“The Bradley Lake funding model combines an equity contribution from the State of Alaska
equal to 50 percent of the turnkey project costs and 50 percent of the turnkey cost through
tax‐exempt financing via State‐sponsored tax‐exempt bonds. Tax‐exempt bonds were
available to the project due to the ownership by the AEA. The Bradley Lake Agreement
provides for Excess Payments equal to the average annual debt service that commence once
the bonds have been paid in full. The final bond payment is expected in year 30 of the
project (2021), which will trigger the Excess Payments in year 31 that continue until
original termination date of the agreement in year 50 of the project (2041). All purchasers
have the opportunity to renew for an additional 40 years (or whatever the remaining
expected life expectancy is). The Excess Funds payments to the State are to be deposited in
the Railbelt Energy Fund to support the construction of a high‐capacity transmission system
from Fairbanks to the Kenai Peninsula. The take‐or‐pay Power Sales Agreement provides
security from each utility participant for the project revenue bonds.
The Power Sales Agreement also establishes the Bradley Lake Project Management
Committee (BPMC) that consists of participating utilities and the AEA to govern the
6
July 2012
operations and maintenance of the Bradley Project. The BPMC is required to establish a
Renewal and Contingency Fund to provide funds for approved project modifications and
repairs as part of the Bond Resolution. Operations and maintenance of Bradley Lake is
provided under contract with Homer Electric. Dispatch and scheduling of the project
electrical output is by Chugach Electric’s dispatch center.
Based on the five series of bonds issued to date, the average annual debt service is
$12.3million. The initial equity contribution by the State drastically reduced the on‐going
effects of interest‐during‐construction on the debt.
The Bradley Lake Project has a nameplate capacity of 126 MW and produces approximately
375,000 MWh of energy per year.”
Section 10
Page 10‐6, Last Paragraph. Add the following to the end of the paragraph “Black & Veatch and HDR
have broadly characterized the potential projects as “storage” or “run‐of‐river” in Table 10‐2.

make it difficult to construct wind” to “the uncertainty associated with the rule adds uncertainty to
potential wind.”
7
July 2012
Page 11‐8. After first paragraph, add the following paragraph “Subsequent to the issuance of the
Draft Southeast Alaska IRP, the Kake, Alaska Wind Resource Report was published on January 6,
2012. Black & Veatch’s comments on the report are as follows. The Kake wind power data as
presented is from well regarded measuring equipment. The placement of anernometers at 20 m
and 34 m provides one less data set and requires greater extrapolation to hub height than industry
standards, though the wind resource measured seems worthy of further review. Positive indicators
include the wind power density benefiting from high air density, seasonal resource variation
correlating with load variation, and the consistency of wind direction evidenced by the wind rose.
In the next phase of analysis, a potential wind site developer would give greater consideration to
specific turbine locations that would have less turbulent winds. These may be hilltops as mentioned
in the report, but these potential sites would need to be selected based on constructability and
ability to bring generated power to the load. Power production at the site would benefit from
additional turbine height beyond the 37 m hub height of the 100 kW Northwind 100 B model
turbine identified. Further wind speed investigation may be warranted for potentially higher hub
heights using alternative technology such a lidar or sodar, if towers and associated turbines would
be available in the market for those higher hub heights.”

