Introduction

This report is part of an ongoing effort led by the Alaska Energy Authority (AEA) to identify energy projects that

will reduce the long-term cost of energy in Alaska.

The work presented here can be considered a companion to the Southeast Alaska Integrated Resource Plan (SE

IRP), which was completed in 2012 by a team led by the engineering firm Black and Veatch.0F

1 The SE IRP

employed modeling and other efforts to assess the potential of various ways to lower the cost of energy in

Southeast Alaska, including transmission, generation, energy efficiency, space heating, and demand side

management projects. This document does not replicate or update these cost-benefit studies.

This report serves as a resource for ongoing energy planning in Southeast Alaska. It provides an overview of

the current energy situation through a set of community energy profiles, as well as a discussion of recent

developments and efforts in the region. Feedback was solicited from community and utility leaders, though

additional input is needed. This is a living document that can serve as a template for the region to revise and

keep current as projects, programs, and events change.

Planning Area

The planning area for this project encompasses over 20 communities stretched along the coast of southeast

Alaska from Yakutat to Metlakatla. The area represents AEA’s Southeast energy region.

A number of small and large energy users are not covered in this document. Industrial developments located

outside community electric grids, such as the Kensington Mine and the cannery in Excursion Inlet, are not

included in this report as relevant energy data is not readily available. In addition, a variety of small communities

in the region are excluded due to a limited population and the lack of a central electric utility. The community

of Hyder, Alaska is not covered as it is served by low cost Canadian hydropower from nearby Stewart, British

Columbia.

Electricity

A mix of private and publically-owned utilities

provide electric service to over 41,000 residential,

commercial, and industrial customers in Southeast

Alaska. Most of these utilities serve a single

community, though interconnected grids exist on

Prince of Wales Island, connecting Skagway and

the Haines area, and connecting Petersburg,

Wrangell, Ketchikan, and Saxman. Juneau’s Alaska

Electric Light and Power (AEL&P) accounts for

nearly half (48.2 percent) of all electric sales in the

region, followed by utilities in Ketchikan (20.3

percent), Sitka (12.8 percent), and other

communities.

Southeast Alaska is blessed with abundant rainfall

and mountainous terrain; as a result, over ninety-

five percent of the electricity produced in the

region is derived from hydropower.

While the more populated communities in the

region are supplied by hydropower, many of the

villages and remote areas still rely on diesel for

electrical generation. In addition, newly

constructed hydro projects typically carry substantial debt, adding considerable cost to electric rates.

The region’s utilities are described in more detail below.

Alaska Electric Light & Power (AEL&P)

AEL&P is an investor-owned electric utility serving the city of Juneau, Douglas, and Auke Bay. In addition to

serving retail customers, AEL&P has interruptible Power Sales Agreements with Princess Cruise Lines and the

Greens Creek Mine. Both of these customers own and maintain their own diesel generation for periods when

AEL&P cannot serve them with hydroelectric power.

AEL&P owns and operates hydroelectric resources at Gold Creek, Salmon Creek, Annex Creek, and Lake

Dorothy. The Snettisham hydroelectric project – which accounts for roughly three-quarters of Juneau area

hydro capacity – was built by the federal government but sold to the Alaska Industrial Development and Export

Authority (AIDEA) in 1998. AEL&P buys power from Snettisham through a lease agreement under which the

company is also responsible for maintenance of the project.

AEL&P maintains a number of fossil fuel-fired generators that are used as backup when Snettisham is offline.

These include five slow speed diesel engines at the Gold Creek plant, nine Electro Motive Division diesel engines

and two gas turbines at the Lemon Creek plant, and a Solar Centaur Gas Turbine that runs on either diesel or

natural gas in Auke Bay.

Southeast Alaska Power Agency (SEAPA)

The Southeast Alaska Power Agency (SEAPA) is a regional Joint Action Agency of the State of Alaska that owns

the Swan Lake and Tyee Lake hydroelectric facilities. SEAPA provides power via 14 miles of submarine and 175

miles of overhead transmission lines to the municipalities of Ketchikan, Wrangell, and Petersburg.

Approximately 62 percent of the total power consumed by these three communities is supplied by SEAPA.

Ketchikan Public Utilities (KPU)

KPU is owned by the City of Ketchikan and provides power to customers throughout the Ketchikan Gateway

Borough, including to the nearby community of Saxman.

KPU owns and operates the Ketchikan Lakes, Whitman Lake, and Beaver Falls hydro projects. KPU also operates

SEAPA’s Swan Lake Hydro Project. Ketchikan receives surplus energy (when available and as needed) via

SEAPA's Swan Tyee transmission line, which connects the community to Wrangell and Petersburg's electrical

grids.

Ketchikan's total hydro capacity is approximately 34 MW, including both KPU and SEAPA-owned projects. KPU

maintains four peaking/stand-by diesel generators at Bailey Powerhouse totaling 24 MW, and two other diesel

generators at the North Point Higgins Substation totaling 3.2 MW. The diesel generators provide power to the

community in times of low reservoir levels, hydro maintenance periods, and for emergency use during outages.

KPU's infrastructure includes seven distribution substations, 30-miles of 34.5 kV sub-transmission lines, nearly

100-miles of 12.47 kV distribution lines, and nearly 7,700 electric meters.


