The new sub would have 2x 66-34.5kV 150 MVA banks. This is just to feed the furnace. We are trying to get the short circuit capacity up. It would also have 2x 28 MVA banks for our 12kV auxiliary feeders.
I was under the impression that the emeron 66kv was just for your Aux and the furnace was fed from a 220kv from the north. I'm not a distribution guy, strictly generation.
Right now, we have 2x 66kV circuits feeding us. 1 is from the same 220/66 bank at Etiwanda that Grapeland is also on. That feeds everything here but the furnace. The other 66 kV feeder we have comes from a dedicated 280 MVA 220/66 bank at Etiwanda. That one feeds Ameron sub which feeds the furnace.
Both of our 66kV lines run just east of Grapeland.
Even though the line for the furnace is its only load, it is not enough. They need to run parallel conductors on the 66 line and install 2x 150 MVA transformers for the 66/34.5 to get the SC capacity up. Right now we have about 400-500 MVA short circuit available. We need about a 1500 MVA SC rating.
I want to see if I can break the coupling on your generator
