FINDINGS
OLD HARBOR HYDROELECTRJC
FEASIBILITY REPORT
This feasibility study was perfonned for Alaska Village Electric Corporation to determine
if a hydroplant can be built at Old Harbor which will reduce the cost of electricity as
compared to current diesel generation. The results of the analysis conclude that
hydroelectric power can significantly reduce the cost of generation. The following
sections discuss in detail the data used and the analyses that fonn this conclusion.
Information derived from this work is summarized as follows:
• The first cost of the plant will be $1,341,889.
• The present cost of generating power with the hydro for 30 years is
$2,542,288.
• The present cost of continuing to generate power \Vith diesels for the same
period is $3,687,482.
• The net capacity of the plant will be approximately 330 kW.
• Analysis yields an estimated average power generation for the hydro plant of
2,664,530 kWh per year.
• For the analysis, community power consumption is estimated at 743,594 kWh
per year.
• The hydro energy will need to be augmented by 8,891 kWh of diesel energy.
• The average yearly savings realized when using the hydroplant is $50,699
without considering load grovvth.
The recommended plant will be comprised of a low height diversion, a de-sanding
section, 3,293 feet of High Density Polyethylene Pipe (HDPE), 6,966 feet of 10 gauge
steel pipe, 330 kW turbine and generator, powerhouse, road, and a 7.2/12.4 kV electrical
cable connecting to the existing system. The plant can be constructed using mostly local
labor. The general layout of the system, as well as details of the intake and powerhouse,
are shown in the drawings in Appendix C.
Basic characteristics of the recommended project are provided below:

This report, which was commissioned by Alaska Village Electric Corporation (AVEC),
analyzes the feasibility of hydroelectric power production from an unnamed north-
easterly tributary to the Barling Bay Tributary near Old Harbor, Alaska. The project
location is just north of Old Harbor which is located on the southeast side of Kodiak
Island (See Figure 1 in Appendix C) v.1thin the Kodiak Island Borough. The community
has a population of about 31 0 people.
A previous report by Dowl compared five potential sites in the area for a hydroelectric
plant. They quickly concluded from analysis of maps and quick cost estimating that three
of the sites were not feasible. One of the sites rejected was one of our proposed sites on
the Barling Bay Tributary. Site visits were made to the other two with the Midway Creek
site being selected as the best location for a hydro plant.
This study considered two options on the same tributary. Both options take water from
the Barling Bay Tributary and divert it out of that basin and discharge it into the creek
called Lagoon which runs into the lagoon between the two Old Harbor town sites. The
first option diverts water from both forks of the stream above their confluence at an
elevation near 560 feet. The second option captures only the water from the eastern
drainage of this stream. The first option has a lower head and uses more water. The
second option has a higher head and uses less water and was chosen for it's lower cost.
Dowl' s report includes our first option but not the second. Early on, it was realized that
the low head option would not be as economically feasible as the second option because
JUNE 29, 1995 PAGE2

FEASIBILITY REPORT
two diversions and a significant amount of pipe constructed in canyons was required.
Therefore, the balance of this report discusses the high head option.
The high head option has a longer, smaller diameter penstock with one intake and a
desanding facility. The cost for the pipeline part of this option is more expensive as much
of the pipe has to be high pressure HDPE and steel. The disadvantage of the extra pipe
length and cost is overcome by a less expensive intake and the lack of the long lengths of
pipe in canyons that are needed to surmount the divide between the two drainage basins.
Using lower flow to generate the same power calls for a smaller turbine and smaller
diameter pipeline. The available water shows that there will be stable energy production
from this option.
Figure 1 in appendix C shows the general layout for the proposed plant The intake will
be located on the eastern branch of the Barling Bay stream. The intake is at an elevation
of about 830 feet Water will be diverted through a trash rack into a screener/desander
box and then flow through 3,293 feet of 16" nominal diameter HDPE pipe until the
maximum allowable pressure for the pipe is reached. From this point it will flow through
6,966 feet of 16" nominal diameter steel pipe. The powerhouse is located on the Lagoon
stream at an elevation of about 80 feet. An access trail and electrical transmission route
will extend to the pumphouse road and three phase overhead power line which is located
north of the lagoon. The power connection is at the location of a water infiltration gallery
on the east bank of Lagoon Creek that supplies the community with potable water.
OLD HARBOR ELECTRICAL REQUIREMENTS
Generally, the amount of electricity used by a community is a function of population, cost
of electricity, and earnings of the population. For this study, AVEC has provided a record
of the electricity used by the community over the last two years. In the analysis an
average for each month was used. Interpolation was used to obtain daily usage values.
The following table shows the monthly average amount of electricity used by Old Harbor.
Month Average Power Month Average Power
Needs (kW) Needs (kW)

2 97 8 72
3 92 9 85
4 89 10 89
5 81 l! 94
6 66 12 96
A daily demand curve was also developed to account for the daily fluctuations in power
consumption. These fluctuations take into account the peaks during the day that exceed
the hydro's output although the hydro's average may be greater than the average daily
usage. If the peak electrical needs are greater than the hydro can provide, because of lack
of water or generator capacity, the analysis runs the diesels. This curve is not an actual
representation of the daily changes in the electrical use at Old Harbor but does have the
required elements. It has an average of one and considers peaks near l.5 times the
average. The following is the daily fluctuation curve that was used for Old Harbor.