Page 11‐16, Above Section 11.7. Insert following paragraph “Small biomass gasifiers are currently
under development, but have not reached a demonstrated commercial status. Converting biomass
gas to electricity also is subject to technical challenges at small scales. The biomass gasification
technology is still developing and has not yet demonstrated that it will provide reliable power at
significantly lower costs than diesels.”
Page 11‐18, Section 11.9. Add following paragraph at the end of section “SEACC recently completed
a performance evaluation at a small residential solar photovoltaic (PV) in Angoon as a part of the
Sustain Angoon Demonstration Project: Photovoltaic Installation. The evaluation calculated
payback period of 11.5 years based on the pre‐PCE rates. Based on the data in the evaluation and
eliminating the cost of the battery back‐up system, Black & Veatch estimated the 2011 cost of
energy for the system to be $597/MWh which compares to the diesel generation cost of $255/MWh
presented in Table 12‐12. Behind the meter dispersed generation such as the Sustain Angoon
Demonstration Project obtain savings based on the retail electric rate, but the majority of the non‐
fuel cost savings would in turn increase the non‐fuel cost for other customers PV prices have been
declining and as stated above the solar PV alternative should be monitored, but its current high
price precludes it from further consideration in the Southeast IRP at this time.”
Page 11‐20. Add new section as follows “11.10.1.4 Geothermal ‐ Subsequent to publication of the
Draft Southeast Alaska IRP, a notice of the Draft Supplement to Update Analysis in the
Programmatic EIS to Address Roadless Concerns, Consideration for Lease Approval, Bell Island
Geothermal Leases was published in the Federal Register on May 18, 2012.”

for long‐term storage could be pumped storage. Normally pumped storage projects are designed
for daily storage or at the most weekly storage. For a project to have significant long‐term storage,
it would need a very large upper reservoir. Costs for pumped storage can be high depending upon
the specific situation. Black & Veatch did not identify any potential sites in Southeast Alaska that
appear to be good candidates for long‐term pumped storage.”

Report, Polarconsult Alaska, Inc., issued a draft report for Phase II of a study, funded by the Denali
Commission, to develop a low‐power HVDC transmission technology suitable for rural Alaska.
According to Polarconsult, the Phase II findings indicate that the HVDC transmission systems
developed under this program will significantly reduce the cost of Southeastern interties. Black &
Veatch has not conducted an independent evaluation of this study but agree this option warrants
more detailed consideration in the years ahead.”

Agreement #00CO‐111005‐105 or no later than February 1, 2001, there is hereby authorized to be
appropriated to the Secretary of Energy such sums as may be necessary to assist in the construction
of the Southeastern Alaska Intertie system as generally identified in Report #97‐01 of the Southeast
Conference. Such sums shall equal 80 percent of the cost of the system and may not exceed

State or Federal law.”
Page 12‐51, Following Above Paragraph. Insert following paragraph “If the necessary
appropriations are made, the funds could improve the benefit‐cost ratios from a State perspective,
but would not change them from a public benefit perspective. The maximum level of assistance of
$384 million is much less than current estimates to complete the remaining portion of the
Southeast Alaska Intertie. From a practical standpoint, Black &Veatch believes that it will be
difficult if not impossible to obtain this funding for the interconnections, but nevertheless, it
represents a possible source of funding.”

Page 15‐10, Section 15.5, End of First Paragraph. Insert “The conversion program estimate is an
estimate of the savings that might be achieved if a major program were undertaken. Key to the
estimate is the assumption that all the capital cost associated with conversion would be provided
by State or other assistance. Thus the customers would not have out‐of‐pocket capital expense
associated with converting to pellets and would have significantly lower operating costs. With such
aggressive assumptions, a high level of penetration of conversion could be expected. For this
estimate a penetration of conversion from oil to pellets is assumed to be 80 percent over a ten‐year
period. While some people may think that such a penetration level is unrealistic, it is merely used
to estimate the savings that might occur. The key assumption is that all capital costs of conversion
are assumed to be provided to the customer and are included as costs in determining the potential
savings. This would be similar to estimating what the penetration of electric vehicles would be if
the State or some other organization were to pay the entire cost of the electric vehicle so that the
customer would have no out‐of‐pocket expense. The penetration level would undoubtedly be very
high. The actual penetrations associated with a pellet conversion program will need to be
developed as part of the detailed program development. For comparison purposes, Black & Veatch
has also presented the savings if the penetration level were 30 percent over ten years in Section
1.0.”

capital costs in return for contracts with customers to provide the pellets.”

“Another issue for consideration in the detailed DSM/EE program development is that these
utilities with higher diesel and non‐fuel costs are in the PCE program. Savings in energy
consumption can reduce PCE payments by the State if customers are using less than the PCE
threshold of 500 kWh per month. These reduced PCE payments may be a source of funding for the
DSM/EE programs. Also if the savings in PCE payments could be utilized to off‐set non‐fuel costs,
more programs would be cost‐effective under the RIM test for high cost utilities. These, as well as a
number of other considerations, will need to be included in the detailed program development.”

