The document summarizes power generation and distribution infrastructure at an industrial facility. It describes: - Two 11kV feeders from the local utility that distribute power to different substations within the facility for reliability. - Four generator units with a total capacity of 29.1MW commissioned between 1997-2017 with different engine/turbine technologies that provide power to areas of the facility. - Costs of power from the local utility versus on-site generation. - Monitoring and control systems used to manage the distributed generation assets and power quality across the network.

1.  KE feeders (11kV) Enter in NRL premises at UTILITY SUBSTATION
 The After KE substation the Feeders are terminated at Substation
no.9 at Lube-2
 For Reliably enhancement and to increase the Synchronization options
they have been distributed to Fuel Refinery Substation no.6A, PG
substations and Substation no.18
 Both Feeders have 1 X 185 (3c) XLPE copper cables
 Load Carrying Capacity of Feeders is 1 x 301 A = 301A
 Feeder 5 and 6 can carry load of 5.1 MW each
