INTRODUCTION
This twenty-sixth edition of the Alaska Energy Statistics reconciles energy data from public sources and
makes that data more easily available to the public and stakeholders. It presents 2012 data on electricity
produced by primarily certified utilities in Alaska. It includes a brief introduction, a summary of Alaska’s
energy portfolio, and highlights of changes and trends observed in the year. This report contains only
highlights of the complete information provided in the data tables. The data tables are available for
download at the Alaska Energy Authority (AEA) website. The data tables are also searchable and
selected data may be downloaded at the Alaska Energy Data Gateway (AEDG) database, where other
Alaska data has also been gathered, such as community information and population statistics. Links to
those sources are provided below.
A collection of appendixes define terms, list references, and describes data sources. This report presents
data for the state and for the 11 Alaska Energy Authority energy regions. In the accompanying
workbook, we also present data by U.S. census areas, Alaska Native corporation regions, and regions
used in earlier Alaska Electric Energy Statistics reports.
Purpose
This Alaska Energy Statistics Report is assembled to be a comprehensive and single source of electrical
generation information across Alaska. Two primary sources of energy data are available to the public,
though each is only a partial data set. Larger Alaska electric utilities report to the U.S. Energy
Information Administration, which publishes the data. But the majority of Alaska utilities are under the
size threshold required for reporting to EIA. The Power Cost Equalization program, administered by AEA,
gathers energy data from these smaller utilities. This report combines the two datasets to produce a
statewide electrical generation summary.
This report, and particularly the accompanying workbook and information published in the AEDG
database, is intended for decision makers, project managers, utility managers and others to have access
to statewide energy data to drive policy and project decisions. It also serves as Alaska’s measure of
progress against the goal of 50 percent renewable energy by 2020.
Workbook Contents
The workbook containing detailed data tables is available on the AEA website at
(http://www.akenergyauthority.org/Publications). The data presented in this report are also available
for viewing and downloading through the AEDG (https://akenergygateway.alaska.edu). Refer to
Appendix B for a list of all data tables available in the MS Excel workbook.
Energy Regions
Figure 1 on the following page shows the areas of Alaska that fall within each of the Alaska Energy
Authority’s eleven energy regions.

HIGHLIGHTS AND SUMMARY
This report features information that may be of general interest on electricity produced primarily by
certified utilities in Alaska in 2012. The report is not intended to provide detailed analysis of energy
production and consumption or to make suggestions about how Alaska should manage its energy
portfolio. The detailed data sets of the information summarized here are available on the AEA website
(http://www.akenergyauthority.org/Publications).
Table 1 provides an overview of generation, capacity, and population within each energy region and
statewide.

One of the most fundamental characteristics of Alaska is that the vast majority of the state’s population
and energy activity is concentrated in one region known as the Railbelt. This region generally comprises
the areas surrounding the Alaska Railroad including Fairbanks, Anchorage, Homer and all of the
communities in between. The Southeast region, which includes the capitol city of Juneau, has the
second largest concentration of the state’s population. Accordingly, most of Alaska’s energy is produced
and consumed in these regions. In 2012, only about 11% of statewide net generation occurred in the
other nine regions.
Compared to 2011, total installed capacity increased by 2.7% and total net generation increased by
1.9%. This change occurred at the same time that statewide population increased by 1.1%.

Installed Capacity
Table 2 lists the inventories of installed capacity within each energy region by prime mover. In 2012 the
state had a total installed capacity of nearly 2.3 gigawatts. Over 57% of that capacity is from turbines
which are located mostly in the Railbelt. The most prevalent type of capacity in the rest of the state is
internal combustion totaling to just over 20%. Hydroelectric power makes up another 20% of capacity
and is located in regions where the resource is available.

The year 2012 saw about a 3% gain (60.3 MW) in statewide installed capacity from the previous year.
The most significant regional gains were realized in the Kodiak region which saw a 7% increase in total
capacity. This change was a result of Kodiak Electric Association doubling their capacity at the Pillar
Mountain wind farm.
Several regions completed construction of new wind capacity in the year with installed capacity
increasing by an astonishing 375% statewide. The most notable regional gains were an additional 100%
in Kodiak, 250% in Northwest Arctic, 400% in Bristol Bay, and over 4200% in the Railbelt.

The state generated a total of 6,679 gigawatt-hours from all sources. Just over half of that electricity was
generated with natural gas in the North Slope and Railbelt regions- currently the only regions with
ample access to this resource. Almost another quarter was generated at hydroelectric facilities across
the state. Coal, constituting 6% of all net generation, is used for generation only in the Railbelt region
where a large coal mine ships the fuel up and down the rail line. The statewide distribution of
generation by fuel type is illustrated in Figure 2.

