INTRODUCTION
This report consists of a review of the electrical power
facilities "., aimed at determining the 25X1 A
changes re red to make these facilities adequate for the purpose
intended. There are two main parts., one for
25X1 A for , followed by a summary of recommendations anand d ane 25X1 A
estimate of cost.
Summary of report is on page 4 of Section titled 25X1A
ESTIMATE OF THE SITUATION
25X1A
PROBLEM: Revise present power system to provide adequate
commercial power for all needs, and an emergency source for essential
needs.
FACTS BEARING ON THE PROBLEM:
a. Present service consists of a 2400-volt line, connected
to the power company's single-phase line at the eastern edge of
the Government property and coming in to a 50 KVA transformer
which, in turn, is connected by a short 240/120-volt line to the
electrical load center housed in an adjacent building. See
Drawing 'W.
b- Power company owns above lines and transformer.
c. Emergency power is presently available from a 75 KVA
single-phase diesel-driven generator, located at the load center.
d. Total connected load is 250 KVA. Present 25X1A
maximum demand is approximately 70 KVA, which is approached at
least once a day. Average load, based upon observations, is
55 KVA durinr; a working day*,
e. Power company is willing to convert the present 50 KVA
single-phase service to a 1122 KVA, three-phase service, utilizing
the present access route. Power will be metered,at low voltage.
f. Power company is also willing to furnish three-phase
service at any suitable point along the east and south sides of
the Government reservation. In this case., the Government would
buy power at high voltage at the property line.

g. All power is now metered at low voltage in the
25X1 A - load center.
25X1A

25X1A
h. Present load center is connected for single-phase
distribution.
i. Majority of local feeders are underground. Feeder
to residences, dispensary, warehouse and motor pool are
overhead.
J. In the event of an emergency necessitating; operation
on a full-use basis, the average electrical
load would increase by a large amount, roughly
estimated to be at least triple, and possibly more.
k. Feeder is operating near
full load and running warm.
1. A survey of the reservation indicates that the most
desirable location for the emergency generating station, is
25X1A in the open area between This is con-
sidered to be the optimum with respect to noise of operation
and proximity to the existing load center. See Drawing
m. Serious consideration is being given to the construction
of a Records Center Building. This would be an additional load
of approximately 100 KVA, based upon complete air conditioning,
elevator and fluorescent lighting with some supplementary
incandescent lighting.
EOLICIES PERTAINING TO THE PROBLEM:
25X1A
25X1A
a. The facilities at this -shall be ready for
full-scale operation in event of a national emergency, involving
"round-the-clock" support of existing facilities and additional
temporary facilities.
b. Electrical facilities must permit reasonable expansion
at any time with a minimum of basic change in installed facilities
and a minimum of additional expense.
c. operating and maintenance personnel shall be
as few as possible.
DISCUSSION: The problem divides into three main considerations:
a. Determine, as nearly as possible, the various loads
obtained under full-scale, around-the-clock emergency conditions,
in order to arrive at suitable transformer and emergency generator
capacities.
Approved For Release 2000/08/17 : ClA.8-04720A000100040036-6

- 3 - CONFIDENTIAL
'.). Determine optimum route for the power line, and
whether it should be high or low voltage.
c. Resolve corollary problems.
Regarding the various loads,, there is rather little factual
information or experience data available and it becomes necessary,
to make certain assumptions.
Reference is made to Tab 1. Accepted demand factors have
been applied to each building in accordance with the type and
purpose of the connected load. Based upon these computations, a
maximum demand has been determined for each building, and an
25X1 A apparent total maximum demand This, apparent
maximum demand has been reduced by a diversity factor, since the
provability is rather remote that the maximum demands for all
buildings will occur at the same time. The conditions imposed
by a full-use, around-the-clock, situation can be severe and it is
felt that the diversity factor should not be less than 0.90. This
results in a computed maximum demand, for the whole station, of
195.91 KVA for she present connected load, or. a - demand 25X1A
factor of 0.77.
In addition to the present connected load,, certain demands
will be created by temporary quavers and facilities which will
be constructed in the event of a national emergency. The extent
of these demands can only be approximated. However, it is con-
sidered that the amount and demand factor would not be such as to
cause a sustained station load in excess of the 225 KVA transformer
capacity.
25X1A
In view of the foregoing discussion, the estimated total maxiniun
demand under emergency conditions is 195.91 KVA. The nearest standard,
size transformer bank is 225 KVA, consisting of three (3) 755 KVA
transformers. it is recommended that such capacity be installed.
Regardir the new Records Center Building, this is a substantial
load which should be served independently at high-line voltage, 2400-
volts, with a separate transformer bank located at the buil-ling. The
possible advent of such a building does not have any effect on
determining the size of transformer bank needed for the present
load and can be disregarded at this time.
It is contemplated that three diesel-driven generators are
required to provide standby power. The available generators are
skid-mounted, General Abtors 75 KVA, 80% Power Factor machines,
self-contained, except for fuel supply. One would be sufficient