This study used a community gro\\'th of zero. This is a very conservative assumption as
it is likely the actual situation will be one of some growth. The effects of different
community gro\\th rates and future power requirements are examined in appendix B.
HYDROLOGYANDPOWER
STREAMFLOW
One of the critical factors for a hydroelectric power plant is the availability of water. The
Barling Bay Tributary stream has had a stream gauge installed below the confluences of
the two branches since July 14, 1993. A copy of a preliminary report on the results of the
gauging is included in Appendix D. The following chart shows the estimated
streamflows for a one year period based on this gauging information.
This graph is an estimate of the streamflows on just the eastern drainage basin of the
Barling Bay stream. The flows are 39% percent of those recorded below at the gage. This
is based on the percent of area of the basin above the intake. This eastern basin is about
1.8 mi2 as compared to the total basin size of 4.6 mi 2 at the stream gauge location. This
may not be an accurate assumption. Microclimates and differences in geology and
elevation can affect the streamflows. Without gauging the individual tributary this is the
best method for estimating the amount of water in the east fork. Visual observation of the
quantities of snow in each subbasin indicates they both receive about the same amount of
precipitation. Even if there is a modest difference in water flows between the two forks,
the sensitivity analysis shows that it has little effect on the benefits of the hydroplant.

Nonetheless, given the magnitude of the hydroplant project, a stream gauge should be
installed to verify the quantity of water available.

Date
This recent hydrologic gauging done by the Alaska Department of Natural Resources at
the Barling Bay tributary creek (unnamed creek in their report) has added some reliability
to the estimates for water flows on this creek. Their gauging is estimated to be accurate
for tlow up to 100 cfs (39 cfs in the case of the assumed tlow for the east fork). The
Dowl estimate for this creek showed an average flow of 5. 7 cfs/m? This is consistent
with the Department of Natural Resources predicted value of 6 to 7 cfs/mi 2• However,
actual gauging reveals an average around 12 cfs/mi 2 which nearly doubles the predicted
value. The analysis in this report uses an average flow corresponding to the 12 cfs/mi 2•
The sensitivity analysis in the appendix shows the results if tlows are less than the
average of 12 cfs/mi2
.
AMOIT'IT OF POWER GENERATED
During the \\ri.nter low streamflows will result in the hydro generating less power than
required by the city. Wnen this happens diesel generation will be required to make up the
deficiency.
The following cumulative distribution of hydro output based on streamflows shows how
much of the time the power is greater than or equal to the city's needs. As the chart
shows, on the average the hydro can provide 99% of the city's electrical needs.

EXCESS ENERGY
Energy in excess of the community's traditional needs ~ill be produced by the hydro
plant. This energy can be wasted but it also can be used. No economic credit is given for
use of excess energy. It should not be ignored as it has a value when comparing alternate
designs even though it is difficult to quantify.
The equivalent amount of fuel that can be displaced by the excess hydro power will be
dependent on water flows and the ways in which the excess power is used by Old Harbor.
It is estimated that the equivalent of 147,766 gallons of oil is available on average each
year if all of the energy is used. A realistic assumption is that one quarter of the energy
can be readily put to useful purpose. The basis for this estimate is founded on previous
work with district heating systems.
One of the ways to use excess energy is to employ an inexpensive computer equipped
module which will determine by the changes in electrical frequency whether there is
surplus energy. If there is, a relay is closed which sends the excess to any electric
resistance load. Such a load can be a hot water heater for the school, community center,
or electric heaters for the buildings as welL The excess energy can also be used to light
and heat greenhouses and drive adsorption refrigeration to make ice for fishing or
freezing product. The cost estimate includes a controller for routing excess energy.

FUEL REQUIRED
OLD HARBOR HYDROELECTRIC
FEASIBILITY REPORT
There will be times when there is not sufficient water to supply the demand or when the
hydro plant is down for maintenance reasons. During these times, generation will be
done by the diesel plant. It is estimated that an average of 684 gallons of diesel fuel will
need to be purchased each year to provide this energy. This can vary as water flows vary
from year to year. Some years may not require any makeup fuel at all while other years
will require more than the average.
TYPICAL FEATURES
INTAKE
The intake for this project is a small diversion structure that raises the water high enough
so it will flow into the intake to the pipe that will carry the water to the desander. Figure
4 in Appendix C is a drawing of the proposed intake. 'Ibe intake has to be built strong
enough to withstand spring floods and ice buildup. It also has to be set deep enough into
the stream bed to reduce the flow of water under the diversion so as much water as
possible enters the intake pipe.
The proposed diversion structure is to be constructed of reinforced concrete. It will have
removable stop logs that will enable the water to flush out accumulated rocks and allow
the water to bypass the intake pipe when servicing the desander. Stop Jogs also serve to
control the maximum height of the water during operation. Installing more stop logs
raises the height of the water over the intake.
On the downstream side of the diversion structure will be a concrete pad that dissipates
the energy of excess water falling over the stop log portion of the structure (spillway).
Without this concrete pad the force of the water falling in the stream would eventually
erode away the support out from under the concrete.
Preceding the intake is a trash rack that consists of closely spaced bars (about one half
pipe diameter) that will prevent large objects from entering the intake pipe or blocking it.
DE-SANDING AND SCREENS
The desander is one of the most important components for the operation of the turbine.
Without it, sand and rocks can t1ow down the pipe into the turbine causing excessive
wear and a reduced life. It is very important that the de-sander be built and maintained
properly. Because this is a high head plant and the flow is small, the desander can be
smalL
The desander has a primary settling area for removal of gravel and other large material.
A flush gate that can be opened and closed manually or automatically is located in this
section. \Vhen the flush gate opens, the water flows through the primary settling area
rapidly thereby washing out accumulated gravel. Vlhen the gate is closed, water flows
upward through the screen. This upward flow catches floating leaves which usually are

