   Prolonged outages of
existing generating units might make it necessary for the Companies, depending
upon the demand for electric service upon their system, to use to a greater
extent than otherwise, less efficient and less economic generating units, or
purchased power, and in some cases may require the reduction of load during peak
periods under the Companies’ interruptible programs, all to an extent not
presently determinable.
 
 The Companies’
generating plants and load centers are connected by a transmission system
consisting of elements having various voltage ratings ranging from 23 kV to
500 kV. The Companies’ overhead and underground transmission lines
aggregate 14,978 pole miles.
 
 The Companies’
electric distribution systems include 114,177  miles of overhead pole line
and underground conduit carrying primary, secondary and street lighting
circuits. They own substations with a total installed transformer capacity of
91,117,000 kilovolt-amperes.
 
 The transmission
facilities that are owned and operated by ATSI also interconnect with those of
AEP, DPL, Duquesne, Allegheny, MEC and Penelec. The transmission facilities of
JCP&L, Met-Ed and Penelec are physically interconnected and are operated on
an integrated basis as part of the PJM RTO.
