POWERHOUSE 1

• Powerhouse 1:

• 3 Turbine Generators, output of 105.3 MW of power

• Switchyard 1:

• Voltages of 4.16KV, 13.8KV, 34.5KV, 69KV, 115KV and 161KV.

• 5 Transmission Lines and a 115KV tie line to Switchyard 2.

PH1 15KV SWITCHGEAR

• Manufactured by Westinghouse Electric and in service since late 1940s.

• Configured in a main and transfer bus configuration, connected to Units 1-3 by segregated bus.

• Contains generator breakers for Units 1 – 3 and feeds the step-up transformers and Station

Service transformer A located in the switchyard.

SWITCHGEAR CONDITION RISKS

• Medium voltage switchgear is original equipment with increasing reliability and operational risks due to obsolete parts and age and does not meet modern safety standards for working clearances or arc flash mitigations.

15KV REACTOR & KV7A 15KV FEED

• 15KV Shunt Reactor, no longer in service.

• Transformer KV7A is a 3-winding transformer, its 15KV feed is comprised of paper insulated lead covered cables, 3” IPS bus, and 1250 kcmil cables.