to carry the Office and Dispensary and Guard Stations, with the
remainder entirely off except for a few small
lights. An additional generator would permit all refrigeration
and heating and a limited use of lights and electric cooking. A
third generator would provide relief for the first two on a
rotational basis. At present, only two generators are available
for installation . It is recommended that a power-
house be constructed to accommodate three generators and that the
two available machines be installed and a third machine be procured
for later installation.
Regarding an optimum route for the power line (incoming),
three possibilities have been considered and one appears as an
optimum solution. Briefly, these are:
Route A - utilize route of existing pole line.
Route B - install underground cable as indicated on
Drawing "e.
Route C- construct new pole line along route indicated
_
on Drawing 'A".
25X1A
25X1A
25X1A
Analysis of Route A:
Route A has been ruled out because, as can be seen from
Drawing "A", the present single-phase power line is uncomfortably
close to the water tank passing between these
structures with a minimum side clearance of ten (10) feet,
which is not a desirable condition. This route places the
power line in close proximity with several radio antennas
mounted on thereby creating an interference
problem. Also, the low voltage feeder from the transformers
would pass under the roadway, necessitating expensive trenchir;.
The maximLmi transformer capacity which the power company is
willing to install is 112 KVA, based upon current load conditions.
The power company does not choose to recognize the need- for pro-
viding sufficient transformer capacity as standby for aLll-out,
full-use, operation. Further, they will not change the pole line
from single to three-phase operation unless they also own the
transformer bank to be served. This leaves the Government with
very little option, since the - load under emergency
conditions would exceed 112 KVA by a considerable margin. As
an alternative, the possibility of purchasing Route A and makin?
necessary alterations thereto has been considered. However, the
inherent faults of this route and the cost of the alterations
combine to make this alternative appear impractical and not
productive of the desired results.

- 5 - -,U VFIDENT tt,
In view of the foregoing discussion, Route A has
been eliminated from consideration.
Analysis of Route B:
25X1A
Route B has been ruled out because of cost and certain
inherent faults.
Because of crowded conditions in the vicinity of the
-load center, it would be necessary to locate the
transformers at the property line, as shown on Drawing "A".
Thus, the underground line would operate at 120208-volts,
requiring multiple cables in order to carry a load in the
neighborhood of 800 amperes. This type of construction is
quite expensive, and the amount of clearing and trenching
would make the whole cost of the incoming line prohibitive.
In addition to the high cost, Route B has certain
features of inflexibility. With this route, the emer(;ency
power change-over switch necessarily would be located at
the load center instead of the diesel powerhouse, so that
the procedure of changing over to diesel operation would
be awkward and time-consuming. Also, the metering point for
Route'B is screened from the rest of the reservation by under-
growth, trees and buildings, so that the constructing of the
200-volt line to serve the new Records Center Building would
be impractical and expensive.
In view of the foregoing discussion, Route B has been
eliminated from consideration.
Analysis of Route C:
Route C appears to overeome the disadvantages of A and B
and to have some advantages of its own. It would be over open
ground at a comfortable distance from buildings and antennas
and would run through a "draw" where no future building con-
struction is likely. This route would run directly to the
proposed powerhouse and transformer station so that there need
be only one short low voltage feeder running to the load center.
Route C has no clearing problems and no roadways to trench
across. The line would be overhead and could be tapped at any
point to provide service for the Records Center Building.
In view of the foregoing advantages, it is recommended
that Route C be employed.

-;-
Regardless of the route employed, however, there are
certain corollary problems arising in connection with any steps
25X1A taken to correct the power situation . As stated
earlier in this report, the power company does not choose to
recognize the need for providing sufficient transformer capacity
at their expense as standby for all-out, full-use, operation of
25X1A . Further, they do not wish, as a matter of policy,
to have any of their lines or transformers on Government property.
As a result, in order to have adequate incoming power line and
25X1A transformer capacity at , they must be Government-owned,
with power being metered at the property line.
Ownership of the facilities involves a maintenance program
to insure proper functioning of the service at all times. This
is not a serious problem but one that nevertheless must be
resolved. Poles, lines, transformers, etc., must be inspected
at intervals and necessary corrective action taken. There are
two ways in which this may be accomplished, namely, by contract
or by Government personnel.
25X1A
25X1A
25X1A6d
25X1A
25X1A
The preferable method is by Government personnel, since this
assures prompt service and ood. security. One man added to the
present force, with such occasional assistance as may be required,
could conduct routine maintenance of power facilities at both
and also be available for other kindred
duties. It is strongly recommended that, except for major repair
maintenance group. A grade of GS-9 should be assigned.
work, the maintenance of electric service facilities 25X1A
be discharged by a qualified man added to the 25X1 A
The alternate method of providing routine maintenance on a
contract basis is not feasible. In addition to the service and
security considerations, there is no concern in which is
considered qualified in high-line and transformer work. A
Washington concern seems the most likely in this case.
CONCLUSION
It is recommended that facilities for 225 KVA of public utility
and emergency standby electric power service be installed
utilizing Route ' C" as shown on Drawing "A". Estimated cost of
this work is $lo,995.OO as shown in TAB 2.
It is further recommended that one GS-9 maintenance man be
added to the station complement, for electrical maintenance at

