INTRODUCTION
Hydropower Development Potential
of
Kenney Lake, Alaska
October 1983
The evaluation of small hydroelectric systems was authorized by
a 1 October 1976 United States Senate Resolution, which directed the
U.S. Army Corps of Engineers to determine the feasibility of
installing small prepackaged hydroelectric units in isolated Alaskan
communities.
In 1982, a regional inventory for small hydrop01-1er projects in
Southcentral Alaska was completed for the Alaska District by Ebasco
Services Incorporated. This inventory analyzed more than 30 sites,
recommending nearly 20 for more detailed examination, including the
Kenney lake site. The Kenney Lake site was one of six selected by
the Alaska District from this group for field reconnaissance and
additional analysis. Ebasco did not conduct any field
reconnaissance at the Kenney Lake site during the Southcentral
inventory.
During 9-11 August 1982, an interdisciplinary Alaska District
team cond~cted a field reconnaissance of a potential s~all
llydropmver project site near the small community of Kenney Lake in
the Tonsina River Valley. The potential site is located across the
Tonsina River from Kenney lake on a small unnamed tributary south of
the Tonsina (see figure 1 and 2). This area is approximately 6
miles south~vest (upstream) of the confluence of the Tonsina River
with the Copper River and approximately 30 miles southeast of
Glennallen.
Presently, the Copper Valley Electric Association (CVEA) serves
the Kenney Lake area. Based on the August 1983 edition of 11 Alaska
Electric Power Statistics" by the United States Department of
Energy, of the total installed nameplate capacity of 22,104 k\~;
12,000 kW are produced by hydropower, 7,304 kW by diesel, and 2,800
kW by gas turbine. A total net generation of 35,941 MWh was
generated in 1982.
ENVIRONMENTAL SY~OPSIS
Principal identified environmental resources in the vicinity of
the site and the stream are Coho salmon, Chinook salmon, and Dolly
Varden. The lower reaches of the stream are used as rearing habitat
by juveniles of those species. Chinook salmon were observed
spawning at the juncture of the subject strea~ and the Tonsina
River. Juvenile salmon were collected upstream of observed spawning
sites. The upstream extent of salmon spavming, juvenile rearing
habitat, and resident Dolly Varden distribution (if any) was not
determined. The fish populations involved are believed to be small
and it appears that impacts to identified fish populations and
habitats could be mitigated to within acceptable limits, possibly
with minor adjustments to optimum project design and operating
regimes. The stream undoubtedly contributes macroinvertebrates,
algae, and other food-web components to the Tonsina River. Minor
losses of these organisms would occur from project operation, but
these losses could not be regarded as significant to other systems.
Moose, black bear, brown bear, and a variety of furbearers in
the canine, weasel, and rodent families occur in the area.
Reconnaissance-level biological surveys indicate that project
construction and operation would have little adverse effect on these
animals, provided that construction and operation access could be
achieved without road construction. If an access road were
required, significant project impacts and secondary impacts from
improved access would likely occur to local wildlife populations.
No endangered or threatened species were observed or identified
in a brief literature search. No cultural resource survey or
inventory has been conducted.
HYDROLOGY
Description of the Area. The unnamed stream has a drainage area of
7.8 square miles. Waters~ed elevations range from about 2,400 to
6,000 feet msl. Significant snowpack exists in the higher
elevations (above 5,000 feet msl}, especially on the north and west
slopes, but no glaciers exist in the study area. Stream slopes in
the area average about 650 feet per mile with a maximum slope of
about 860 feet per mile. Drainage area ground slopes range from
essentially horizontal to nearly vertical. The lower elevations are
covered by dense stands of willow, alder, and birch, while the
intermediate elevations are covered with tundra plants and, where
surface water is available, stands of alder. The higher elevations
are either bare or covered by tundra plants. The stream on which
the dam woulo be located consists of a series of cascades and
waterfalls from the headwater area to the proposed powerhouse
location. In general, the stream is about 12 feet wide with depths
of up to about 1.5 feet between cascades and up to about 4 feet in
the energy holes at the cascades. Site investigations indicate that
stream stage fluctuations have been very minor in the past and the
stream does not appear to have sediment problems above the damsite.
Design Flows. Stage and/or discharge data in the vicinity of Kenney
Lake, Alaska, are very limited. The only gaging stations which have
existed in the area are the Little Tonsina River near Tonsina (USGS
gage number 15207800, drainage area= 22.7 mi2), Squirrel Creek at
Tonsina (USGS gage number 15208100, drainage area= 70.5 mi2), and
Tonsina River {USGS gage number 15208000, drainage area= 420 mi2).
Of these three stations, only the Tonsina River at Tonsina gage is
presently in operation. The period of record mean annual flows for
each of these three streams is given in Table 1.

