INTRODUCTION
This report has had various publishers. Before 1985, the federal Alaska Power Administration published
Alaska Electric Power Statistics. Then, the Alaska Energy Authority (formerly the Alaska Power Authority)
began gathering statistical data and publishing this annual report. In 1988, the Alaska Electric Power
Statistics report became a combined effort of the Alaska Systems Coordinating Council and the Alaska
Energy Authority. Beginning in 1993, the report became a joint effort of the Alaska Systems Coordinating
Council and the Alaska Department of Community and Regional Affairs, Division of Energy. After the
1995 report, no reports were issued until 2003, when the Institute of Social and Economic Research
(ISER) at the University of Alaska Anchorage (UAA), published a report, with funding from the Alaska
Energy Authority (AEA), the Regulatory Commission of Alaska (RCA), and the Denali Commission.
ISER prepared this twenty-fourth edition of the Alaska Electric Energy Statistics in collaboration with the
Alaska Energy Authority. Unlike previous reports, data tables are presented solely in digital form in an
MS Excel file. The workbook containing the data tables is available on the ISER website at
httiser.uaa.alaska.edu Publications AlaskaEner StatisticsCY2009Tables.xlsr ) and the AEA website
(http://www.akenergyauthority.org/).The data tables are presented in a dataset format for convenient
use and manipulation. All data presented are identified by the geographic regions used in previous
Alaska Electric Energy Statistics,' as well as AEA energy regions, Alaska Native corporation regions, and
census areas. The data tables available in the workbook are:

The report provides a brief introduction, highlights, and summary tables only. The summary tables use
the AEA Energy Pathway publication regions. There are several appendixes. Appendix A is a glossary of
terms; B has maps showing the energy regions; C lists data sources; and D cites reporting requirements.
The 2008 edition, published in May 2011, includes tables reporting military and industrial generation.
This 2009 report does not contain that information, because not all data are currently available. We
gathered information on utility electricity capacity, generation, and other characteristics from reports
filed with the U.S. Department of Energy's Energy Information Administration (EIA) and made available
on the agency's website; from data collected by the Alaska Energy Authority through the Power Cost
Equalization (PCE) program; and from a limited number of direct contacts with electric power producers.
This is a similar methodology used to develop information for the 2003 and 2008 reports.
All utilities with installed capacity greater than one megawatt are required by law to report their
operations to the federal government. A number of utilities in Alaska fall below that threshold.
Information for these smaller utilities came primarily from the PCE program. The installed capacity table
(Table 2.1a in the Excel workbook) includes all utilities for which data are available. Also, in many parts
of the state, there are no utilities producing electricity, and all electricity is self -generated at small
installations. There are a large number of such installations (for example, Point Baker, Port Protection,
and Telida); it would be very expensive to identify and contact each one individually.
Keep in mind that this publication is meant as a general reference and broad overview of electric power
in Alaska. Because data come from various sources and have imperfections, the reader may find
inconsistencies across tables. For example, Table 2.5b shows average rate per kilowatt-hour as
calculated using the reported revenue, sales, and customers; Table 2.5c shows average rate per kilowatt
hour as reported by the utility to the PCE program; these two rates are sometimes slightly different.'
Data in different tables may include different cases, or may be guided by slightly different concept
definitions, depending on the source. Still, we believe the information presented provides a reasonable
and valuable overview of electric power and energy across Alaska.
z Only for PCE communities. Communities for which the data source is EIA report the same calculated rate as in
Table 2.5b.

SUMMARY AND HIGHLIGHTS
The purpose of this report is to present electric power reference data for Alaska; it is not intended to
provide detailed analysis of energy production, consumption or uses. Nevertheless, this section
highlights information that may be of particular interest to the reader.

