The main power to the skyway station is supplied to substations located at which locations?

• A. Central Substation
• B. All three locations: Central Substation, San Marco Substation, and O&M Center
• C. O&M Center
• D. San Marco Substation

Answer: (B)

Redundancy in power distribution for critical facilities. The skyway station is fed from multiple substations—Central Substation, San Marco Substation, and the O&M Center—so power comes from all three sources. This arrangement provides reliability: if one feeder or substation trips or is being serviced, the others can carry the load and keep the skyway station powered. It also allows better load sharing and minimizes voltage drop, which is important for maintaining operation of life-safety and critical systems. Feeding from a single substation would increase the risk of a loss of power during a failure or maintenance, whereas distributing power across three locations keeps the station up and running.