16.3.3 Heat Pump Options (Air‐source and Ground‐source)
Another option for the provision of residential space heating instead of traditional electric furnace
heating is the use of a heat pump system. A brief discussion of heat pump options is provided
below, including the recently released results of a 15‐year study evaluating the feasibility of heat
pumps operating in Alaska.
The heat pump technology transfers energy from the outside air, ground, or water into a home and
can also reverse the transfer. A heat pump brings warm air into the home during heating season
and can take heat out of the home during cooling periods. To perform work, heat pumps use an
intermediate fluid called a refrigerant that absorbs heat as it vaporizes and releases the heat when
it is condensed. The two most common types of heat pumps are air‐source and ground‐source heat
pumps (GSHPs).
The air‐source heat pump is the most common type of unit installed in the United States due to its
low cost relative to the ground‐source system, its reliability, and its economy compared to the
traditional alternative of heating a home with an electric or gas‐fired furnace and cooling with an
air conditioning unit. Figure 16‐1 illustrates the conceptual operation of the air‐source heat pump.
When in cooling mode, the heat pump evaporates a refrigerant in the indoor coil; as the liquid
evaporates it pulls heat from the air in the house. After the gas is compressed, it passes into the
outdoor coil and condenses, releasing heat to the outside air. The pressure changes caused by the
compressor and the expansion valve allows the gas to condense at a high temperature outside and
evaporate at a lower temperature indoors.
Figure 16‐1 Air‐Source Heat Pump Cooling Cycle30
A typical savings in electricity of 30 to 40 percent is achievable for most U.S. locations using air‐
source heat pump technology.31 However, the efficiency of air‐source heat pumps in the heating
mode decreases significantly at low temperatures, making them uneconomical or marginal for
colder climates. Typically air‐source heat pumps have a coefficient of performance (COP) of around
3.0 at moderate temperatures. The COP reduces as the temperature decreases and hence the
typical savings of 30 to 40 percent instead of a 67 percent savings that would be associated with a

COP of 3.0. According to the U.S. government, “although air‐source heat pumps can be used in
nearly all parts of the United States, they do not generally perform well over extended periods of
sub‐freezing temperatures.” In regions with subfreezing winter temperatures, it may not be cost
effective to meet all your heating needs with a standard air‐source heat pump.”32 Air source heat
pumps typically have resistance heating as back‐up for use when the temperature becomes cold
enough that the heat pump is no longer effective. When the resistance heating is in effect, it can
place a significant strain on the utility system which is already facing peak loads from the low
temperatures. Even if hydro generating units have the capacity to handle the increased load from
the resistance heating being used, the distribution systems may not be capable of these additional
loads. Air‐source heat pumps generally require a ducted system. While there are many specifics
associated with the costs of heating systems, air‐source heat pump systems would be on par with
oil‐fired boilers, electric resistance boilers, and pellet furnaces and would be more expensive than
baseboard resistance heat. Air‐source heat pump systems are not as suitable for replacing oil boiler
systems due to the need for ducts.
There are newer systems, and systems in development, that aim to overcome the problems
associated with heat pump operation in colder climates, but these will likely require a higher
upfront cost than common air‐source heat pumps. These mini‐split heat pumps (MSHPs) have the
advantage that they are ductless. They also have higher SEERs and COPs. However, according to
the Laboratory Test Report for Fujitsu 12RLS and Mitsubishi FE12NA Mini‐Split Heat Pumps33,
these MSHPs have several issues that must be resolved before MSHPs can achieve broad market
penetration in the U.S. MSHPs are likely more expensive than high SEER forced air systems
particularly when installed in an average size house which will typically require multiple indoor
units. Also some homeowners may not prefer MSHPs for aesthetic reasons and thus they may not
be able to be installed in every room potentially resulting in reduced comfort.
While the MSHPs can operate at lower temperatures, their output and COPs reduce significantly at
lower temperatures. Figures 16‐2 and 16‐3 present the COP test results for the Fujitsu 12RLS and
Mitsubishi FE12NA respectively. A similar result occurs for heating with the heating capacity
reducing substantially with decreasing temperatures. Figures 16‐4 and 16‐5 present the heating
capacity test results for the Fujitsu 12RLS and Mitsubishi FE12NA, respectively. The decreasing
heating capacity with decreasing temperature results in greater capacity and corresponding greater
cost required to meeting heating requirements. In general, it is Black & Veatch’s opinion that the
capital cost of MSHPs are higher than comparable electric boilers, oil boilers, and pellet furnaces.
While a COP of 3.0 is typically used in economic comparisons of heat pumps, the COP over the
actual heating range will likely be less than 3.0 for MSHPs which have higher COPs than air‐source
heat pumps. When actual end‐use data becomes available for Southeast Alaska, more detailed
evaluation of the efficiency of heat pumps, both air source and MSHPs, will be necessary to
determine their cost‐effectiveness as part of DSM/EE or space heating program.