Electricity Generation and Cost
• As of 2009, Alaska had about 2,178 megawatts of utility installed capacity that generated about
6.4 million megawatt -hours of electricity.
• Electricity generated by natural gas statewide decreased from 61% in 2008 to 55% in 2009. The
share from hydroelectric power increased from 17% in 2008 to 20% in 2009; generation from oil
products increased from 16% to 18%; and the share from coal increased from 6% to 7%.
Generation from wind remained less than 1%, at about 0.14% statewide.
• Sources of power generation vary sharply by region. The Railbelt region has most of the state's
population and uses most —about 80%—of the electricity. Natural gas is used to generate most
of the electricity for the Railbelt, but the region also has hydropower.
• Many but not all communities in Southeast Alaska get electricity from hydropower; some rely on
diesel.
• Rural communities in Western and Interior Alaska rely mostly on diesel to generate electricity,
but wind power is being added in a growing number of rural places, financed largely by the
state's Renewable Energy Fund. About 80% of wind -power capacity has been added since 2008,
and the amount of electricity generated by wind annually increased almost three -fold in 2009.
• Wood generated heat in 2009 in community -level thermal facilities in about ten communities,
mostly in Southeast, where wood resources are abundant.
• The average annual residential use of electricity statewide in 2009 was about 7,660 kilowatt-
hours —but that ranged from around 1,500 kilowatt-hours in places where electricity is most
expensive to more than 15,000 where it is cheapest. Nationwide, average annual use is about
11,000 kilowatt-hours.

Communities in Southeast Alaska that rely primarily on hydroelectric power to generate
electricity have the lowest rates —as little as 9 cents per kilowatt-hour in 2009. Residents of
Anchorage and other places in Southcentral Alaska that rely mostly on natural gas for
generation paid around 15 cents per kilowatt-hour in 2009. Alaskans in small remote rural
places that rely on diesel have the most expensive electricity —from roughly 50 cents per
kilowatt-hour to more than $1 in 2009. The state helps reduce the price of electricity in most of
those remote rural communities through its Power Cost Equalization program, but electric bills
still remain much higher in remote rural areas than in urban communities.

Compared with 2008, the 2009 installed capacity was stable, without significant growth. The
exception was wind installed capacity, which almost tripled —from 2,174 kW in 2008 to 7,884
kW in 2009. But wind still accounts for less than half of one percent of the total installed
capacity in Alaska. In 2009:
• Railbelt hydroelectric installed capacity was 13% of the Railbelt total
• Hydroelectric installed capacity was 20% of the statewide total
Railbelt total installed capacity was 65% of the statewide total

Compared with 2008, total net generation in 2009 remained stable without significant change,
except for power generated by wind, which tripled from 2,246 MWh in 2008 to 9,152 MWh in
2009. But wind accounts for less than half of one percent of total power generation in the state.
• Railbelt hydroelectric generation in 2009 was 9% of the Railbelt total,
increasing from 7% in 2008.
• Hydroelectric generation was 20% of the statewide total, increasing from

The fossil fuel most used for electricity generation in Alaska is natural gas, though it is only
available in the Railbelt and some communities on the North Slope. Natural gas accounted for
66% of fossil fuels consumed by utilities for power generation in 2009. Diesel is the second
most used fossil fuel for power generation, but it accounts for only 20% of fuel used statewide.
The Railbelt region consumed most —about 59%—of the diesel utilities used for power
generation in 2009, mostly for stand-by units. The Lower Yukon-Kuskokwim region was next,
using about 8% of the diesel consumed statewide. Coal made up 14% of the fossil fuels used in
2009; it is used only in the Railbelt region, specifically in the Fairbanks area, where there is a
convenient local supply. In 2009, burning from all fossil fuels used for generating power
produced about 3.8 million metric tons of carbon dioxide statewide.

Compared with 2008, electricity sales were relatively unchanged in 2009. Sales across energy
regions also changed little. As expected, most of the power sales were in the Railbelt region.
The Southeast and Railbelt regions had the highest annual average use per residential
customer, at about 9,890 kWh and 7832 kWh, respectively. The Yukon-Koyukuk/Upper Tanana
and Bristol Bay regions had the lowest annual average use per residential customer, at about
3,805 kWh and 4,718 kWh, respectively.
Most of the electricity produced in Alaska, about 64%, is sold to commercial customers. The
North Slope and Railbelt regions had the highest annual average use per commercial customer,
at about 129,557 kWh and 106,499 kWh, respectively. The Yukon-Koyukuk/Upper Tanana and
Lower Yukon-Kuskokwim regions had the lowest annual average use per commercial customer,
at about 13,081 kWh and 21,462 kWh, respectively.
3 Other includes sales to community, governmental facilities and others.

