Phase 2:
Power to the Physical Upgrade site will be provided by PreCorp at 69KV. A 20 MVA
69kV/13.8KV transformer and its ancillary equipment will be installed.
The 13.8KV will power the truck shop and switch gear which will feed the Pug Plant.
From the 13.8KV switch gear there will be a feed to a 13.8KV/4.16KV transformer
which will power the larger motors. Two 2.4MVA 13.8KV/480VAC transformers will
feed motor control centers in the Main Pug Process Building.
The fire water pump starter package will be fed from a 350KVA 13.8KV/480VAC
transformer and will have a diesel-powered backup. The current design does not
include redundancy to feed the plant in case of failure of the main transformer or
power failure. However, the generator used to run the plant during phase 1 will be
available to supply emergency power to critical equipment and utilities. The current
design provides for 60% of available capacity.