Petersburg Municipal Power & Light (PMP&L)

PMP&L is a municipally-owned electric utility providing electric service to approximately 2,000 customers on

Mitkof Island. The utility’s primary source of electrical energy is SEAPA’s 20 MW Tyee Hydro project. PMP&L

also owns, operates, and maintains the 2 MW Blind Slough Hydro project. The utility also has a stand-by 10

MW diesel generation plant sufficient to meet the electrical demand in the event of an outage.

Wrangell Municipal Light & Power (WML&P)

WML&P is a municipally-owned utility providing electric service to approximately 1,800 customers in the

Wrangell area. WML&P obtains the majority of its power through SEAPA from the Tyee Hydro Project, but also

owns and operates an 8.5 MW diesel plant for backup power needs. Wrangell’s distribution system consists of

21.3 miles of overhead distribution and 1 mile of underground distribution at 7.2 kV.

Alaska Power and Telephone (AP&T)

AP&T is a diversified investor-owned utility serving several communities in Southeast Alaska through its wholly-

owned energy subsidiaries, Alaska Power Company, BBL Hydro, Inc., and Goat Lake Hydro, Inc. AP&T’s service

territory in Southeast Alaska is divided into four areas – Prince of Wales Island, Lynn Canal, Whale Pass, and

Gustavus.

AP&T owns and operates hydroelectric facilities at Dewey Lake, Falls Creek, Goat Lake, Kasidaya Creek, Lutak,

Black Bear, and South Fork. AP&T also owns and operates diesel units to supplement its hydroelectric

generation.

PRINCE OF WALES ISLAND (POW)

AP&T serves most communities on Prince of Wales Island in Southeast Alaska, including Coffman Cove, Craig,

Hollis, Hydaburg, Kasaan, Klawock, Naukati, Thorne Bay, and Whale Pass. All of the communities, except Whale

Pass, are interconnected and receive hydro power from Black Bear Lake and South Fork. In partnership with

Haida Corporation, AP&T is currently completing construction of the Hiilangaay Hydro project – formerly

known as Reynolds Creek Hydro – that will add additional hydro capacity to the POW grid. AP&T is working

with Whale Pass to develop a small hydro resource at Neck Lake.

HAINES-SKAGWAY

AP&T serves the Haines-Skagway area with hydro power from Goat Lake, Dewey Lakes, Kasidaya, and Lutak

projects. AP&T also sells excess hydropower to IPEC to serve loads in Chilkat Valley and Klukwan. The majority

of hydropower is produced in Skagway and delivered to Haines via an underwater transmission cable. The

utility and Haines have explored the development of resources in Haines to prevent diesel dependency in the

event of a failure of the undersea cable.

GUSTAVUS

In 2015, AP&T purchased the Gustavus Electric Company, which was formed in 1983 to provide electric service

to the community of Gustavus. AP&T operates the 800 kW Falls Creek run-of-river hydroelectric project, which

was completed in 2009. An underground transmission cable runs five miles from the Falls Creek powerhouse


to the town’s diesel plant. The diesel units provide power during periods of low flows in Falls Creek. A

transmission line connection from Gustavus to Glacier Bay National Park headquarters in nearby Bartlett Cove

is currently in the planning stages.

Inside Passage Electric Cooperative (IPEC)

IPEC is a non-profit, member-owned electric cooperative. IPEC operates in five service areas – Angoon, Kake,

Hoonah, Klukwan, and Chilkat Valley. IPEC operates diesel generating units in all areas except Klukwan, owns

and operates the 10-Mile hydro project near Haines, and purchases additional hydroelectric power from AP&T

to serve the Klukwan/Chilkat Valley area. In 2015, IPEC completed construction of a run-of-river hydro project

on Gartina Creek near Hoonah, which supplies roughly a third of the town’s electrical needs when in operation.

IPEC has plans for a second hydro plant in Hoonah and is designing a small run-of-river hydro project at Gunnuk

Creek in Kake. Angoon’s Kootznoowoo Corporation is finalizing a feasibility study on a proposed hydro plant

at Thayer Creek that is envisioned to supply all of Angoon’s energy needs.

Metlakatla Power & Light (MPL)

MPL owns and operates the Purple Lake and Chester Lake hydroelectric plants. Purple Lake has three 1956-era

Francis type turbine-generators. Chester Lake has a single Pelton type turbine-generator. MPL also owns and

operates the Centennial Power Plant. The Centennial Power Plant consists of a 3.3 MW Caterpillar 3612 diesel

fired engine-generator and a 1 MW battery energy storage system.

A feasibility study is being finalized on the Triangle Lake watershed which could be the next increment of hydro

constructed in the MPL area. Construction funds are being sought for an intertie to the KPU and SEAPA grid

that would allow any surplus electricity to be sold into that grid, if needed, and would provide a source of

electricity for “dry years” in Metlakatla when hydro resources would otherwise be supplemented with diesel-

generated electricity.

City and Borough of Sitka

Sitka owns Blue Lake and Green Lake hydroelectric plants. Sitka generates nearly all of its electric requirements

from these hydroelectric plants. Sitka also owns and operates a diesel plant for backup power needs. The

diesel plant consists of a single Caterpillar diesel fired engine-generator (4.8 MW) and three Fairbanks Morse

generators (7.5 MW total). The City and Borough of Sitka recently completed a major expansion to the Blue

Lake Hydro project, raising the dam by 83 feet and constructing a new powerhouse with three new turbines.

