Powering the Naquada generators?

[Gregatrongate1984]

In the Fifth race Jack hooked up the Naquadah bulb to a large circuit box so I concluded that the power didn't come from the bulb but from the electrical grid used by the sgc. I surmised that the bulb only allowed the gate to draw ten times the power it usually does not provide the power.

In Atlantis they talk about power sources to jump start the gate rather then power it.