PROBLEM: Revise present power distribution system to
provide emergency power to all points of usage.
25X1A
25X1A
FACTS BEARING ON TAE, PROBLEM:
a. Emergency power for the and quarters 25X1 A6d
area only is presently available from a 31.. A,three-phase
diesel-driven generator, located in Building 11 as shown on
Drawing "B".
b. Total connected load on station is h?8 KVA. Present
maximum demand is 11.3 KVA. Average load, based upon observa-
tions, is 65 KVA*
c. In the event of an 'emergency necessitating operation
on a full-use basis, the average electrical
- would increase by a large amount, roughly
25X1A
estimated to be at least triple.
d. Present commercial service consists of a 12,500/7200
volt line, connected to the power company's three-phase line
at the northern edge of the Government property and feeding
six (3) widely separated points of usage, as shown on Drawing '`H".
All power is now metered at low voltage at six (6) different
points on the station.
e. Approximately half of above line is jointly occupied
by power line and telephone cable. Telephone company owns all
poles on which their cable is carried. Power company owns all
poles which are occupied only by power lines, and all power
lines and. equipment,
f. Power and telephone companies are willing to sell
their poles, power lines and power line equipment. Power
would then be metered at high voltage at the property line.

DISCUSSION: The problem divides into two main considerations:
a. Review of--the connected load to determine the
adequacy of the presently installed emergency generator*
b. Determine optimum distribution system for supplying
the entire station from the emergency generator.
25X1A
25X1A
25X1A
Review of Connected Load:
Regarding the adequacy of the existing generator, this
machine should be sufficient to supply on a full-use 25X1 A
basis. Applying the same demand factor as was developed for
, the maximum demand appears to be 77% of 468 KVA, or
3b0 KVA. By judicious use of lights, and electrical devices,
the total - load can be held at or near the generator capacity
of 360 KVA. Additional economy measures in the use of communications
and mess hall equipment, without interfering with operations, should
*"urther reduce the load when operating on the emergency generator.
The alternative is to install an additional generator, which, at the
rate of $125,000.O0 each, is out of proportion to the small advantage
;wined. It is recommended that no additional generating capacity
be contemplated unless en appreciable addition is made to present
facilities.
Determination of optimum 2lethod of Distribution:
In order to transmit power from the emergency generator to
all points of usage, it is necessary to modify tue present distribu-
tion system or build such a system.
The obvious solution is to utilize the existing lines on the
25X1 A since they can be energized by the generator through the
adjacent 225 KVA transformer bank. Thus, the tower, sewage
plant, laboratory building and pumping station would receive high
voltage service through the inuividual local transformer banks
25X1A6d while the and quarters area would receive low voltage
service directly from the generator as now provided. This method
is electrically sound but it involves some other considerations.
The above method involves the use of a portion of the power
company's high voltage lines. Such use is not permitted bye the
25X1 A power company wince there would be a "bacl'eed" into their lines
which serve the area adjacent . To overcome this
situation, it is necessary that the Government own the lines which
are on Government property and that s, main cut-off device be installed,
at the point of service at the property line. When the cut-off
device is open., the Government-owned lines may be energizer! from
the emergency generator without danger of "back-feed" as described
above. The expense of installing this arrangement is not ineon-
F3.derg ble but is offset by an advantage of metering at only one point.

Approved For Release 2000/08/17 : G'DP78-04720A000100040036-6
A considerable saving is realized by metering at one point
instead of the present six. The power company has shown that
a saving of over $3,000.00 per year can be realized in this
way, , based upon 1953 actual usage. This does
not include the new laboratory building, which will increase the
above saving. It can be seen readily that this amount over a
period of a few years will amortize in a short time the estimated
:02+,305.97 required to install the emergency distribution system.
It is recommended that the emergency distribution system
discussed above be installed.
CONCLUSION
25X1A
. a. Present 312 KVA generator be
considered adequate for all essential needs, with the
- operating on a full use basis.
b. Power and telephone lines be purchased and
necessary switching equipment be purchased and installed
to provide for emergency distribution of power from the
generator to all usage points and to provide for a single
metering point.
The estimated cost is $21+,305.97 as shown in TAB 3.

and a like amount f'rcagn emergency generators. Estimated
cost - $16,995.00.
The electrical distribution system at is 25X1A
inadequate. The amounts of available commercial and emergency
power are sufficient. However,, certain changes are necessary
to achieve complete emergency coverage to all points. Estimated
cost - $24j,305-97-
Total estimated cost of above work - $1+1,300.97.
25X1A One GS-9 maintenance repairman is necessary and should
be added to the complement " to take 25X1 A