Other Southeast Utilities

YAKUTAT POWER

Yakutat generates all of its electric requirements from diesel engines at the Yakutat Power Plant. The diesel

plant consists of four Caterpillar diesel fired engine-generators.


ELFIN COVE

Electricity for Elfin Cove is provided by the Elfin Cove Utility Commission with diesel generation. The community

has a hydro project in design and is seeking construction funding.

PELICAN

Electricity for Pelican is provided by the Pelican Utility Company from a run-of-river hydro project that was

recently renovated after a major flood event in 2009. The hydro project became operational in 2013 and can

power the entire community when river flows are sufficient. The community also maintains five diesel units for

supplemental and backup power.

TENAKEE SPRINGS

Electricity for Tenakee Springs is provided by the City-owned utility with diesel generation. The city has

completed design and is currently pursuing construction funding for a proposed run-of-river hydro project on

nearby Indian River.

Electrical Rates and Power Cost Equalization

Residential electricity rates vary dramatically across Southeast Alaska. Larger towns – including Sitka, Juneau,

Ketchikan, Petersburg, and Wrangell – enjoy rates of $0.10 to $0.13/kWh. On the other hand, Southeast

Alaska’s smaller communities see much higher rates, ranging from $0.26/kWh in AP&T communities to

$0.75/kWh in Elfin Cove.

For eligible towns with high electric rates, the state’s Power Cost Equalization (PCE) program cuts the effective

rate of the first 500 kWh of monthly residential use substantially. Community facilities are also eligible for the

PCE program. PCE payments totaled $3.4 million for Southeast Alaska during the 2015 fiscal year. Of the total

828 million kWh sold in Southeast Alaska in that year, 3.1 percent was subsidized by the PCE program.

Hydropower

A total of 26 hydroelectric projects, with a combined capacity of 223.4 MW, provide power to Southeast

residents. These include 15 storage projects (those that include a substantial reservoir) and 11 run-of-river

projects (those without a substantial reservoir where production is dependent on river flows).

Monthly production and other data are available from the U.S. Energy Information Administration for

hydroelectric plants with a capacity of 1MW or greater. Figure 4 shows the combined monthly production

from such Southeast hydro projects from 2001 through 2014. Overall, as shown by the dotted trend line, the

region has seen increased production during this time period – largely due to the construction of new hydro

projects such as Kasidaya, South Fork, and Lake Dorothy. Production in 2014 totaled 775 GWh, a 20 percent

increase over the 644 GWh produced in 2001.

Another trend visible in Figure 4 is an increase in seasonal variability of generation. The difference between

winter peak months and summer low months ranged from 17-20 GWh during the period 2001 through 2006.

From 2007 through 2014, this difference increased to an average of 40.5 GWh, with major implications for

hydropower supplied utilities. The variability decreased in 2014 to a total difference of 30GWh, and reports

from utility managers indicate that similarly lower levels of variability were seen in 2015.

Projects Under Development

A variety of hydroelectric projects are currently under development in Southeast Alaska. Of the projects listed

in Table 2 below, the most advanced are the Hiilangaay Hydro project – formerly known as Reynolds Creek

Hydro – and the Swan Lake Expansion, both of which are currently under construction.

Gunnuk Creek Hydro is a top priority for the community of Kake and the project proponent, Inside Passage

Electric Cooperative (IPEC). IPEC is currently completing the final design and permitting stages of this project

and raising funds for construction. Similarly, the small communities of Elfin Cove and Tenakee Springs are both

pursuing final design and construction funds for the Crooked Creek/Jim’s Lake and Indian River hydro projects.

Juneau Hydropower Incorporated is championing the Sweetheart Creek Hydro project, aiming to sell power

into the Juneau electrical grid and possibly to the Kensington mine. The Southeast Alaska Power Agency is

currently studying hydro and other resources to determine the next increments of electrical generation to be

added to the SEAPA grid.

Diesel Power

Efficiency

More than 1.26 million gallons of diesel fuel are used annually to generate electricity in Southeast Alaska’s PCE-

eligible communities. Diesel plants in Southeast Alaska’s PCE-eligible communities vary in efficiency, as shown

in Figure 5. AEA has set a performance benchmark of 12.5 kWh per gallon for small utilities (those generating

under 2,000 MWh per year) and 14.5 kWh per gallon for larger utilities. All of Southeast Alaska’s PCE

communities meet this target except Kake, Elfin Cove, Whale Pass, and Naukati.

In recognition of the challenge of operating efficient small diesel generation and transmission systems in rural

Alaska, the Alaska Energy Authority created the Rural Power System Upgrade (RPSU) program. The RPSU

program provides resources to address the following:

Fuel Prices

Based on PCE data for FY2015, diesel prices paid by Southeast Alaska’s PCE-eligible utilities ranged from $4.68

per gallon in Elfin Cove to $3.53 per gallon in Yakutat. The weighted average across these communities was

$3.65 per gallon during the year. Larger communities that primarily rely on hydropower are not included here,

and are generally able to purchase diesel at significantly lower rates.

Bulk Fuel Storage Issues

Storage of diesel and other fuels used in Southeast communities can be an issue as tanks age, pipes corrode,

and spills and leaks become more likely. The Alaska Energy Authority’s Bulk Fuel Upgrade (BFU) program, with

substantial contributions from the Denali Commission, funds assessments and construction of code-compliant

rural bulk fuel facilities. As shown in the table below, seven Southeast communities have received upgrades

through this program, with another two in progress and eight remaining.