Compared with 2008, revenue from electricity sales increased about two percentage points.
Distribution of revenues across energy regions saw no significant change. The Northwest Arctic
region had the highest average revenue per residential customer in 2009, at about $3,817;
followed by the Lower Yukon-Kuskokwim region, which averaged about $2,864. The North
Slope region had the lowest average revenue per residential customer, at about $1,063,
followed by the Southeast region, which averaged about $1,190.Overall 57% of the revenues
from electricity sales came from the commercial sector, because of that sector's higher use
(64% of sales, Table 1e).

As expected, the regions with the most customer accounts were the Railbelt and Southeast. All
other regions accounted for only 13% of total power customers. There were no significant
changes in the number of customer accounts, or regional distribution, between 2008 and 2009.
Residential accounts made up most of the power customers in the state in 2009, about 83%.

Appendix A. Glossary of Terms4
Alaska Energy Authority (AEA): A public corporation of the state with a separate and
independent legal existence with the mission to construct, finance, and operate power projects
and facilities that utilize Alaska's natural resources to produce electricity and heat.
Auxiliary Generator: A generator at the electric plant site that provides power for the
operation of the electrical generating equipment itself, including related demands such as plant
lighting, during periods when the electric plant is not operating and power is unavailable from
the grid. A black start generator used to start main central station generators is considered to
be an auxiliary generator.
Backup (Standby) Generator: A generator that is used only for test purposes, or in the event of
an emergency, such as a shortage of power needed to meet customer load requirements.
Barrel (bbl): A unit of volume equal to 42 U.S. gallons.
Bituminous coal: A dense coal, usually black, sometimes dark brown, often with well-defined
bands of bright and dull material, used primarily as fuel in steam -electric power generation,
with substantial quantities also used for heat and power applications in manufacturing and to
make coke. Bituminous coal is the most abundant coal in active U.S. mining regions. Its
moisture content usually is less than 20%. The heat content of bituminous coal ranges from 21
to 30 million BTU per ton on a moist, mineral -matter -free basis. The heat content of
bituminous coal consumed in the United States averages 24 million BTU per ton, on the as -
received basis (i.e. containing both inherent moisture and mineral matter).
British Thermal Unit: The British thermal unit (BTU or Btu) is a traditional unit of energy equal
to about 1.06 kilojoules. It is approximately the amount of energy needed to heat 1 pound
(0.454 kg) of waterl 'F (0.556 °C). It is used in the power, steam generation, heating and air
conditioning industries. In North America, the term "BTU" is used to describe the heat value
(energy content) of fuels, and also to describe the power of heating and cooling systems. When
used as a unit of power, BTU per hour (BTU/h) is the correct unit, though this is often
abbreviated to just "BTU".
Capital Cost: The cost of field development, plant construction, and the equipment required for
industry operations.

prepared for the Alaska Energy Authority, September 2011
18
Climate Change: A term used to refer to all forms of climatic inconsistency, but especially to
significant change from one prevailing climatic condition to another. In some cases, "climate
change" has been used synonymously with the term "global warming"; scientists, however,
tend to use the term in a wider sense inclusive of natural changes in climate, including climatic
cooling.
Coal: A readily combustible black or brownish -black rock whose composition, including inherent
moisture, consists of more than 50% by weight and more than 70% by volume of carbonaceous
material. It is formed from plant remains that have been compacted, hardened, chemically
altered, and metamorphosed by heat and pressure over geologic time. It is estimated that
Alaska holds about 15% of the world's coal resources, amounting to 170 billion identified short
tons. Major coal provinces include Northern Alaska, the Nenana area, Cook Inlet — Matanuska
Valley, the Alaska Peninsula, and in the Gulf of Alaska and the Bering River. Alaska coals exhibit
low metallic trace elements, good ash -fusion characteristics, and low nitrogen content making
them favorable for meeting environmental constraints on combustion in power plants.
Cogeneration system: A system using a common energy source to produce both electricity and
thermal energy for other uses, resulting in increased fuel efficiency.
Combined Cycle: An electric generating technology in which electricity is produced from
otherwise lost waste heat exiting from one or more gas (combustion) turbines. The exiting heat
is routed to a conventional boiler or to a heat recovery steam generator for utilization by a
steam turbine in the production of electricity. This process increases the efficiency of the
electric generating unit.
Combustion: Chemical oxidation accompanied by the generation of light and heat.
Commercial Sector: An energy -consuming sector that consists of service -providing facilities and
equipment of businesses; Federal, State, and local governments; and other private and public
organizations, such as religious, social, or fraternal groups. The commercial sector includes
institutional living quarters. It also includes sewage treatment facilities. Common uses of
energy associated with this sector include space heating, water heating, air conditioning,
lighting, refrigeration, cooking, and running a wide variety of other equipment. Note: This
sector includes generators that produce electricity and/or useful thermal output primarily to
support the activities of the above -mentioned commercial establishments.
Consumer (energy): Any individually metered dwelling, building, establishment, or location.
Diesel #1: Also known as DF1 or Jet A. Diesel #1 is commonly used as heating fuel throughout
most of northern rural AK. Diesel #1 has a lower gel temperature than Diesel #2 which is sold
for heating fuel in warmer climates. Diesel #1 is same fuel the refineries sell as Jet fuel (Jet A),
and in many tank farms it is stored as Jet A until sold as DF1.