While potentially promising, Black & Veatch does not view MSHPs as being sufficiently
demonstrated to commit to an extensive program involving their installation at this time. They
certainly aren’t demonstrated to the extent that air‐source heat pumps, ground source heat pumps,
and pellet stoves have been demonstrated. Other designs may be available and developing, but
they will have difficulty overcoming the fundamental laws of thermodynamics during cold weather.
The GSHP is more costly to install than an air‐source heat pump but it achieves a higher efficiency
and is more suitable for application in colder climates such as Alaska. In Sweden, for example, 30
percent of the homes have GSHP systems.34
GSHPs collect the natural heat of the ground through a “loop” or series of hard plastic (usually
polyethylene) tubes that are installed below the ground or, sometimes, submerged in a pond, lake,
or seawater. The tubes are filled with a moving fluid that carries the transferred heat into the home
where the heat pump’s compressor and heat exchangers convert the heat to a higher temperature
(when in heating mode) and release the heat into the home, usually through a blower and duct
system. It is the near‐constant temperature of the ground around the loop system (depending on
location, the ground temperature at a depth of 6 feet in the U.S. is between 45° and 75° F) that
allows the GSHP to operate more efficiently than an air‐source heat pump in the winter and other
heating periods.35
Depending on location and other factors, a GSHP can use 25 to 60 percent less electricity than
conventional alternatives according to the U.S. government and, depending on location, is usually
able to recover the higher initial investment cost over a 2‐ to 10‐year period through lower utility
bills.36 Ground‐source systems also have the benefit of being very reliable and a typical loop
system will be guaranteed 25 to 50 years by the manufacturer. Currently, about 50,000 GSHPs are
installed in the U.S. each year.
In 2011, a 15‐year study of the economics of GSHPs in Alaska was completed by the Cold Climate
Housing Research Center and the Alaska Center for Energy and Power. The locations studied were
Fairbanks, Anchorage, Juneau, Bethel, and Seward. The study ‐ “GroundSource Heat Pumps in Cold
Climates: The Current State of the Alaska Industry, a Review of the Literature, a Preliminary Economic
Assessment, and Recommendations for Research” ‐ determined the net present value (NPV) cost of
heating with various options in the five cities evaluated. The NPV at each location was the
discounted value of capital, fuel, electric, and other operating costs over a 15‐year period, using a 3
percent discount rate. The results are summarized in Table 16‐8 and indicate that the relative
economics of heat pumps in Alaska are highly dependent upon the cost of the primary heating
alternatives of electric resistance heating, oil‐fired boilers, oil‐fired laser vented heaters and, in
Anchorage, natural gas heating.