Heat Recovery from Diesel Plants

Roughly half of the communities that run diesel generators regularly have installed and use heat recovery

systems to take advantage of the waste heat created during the process of electricity generation. The

communities with heat recovery, and the buildings heated, are listed in Table 5 below. Heat recovery projects

in these communities have generally been funded and completed through the Alaska Energy Authority’s Rural

Power System Upgrade or Renewable Energy Fund programs. Communities not using heat recovery include

some, such as Kake, that lack a suitable space heating load in close proximity to the diesel plant.

Other Renewable Energy Developments

Currently, all electricity generated by utilities in Southeast Alaska is derived from diesel generators or

conventional hydropower. However, a variety of other energy sources have been considered in the region,

including wind, wave, solar, tidal, biomass, and geothermal. For more detail on this subject, see Chapter 11 of

the SE IRP (Volume II).

Southeast Alaska’s population grew at a rate of 3.8 percent from 2010 to 2015. A lower level of growth (2.29

percent) is expected from 2015 to 2035, according to projections published by the Alaska Department of Labor

and Workforce Development, Research and Analysis Section. The state agency’s projections are based on aging

forward current demographic groups, combined with estimates of projected births, death, and in/out

migration.

Subregions within Southeast Alaska are projected to grow at substantially different rates. From 2010 to 2015,

the fastest growing areas in the region were the City and Borough of Juneau (6.4 percent growth) and the

Municipality of Skagway Borough (7.4 percent). These areas are also expected to grow the fastest from 2015

to 2035. On the other side of the spectrum, the City and Borough of Yakutat and the Petersburg Borough are

expected to experience a population decline of over 10 percent from 2015 to 2035.

Trends in Average Customer Use

Electric sales at Southeast’s utilities split into three categories, residential (38 percent of all sales), commercial

(36 percent) and industrial (26 percent). Residential sales include those to private households and apartment

buildings. Commercial sales include sales to nonmanufacturing businesses; health, social, and education

institutions; governmental entities; and street lighting. Industrial sales are described in more detail below.

Average monthly sales per residential and commercial customer are presented below for each utility grid in

Southeast Alaska for 2010 through 2014. Trends over this time period can be a result of energy efficiency

measures, variation in heating needs, and many other factors. It is important to note that differences between

communities in average monthly usage per customer is partly a factor of the number of seasonal residents in

each community, as well as other factors.

Trends in Industrial Sales

Industrial sales refer to sales to businesses in the manufacturing, construction, mining, agriculture, fishing, and

forestry sectors. Four utilities in Southeast Alaska reported sales to industrial customers in 2014, totaling

197,502 GWh. The largest utility in the region, AEL&P, sells power to industrial customers on an interruptible

basis and trends in those sales depend more on excess hydropower capacity than industrial activity. Important

customers for AEL&P include the Greens Creek Mine and Princess Cruises (shoreside power for one cruise ship

berth). Another major industrial customer is the Vigor Shipyard served by Ketchikan Public Utilities.

Load Forecasting

The SE IRP produced a series of load forecasts for Southeast Alaska’s utility grids for the period 2011 through

2061, including a reference scenario (business-as-usual), a high scenario (assuming market penetration of

electric vehicles and high economic growth and development), and a low scenario (aggressive implementation

of the demand side management, energy efficiency, and heating conversion recommendations in the SE IRP).

The charts below show the SE IRP forecasts (in GWh) for each utility grid for the period 2011-2035. Where

data was available, actual production for 2011-2014 is also provided. In the end, it is up to local community

and utility leaders to plan for future electrical generation needs based on the best available information. Such

planning is especially important as hydro and other generation projects can take many years to permit, finance,

and construct.

Mining loads that could impact electrical needs in the region include several mines in the advanced exploration

stage, including Bokan Mountain (~10-20 MW required) and Niblack (~10MW) on POW and the Constantine-

Palmer Project near Haines (~10MW). In addition, there is the potential to serve the Kensington Mine

(~10MW), which is currently uses diesel generation to power its ongoing operation near Juneau. Capacity

requirement estimates are from the SE IRP, which includes additional discussion of this topic.

Energy Efficiency/Demand Side Management

The 2012 SE IRP evaluated a suite of demand side management and energy efficiency (DSM/EE) options with

the potential to provide energy cost savings and peak load reductions. These options were compared to

alternative supply-side options. The result was a recommendation to aggressively pursue DSM/EE programs,

including investments in weatherization, promotion of energy efficient appliances and technologies, conversion

of space heating equipment away from heating fuel, and other measures.

Below is an update on recent progress on DSM/EE and weatherization efforts in Southeast Alaska. Space heating

technologies and conversions are discussed in the following section of this report.

Residential

Overall, it is estimated that slightly more than a quarter (27 percent) of Southeast Alaska’s occupied housing

units have been retrofitted through weatherization, new construction, and retrofit programs. Community

specific estimates are also provided in the community energy profiles section of this report.

The majority of the retrofits described above were completed through Alaska Housing Finance Corporation

(AHFC) programs, including the home energy rebate, weatherization, and new home rebate programs. The

home energy rebate program, which has been paused due to lack of funding as of April 2016, provided rebates

of up to $10,000 for completion of energy improvements (weatherization, replacement of inefficient heating

appliances, etc.) in private residences.

