to provide power to Sand Island facilities as follows:

Feeders in underground conduit are run to the Powerhouse, the Signal Building,
the Transmitter Building and the Baker-Nunn Camera Station. A 450 kva substation is located in the Powerhouse and is equipped with switchgear to permit
the cutoff of the Sand Island power demand in the event of a transmission failure
in any leg of the submarine cable loop. The existing generators in the Coast
Guard Powerhouse were placed on standby. (Completed in December 1968.)