FEASIBILITY REPORT
found in the fall. The water then continues up until it reaches the operating height in the
desander and flows over the separating wall into the secondary settling basin.
\\'hen the gate in the initial settling portion of the de sander opens, water briefly reverses
its flow down through the screen. This water removes the buildup of leaves and other
floatables and carries it on out through the gate as the primary settler drains.
The secondary settling basin is much larger than the primary basin. This causes the water
to flow slowly through the basin. \\'hen the flow of water is slow, any remaining sand or
grit in the water is able to settle to the bottom. The water then flows through a backup
screen and into the penstock. The backup screen is used in case the first screen fails.
PENSTOCK
The water conveyance system, or penstock, is the single most expense part of a project
such as this.
High Density Polyethylene Pipe (HDPE) pipe will be used in the upper portion of the
penstock. It comes in 40 foot lengths is joined by butt fusing. This pipe has several
advantages. It is flexible, has good flow characteristics, and is easy to install.
Unfortunately it cannot handle high pressures.
Steel pipe will be used for the penstock when the pressure becomes too high for HDPE.
The steel thickness will be 10 gauge (0.1345 inches). Most of the steel pipe can be
lighter, 12 gauge thickness but this thin steel is more susceptible to damage during
handling. For estimating purposes it is assumed that 10 gauge is used throughout.
The steel pipe must have corrosion protection. The outside coating is a special tape
wrapped around a coal tar primer. For this estimate, the inside coating is epoxy. This is
more expensive than a tar based coating but has better hydraulic performance and is more
abrasion resistant.
The steel pipe will be the bell and spigot type with 0-ring seals. These are easy to
assemble and don't require welding. Vv'here gully crossings need to be made, the joint
can be welded after it is assembled. Once welded, it capable of spanning about feet.
Longer spans must use intermediate supports.
Towards the powerhouse where the pressure is too high for 0-ring seals the pipe will be
welded. This will need to be done for about the last several hundred feet. This has the
advantage of forming a continuous piece of pipe that is solidly anchored by friction in the
ground. With this anchorage a large thrust block at the turbine won't be needed. Because
the heat from welding destroys the corrosion protection the weld area will have to be field
coated at each joint.
POWERHOUSE
The powerhouse will house the turbine, generator, load governor and switch gear. A pad
mounted transformer will be located outside the powerhouse. The powerhouse will be
located so the generator floor is above flood stage. The base of the powerhouse will be
JUNE 29, 1995 PAGE8
POLARCONSULT ALASKA, INC. OLD HARBOR HYDROELECTRJC
FEASIBILITY REPORT
concrete. The walls and roof will be wood framing with Tl-11 on the exterior and
greenboard on the interior.
TURBINE
The turbine for this plant will be an
impulse turbine. The turbine will
consist of one or more nozzles that
direct the high pressure water at
buckets positioned around the
wheel. The water hitting the
buckets causes the wheel to spin
turning the generator through the
shaft. Generally, the wheel, nozzles,
and needles are made of stainless
steel which helps to insure a long
life.. The figure at left shows the
configuration of the buckets for an
impulse turbine. The water stream
is directed to the center of the
bucket where the flow divides. This impulse wheel in this picture is connected directly to
a generator.
The nozzles that direct the water at the buckets have needles inside them that can be
extended or retracted to control the amount of water that hits the turbine. These needles
open and shut relatively slowly to prevent water hammer (increased or decreased
pressures) in the pipeline. Between the nozzle and the turbine buckets is a movable
deflector plate. This plate can be placed between the buckets and the nozzle to instantly
prevent water from hitting the turbine. This plate prevents the turbine and generator from
overspeeding when the needles can't close fast enough because of a sudden drop in power
output (breaker tripping for instance).
Using a high head configuration allows the turbine to be smaller than when using a high
flow, low head configuration. The turbine for this plant actually costs less than the 200
kW turbine that was quoted for Chignik Lagoon.
GENERATOR
The proposed generator will produce a minimum of 330 kW at a 0.92 power factor.
Electrically, it will be a three phase, 480 volt unit. It will have static excitation and will
use a Basler or equivalent voltage regulator.
The generator for the turbine will come from the US and will operate at 1 ,200 rpm. It
will have ball bearings and the shaft will be directly connected to the turbine.