The weatherization program provides energy improvements at no-cost for qualifying low-income residents,

using a network of weatherization service providers. Providers in Southeast Alaska include RurAL CAP (Juneau),

Alaska Community Development Corporation (outside Juneau), Baranof Island Housing Authority (Sitka),

Ketchikan Indian Community Housing Authority (Ketchikan), and Tlingit-Haida Regional Housing Authority

(majority of Southeast communities, including Juneau).

Southeast Alaska’s regional housing authorities (RHAs) create and upgrade affordable housing to provide home

ownership and rental opportunities. RHAs are the primary source of new and renovated housing options in

many of the region’s communities, and build all new housing to the Alaska Building Energy Efficiency Standard

(BEES). Funding for RHA programs comes from a variety of sources including the U.S. Housing and Urban

Development’s NAHASDA program and AHFC Supplemental Housing Development grants.

The largest RHA in Southeast Alaska is the Tlingit-Haida Regional Housing Authority (THRHA). THRHA recently

completed a major DOE-funded study of energy efficiency and alternative energy opportunities at THRHA-

owned multifamily residential buildings.1F

2 Many of THRHA’s properties are located in the region’s high energy

cost communities.

Recent energy efficiency improvements at THRHA buildings include a major retrofit and expansion of the Kake

Senior center, an effort that included weatherization, addition of new propane and wood pellet boilers, and

energy monitoring, among other measures. Solar photovoltaic panels are also being installed at the Kake Senior

Center and will be studied to evaluate their potential at other sites in Southeast Alaska.

In Angoon, THRHA is planning a major upgrade to 9 multi-family residential units, including weatherization

and a district heating loop powered by a pellet fired boiler (replacing 22 oil-fired boilers). In 2017, the THRHA

is also planning to weatherize and upgrade their 12-unit low rent building in Haines, and is considering wood

heat, heat pumps, and other options. The housing authority has also evaluated solar hot water systems for its

senior centers and other buildings but did not find them to be cost-effective.

Commercial and Public Buildings

It is estimated that more than half of the building energy use in Alaska is consumed by nonresidential buildings.

Organized efforts to improve the energy efficiency of these buildings has received attention in recent years,

starting with a Commercial Building Energy Audit Program through the Alaska Energy Authority. This program

is not currently accepting applications, though similar efforts are being pursued through a partnership between

Southeast Conference, Renewable Energy Alaska Project, and the Sustainable Southeast Partnership, with

funding from all three organizations as well as AHFC and a USDA grant.

In 2015, the coalition described above completed Level I energy audits of 34 public and private buildings in

Southeast Alaska with a combined total of more than 230,000 square feet of space. Of these, 9 were located

in Haines, 11 in Hoonah, 6 in Klawock, and 8 in Craig. Efforts also included completing an inventory of

commercial and public buildings in each of these communities. Participation is being solicited for a Round II

effort in 2017 that will include up to 26 additional energy audits at commercial and public buildings in

Southeast Alaska.

Community Wide Efforts

The U.S. Department of Energy’s (DOE) Office of Indian Energy manages a competitive energy assistance

program called Strategic Technical Assistance Response Team (START). START assists in the development of

tribal renewable energy and energy efficiency projects in rural Alaska Native communities. Three Southeast

Alaska communities have been selected for START assistance in recent years – Kake, Yakutat, and Hoonah.

In Kake, START efforts included the completion of a community energy plan, as well as technical assistance to

move various community energy projects forward. In Yakutat, investment grade energy audits were completed

at public and commercial buildings including the community center, Kwan plaza and the Yakutat clinic, and

Yakutat Seafood Incorporated’s warehouse, fish processing facility, ice house, and bunkhouse. Retrofits were

completed at the community center and Kwan plaza/Yakutat clinic. Efforts in Hoonah are currently ongoing

and include strategic planning and a focus on assisting community efforts to build a biomass district heating

system.

The DOE is also currently implementing the Remote Alaska Communities Energy Efficiency (RACEE)

competition. The RACEE program invites eligible Alaskan communities and native villages (those a population

under 8,000) to sign a pledge to improve community energy efficiency by 15 percent or more by 2020.


Those communities who sign this pledge are identified as Community Efficiency Champions and are eligible to

compete for funds to implement energy saving measures. Throughout Alaska 64 communities signed this

pledge, including Yakutat, Haines, Pelican, Angoon, Kake, Kasaan, Saxman, and Klawock in Southeast. In April

2016, 13 Alaska communities were selected to receive in-kind technical assistance through the Phase II of the

RACEE program, including the Village of Klawock. Phase II communities are eligible to apply for DOE grant

funding in Phase III of the RACEE program, with applications due in August 2016.

Other Demand Side Management/Energy Efficiency Efforts

The Alaska Energy Authority’s akenergyefficiency.org website, a project of the Alaska Energy Efficiency

Partnership, provides a wide variety of resources and energy savings tips covering residential, commercial, and

public buildings. A list of energy audit professionals, including ratings of their performance and contact

information, and a calendar of events, trainings, and workshops is also provided at the site. Other Alaska Energy

Authority education efforts include offering a tool kit for loan to Alaskans to assess energy efficiency

opportunities. The tool kit can include watt meters, light meters, ballast checkers, and occupancy and other

sensors and loggers.

Notable utility and community-led energy efficiency efforts in recent years include numerous projects to

upgrade street lighting to LED and improve the energy efficiency of water and wastewater systems. Some of

these efforts are reflected in the community energy profiles provided in this report. Unfortunately, responses

were limited and comprehensive information on street lighting and water/wastewater energy efficiency efforts

was not available at the time of publication of this report.

