4.1 Proposed Energy Resource
Describe the potential extent/amount of the energy resource that is available.
Discuss the pros and cons of your proposed energy resource vs. other alternatives that may be
available for the market to be served by your project.
Potential Extent/Amount of Energy Resource
KPU proposes to operate the project utilizing water stored within Whitman Lake to generate power
and to supply the Whitman Hatchery with water. Total generating capacity of this project would be
4.6 MW, with 16,000 MWh produced in an average year.
KPU proposes to operate Unit 1 between reservoir El. 370 and 379.8 feet msl for the primary
purpose of generating power. Unit 1 would obtain water via the 60-inch diameter penstock
through a new screened intake and would have a minimum hydraulic capacity of 50 cfs and a
maximum hydraulic capacity of 150 cfs. Flows discharged from Unit 1 would enter the project
tailrace and discharge into Herring Cove.
Renewable Energy Fund
Grant Application
AEA 09-004 Grant Application Page 8 of 18 9/3/2008
KPU proposes to operate Unit 2 on a year-round basis for the primary purpose of supplying
Southern Southeast Regional Aquaculture Association (SSRAA) with water. Water would be
delivered to Unit 2 via the 36-inch diameter penstock. Once reservoir levels drop below El. 363
msl, a vacuum pump connected to the deep water intake would be utilized to ensure reliable
operation of the siphon down to El. 343 msl. Unit 2 would have a minimum hydraulic capacity of
12 cfs and a maximum hydraulic capacity of 32 cfs. Discharge from Unit 2 would enter the 30-foot
diameter head tank via a pressurized tailrace. Flows from the head tank would then be controlled
by SRAA for use at the Whitman Hatchery. KPU also proposes to construct a pressure-reducing
valve that would be routed to the head tank in the event Unit 2 goes offline. Any overflow from the
head tank or Unit 2 flow in excess of hatchery demand would discharge into the project tailrace.
KPU proposes to release between 6 and 11 cfs (depending on the time of year) downstream of
Whitman Dam during normal conditions. During dry conditions, a Dry Conditions/Low Reservoir
Protocol Plan would be implemented. Once levels drop below El. 363 msl, minimum in stream
flows would be reduced to flows agreed upon by a Reservoir Action Team (composed of
representatives from KPU, SSRAA, ADF&G, ADNR, and the USFS), or to between 2 to 7 cfs,
depending upon the time of year, if consensus is not reached.
Pros and Cons of Whitman Lake vs. Other Available Alternatives
Pros:
• Uses existing infrastructure previously used for hydropower
• Smaller environmental footprint versus constructing infrastructure for another energy
source
• Diesel fuel is vulnerable to fluctuations of availability and cost
• Minimal transmission lines required to connect to system
• Established technology
• Reduced greenhouse gas emissions in the region due to clean renewable energy
• Decreased dependence on imported fossil fuel
Cons:
Maintaining water supply to SSRAA hatchery restricts operational flexibility
4.2 Existing Energy System
4.2.1 Basic configuration of Existing Energy System
Briefly discuss the basic configuration of the existing energy system. Include information about
the number, size, age, efficiency, and type of generation.
KPU Electric operates an “islanded” system. This means all of KPU’s service territory consists of
islands not connected to a power grid as most electric companies in the world exist. All of the
power distributed by KPU Electric is generated and consumed locally.
Renewable Energy Fund
Grant Application
AEA 09-004 Grant Application Page 9 of 18 9/3/2008
System operations, generation dispatch, and system restoration are controlled from KPU’s Bailey
Plant. A new SCADA system went on line in 2004. A CertaLogic GIS system was implemented in
2004 as well that will improve system records and mapping/planning functions. The new SCADA
master and the new GIS system will work together to facilitate outage management.
Swan Lake Hydro is a remote (accessible only by boat or plane) facility connected to the rest of
the system via a 30 mile 115 kilovolts (kV) line that terminates at our Bailey Substation where it is
stepped down to 34.5 kV. The 34.5 sub-transmission circuit feeds 6 substations that step down to
our distribution voltage of 12.47 kV. The rest of the hydro plants operate at various locations
along the 34.5 kV circuit.
A 57-mile, 115 kV line is under construction that will connect Swan Lake Hydro with Tyee Hydro, a
22.5 MW, the project is currently owned by the Four Dam Pool Power Agency that currently
serves only the town of Wrangell and Petersburg. This Intertie will eventually be a part of the
future “Southeast Intertie” that will connect all the communities of Southeast Alaska with a
common power grid.
Renewable Energy Fund
Grant Application
AEA 09-004 Grant Application Page 10 of 18 9/3/2008
KPU is developing the hydropower potential at Whitman Lake to augment KPU’s resources to
serve the load. Whitman Lake’s generation will reduce KPU’s need to use Tyee’s power.
4.2.2 Existing Energy Resources Used
Briefly discuss your understanding of the existing energy resources. Include a brief discussion of
any impact the project may have on existing energy infrastructure and resources.
Ketchikan’s Existing Generation Resources
• Ketchikan Lakes Hydro and Beaver Falls Hydro (including the Silvis Plant) generates 11.5
MW
• Swan Lake Hydro generates 22.5 MW
• Four-unit diesel plant with a capacity of 23 MW