In Bethel, the high cost of electricity ($0.54/kWh after the first 500 kWh each month) caused the
cost of electric resistance heating to be most costly, followed by GSHPs and then by oil‐fired
heaters.37 Thus, even though the ground‐source heating option was economical compared to full
reliance on resistance heating, the partial reliance of the ground‐source heating option for
supplemental heat from electric sources harmed the overall economics relative to the oil‐fired
heater option.
In Anchorage, natural gas heating was the least‐cost option evaluated, followed by ground‐source
heating and electric resistance heating. In Juneau and Seward, GSHPs were lowest in overall cost,
compared with electric resistance heating and oil‐fired boilers. Finally, in Fairbanks, heat pumps
were slightly lower in NPV cost than an oil‐fired alternative while electric resistance heating was
significantly higher than these two options.
The implication for Southeast Alaska is that, while GSHPs seem to be a viable option for Juneau and
for communities with moderate electricity costs, many of the smaller communities having a high
cost of electricity may be more comparable to the study economics for Bethel, and heat pumps may
be marginal or uneconomic in such locations. Related specifically to Southeast Alaska, the study
concluded the following about GSHPs:
GSHP systems are more viable where electricity costs are relatively low and heating
costs are relatively high. Juneau, included in the economic analysis, displayed this
relationship. These results can be roughly extrapolated to many other communities
in Southeast Alaska that utilize hydropower.38

Literature, a Preliminary Economical Assessment, and Recommendations for Research”, May 31, 2011, p. 23.

The study also surveyed studies of GSHPs in Alaska. The survey contained two studies for Juneau.
In one of the studies the COP ranged from 2.25 to 2.5 and the other study had a COP of 2.0. Thus in
both of the studies surveyed, the COPs for GSHPs were significantly below the COP of 3.0 typically
used in heat pump comparisons. The study that was completed May 31, 2011 surveyed all known
residential GSHP installations in Alaska. Only one installation was identified in the Southeast in
Juneau. The study also estimated the capital cost of GSHPs, oil boilers, and baseboard electric heat
in Juneau. The capital cost of the GSHP was 2.3 times the cost of the oil boiler and 8.9 times the cost
of the baseboard electric heat.
GSHPs are also alternatives for larger commercial buildings and have had a greater penetration in
commercial buildings in the Southeast that the residential penetration presented in the above
study. In Black & Veatch’s view, GSHPs for both residential and commercial applications represent
demonstrated commercial technology. The only barrier to their installation is economics driven by
high capital cost. When additional end‐use data becomes available in the Southeast, additional
detailed study should be conducted before GSHPs are considered as part of a DSM/EE or space
heating program.
Table 16‐9 presents the break‐even electric cost of pellet space heating with heat pumps only
considering energy costs and not capital costs. Table 16‐10 presents the cost of electricity for the
various communities. A comparison between the two tables indicates the communities in which
heat pumps can be cost effective with pellet space heating on an energy basis. When the capital
cost of heat pumps is considered for MSHPs and GSHPs, heat pumps become less competitive. The
average COP for air source heat pumps lowers significantly when the periods of electric resistance
heating are considered during colder temperatures. It is likely that the detailed marketing studies
discussed in Section 15 will indicate that there will be opportunities for heat pumps in some
markets from an economic stand‐point if rate structures are not modified to reflect the costs of
supplying additional electricity to serve electric space heating conversion. For communities that do
not have access to low cost hydro generation, heat pumps will not be cost effective. In all cases
electric space heating conversion will add electric load and consume hydro generation. Heat pumps
will consume less energy than resistance heating, but may not consume less capacity if resistance
back‐up is needed at low temperatures.
Opportunities may exist to convert resistance heating to heat pumps. These types of conversions
would actually reduce energy consumption, but may not reduce capacity requirements if electric
resistance back‐up is required. This type of conversion would best be conducted as part of the
region’s or a utility’s DSM/EE program. This conversion was not evaluated in Section 13.0 since it
would not pass the RIM test. The detailed market studies discussed in Section 13.0 would
determine if a conversion program from electric resistance heat to heat pumps is feasible.