Space Heating

Space heating costs represent a major portion of

residential, commercial, and industrial energy

expenditures in Southeast Alaska. However, limited data

is available to measure the amount and types of energy

consumed for space heating in the region.

The Alaska Housing Finance Corporation’s (AHFC) 2014

Housing Needs Assessment provides an estimate of

energy use for space heating, based on data from the

state’s weatherization and energy retrofit programs,

energy consumption at AHFC properties, and modeling.

The 2014 Housing Needs Assessment estimates that fuel

oil accounts for close to three quarters of total residential

space heating energy in Southeast Alaska, followed by

wood, electricity, and propane (Figure 7). It is important

to note, however, that a large portion of homes in

Southeast Alaska have the ability to use more than one

fuel type for space heating, and will adjust as prices

change.

Community buildings in Southeast Alaska follow roughly

the same pattern of space heating fuel use. The 2014

Housing Needs Assessment estimates that roughly 75

percent of space heating energy for the region’s

community buildings derives from fuel oil, followed by

14 percent from wood, 9 percent from electricity, and 2

percent from propane.

This section describes additional data sources available for specific communities and fuel types. Trends, such

as increased utilization of electric heat in hydro-supplied towns and addition of a variety of biomass projects in

public buildings thorough the region, are explored.

Fuel Oil

Oil has traditionally been the main fuel for space heating in the Southeast. Generally, two forms of oil space

heating are used, oil-fired boilers and Monitor or Toyo stoves. Relatively little data is available regarding the

amount of oil used for space heating in the region, as most fuel oil suppliers view such data as confidential.

Using a variety of assumptions, the 2012 SE IRP estimated that roughly 17.4 million gallons of fuel oil were

burned in 2012 for space heating in Southeast Alaska, at a total cost of $72 million dollars or over $1,000 per

person. Estimates by community are provided in the table below.

Fuel oil expenditures also have the downside of being subject to wide swings in price based on global oil

markets. Figure 8 below shows the range of prices in ten Southeast Alaska communities from 2005 through

2016. Prices jumped in 2008 and again in 2011, only recently returning to 2005/2006 levels.

In general, prices can be as much as $1-$2 more per gallon in the region’s smaller, more isolated communities.

While fuel oil prices are set at the global level, the cost of barge transportation to smaller markets adds

substantially to the final price. Smaller communities generally do not purchase enough to qualify for bulk

purchase discounts and coordination between purchasers in a town (generally the fuel depot and the local

utility) can be challenged by cash flow alignment issues. Other factors affecting fuel price include the distance


from major linehaul routes, safety and ease of offloading at docks, and the number of vendors serving the

community.

Biomass

Biomass refers to organic material such as cordwood, wood chips, wood pellets, municipal waste, and fish by-

products. Southeast Alaska communities are surrounded by the nation’s largest national forest, the 17 million

acre Tongass National Forest. While wood heat has long played an important role, the high cost of fuel oil and

technology improvements have driven an increased interest in woody biomass projects in recent years.

At least 19 non-residential biomass projects have been completed in Southeast Alaska in the last decade, with

additional projects under construction and others in design. These estimates come from the Alaska Wood

Energy Development Task Group, a coalition of 20 federal and state agencies and organizations working to

increase the utilization of wood for energy and biofuels production in Alaska.2F

3 The Task Force has helped fund

pre-feasibility studies and spearheaded efforts to disseminate information on high-efficiency, low-emission,

wood-fired systems that work in Alaska.

The projects described above utilize a variety of fuel types – including wood pellets, wood chips, and cordwood.

Each of these types offer certain advantages and certain disadvantages. The main factors that vary are price,

ease of use, availability, and cost of conversion, as shown in Table 12 below.

WOOD PELLETS

One of the key benefits driving the use of fuel oil and electricity for space heating is convenience. Of the

biomass fuel options available, wood pellets are considered the easiest to use, as they can be delivered by

trucks, filling hoppers that automatically feed pellet boilers with minimal maintenance required.

For residential applications, wood pellets are available for purchase in Southeast Alaska’s larger towns in 40

pound bags at various hardware stores. In addition, bulk deliveries can be supplied by road and ferry from

Juneau and Ketchikan. Sealaska Corporation owns a truck in Juneau and currently supplies pellets at a cost of

$375 per ton (not including delivery charges) to projects in Juneau and Haines. Tongass Forest Enterprises in

Ketchikan – currently the only wood pellet manufacturer in Southeast Alaska – sells its pellets for $275-350 per

ton and delivers them to projects in Ketchikan as well as by ferry to Kake.

The 2012 Southeast IRP estimated that for pellets at $300 per ton, the break-even price of oil is approximately

$2.70 per gallon. In 2014, a federal official estimated the cost of pellets used at the Ketchikan Federal Building

equated to a fuel oil price of roughly $2.15 per gallon.

WOOD CHIPS

Wood chips offer many of the benefits of wood pellets in that the fuel and can be loaded in bulk and the boiler

systems can operate autonomously like pellet and oil boilers. Typically, a chip boiler requires a more robust

fuel handling and feed system due to the fact that chips don’t ‘flow’ like pellets.

Currently, the only major wood chip-fueled biomass project in Southeast (a complex of two schools and a pool

in Craig) sources its chips from the Viking Lumber and Milling sawmill in Klawock on Prince of Wales Island.

