subsidibry own and oTerate an interconnected system of high voltage l

! I transmission lines in Minnesota, Wisconsin, North = Dakota and South I

j Dakota which functions to transport electric power produced in various generating stations or received through interconnections with E t

! other power suppliers. The Applicant's system is part of an inter-

! state high voltage and extra high voltage (ERV) transmission system ,

i j owned by several utilities located in all or portions of. Illinois, i

! Indiana, Missouri, Iowa, Nebraska and Montana and, in 1970,~the province of.Manitnba in Canada. This' interstate system, in turn, is f

1 interconnected with similar systems beyond its Midwest area. . This

total system, ' commonly referred to as a grid system, makes

possible 1

the interstate purchase and sale of electric power between major

]

power systems. These systems assist each other in times of emergency 1 -

by delivering large blocks of power over this- grid. By being able to

{

l rely on the grid system, a company can better cope with unusual 4

i j weather conditions or loss of generating equipment and thus greatly

reduce the likelihood of experiencing power blackouts. The Monticello plant, as well as other generating plants, will contribute electric

power to this interstate system.

l l High volume purchasers of electric power from NSP include the l

market and is an important factor in the national computer industry.

It is the largest national producer of residential heating and air A

/'I conditioning control systems, which are marketed throughout the

, f

! United States, substantial portions of which are manufactured in l

l Minnesota. Its aerospace and defense work is concerned primarily

, with guidance and control systems for space vehicles, missiles, 5 manned aircraft and with weapons. A majority of its aerospace and 4

defense products are manufactured in Minnesota.

1 b. Minnesota Mining & Manufacturing Co., whose corporate headquarters are in St. Paul, Minnesota, and which produces a wide 2 list of products such as pressure-sensitive and gummed tape products,

' abrasives, adhesives, chemical products, graphic systems, etc., which are sold throughout the United States and elsewhere in the world.

provides railway transportation in the western half of the country.

The Monticello plant has been constructed in order to provide l additional electrical generating capability for the NSP syster.1, the need for which arises because of the increasing public demand for electricity.

A critical basis for determination of requirements for ad-ditional generating capability is the forecast .of system maximum demand. For the five-year period from 1964 through 1968, forecasts, l '

based upon median weather conditions, made the year before the j 2 actual occurrence of the system maximum demand range,d from approxi-mately 0.5% to 3% below the weather-corrected system maximum demand i

as it actually occurred. In 1969 the system maximum demand occured on l August 29th at 2873 megawatts (tme) , within about 1/3 of 1% of the ia %

I prior year forecast of 2883 mw.

In 1969, HSP forecast its 1970 system maximum demand to be 3140 mw, including an allowance of 75 mw for continued defense pro-duction activity. A reserve capability must be added to tho system maximum demand to allow for the unscheduled outage of generating

, facilities. By means of probability studies, the members of the Upper Mississippi Valley Power Pool (an association of power sup-pliers in the upper midwest) have determined that a minimum of 12%

reserve capability is necessary, assuming mutual assistance during emergencies being available through interconnections with systems outside the Upper Mississippi Valley Power Pool. This requirement adds 377 mw to the forecast of 3140 mw for a total capacity obliga-tion of 3517 mw in 1970.

Assuming that 460 mw(e) will be available from the Monticello plant, the Upper Mississippi Valley Power Pool is forecasted under

expected weather conditions during the summer of 1970 to have 150 mw(e) of excess capability. NSP expects to be able to purchase the excess capability from other members of the power pool, but this would still leave a deficit of 310 mw(e) at expected wea t.hnr

'] conditions, if the Monticello plant is unavailable. Due t.o factors including delayed completion of other new generating units in the

, 4 midwest area and limitations upon capability of the midwest trans-

\

i \,

mission system 310 mw(c) is not now available for purchase by

4 l

- 5 f Applicant for the summer of 1970 from outside the Upper Mississippi j

valley Power Pool to replace production lost at the Monticello i plant. Occurrence of unusually hot weather could increase the NSP load by 200 my above the forecasts which are based upon expected I

weather conditions. Without power production from the Monticello

, plant during the summer of 1970, the deficit facing NSP and its j

customers approximates 10% of the system maximum demand in normal

~

weather. If unusually hot weather occurs during the summer of 1970, the increased maximum demand would create a system deficit of about 15%, making more likely the need to curtail service to 1

customers if the Monticello plant is not in service.
