A power cell factory requires some energy in the subsoil. If the satellite report says that energy is available only at some places, you will need a sniffer bot to prospect the subsoil. The marks it lays down provide information about the specifics of its findings; a green cross means that there is an energy deposit at that location beneath the surface, which is indispensable for the construction of a power cell factory or a power station.
If the large power cell at the base of the factory remains red after it has finished construction, that means there is no energy in the subsoil where it was built.