The Haines school and pool project currently under development is planned for chips sourced from the nearby

Haines State Forest.

A key advantage of chips over pellets is that they can be produced in the local community with relatively simple

and inexpensive equipment. Chips can be expected in the $70 per ton range, which would equate to heating

oil at less than one dollar per gallon. The Forest Service is developing a ‘Local Chips’ production program that

will provide detailed guidance on how a community can establish its own chip production program.

CORDWOOD

Cordwood systems can be an excellent solution for remote, high-energy-cost communities, and are rapidly

being adopted throughout Alaska. In general, heating oil needs to be under $1.50 per gallon to compete with

cordwood systems on an energy cost basis. Numerous schools on Prince of Wales have converted to cordwood

systems, where the boilers heat the schools as well as adjacent school greenhouses. These systems provide

many additional benefits including, enhanced learning opportunities in science, horticultural math and

business, and community food security. The Alaska Energy Authority, with funding from the U.S. Forest Service,

is currently developing a biomass greenhouse handbook based on success stories in Southeast and Interior

Alaska.

Cordwood offers an important advantage over pellets or chips in that it can be produced with minimal tools

(chainsaw and a truck) and using skills already present in every forested Alaska community. Supply has not

been an issue in the communities where cordwood systems have been installed.


In addition to often being lower in price compared to fuel oil, other benefits of all three types of biomass fuel

include increased price stability, as the market is not subject to the wild swings seen in the global oil market.

An increase in energy expenditures remaining in the Southeast economy, rather than being spent to purchase

imported fossil fuels, also creates local jobs and strengthens the Southeast Alaska’s economy.

On the other hand, biomass systems typically require an increased time commitment to handle fuel and oversee

boiler operations, as well as increased capital costs compared to other options. When considering a biomass

system, careful consideration needs to be made as to whether the disadvantages outweigh the benefits. Despite

these challenges, the cost savings and demonstrated community interest suggests that continued growth of

the biomass space heating sector can be expected in Southeast Alaska.

Electric Heat

When oil prices increased significantly in 2008 and again in 2010 and 2011, many customers in areas with low-

cost hydroelectric generation converted to electric resistance heat. These conversions significantly increased

electric loads, consuming excess hydro generation resources and, in some cases, resulted in the operation of

backup diesel generation during low water periods. The significant increase in electric loads also often strains

other parts of the utility system, including transformer capacity.

Relatively little data is available to accurately capture trends in electric heating in Southeast Alaska. The

community of Wrangell adopted a special heat rate in 2006 for residences and 2009 for commercial customers.

The rate, $0.086 per kWh or roughly 2 cents lower than the normal rate, applies only to separately metered

electric heating appliances. Sales through this program (Figure 9) show an increase in consumption in 2008

and again in 2010/2011 – corresponding to peaks in heating oil prices – followed by a leveling off and a slight

decline in sales through the residential program in recent years. In 2015, sales through Wrangell’s heat rate

represented 15 percent of all residential and 25 percent of all commercial sales.

Figure 10. Electricity Sales through Wrangell’s Special Heat Rate, Megawatt Hours, 2007-2015

ELECTRIC RESISTANCE HEATING

The most common types of electric heat in the region are electric boilers and electric baseboards. Electric

boilers can replace oil-fueled boilers, but are more expensive in general than electric baseboards. Portable

electric space heaters are also very inexpensive and commonly used in a supplemental heating role. Commercial

Residential Commercial


businesses are more likely use to an electric boiler, though the penetration of electric heat with commercial

customers is generally quite a bit lower than for residential customers, according to the 2012 Southeast IRP.

HEAT PUMPS

A third, and increasingly popular, electric heating option is a heat pump. The 2012 Southeast IRP described

these systems as follows: “Typical air source heat pump systems lose efficiency rapidly at temperatures below

30˚ F. Heat pump systems that operate in a heating only mode are now being developed that can operate

efficiently down to 0˚ F.”

Since the preparation of the SE IRP, air source heat pump (ASHP) technology has improved and received

widespread attention from heating and air conditioning service providers, consumers, and researchers. A 2013

report by the Cold Climate Housing Research Center (CCHRC) concluded that “ASHPs are appropriate for

consideration in Southeast Alaska because of recent improvements in technology, favorable climatic conditions,

and relatively inexpensive electricity.”3F

4

Relying on interviews with utility managers and others, the CCRC estimated that at least 135 residential and

25 commercial air source heat pump systems had been installed in Southeast Alaska (and 210 throughout the

state) by 2013. Recent research indicates at least 500 air source heat pumps have been installed in Alaska, and

finds that nearly all heat pumps users report satisfaction with their systems.4F

5

Starting in early 2012, the City and Borough of Sitka offered a $1,500 incentive for homeowners heating solely

with electricity to switch to an air source heat pump. A total of 40 rebates were provided over the one-year

life of the program.5F

6 In 2013, Sitka’s utility manager estimated 80 air source heat pumps had been installed in

the community, and that over 90 percent of these were heat pumps designed to heat single rooms, known as

mini-splits.6F

7

AEL&P in Juneau has offered a heat pump rate since the early 1980’s – currently set at $0.051 per kWh and

available to residences that do not use any resistance electric heat. Data provided by the utility indicates that

sales through this program grew 116 percent in the last seven years, from 165 MWh in 2008 to 359 MWh in

2015.

