnimPowered=No in the art entry will negate the freezing effect for that animation. Underpowered buildings with Powered=Yes will also stop emitting light if it is a lightpost, and will also not fire it's weapons.