GOVERNOR
OLD HARBOR HYDROELECTRIC
FEASIBILITY REPORT
The generator rpm must be controlled to produce sixty cycles. In earlier hydroplants the
speed of the turbine was controlled with a governor that controlled the amount of water
the machine received which, in turn, controlled the speed. There is another way to
control the speed of the machine and that is to add and subtract electrical loads so the
output remains at 60 cycles. This can now be done electronically by a device called a
"load governor". There are a number of load governors operating in Alaska such as at
Burnett Inlet on Alaska Aquaculture's project, Larsen Bay, Ouzinkie, Rainbow Creek, and
more. An electronic load governor can be located anywhere on the three phase electrical
distribution system. It takes power in excess of that being used and shunts it to resistance
heaters. Resistance heaters can be hot water heaters, hydronic heating systems, and
electric air heaters that are located wherever heat is required. Loads are prioritized by the
load governor. As an example, the governor can be programmed to supply excess
electricity first to the school heating system, secondly to the school hot water, and then to
the green house or the city hall.
For a run-of-the-river plant that has no storage, the amount of water that can be used at
any moment can not exceed the amount in the stream. If there is water that the plant is
not receiving but could use then that water is wasted energy. A stream fluctuates as does
the demand for electricity. A 330 kW machine will rarely be used near peak capacity at
Old Harbor. Much of the time there will be excess water that can be used to operate the
hydroplant at an output above the community's needs. The surplus electricity can
produce heat that has value as it can be used to displace fuel and its associated costs.
This provides added value to the plant and also makes it environmentally superior to
burning carbon based fuels.
In addition to the load governor, there is an electronic head level controller that opens or
shuts the turbine needles based on the quantity of water available at the beginning of the
penstock. It does this by reading the water pressure (depth) which in tum is converted to
an electrical signal that is provided to a computer which directs the operation of a
hydraulic pump that drives a cylinder controlling the flow of water to the turbine. If
water is being used at a rate greater than its supply then the needles will close, if the rate
is less than the supply the needles will open until they reach their limits of opening.
SWITCHGEAR
The switch gear will consist of several elements. One item will be the circuit breaker that
will protect the plant if there is over-current. It will also have electronic equipment that
will perform relaying to shut the plant off if there is over or under voltage or frequency.
In addition, transducers can be provided, as was done at Larsen Bay, so it is possible to
monitor the status of the plant from town or anywhere else. In a small plant such as this,
the switch gear and the electronic controls for a load governor can be incorporated within
a single enclosure thus saving space and costs.

TRANSMISSION
OLD HARBOR HYDROELECTRIC
FEASIBILITY REPORT
Different power line designs are possible. The most desirable one, considering aesthetics
and damages, is buried cable. A second design can be bare overhead wire. For this
study, it is assumed that the transmission line will be a buried line adjacent to or under
the access road. This is considered to be more expensive than overhead lines but is used
in the cost estimate because often FERC requires buried power lines.
COSTS
The value of hydropower is based on the least expensive alternative means of providing
the same service. Diesel generation as is done currently is the only feasible alternative to
hydro. Because diesel generation is currently the source of power in Old Harbor, the costs
to operate this system are well known and have been obtained from AVEC.
DIESEL
Diesel generation costs used in this analysis have not been escalated over time with the
exception offuel cost, parts, and lube oil which are tied to the amount of power produced.
The operator salary remains constant over the length of the study as does the amortization
for replacement generators.
FUEL COST
Fuel is the single most expensive component in producing power with diesel generating
units. Total diesel expenditures for 1993 and 1994 are $166,444 and $155,499
respectively (not including depreciation of generators). It is estimated that total plant
average yearly expenditures are approximately $170,265 (including generator
replacement payments). Using a past fuel cost of $1.30 per gallon, $74,359 is estimated
to be used to purchase the 57,200 gallons consumed. This represents almost half of the
yearly cost of operating the diesel electric plant.
The future cost of diesel fuel is uncertain because of the current international situation.
There is no physical shortage of oil in the world nor will there be for some time. Some
analysts believe that the price of oil will go up. A conservative estimate of fuel costs for
this analysis is that they will increase at 1.0% for the next 5 years and at 0.0% thereafter.
Sources for such analysis include the "World Energy Outlook", dated 1990, produced by
the Chevron Corporation. The sensitivity analysis shows in the appendix shows the value
of the hydro plant for different fuel increase scenarios.
EQUIPMENT AND LABOR COST
Equipment and labor costs have been taken from 1993-1994 cost information provided by
AVEC. Appendix F contains the actual reports used to obtain this information. Only
costs under the category "power production" are used in this analysis. It is assumed that
the average of these two years is representative of actual cost associated with the
operation of the power plant.

PAGE 11
POLARCONSULT ALASKA, INC. OLD HARBOR HYDROELECTRIC
FEASIBILITY REPORT
In general, we assume that the materials, lube oil, fuel, and freight cost are directly related
to the amount of power produced. Plant operator, village labor, and travel are assumed to
be fixed at their current level regardless of changes in the amount of power produced.
The exception to this is that we assume that the plant operator cost will drop somewhat
when the hydroplant is able to supply nearly all of the community's power needs.
Parts and lube oil costs are assumed to be a direct function of the amount of power that
the diesel generator produces. The costs for lube oil is assumed to be $0.00221 per
kWh2. Replacement parts generally account for overhaul costs. They also are assumed to
be directly related to the power produced and are $0.05878 per kWh2
. Thus, the cost for
equipment amounts to $0.061.
The cost for the plant operator amounts to $41,171 per year. The plant operator salary
remains constant for increases in diesel production but is lowered to $30,000 per year
when the hydroplant is added. Hydro maintenance salary is assumed to be $10,000 in
addition to the plant operator salary.
The cost for replacing the diesel generators is also included. Replacements are scheduled
for every 6 years when operating just the diesel plant. When using the hydro plant,
replacement of the diesel generators is assumed to occur every 12 years. The cost for
replacing the diesel generators is assumed to be $50,000. This cost is amortized over the
replacement period and is included in the economics.
HYDRO
EQUIPMENT AND LABOR COST
A hydro plant has high initial costs. Therefore, the hydro is more sensitive than other
forms of generation to high interest rates. This analysis assumes that the hydroplant can
be funded through a loan with a basic discount rate of 3.5% above inflation.
Once the plant is built there are no further equipment purchases that need to be made. A
hydroplant such as this is designed to last around 50 years.
Although a diesel electric power plant takes considerably more maintenance than a
hydroelectric plant, the hydro is not maintenance free. This is especially true during the
first year of operation when problems are most likely to occur.
Modem low cost electronic equipment can be installed to monitor the operation of a small
hydroplant. For example, there is an inexpensive device that connects to the telephone
system that will call designated people if the temperature is too high or too low or there is
too much noise. This device also has contacts where a fire detector or other off/on
devices may be connected. One can also call and listen in to the sound level at the plant
which is useful for periodic monitoring. The cost for this device is about $500 and is
included in the cost estimate.