The Tonsina River unit flows were obviously higher than those of
the other two stations, especially the Squirrel Creek station, but
they were not extremely different from the Little Tonsina River
florJS. The preliminary design flows for the Kenney Lake hydropower
project v1ere developed by multiplying the mean monthly Tonsina River
flows in cubic feet per second per square mile by the Kenney Lake
drainage area in square miles. This resulted in flows slightly·
higher than what would probably have occurred at the Kenney Lake
dams ite.
ENERGY USE
Records for 1982 indicate that CVEA generated approximately
35,941 MWh. Currently, CVEA purchases energy generated by
hydropower from the Alaska Power Authority during the summer. This
time period corresponds with the time period in which the Kenney
Lake project would operate.
Energy Analysis. The HEC program "Hydur" was used to compute the
energy pt·oduction for a variety of project sizes. An overall plant
efficiency of 0.86, a design head of 800', and a minimum operational
capacity of 0.4 times the design caoacity were used as part of the
"Hydur" input data. The results are summarized below.

Benefit Analysis. At this level of analysis, it was assumed that
the total average annual energy of the hydropower system less an 8
percent transmission loss would be equal to the usable energy. Two
categories of benefits were determined for each turbine size;
displaced existing hydropower and displaced transmission costs. An
existing hydropower generation cost of 3.6¢/kWh (Copper Valley
Electric Association, Inc.) combined with a transmission cost of 7.5
¢/KW results in a total energy displacement cost of 11. 1¢/kWh.
Shown below are benefits derived for each of the turbine sizes.

Cost Analysis. A preliminary cost estimate was derived for each of
the project sizes. ·Shown is a summary of project features.

miles of transmission line, the powerhouse plus associated features,
intake structure, helicopter support during construction, site
preparation, mob and demob, a 20 percent contingency, 12 percent for
E&D and S&A; and interest during construction based on a 2-year
construction period. This cost estimate does not include O&M
costs. Costs were amortized using an interest rate of 8 1/8 percent
and a 50-year project life. Shown below is a summary of the
estimated costs.

EVALUATION
. To derive the optimum project size and the net benefits, annual
costs were compared against annual benefits. In addition, a cost
per kWh was derived by dividing the project annual cost by the
project's equivalent usable energy. The results are summarized
be 1 Or/,
Plant Size Annual Annual Benefit/Cost
(kW) Costs Benefits Net Benefit Ratio $/kl~h --300 $ 623,000 $150,000 -$473,000 0.24 $0.46
700 $ 673,000 $275,000 -$398,000 0.41 $0.27
1 '500 $ 772,000 $527,000 -$245,000 0.68 $0.16
2,000 $ 824,000 $568,000 -$256,000 0.68 $0.16
4,000 $1,126,000 $685,000 -$441,000 0.61 $0.18
The above analysis indicates that none of the turbine sizes
evaluated is economically feasible. Plant sizes versus net benefits
were graphed to determine the optimum project and to determine if
any feasibile units exist within the range selected (Graph A). The
optimum project size was found to be a 1,500 kW system with a
benefit/cost ratio of 0.68 which would produce negative net benefits
of $245,000. ·
CONCLUSIONS
The project would produce power during the warmer months so that
power could be fed into CVEA grid supplementing existing hydropower
generation. It appears that a 11 power produced by the hydropower
project could be used in the CVEA system. During the winter, no
power would be generated due to ice, and the power flow would be
from the CVEA d i ese 1 generators to the Kenney Lake area. It can be
concluded that, even ~"ith the optimistic assumptions made on the
streamflow estimates used in the above analysis, no feasible project
size exists.
RECONt·lENDAT IONS
It is recommended that no further Corps of Engineers studies of
hydropm'ler deve 1 opment at Kenney Lake be undertaken at 'this time.

