ENERGY SOURCES
AND
FOSSIL FUEL INFORMATION

The adequacy of bulk power supply has always depended upon an
assured supply of primary energy. In the past, increasing thermal energy
requirements for electric generation were met by the availability and
relatively unhindered development of gas, oil, and coal resources, and the
energy industry's prDduction capability which assured an adequate supply
for all sectors of the energy market. For a number Df reaSDns, this
favorable situation no longer exists and it has become important that the
electric utility industry provide estimates of its future primary energy
requirements. Such estimates are needed to establish the total
requirements for coal, Dil and gas tD facilitate regional and national
planning. This section Df the report summarizes infDrmation on actual and
estimated energy sources, thermal energy production, and fossil fuel
requirements as submitted by the DrganizatiDns within the WSCC region.

Table 29 summarizes the prDjected energy lDad for the WSCC
region. Table 7 in the "Loads and Resources" section provides the same
information for the total WSCC region and fDr each of the four major areas
within WSCC. Tables 30 through 38 show actual 1982 and projected
1983-1992 sources of thermal energy production and fossil fuel
requirements for the total WSCC region and for each Df the four majDr
areas.

Figure 10 illustrates the types of energy sources which will
serve the projected electric load of the WSCC region. During the next ten
years, an increasing percentage of the load is projected to be served by
coal, nuclear and geDthermal sources. The tabulated percentages in the
follDwing table allow a direct comparison of the relative shift in the
generation mix under median hydro conditions over the ten-year period.

Figure 11 graphically portrays the estimated quantities of oil,
gas, and coal required to satisfy prDjected electric generation
requirements. The figure indicates that cDal requirements will increase
by 52 percent during the next ten years as the need for coal is projected
to increase frDm 86 milliDn tDns in 1982 to 131 million tDns in 1992.
Oil consumption is projected tD remain relatively constant throughout the