prepared for the Alaska Energy Authority, September 2011
19
Diesel #2: Is commonly used throughout the US. In Alaska it is used for marine and highway
diesel as well as heating fuel in warmer regions. Diesel #2 is preferred over #1 where it is warm
enough as it has higher energy content.
Diesel Fuel: A fuel composed of distillates obtained in petroleum refining operation or blends of
such distillates with residual oil used in motor vehicles. The boiling point and specific gravity
are higher for diesel fuels than for gasoline.

computed for each day by subtracting the average of the day's high and low temperatures from
the base temperature (65 degrees), with negative values set equal to zero. Each day's heating
degree days are summed to create a heating degree day measure for a specified reference
period. Heating degree days are used in energy analysis as an indicator of space heating energy
requirements or use.

following types of activity: manufacturing, agriculture, timber harvest and wood processing,
fishing and fish processing, hunting, mining, oil and gas extraction, and construction. Overall
energy use in this sector is largely for process heat and cooling and powering machinery, with
lesser amounts used for facility heating, air conditioning, and lighting. Fossil fuels are also used
as raw material inputs to manufactured products. Note: This sector includes generators that
produce electricity and/or useful thermal output primarily to support the above -mentioned
industrial activities.
Injections: Natural gas injected into storage reservoirs.
Installed Capacity: The maximum theoretical production output of a plant, based either on

Appendix C. Data Sources for Electric Energy Statistics
The primary data source for the electric power statistics are the U.S. Department of Energy
(DOE), Energy Information Administration (EIA) and the Alaska Energy Authority, Power Cost
Equalization program data. Every utility and industrial (including military) electrical generating
facility with a capacity greater than one megawatt is required to report their operating
characteristics to the EIA annually, and in some instances, monthly. This information is
compiled by the EIA and is available for every generating facility on their website:
(http://www.eia.doe.gov/). We obtained data for the year 2009. The forms of interest to
compile this publication are the EIA 860, 861 and 923. These are reporting forms for capacity,
generation, sales and revenues.
The use of the EIA database is a continuation of the methodology used in the 2008 and 2003
Alaska Electric Power Statistics update. Before the 2003 update, the report's primary data
source was a questionnaire sent to each Alaska utility and industrial facility. There were several
reasons to use the federal database for this report rather than a survey. First, most utilities and
industrial facilities are required by law to report to the federal government each year on their
activities using the EIA forms. Since this information for each utility is available on the EIA
website, it is redundant to collect the same information through a second questionnaire. It is
also considerably less expensive to collect the data from the EIA website than to collect it
through a mail -out survey. Furthermore, using the EIA data reduces the reporting burden
placed on the utilities and industrial producers of electricity. Finally, respondents are required
by law to report to the EIA and this should make the response rate high. In addition, obtaining
generating characteristics from a single source helps to insure consistency between federal and
state reports.
Nonetheless, using EIA data poses some challenges because not all information reported in this
publication is collected via the EIA forms. First, the smallest utilities with installed capacity less
than one megawatt, are not required to report to EIA and are not included in the EIA database.
Second, not all Alaska generating facilities report as required by law.
Data collected in the forms are available in sets of databases that may present portions of the
data differently. For instance, some data may be available at the utility level only, while other
data may be at the facility and/or generator level. The forms are processed by different
departments within EIA and may have differences in the underlying definition of the data
making reconciliation of the information in the datasets within forms, and across the different
forms sometimes difficult. Finally, the lag time for the availability of the federal data is
approximately two years.
To supplement missing data we used the database for the annual Power Cost Equalization
Reports by the Alaska Energy Authority (AEA). Also, as needed, the Alaska Energy Authority and
ISER supplemented these data sources by contacting utilities directly.
Fay, Gin ny, Alejandra Villa lobos Melendez and Amber Converse, 2011, Alaska Energy Statistics,1960-2009,
prepared for the Alaska Energy Authority, September 2011