V~ldez and Copper River Basin
Energy Usage Update
With Emphasis on Kenney lake
Si1ee the •Electrical Power for Valdez and the Copper River B~sin•
study t,ras completed in March 1981, significant chanQes have taken place
in the Valdez-Glennallen area. Factors influencing demand increases and
options to meet those increases have changed. The-cancellation of the
propos~d oil refinery by the Alaska Petrochemical Company (ALPETCO) has
great 1:' reduced demand over that previously estimated and the
instit~tional problems associated with the proposed pressure reducing
turbin~ have appeared to all but eliminate that as a generating
alternative. This is particularly true because the Prudhoe Bay field's
economic life will be ending in the mid-1990's and the prospect of
additional finds in the area are much bleaker with a dry hole at Mukluk
we 11 1 n 1983.
Th~ following briefly examines what has happened regarding energy
projec~ions, the impact of Solomon Gulch, and conclusions on hydropower
1n the area (Kenney Lake and Allison Lake).
Loa0 F)recast -Reality vs. Projections
Th:; load forecast deemed most likely in •£1ectr1~1 Power for Valdez
and th~ Copper River Basin• indicated additional diesel generation may be
needed after the year 2000 (Figure C-2). This forecast was based on the
assumption that ALPETCO would build a refinery in Valdez. At the time
the report was being finalized, ground breaking had begun for the
project. Shortly thereafter ALPETCO cancelled their plans to build the
refinery. It then appeared that Dow-Shell would go ahead with a
petrochemical complex at Valdez. However, due to the recent oil glut,
all plans have been put on hold indefinitely. Therefore, load growth has
been substantially slower than originally assumed. The following table
summarizes the gross generation from the Solomon Gulch hydropower plant
and fo~ diesel plants at Glennallen and Valdez.

The actual generation reporte( ahove compares with the "revispd APA" and
the "low growthM scen~rios r~rorted in "Electrical Power for Valdez and the Copper River Basin" as follows.
Actual~ RevisE:d APA % Difference Low Growth t Difference
Year ( GWh) {GWh} Ac1ual vs. Estimated (GWh) Actual vs. Estimated
1980 45.1 47.9 -5.8 47.9 -5.8
1981 46.3 52.0 -11.0 so. 1 -7.6
1982 51.9 55.5 -6.5 52.5 -1.1
1983 52.2 61.0 -14.4 55.0 -5. 1
As can be seen by the preceding summary, the actual demand has fallen
short of the low growth forecast by approximately 5 percent to date,
while falling over 14 percent behind the revised APA forecast, which was
considered •most likely11 at the time the report was published.
Based on the above and the assumption that Allison Lake hydropower
will be the next addition, it appears that the time when additional
energy is neede:· to displace diesel in the SUIIIller months will be
significantly l~ter than 2000.
Solomon Gulch Enerqy Production
Since coming on line in J~~uary 1982, Solomon Gulch has contributed
significantly to decreasing the reliance on diesel fuel in the
Valdez-Glennallen area. For t~e first 2 years of operation, the system
has carried the entire utility's load from mid-May to late October. In
late October when Solomon Gulch stops spilling, the transmission line
from Valdez to Gelnnallen is de-energized. From then until mid-May,
Glennallen is solely served by diesel-fired generators while Valdez is
served by a diesel-hydropower combination until late March or April when
the reservoir •bottoms out.11 Valdez is then served solely by diesel
until m1d-May when runoff begins to fill the reservoir. According to Mr.
John Hunter, the operator at Solomon Gulch, the commencement of runoff is
so sudden and fast that once t~e reservoir begins to fill, the
Valdez-Glennallen transmission is energized and Solomon can again carry
the full load. In the first 2 years of operation, the reservoir was
filled and began spilling on 19 July in 1982 and 11 July in 1983. It
continued to spill until 18 October 1982 and 19 October 1983.
Although a detailed record of the inflows and spill quantities were
not readily avai table, Mr. Hunter estimated that. based on the amount of
water available, Solomon Gulch could run at full capacity (12 MW) from
May to October with no impact on winter flows because of the large
quantitv of water spilled. This compares to a current peak demand (which
occurs in winter) of approx1ma~ely 9 MW. The peak summer demand is
estimated to be about 2 HW les5.

Conclusion
loads have not materi~lized as anticipated in tlP Valdez-Glennallen
area due primarily to the cancelled development of the ALPETCO oil
refinery. These reduced loads, combined with Solom)n Gulch's capability
to produce an abundance of energy during the summer months makes
development of a project that only produces energy in the summer months
(like Kenney Lake) unattractive in the Valdez-Glennlllen area. Any
benefits to be derived from displaced diesel fuel h the summer months
could not be claimed until possibly 2010 or later. Therefore, the
evaluation of Kenney Lake (or any other small hydro~lower project in the
area) should be measured against hydropower at Solo~on Gulch rather than
diese 1.
A project with great reservoir requlation to di~place some of the
16 GWh annually that are still produced by diesei generation is needed in
the Valdez-Glennallen area. Because the pressure reducing turbine no
longer appears feasible due to the institutional problems encountered to
date and the ever-shortening life of Prudhoe Bay, tne most reasonable
alternative appears to be developmE>n~ (\t Allison Lake. as previously
proposed.