Equipment that facilitates monitoring but is not included in the cost estimate is real time
monitoring devices. Transducers can be installed in the switchgear that will enable the
operator to determine what is happening electrically. This type of system was installed at
Larsen Bay. It may also be possible to install a pair of the new video phones which will
provide an inexpensive way of looking at the power house, intake or other plant features.
Since the operator will be living in tovm and the weather is not always conducive to
inspecting the plant, these remote devices will be able to avoid field inspections that will
save considerable time and effort. After the operator gains experience operating the
plant, fewer observations will be needed. For example, the operator may find from
experience, that after a heavy rain, the screens require cleaning, so the operator will not
bother investigating the screens on a daily basis if the rains have been moderate. This
means that the amount of time spent at the plant will decrease with time.
The diesel back-up can be started and synchronized either manually or automatically
when a power deficiency occurs. Using a load governor simplifies manual startup for
diesel back-up. Since the hydroplant is always producing all of the power possible, up to
330 kW, reading the power output gauges will provide the operator with the infommtion
to determine if there is sufficient water to produce the required (estimated) daily power.
Early in the morning, given the traditional use patterns for the time of year, day of the
week, weather conditions (rain, snow, cold, cloud cover) it will be apparent to the skilled
operator when a diesel generator will need to be added during the day. Also there will be
times while the engine i~ operating when rain rapidly increases the flow and the hydro
begins to generate sufficient power so the diesel is no longer needed. Unless this
condition is observed or there are automatic controls to shut off the diesel, there will be
an occasional waste of diesel fuel. This condition is a more likely event than is the one
where a diesel must be added because of an unforeseen, sudden reduction in flow. This is
because flow reductions occur more gradually than flow increases. Automatic diesel
controllers are not included in the cost estimate.
CONSTRUCTION
Project costs are one of the most important derivatives of an analysis such as this. Their
accuracy along with the demand, estimate of future alternative power generation costs,
costs of money, and quantity of production are the important values that provide the
information to make sound economic judgments.
It is important to assign values to each of these items that will result in a conservative but
realistic result. Too many contingencies have a multiplying effect and can result in
unrealistically high costs. Many construction and operations costs are used in a manner
that will be conservative. These include demand, alternative power generation and fuel
costs, and material and labor estimates.
Project costs are composed of two major elements. One element is material costs. These
costs, if based on good quantities, can be fairly accurate. The second element is labor
cost. This is the variable cost and is more difficult to estimate accurately. As an
example, heavy rain can reduce productivity to as low as 36% of dry conditions.
However, if the work is mostly done during the months of June, July, and August and the
PAGE 13
POLARCONSUL T ALASKA, INC. OLD HARBOR HYDROELECTRJC
FEASIBILITY REPORT
weather is not unusually wet, productivity can be good. Loca1labor costs are also based
on local skills and motivation. If the skill level is high but motivation is low, the
productivity will be low.
A considerable portion of production efficiency depends on the quality of management
and the authority granted to the management to remove unproductive workers. Labor
costs are based on an estimate of the time to do the work assuming a crew and
supervision such as was used on the McRobert's Creek project that Polarconsult
constructed.
Wages are based on information garnered from the City of Old Harbor, force account
work in other communities, and our construction ofMcRobert's Creek Hydro. For wages
the following assumptions are made.
Worker
2 Skilled laborers
2 laborers
I Foreman
Pay per Hour
$15.00
$12.50
$17.50
The average of the above wages is $14.50. This study uses $15.00. Fringes estimated as
follows:
Workers Compensation
Alaska Unemployment
Employer Social Security
Total
8.5%
3.1%
7.65%
19.25%
Average rate per hour calculated is $17.88. $20.00 per hour is used in the estimates.
This is more than rates paid on McRobert's Creek which averaged $10 per hour plus
fringes. Old Harbor is currently paying approximately $12.00 an hour including fringes
for construction of the fire hall.
Itemized material costs are not as variable because their costs are fixed by quotation.
Frequently, quoted prices can be bettered when an order is placed. As a general rule,
these quotations are rounded to higher values. However, substitute items can reduce the
cost.
Freight costs are based on a single barge hauling in the majority of the material during
one trip from Seattle. Because of scheduling, the turbine and generator are assumed to be
shipped separately.
FORCE ACCOUNT
Title 36 is enforced when a contractor or subcontractor performs work on public
construction in Alaska. Title 36 requires that contractors be paid the prevailing wage in
the locality. This prevailing wage is set by the Labor Department's Labor Standards and
Safety Division. For Old Harbor, the average wage plus the fringes will be greater than
30 dollars per hour. The overall cost increase for wages alone would exceed $60,000.
Additionally, contractors have other costs that will further raise this amount.
PAGEI4
POLARCONSULT ALASKA, INC. OLD HARBOR HYDROELECTRIC
FEASIBILITY REPORT
Force account, or turnkey work, is the only practical and cost effective way to construct a
project such as this. Wage rates for Title 36, Little Davis Bacon, are high enough to
make the project uneconomical. Force account optimizes the situation for local
employment and avoids all of the added costs that contracting brings. Some of the added
costs for contracting are the cost to bid, bonding costs, tighter plans and specifications
resulting in more expensive engineering, better record keeping, greater overhead, more
detailed inspection as the contractor must be prevented from cheating, and profit.
Additionally, higher worker's compensation insurance rates are paid due to higher wages.
There is also greater contractor risk and added legal fees, resulting in increased costs and
bids.
The major problem with community force account is management. The manager
generally should not be from the community for the best interest of the project as tough
