necessary to examine the larger intercon~ected system that would provide a
potential market for the power and energy.,

The electric power industry has di~ided the United States into nine
electric reliability council regions endompassing the United States and a
portion of Canada. The nine council regi6ns are shown in Figure II-5. These
reliability councils were formed as a re$ult of great national concern over
the ability of interconnected bulk power systems to operate reliably without
widespread failures in electric service.

The Western Systems Coordinating Coup.cil region, which encompasses the
western United States, is divided into: four subregions, or general load
areas. These reflect concentrations Qf natural resources and economic
activity and the attendant growth of pppulation and industry in certain
geographical areas. The Western Systems Coordinating Council region and its
subdivisions are shown on Figure 11-6.

The greater interconnected system representing the potential market for
power and energy production from a Cache laPoudre Project is the Rocky
Mountain Power Area of the Western Systems Coordinating Council region. The
State of Colorado lies within the Rocky Mountain Power Area.

The three utilities that most likely:would be impacted by hydroelectric
production from a Cache la poudre Project;! Public Service Company of Colorado,
Tr'i-State Generation and Transmission A$Sociation, and Platte River Power
Authority are major member utilities of the Rocky Mountain Power Area.

Under the reliability council arrangements, var+ous utilities have joined
together into operating pools for coordin~ted planning and operation to more
efficiently match loads and resources. iThe Inland Power Pool is a formal
operating pool with the principal objecti~e of sharing reserve capacity among
its members. Members of the Inland Power fool operate electric generation and
transmission systems in Arizona, Colorado, New Mexico, Wyoming, and portions
of Utah and Nebraska. The systems are i~terconnected by 345 kV, 230 kV, and
115 kV transmission lines. '

Output from a Cache'la Poudre Project would most likely be integrated into
the Inland Power Pool. The three utiliti:es mentioned above that most likely
would be impacted by the hydroelectric pro~uction of a Cache la Poudre project
are all members of the Inland Power Pool. '
