@davidho Well, not necessarily. Here in L.A., when (over a period of many years) they converted to LED street lighting, they took the opportunity to pull out all the old power cables and replaced them with much lower capacity cables suitable for the LEDs. This is not uncommon, since those old cables become problematic over many years, and lower capacity cables are far less expensive.
@lauren @davidho I still think it’s a great idea, though, because even if the cables have been replaced, there must still be infrastructure for them (conduit, etc).