APPENDIX E. Description of Strategist®
Black & Veatch used Ventyx’s Strategist® optimal generation expansion model to evaluate the
various alternatives and scenarios. Strategist® is a computer software system developed to support
electric utility planning and decision analysis. In the Southeast Alaska IRP, Strategist® was used to
evaluate supply‐side resources, develop candidate resource plans, and conduct sensitivity analyses.
Strategist® incorporates several modules, each designed for a specific application.
Generation and Fuel (GAF)
Load Forecast Adjustment (LAF)
PROVIEW
A flexible control system ties the application modules together and automates data transfer from
one module to another. A graphical user interface (GUI) serves as a menu‐driven interface between
the database, output results, and the user. The GUI allows quick examination of the data, full
graphical capabilities, and immediate compilation of output results. The capabilities of each of these
modules and their specific function are discussed in the following sections.
Generation and Fuel Module (GAF)
The Generation and Fuel Module (GAF) simulates power system operation using proven
probabilistic methods. It provides production costs and generation reliability measures (i.e.,
reserve and emergency energy) that are essential to supply‐side and demand‐side planning. The
GAF Module fulfills a strategic planning role in that it requires less computer resources than more
detailed production costing models without sacrificing overall accuracy. All thermal generating
units are dispatched using a computationally efficient probabilistic technique. Each generating unit
is characterized with at least two capacity segments, corresponding heat rates, fixed and variable
O&M expenses, maintenance requirements, and other operating specifications. The thermal unit
segments are dispatched in economic order approximating the economic dispatch procedure of a
system operator. The probabilistic dispatch technique yields production costs and system reliability
indices. A built‐in feature of the GAF Module is its generation expansion scheduling capability. Users
can input targets for minimum reserve margins, maximum loss of load hours, maximum reserve
margins, minimum renewable energy, and other necessary limits. The module also accepts an array
of supply‐side alternatives. The system will automatically schedule additions in such a way as to
maintain the targets specified (see PROVIEW Module). Thermal units, hydro units, or purchase
transactions may be included in the addition list.
Load Forecast Adjustment Module (LFA)
The Load Forecast Adjustment Module (LFA) is a multi‐purpose tool for creating and modifying
load forecasts and for evaluating demand‐side management (DSM) programs. Using the LFA, a
planner may address key issues related to future electricity demand and the impacts attributed to
each customer group. Data is entered at the load group level and consists of a monthly forecast of
non‐coincident peak, energy requirements, and a typical annual shape. Once each load group has
been processed, the resulting loads are transferred to the GAF Module. DSM programs can also be
modeled in the LFA as load groups. Costs associated with these programs are input, as well as peak
and energy reduction values. A load shape for the DSM program enables the LFA to modify the
company load shape in all hours according to the effect the DSM program would have on energy
use.

PROVIEW Module
The PROVIEW Module is a resource planning module which determines the least cost generation
expansion plan for a utility system under a prescribed set of constraints and assumptions.
PROVIEW incorporates a wide variety of expansion planning parameters, including alternative
technologies, unit conversions, co‐generators, unit capacity sizes, load management, marketing and
conservation programs, fuel costs, reliability limits, environmental compliance options, and
financial constraints in order to develop a coordinated integrated plan which would be best suited
for the utility. PROVIEW works in concert with the GAF to simulate the operation of the utility
system. Its optimization logic then determines the cost of reliability and the effects of adding
resources to the system or modifying the load through DSM programs. PROVIEW provides
numerous constraints for the user to reduce the number of options considered, including the
maximum number of on alternatives to add, incremental number to add per year, minimum and
maximum reserve margins, as well as others. Throughout the planning period, PROVIEW derives all
of the possible combinations of supply‐side alternatives that meet the selected constraints. Each
plan is then subjected to an "end effects" calculation whereby the analysis approximates the capital
and production cost of replacing the system (as it exists at the end of the planning period) in kind,
for a given period beyond the planning period . The user has the choice of minimizing different
costs when optimizing. Costs are accumulated by year in nominal dollars and then present valued
for comparative analysis between plans. The planning period and end effects costs are summed to
determine the study period cost of the plan. Plans are then ranked by their study period cost to
determine the least‐cost integrated resource plan.