personnel decisions need to be made. It is better to be stem and bring the project in under
budget and return the money to the workers with a bonus or to the rate payer than it is to
compromise during the execution of the project. A good manager with experience in
force account can strike the balance between sensitivity for local feelings and needs, and
the absolute need to complete the project on or under budget.
To build a quality plant with low cost the philosophy of construction must be different for
small hydro plants as compared to large ones. More of the decisions on routing and
layout must be made in the field during construction. The project must be compatible
with the terrain and not be required to move more rock and earth than is absolutely
necessary, or pour added concrete to match lines drawn on paper as is done on larger
scale projects. This requires a flexible mind and the ability to innovate in order to solve
problems on the spot.
In addition to benefits there are also potential negative aspects of using force account
which follow:
• The primary risk is from cost overruns during construction.
• Another disadvantage is that a project such as this could be conceived as
increasing stress within the community because of the requirement to
complete it on time and on budget. Further, if the community is divided on
the project, there is always a possibility of increased political disagreements
between the anti's and the progressives.
ECONOMICS
The economics of the system are outlined below. The sensitivity analysis in the
Appendix A gives results for different economic assumptions. Loan period and analysis
period is for 30 years.
All of the monetary values in this analysis have been adjusted to present value using the
discount rate. This means that inflation is not taken into account. This gives clearer
resolution of variations in the dollar quantities as it shows all costs in current values
without the distortion of inflation.
An explanation of some of the selected values follows:
JUNE 29, 1995 PAGElS
POLARCONSUL T ALASKA, INC. OLD HARBOR HYDROELECTRIC
FEASIBILITY REPORT
•
•
•
Interest rates: A system was selected that does not use standard interest rates
which include assumed factors for inflation. Everything is reduced to the
opportunity cost of interest which traditionally has been near 3.5%. This
results in costs that are in today's dollars throughout the analysis period. This
helps in achieving a more accurate understanding of the project costs.
Power demand: A conservative figure is 0% growth. More growth favors the
hydro over the diesel.
Loan Period: The loan period is typical for a small hydroplant and again is
conservative as compared to 50 year periods used for governmental projects.
In addition, there are other economic values for the project that have not been quantified.
Some of these values are as follows:
• Retaining money within the community. When oil is purchased most of the
money leaves the community and goes to the transporters, refiners, producers,
and resource owners who increasingly are middle eastern foreigners. The
labor will result in employment for people in the community. Income from
their wages will add new money to the community. The savings from lower
costs for electricity will conserve dollars within the community for other uses.
• People will receive training in construction by doing the work. This training
is valuable as it makes for salable skills, and fosters independence.
COMPARISON WITH MIDWAY CREEK
The Midway Creek feasibility was investigated by Dow] Engineers. It was listed as their
recommended project in their August 1982 Feasibility Study for Alaska Power Authority.
To just use the Dowl report's conclusions to compare to the Barling Bay alternative
would not be appropriate. In order to make an adequate comparison, their assumptions
were used in our model to perform a separate analysis of the Midway Creek location. In
other words, we have used our method of calculation to make an economic comparison of
the two locations. This includes developing a brief cost estimate.
Using their monthly average streamflows, we calculate the following hydro output and
diesel makeups. These are compared with those calculated in the Dowl report. Where
Midway, Polarconsult is listed are the results from our method of analysis. Where
Midway, Dowl is listed are the results taken from the Dowl report.
Project Annual Demand Hydro Diesel
kWh kWh kWh
Midway, Polarconsult 744,000 658,000 86,000
Midway, Dowl 739,000 665,000 74,000
Barling Bay 744,000 737,000 7,000
The numbers from the Dow] report correspond to the year 1995. Their estimate of the
city's needs was fairly accurate. The difference in diesel and usable hydro energy is most
likely accounted for in our calculations utilizing a daily fluctuation in needs to account
for peak hours. Overall, the comparison is fairly good. Based on these comparisons it
appears the Midway site requires more diesel generation as compared to the Barling Bay
JUNE 29, 1995 PAGE 16
POLARCONSULT ALASKA, INC. OLD HARBOR HYDROELECTRlC
FEASIBILITY REPORT
location. This makes the Midway Creek site more costly. Given that the initial cost is
lower than the Barling Bay site the two locations are nearly the same in yearly savings
over diesel generation alone.
However, an increase in the demand can cause the two projects to take on different
characteristics. For instance, using Dowl's maximum estimated power needs for the
village (871,000 k\Vh, a 17% increase), the following values result.
Project Annual Demand Hydro Diesel
kWh kWh kWh
Midway, Polarconsult 871,000 737,000 134,000
Midway, Dow! 871,000 751,00p 120,000
Barling Bay 871,000 855,000 16,000
The Midway project is capable of producing approximately 85% of the village's power
needs while the Barling Bay project is capable of producing about 98%.
Polarconsult' s cost estimate of the Midway Creek location shows that it may be less
expensive than the Barling Bay location. When adding in diesel makeup power, the total
yearly cost of the two projects is nearly identical. The Barling Bay location is favored
over the Midway Creek location even at an identical net cost for the following reasons.
The location of the Midway creek project is such that it will be accessible only by boat.
This will be an inconvenience during the winter months. The Barling Bay location will
be readily' accessible by road.
Also, when considering increases in the village's power needs, the Midway Creek
location lacks the extra capacity for expansion. This is seen clearly in the comparison of
the cumulative power output graphs shown below. This also applies to water flows. If,
for some reason, there is less water than predicted at both sites the Barling Bay location
will still be able to provide the village with nearly the same amount of power whereas the
Midway location will be augmented with a significant amount of diesel makeup.