These data sources allowed us to collect information for almost all the utilities in the state
without incurring the considerable cost of conducting a complete census of all producers. A
few of the smallest utilities that were not either in the EIA database or the Power Cost
Equalization database did not provide information for this report.
The 2009 Power Cost Equalization data provided data on the generation and sales (residential
and commercial) of all utilities participating in the Power Cost Equalization program, including a
breakdown by community for those utilities that operate in multiple communities, such as
Alaska Village Electric Cooperative (AVEC) and Alaska Power and Telephone (AP&T). The EIA
data for these utilities was in some cases reported only as a total across all communities, and
we used this as control totals. AEA, AVEC, AP&T and NSPL provided helpful assistance in
supplying installed capacity information for each plant not originally included in the PCE
database. In this case we were able to publish information taken directly from the utility
reflecting statistics from each of its serviced communities.
The PCE database contains information collected through AEA's PCE Utility Monthly Report
which PCE participants must file. Utilities also report to the RCA annually for fuel cost
adjustments. Reporting to both entities should be consistent, however discrepancies are not
unusual. These discrepancies may be due to high turnover in small utilities, poor reporting and
limited staff to verify the utilities' self reported data.
In addition, there are data (energy loss, use by facility and energy provided without charges)
that is not included in the PCE report. Because of this, the values found in table 2.2a may not
reflect a summation of all AP&T communities as reported in the PCE report. Rather they reflect
what was reported to the EIA directly as prepared by the utility itself. This same methodology
was implemented in the sales and revenues tables (2.4a) when deemed appropriate. The
intent is to create as comprehensive of a table as possible.
The summary information in the historical tables was calculated from the same sources
mentioned above. Data from these sources was calculated and re -formatted where appropriate
and consolidated into master data files from which all the tables in this report where built.
Inevitably the use of multiple data sources introduces some inconsistencies in reporting.
Notwithstanding, we believe that the Alaska Electric Power Statistics 2010 update report
provides useful information on the state of electric power generation in Alaska.

Appendix D. Reporting Requirements
Energy Information Administration
Every utility facility with a capacity greater than one megawatt (MW) is required to report their
operating characteristics to the US Department of Energy (DOE), Energy Information
Administration (EIA) annually, and in some instances, monthly. This information is compiled by
the EIA and is available for every generating facility on their website (http://www.eia.doe.gov/).
Specific reporting requirements are determined by the Department of Energy but collected,
assembled, and evaluated by the EIA according to the Federal Energy Administration Act of
1974. We obtained data for year 2009. Three EIA forms were used in this report:
EIA-860 Annual Electric Generator Report. This report contains information on capacity

Power Cost Equalization Program and Regulatory Commission of Alaska
Participants of the Power Cost Equalization (PCE) program report to the Regulatory Commission
of Alaska (RCA) for fuel cost adjustments to their rates. The RCA has authority to maintain
accounts and records of public utilities that fall under its jurisdiction, under Alaska Statute
42.05.451. This responsibility allows the Regulatory Commission of Alaska to obtain
information from regulated utilities. Additionally, all utilities that serve ten or more customers
must obtain an operating certificate, which describes the authorized service area and scope of
operations of the utility. The RCA will issue a certificate when it finds the utility to be fit,
willing, and able to provide the service. The RCA maintains a list of both regulated and
unregulated certified utilities. Utilities report annually to the RCA, but file a PCE Utility Monthly
Report with AEA.
