This report presents the results of the Forty-Seventh
Semi-Annual Electric Power Survey made as of
April 1, 1970, by the Electric Power Survey Com-
mittee of the Edison Electric Institute in cooperation
with the representatives of the electric power systems
or power areas throughout the contiguous United
States and the nation's principal manufacturers of
heavy electric power equipment. The survey also in-
cludes the State of Hawaii and the Commonwealth
of Puerto Rico.

The survey covers practically the entire electric
utility industry of the country, including investor-
owned systems and those of governmental agencies
-Federal and non-Federal- and also rural electric
cooperatives. The only omissions are comparatively
small systems which have little effect upon the trends
forecast and which collectively represent less than
3 percent of the capability of the total industry.
also includes those industrial power

survey

installations whose operations are coordinated with
the utility systems with which they are intercon-
nected and which thereby contribute to the public
supply. It does not include any isolated industrial or
institutional power installations.

Survey results pertaining to power system capabil-
ities, loads, gross margins, and energy outputs as
reported are presented for each of the eight power
supply regions of the United States, as defined by
the Federal Power Commission and shown by the
map in Fig. 1. They are based on the specific cover-
age of the survey. Summations of these regional data
are presented and referred to as "Survey Totals for
the Eight Regions."

Also presented are figures which represent the
Total Electric Utility Industry of the contiguous
United States, including those industrial installa-
tions contributing to the public supply. These values
are based on the survey totals for the eight regions

but incorporate upward adjustments to compensate
for the minor omissions in survey coverage pre-
viously mentioned. No adjustments have been made
to the survey totals for the individual regions.

Survey data for the State of Hawaii and for the
Commonwealth of Puerto Rico are presented sep-
arately.

Data in this survey report pertaining to the manu-
facture, in the United States, of heavy power equip
ment for all classes of customers represent substan-
tially all such manufacture in this country.

Information concerning electric generating units
ordered abroad for public utility service in the
United States is furnished by representatives of
foreign manufacturers as well as by the domestic
power systems which have ordered them.

Definitions of the terms used in this report, to-
gether with information concerning methods of sum-
marizing the data, are given in Appendix II, page 51.

Summer peak capabilities, peak loads, and gross
margins as recorded for the years 1968 and 1969,
and as now forecast for the years 1970 through 1975
on the basis of median hydro conditions, are shown
in Table 1, page 6. Similar information for Decem-
ber is shown in Table II, page 10.

Fig. 2, page 5, is a graphic presentation of the
summer situation for the total electric utility industry
of the contiguous United States during the period
1953 through 1969. The chart also includes the
present forecasts for the summer of the years 1970
through 1975 based on median hydro conditions.

Fig. 4, pages 12 and 13, gives a graphic presenta-
tion of the regional summer and December capa-
bilities, peak loads, and gross margins based upon
the specific coverage of the survey in each region.

Forecasts based on assumed adverse hydro condi-
tions are given in Table 1-A, page 7, for summer of
the years 1970 through 1975. Table II-A, page 11,
gives the December forecasts for the years 1970
through 1975 based on assumed adverse hydro
conditions.

SUMMER CAPABILITIES

The regional summer capability forecasts shown
by this survey show slight variations, mainly in-
creases, from the values indicated in the previous
survey, but for the eight regions taken together there
are only minor differences for the years 1970 through
1974. For 1975, shown in these surveys for the first
time, the summer capability of the total industry is
forecast at 510.6 million kw. This represents an
average annual increase of 9.3 percent for the six-
year period from the summer of 1969.

SUMMER PEAK LOADS

The summer peak load for the total electric utility
industry, which was 257.7 million kilowatts in 1969,
is forecast to reach 281.8 million kilowatts in 1970,
an increase of 9.4 percent. For the summer of 1975,
the forecast is 418.0 million kilowatts. This is an
average annual increase of 8.4 percent for the six-
year period from the summer of 1969.

The average annual increase in the December peak load for the same six-year period is also 8.4 percent.