Roughly 20 Juneau households currently utilize AEL&P’s heat pump rate – a fraction of all heat pumps installed

in Juneau. According to a 2016 article in the Capital City Weekly, installers report at least 150 residential air

source heat pumps have been installed in Juneau over the last two years alone. 7F

8 In addition, recent commercial

installations in Juneau include ground source heat pumps at the Dimond Park Aquatic Center, Juneau’s airport

terminal, the Auke Bay School, the Johnson Youth Center, and the Forestry Sciences Laboratory – as well as air

source heat pumps at the IGA Foodland and a sea water heat pump at the Ted Stevens Marine Research

Institute, among others.

Natural Gas

In 2014, Avista Corporation purchased Juneau’s electric utility, AEL&P, and began discussing possible delivery

of natural gas within Southeast Alaska. Avista Corporation, based in Spokane, Washington, currently serves

roughly 369,000 electric customers and 329,000 natural gas customers in Washington, Oregon, and Idaho.

The corporation has proposed shipping liquefied natural gas (LNG) to Southeast Alaska, primarily to serve

heating loads in the Juneau area, but also to replace diesel fuel used to generate electricity at major industrial

customers, small communities throughout the region, and in Juneau. AEL&P is currently installing a backup

generator capable of running on diesel or natural gas; it is expected to come online in Fall 2016.

Natural gas is currently quite a bit cheaper per unit of thermal energy than diesel fuel on global markets, though

the price spread between these two commodities has declined in recent years. Delivered costs of natural gas

would also depend on LNG capacity, shipping costs, economies of scale, and permitting issues. LNG would be

regasified in Juneau and delivered via a system of pipelines built out over time to buildings throughout the

town’s major population centers. The potential rate of conversion to natural gas by Juneau’s residential and

commercial space heating consumers is a major factor in the economies of scale available to this effort.

Avista’s proposal has the potential to bring considerable savings and economic development to Juneau and

Southeast Alaska. Based on market conditions in the Fall of 2014, McDowell Group estimated economic impacts

in Juneau alone would include $5-15 million in annual savings for space heating consumers, creation of 60-180

new jobs as a result of these savings, and dozens of construction jobs (90 in year 1 of build out, followed by 20

jobs in years 2-10).8F

9

In September 2015, Avista officials indicated that natural gas shipments to Juneau would originate in British

Columbia.

Efforts to develop Alaska’s natural gas resources are a major focus for the State of Alaska. The Alaska Legislature

directed the Alaska Energy Authority to prepare a plan and recommendations on infrastructure needed to

deliver affordable energy to areas of the state that will not have direct access to the proposed North Slope

natural gas pipeline. This effort is known as the Alaska Affordable Energy Strategy (AkAES), and includes a study

of the viability of shipping LNG to the other parts of the state. Results and recommendations from the AkAES

are required to be delivered to the legislature no later than January 1, 2017.

Community Energy Profiles

The following two-part profiles provide a snapshot of each community in Southeast Alaska (excluding the

smallest communities that lack a central electric utility).

A community profile provides a very brief overview of each town, including type of local government, date

incorporated, location, economy, historical and cultural resources, demographics, and key contacts. These

overview profiles are intended to provide context and not to provide a comprehensive description of each

community. This is a template offered to communities, and the region, to be kept current during ongoing

planning efforts.

Additionally, an energy profile provides available electricity production and sales data, along with information

on fuel prices, a partial inventory of non-residential buildings in the community, participation in state and

federal energy efficiency programs, and a mention of key energy projects going on or recently completed in

each community.

Though based on the latest available data from state and federal sources, not all information is accurate due to

sampling errors and data gaps. Draft versions of the community and energy profiles were emailed to the utility

manager, city clerk/borough manager, and local tribe in each community in May 2016. The profiles in this

report incorporate edits and additional information received. These profiles, and this report in general, should

be considered a work in progress, and would benefit from additional review and input.

Additional Resources

A variety of additional resources are available for energy planning and implementation in Alaska.

The Alaska Energy Authority’s Community Assistance program provides hands-on assistance in developing

energy projects and addressing local issues. In addition, a number of studies are currently ongoing as part of

the the Alaska Affordable Energy Strategy (AkAES). The AkAES is a state-directed effort to help provide

affordable energy to all areas of the state if a natural gas pipeline is built from Alaska’s North Slope. A set of

recommendations will be delivered to the Alaska Legislature in 2017.

In addition to providing valuable information, the AkAES could also provide a future funding mechanism for

energy infrastructure in areas of the state without direct access to a North Slope natural gas pipeline. More

information on the AkAES can be found at: http://www.akenergyauthority.org/Policy/AffordableEnergy.

Another important resource is the U.S. Department of Energy’s (DOE) Office of Indian Energy’s energy

planning handbook.9F

10 Rapid response technical assistance is also available for Alaska Native villages through

the DOE (http://www.nrel.gov/tech_deployment/tech_assistance_tribes.html).

The DOE, Office of Indian Energy recently released a document titled “Sustainable Energy Solutions for

Alaskans” that provides a number of energy recommendations for Alaska’s remote communities.10F

Historical Setting / Cultural Resources Wrangell is one of the oldest non-Native settlements in Alaska, established to support fur trading and later mining up the nearby Stikine River. By 1916, fishing and forest products had become the primary industries. The Alaska Pulp sawmill, Wrangell's largest employer, closed in late 1994.

Economy Tourism and growth in the seafood processing and marine services industries have become the economic backbone.