The hydro plant will permanently remove water from the Barling Bay tributary. Because
of the significant number of flow contributions that occur downstream of the intake, it is
expected that there will not be any impact to fish in the Barling Bay Tributary. Further,
the area where salmon can spawn has been reported by the Mayor, Rick Bern, to go dry.
The added water to Lagoon will have no appreciable effect on that creek.
FERC
The Federal Energy Regulatory Commission has jurisdiction over most of the hydro in
the US. FERC's jurisdiction is when a hydroplant utilizes Federal land, is involved with
Interstate Commerce, is on a Navigable River, or uses water from a Federal dam or
Project.
The proposed project is partially on Federal land. This means that the project will have to
go through the FERC licensing process. This licensing requires public hearings and a
number of other steps which take a considerable period of time. It is assumed in the cost
estimate that $80,000 will be spent obtaining a FERC license.

This project is within the Kodiak Wildlife Refuge. This could be a major impediment.
Hopefully, however, the agency will see the environmental advantages of this project as
compared to hauling oil and will actively promote the project.
PERMITS
Permits will be required as follows:
I. A water use permit will be required from the Alaska Department of Natural
Resources (D~R). DNR will ask for comments by the Alaska State Department
of Fish and Game (ADF&G), and the Department of Environmental Conservation
(DEC) in the review of these permits. It is unlikely but ADF&G may ask for
special conditions, such as minimum stream f1ows.
2. Alaska Coastal Zone Management Consistency Review Compliance.
3. DEC Clean Water Certification 401 which is done in conjunction with DNR's
review. This permit is required only if a Federal permit is needed. A typical
Federal permit which will require a 401 is a 404 permit for action involving a wet
land or fill in a stream. Without fill, a 404 permit will not be needed, therefore a
401 permit will not be required either.
4. FERC license.
5. A 404 permit will be required for stream excavation. If the size of the intake is
small it may be possible to avoid this permit.
CONCLUSIONS
Based on the analyses in this report, the conclusion is that a hydro plant is superior to the
current diesel generation under almost all reasonable scenarios and that the most feasible
location is the high head plant located on the upper stream of the Barling Bay tributary.
Hydro is superior to diesel generation in a conventional economic sense as the base
project yields a present value of $1,145,194 for the difference between hydro and the
diesel alternative.
In addition to being superior economically, the plant will be superior in an environmental
sense as it will not discharge carbon dioxide nor nitrous oxides into the atmosphere. It
will reduce the risks that are a part of handling fuel. The design of the plant, in addition to
reducing costs, fits into the terrain and requires the very minimum of earthwork. The
generation facility is outside the community and will considerably reduce air and noise
pollution in Old Harbor, or anywhere tor that matter.
There are a number of indications that the US, in an attempt to reduce payments to
foreigners, will create an increase in the costs of diesel fuel. With the hydro the use of
diesel generation is reduced to about 1% of its current use so changes in the cost of diesel
fuel will have no appreciable impact on the cost of power.
The plant will provide employment for the community for much of one year. The
community, instead of sending money out to pay for oil, will capture the labor portion of
PAGE19

FEASIBILITY REPORT
the project. This will have multiplier effects throughout the community, and increase
prosperity. The diesel plant will not provide these benefits.
RECOMMENDATIONS
There are a number of advantages that can accrue to the people of Old Harbor if a
hydroplant is constructed. If these advantages are to be acquired it is recommended that
the following steps be undertaken.
• Install a stream gauge in the east fork of the Barling Bay tributary.
• Ascertain whether the people believe it is in their best interest to build the
plant. If pursuing the project is favorable, then the following additional steps
be taken.
• Get a grant from the Legislature to design and construct a portion of the plant.
King Cove has a grant which funds a large amount of their hydro plant's cost.
The Railbelt has been granted money for Bradley Lake. The 4 dam pool has
received great amounts of largess from the state. It would seem that equity
should result in equal consideration for Old Harbor. Governor Knowles likes
to keep money within Alaska and philosophically supports the concept of the
plant.
• Money can be borrowed from the revolving power loan fund at low interest or
from the Alaska Industrial Development and Export Authority, Farmers Home
Administration, Municipal Bond Bank, or other sources.
• Only consider doing the work with force account. Be very careful with
management of the project. Non innovative construction people who are
accustomed to high cost state government projects can ruin a small project like
this. Paraphrasing Shumaker, think small. Give the project manager absolute
authority to fire people who are not performing. There is no money for feather
bedding.
• Plan to and execute methods of taking advantage of the excess energy that is
available to reduce costs, decrease pollution, and improve the quality of life in
the community.

FEASIBILITY REPORT
The sensitivity analysis gives an indication as to what are the most critical factors
effecting the economic viability of the hydroplant project This analysis focuses on the
primary factors that determine the cost and feasibility of the project. These are:
• Project construction costs.
• Old Harbor's electrical demand.
• Estimate of future diesel fuel costs.
• Quantity of hydro production based on variations in water flow.
The following charts and tables show the effect of these variables on the economics.
Only the stated variable is changed at one time while all the other variables are as those
listed in Appendix A, Economic Assumptions.

