MULTIGROUNDED NEUTRAL DISTRIBUTION SYSTEM

[mtnelect]

The bottom line is, PG&E runs 80% of this state, power wise. They set the tone.

Most of their old stuff is delta but it has been declared by them that any new systems will be MGN 21 kV

All of the surrounding pocos to the north and east already run MGN by default, Pacificorp and NV Energy

They have been building MGN 21 kV systems since the 1960s and they are not going to stop now just because you said so.

They have been sued and lost a dozen times, high profile, going back decades, and they just keep going the same as ever.

Great information ...

FWIW since I've been looking I don't believe I've seen any primary MGN on PG&E. Everything is two bushing transformers with no visible connection between primary and secondary neutral.

Areas I can think of off the top of my head are:

1. Plumas Lake area south of Marysville/Yuba City (new)
2. El Dorado Hills area (newish I think)
3. Penn Valley/Rough and Ready area (this area has been 21 kv for over 50 years now)

There may be others but those are the ones I know.
