AEP was incorporated under the laws of the State of New York in 1906 and reorganized
in 1925. It is a registered public utility holding company under PUHCA that owns,
directly or indirectly, all of the outstanding common stock of its public utility
subsidiaries and varying percentages of other subsidiaries.
The service areas of AEP's public utility subsidiaries cover portions of the
states of Arkansas, Indiana, Kentucky, Louisiana, Michigan, Ohio, Oklahoma,
Tennessee, Texas, Virginia and West Virginia. The generating and transmission
facilities of AEP's public utility subsidiaries are interconnected, and their
operations are coordinated, as a single integrated electric utility system.
Transmission networks are interconnected with extensive distribution facilities
in the territories served. The public utility subsidiaries of AEP, which do
business as "American Electric Power," have traditionally provided
electric service, consisting of generation, transmission and distribution, on
an integrated basis to their retail customers. Restructuring legislation in
Michigan, Ohio, Texas and Virginia has caused or will cause AEP public utility
subsidiaries in those states to unbundle previously integrated regulated rates
for their retail customers.
The AEP System is an integrated electric utility system and, as a result, the
member companies of the AEP System have contractual, financial and other business
relationships with the other member companies, such as participation in the
AEP System savings and retirement plans and tax returns, sales of electricity
and transportation and handling of fuel. The member companies of the AEP System
also obtain certain accounting, administrative, information systems, engineering,
financial, legal, maintenance and other services at cost from a common provider,
AEPSC.
