You can start placing new relay towers connecting from your original factory in the Core AIC Area all the way to the Originium BPPC Building to supply power to the Energy Nexus.

The shortest route is through the large building just south of the Core AIC Area, although you can also place relay towers through the main road if you wish to power the other surrounding areas.