Hydroplant Cost (millions of dollars)
As can be seen from the graph above, the project will continue to be economically
feasible for a considerable increase in the estimated construction cost This only applies
at the interest used for the loan in the base case.
The City's power demand needs will effect the profitability of the hydroplant also. As
the following graph illustrates, increases in the City's demand cause a significant increase
in the net present value difference between the hydro and non-hydro power generation.
Similarly, decreases in the City's power needs will reduce the economic feasibility of the
hydro project.

One of the biggest factors in determining the output of the hydroplant, and thus it's
profitability, is the amount of water available in the stream. As was mentioned in the
report, there are no long term records of Barling Bay Creek. Micro climates can be very
significant around mountains and inlets. For this reason, further stream gauging should
be done along with input from the community as to rainfall, snowfall, and general
streamflow conditions in the creek over the years.
The following graph illustrates the effect of streamflow on the feasibility of the project.
This project provides much more power than the community needs and therefore a lower
flow than that estimated does not significantly impact the economic viability of the
project. Also, because it is a high head plant the required flow for the turbine is small.
Even predicted average streamflow values that are half as much as the actual gauged
values are more than 3 times the plant's maximum flow.

First Year Report7 August 1994
Alaska Department or Natural Resources
Division of Mining and Water Managemene
~aska Hydrologic Survey
In May 1993, the Department of Natural Resources, Division of
Mining and water Managementt Alaska Hydrologic survey (AHS}
contrac~ed with the Department of community and Regional Affairs,
Division of Energy (DOE) to qaqe an unnamed stream 2.7 mi
northwest of Old Harbo~, Kodiak ~sland, Alaska. The purpose of
the stre~ gaging is to cbarac~erize the flow of the unnamed
creek in order to assess the viability of the stream as a
hydroelectric energy source for the city of Old Harbor.
The un~amed creek flows south from a high elevation of l80o ft to
the gaging site at 490 ft, and drains an area of 4.6 sq mi. The
highest elevation in the basin is 3500 ft, and snowfields exist
at the higher elevations into mid summer. Approximately 3 mi
downstream of the gage site 1 the stream flows into Barling Bay,
2 mi southwest of Old Harbor. ~he powerhouse for the proposed
hydropower project is situated l mi northeast of Old Harbor at an
elevation of nearly 100 ft, for a head drop of approximately 390
ft.
No long-term weather or streamflow records are available for the
Old Harbor area. Weather information was collect~d in Old Harbor
from 1966-1971 and the average precipitation was 45 in.r with
average temperatures ranging from 37-45 degrees. Precipitation
isohytel maps indicate a mean annual rain-and snowfall of 50-70
in. for the Old Harbor area. Because of orographic effects,
precipitation in the drainage basin above the unnamed creek would
-1-
FEB-7-95 ~UE 15:2~ ::i. U. 11. VJ V. Ut ~t1lt.ti.
be higher, perhaps on the order of so-so in. annually.
Hydrology
The neare$t long-term stream gage in the area was located at the
Upper Thumb River, 24 mi north~est of Old Harbor, and was
operated by the u.s. Geological Survey (USGS). Streamflow data
was collected at this site from 1974-1982, and the lB.a sq mi
basin experienced an average discharge of 92 cubic feet per
second (cfs) or approximately 5 cfs per sq mi.
~~~~~ ~ ~4,~'1
The discharge per unit area can be used to estimate the f" ~·· ;.;~,if~. i,i ~!
streamflow for ungaged basins. However, precipitation in the
Upper Thumb River basin should be less than that at Old Harbor,
because the trend for Kodiak Island is tor precipitation to
decrease across the island from the southeast to northwest.
Assuming the drainage basin characteristics are s~ilar, the
discharge per unit area at the Upper Thumb River will be less
than the discharge per unit area for the unnamed creek.
Consequently, the aean annual streamflow per unit area for the
unnamed creek could be 6-7 cfs per sq mi, equivalent to an
estimated 2B-32 ots.
The attached data report provides stream stage and flow figures
for the unnamed creek from July 14, 1993 to March 20, 1994. The
data collected so tar shows an average flow of 56 ofs, or nearly
double the estimated flow given above.
There are three possible explanations for the discrepancy in
average flow. First, the data collected from the unnamed creek
was for a relatively short period of time that may not be·
indicative of long-term precipitation and streamflow conditions
for the area. Second, the discharge rating curve used to generate
the streamflow data from the recorded stream stages is based on
just four discharge measurements. Four discharge measurements is
-2-
FEB-1-95 7UE 16:2o ::; . u. it IJ J v. ur WHt t.r: r lil\ l't'J, vU I '-'U'-l vU-r
not adequate to define a streamflow rating-curve that is used to
derive long-term fl~~ trends. And third, drainage basin and
cliMate characteristics for the Upper Thumb River gage may not
adequately reflect conditions for the unnamQd creek basin, and
therefore should not be used ror streamflow comparisons.
Until an additional year of streamflow data is collected and
analyzed, the attached streamflow data for the unnamea creek
should be considered preliminary. In particular, flows below 10
cfs or above 150 cfs are suspect because of the lack of data at
the extreme ends of the discharge rating curve. Flows in the J0-
100 cfs range are more consistent and reflect long-term
conditions, with an estimated error of ± ~0%.
Based on the Upper Thumb River data and information from other
Alaska southeoastal areas, the year's highest flows occur in late
May and June from snowmelt, or in septe~er and October from
rainstorms. Low flows most frequently take place from January
through March. Large frontal syste•s can produce heavy rains and
high flows at ~~y time of the year, however. Seasonal streamflow
for the unnamed creek should be the same as those discussed
above.
