distribution substation contains other necessary and related
electrical and structural components, including pull-off
structures, switches, bus work, feeders, voltage regulators,
equipment contained within a “relay vault” (a concrete block
enclosure for electrical equipment), wire, cable, control panels,
fencing, concrete, and steel. Regulations require that a chain
link fence enclose distribution and transmission substations.
FPL viewed each distribution and transmission substation as a
single facility.88
FPL planned a distribution substation typically 5 years in
advance. The planning process included an analysis of the number
of transformers required. Substations are built according to
more than 100 structural and electrical plans. The plans
graphically illustrate the location of the transformers and
feeder positions. To build a substation, FPL was required to
obtain permits from local, State, and sometimes Federal agencies.
To allocate funds to the project, FPL prepared a budget item
the year before a substation was constructed. After the budget
item received approval, an engineer prepared an expenditure
requisition to authorize the payment for the project against the
budget item. Once the budget item and the expenditure
requisition received approval, FPL prepared detailed drawings for
88 Ken Veronee, an employee of FPL, testified that each
distribution and transmission substation was a self-contained
unit.