Another existing energy resource used is diesel plants ranging from a few kWs to 10.5 MW which
supply communities in SE Alaska with firm power, as backup in some communities and as primary
in others. The total capacity of in-service diesel plants in SE Alaska totals 56.65 MW. Fuel prices
vary by community or load center and range from $2.20/gallon in Ketchikan to $2.68/gallon in
Wrangell. Compared to the cost of existing hydro power in the range of $10/MWh to $20/MWh,
and the lowest cost proposed hydro power in the $55/MWh to $87/MWh range, diesel is both
costly to the communities and a contributor to greenhouse gas emissions in the region.
Impacts of Whitman Lake on Existing Energy Infrastructure and Resources
Development of the Whitman Lake Hydropower Project would displace the need for dependence
on diesel generation in Ketchikan. Power from Whitman Lake would be available, not only to
displace the cost of operating diesel generation to replace lost power when the transmission lines
are down, but would also encourage new economic development in Ketchikan and other
interconnected communities in southern Southeast Alaska.

customers.
Existing Energy Market
Ketchikan Public Utilities buys, generates, and resells all of the electricity consumed in the City of
Ketchikan and the Ketchikan Gateway Borough area. KPU owns Ketchikan Lakes Hydro and
Beaver Falls Hydro (including the Silvis Plant) totaling 11.5 MW, and operates Swan Lake Hydro
(22.5 MW) which is owned by the Four Dam Pool Power Agency (FDPPA). KPU also owns and
operates a four-unit diesel plant with a capacity of 23 MW.
Monthly sales and generation dates were available for Ketchikan for the years 2000 to 2006. The
data are summarized on an annual basis below. Although some growth is evident into 2006, total
sales and generation are lower for 2006 than in either 200 or 2001. Monthly sales display
consistent seasonal patterns over the years. Residential sales are markedly lower in the summer,
particularly August and September and peak in December and January. The seasonal pattern for
non-residential sales, however, is less well defined displaying only slightly lower consumption in
the summer and slightly higher in the winter.

Existing Electric System Operations
KPU proposes to construct and operate the Whitman Lake Hydroelectric Project and integrate its
output with KPU’s other generation resources. KPU also owns and operates the diesel-fueled
Bailey Plant (20.5 MW) and two standby units (3.2 MW).
System operations, generation dispatch and system restoration are controlled from KPU’s Bailey
Plant. A new SCADA system went on line in 2004. A CertaLogic GIS system was implemented in
2004 as well that will improve system records and mapping/planning functions. The new SCADA
master and the new GIS system work together to facilitate outage management.
Future Modifications to System Operations
Presently KPU operates as a remote system; with completion of the Swan-Tyee Intertie in 2010,
the Swan Lake Project located near Ketchikan will be interconnected with the FDPPA-owned
Tyee Lake Project located near Wrangell. The FDPPA is developing a proposed coordinated
Renewable Energy Fund
Grant Application
AEA 09-004 Grant Application Page 16 of 18 9/3/2008
operations plan for the Swan and Tyee projects.
The Four Dam Pool Power Agency (FDPPA) is in the process of ‘Restructuring’. Under this
planned restructuring of the Agency, the Terror Lake and Solomon Gulch projects will be sold or
transferred to Kodiak Electric Association and Copper Valley Electric Association respectively.
The remaining FDPPA assets will include the Tyee Lake and Swan Lake hydroelectric projects
and the associated transmission lines delivering power and energy to Petersburg, Wrangell and
Ketchikan. The Swan-Tyee Intertie, which will interconnect the Tyee Lake and Swan Lake
projects and is currently under construction, will also be owned by the Agency. The Agency
name will be changed from ‘The Four Dam Pool Power Agency’ to ‘Southeast Alaska Power
Agency’. The legal entity, which is a Joint Action Agency organized under State statute, will
remain the same. KPU will be a member of SEAPA, but will continue to operate the electric
distribution system to provide service to Ketchikan’s customers.
4.4.6 Analysis and Recommendations
Provide information about the economic analysis and the proposed project. Discuss your
recommendation for additional project development work.
KPU’s diesel generation will cost approximately 22¢/kWh. Absent grant funding, the estimated
cost of power from the Whitman Lake Project is approximately 13¢/kWh, with grant funding the
cost of power is approximately 4¢/kWh. Whitman Lake will provide KPU and other utilities in the
Southeast region with long-term sustainable environmentally clean energy.