Total net generation gained modestly from 2011 with an increase of 1.9% (126.9 GWh). The only fuel
type with reduced generation in 2012 was natural gas at a loss of about 8%. Correspondingly, the
Railbelt was the only region with a decrease, generating about 1% less electricity. Hydroelectric and
wind total generation experienced considerable growth with gains of 23% and 173% respectively.
Electricity Sales and Consumption
Table 4 shows electricity sales in megawatt-hours within each region of the state. The table also
delineates sales by customer class. Residential sales constituted 34% at a total of 2,160 gigawatt-hours.
Nearly 44% of gigawatt-hours were sold to commercial customers with a total of 2,769. Other sales
made up 22% of statewide sales with a total of 1,428 gigawatt-hours. All electricity sales within the state
in the year 2012 summed to 6,356 gigawatt-hours.

Table 5 uses data from communities participating in the Power Cost Equalization program in 2012 to
show minimum, maximum, and mean of community average residential electricity consumption at a
range of effective rates.1 PCE only applies to the first 500 kilowatt-hours of residential electricity
consumed per household so there is a strong incentive for customers to keep their monthly
consumption below that threshold, particularly in communities with higher rates. The far right column in
the table shows the percentage of kilowatt-hours that were eligible for PCE according to this and other
criteria. The table also breaks out these measures into semiannual seasons to illustrate the changes in
consumption due to the changes in temperature, daylight, and price variability associated with winter.
1 The effective rate is simply the pre-PCE residential rate less the PCE level in a particular community.

Note: All averages are weighted. Percentages of residential consumption may seem
lower than expected because some communities eligible to receive PCE participated in
the program for only a portion of the year. If during a given month a utility did not
participate and did not receive a PCE payment, then its eligible PCE consumption is 0% of
sales for that month.
In nearly every case, an increase in the effective rate is associated with a decrease in consumption. The
percentage of kilowatt-hours consumed that were eligible for PCE was as low as 69% in the summer and
60% in the winter. At the higher end of effective rates, the maximum eligibility rates ranged from 100%
in the summer to 87% in the winter.
Electricity Prices and Revenues
Table 6 shows the weighted average price components for a range of effective rates in PCE
communities. The average residential rate in PCE eligible communities equaled 50 cents per kilowatt-
hour in 2012. The same measure including all communities in the state averaged at 18 cents per
kilowatt-hour.

Total number of communities does not match the total in Table 9 because one
community participating in the PCE program did not report residential rate data.
Table 7 provides revenues from each of the recorded customer classes to all certified utilities by energy
region. The share of revenues in the Railbelt is considerably lower than the share of sales in the Railbelt
simply because those utilities can sell electricity at lower rates. The same is true for Southeast, though
to a lesser extent.

13 March 2015
The year 2012 saw a statewide revenue increase of 3.3% in the residential class and 10% in the other
class while commercial revenues remained nearly flat. Outside of the Railbelt, however, all but one
region actually saw gains in commercial revenues. The most notable increases were in the Aleutians
(17.4%), Bristol Bay (17.1%), Lower Yukon-Kuskokwim (22.2%), and Yukon-Koyukuk/Upper Tanana
(36.7%) regions.
Generation Fuel
Most communities in Alaska still rely, at least partially, on fossil fuels for electricity generation. Outside
of the North Slope and Railbelt regions, fuel oil is the only utilized generation fuel source. In 2012,
natural gas was the most prevalent fuel source statewide. By energy content, gas constituted 68% of all
fuel burned. This was followed by oil at 18% and coal at 14% of fuel used in 2012.

2 Utilities in Alaska use a variety of fuel oil types including distillate fuel oil, jet fuel, residual fuel oil, naphtha, and
heavy atmospheric gas oil (HAGO). Each type of fuel has different characteristics and Btu content; all these fuels
are included here under the label “oil.” For detailed information, please refer to Table 2.3c—Generation, Fuel Use,
Fuel Cost and Efficiency—in the workbook accompanying this publication.
3 Thermal conversion factors can be used to estimate the heat content in British thermal units (Btu) of a given
amount of energy measured in physical units. The conversion factors shown correspond to the average Btu
content in barrels of petroleum fuel (oil), Mcf of natural gas, and short tons of coal, respectively, as published by
the U.S. Energy Information Administration.
AEA | 2012 Alaska Energy Statistics Report
14 March 2015
In 2012, statewide use of oil and coal for electricity generation increased by about 7% each. At the same
time, natural gas usage decreased by 5%. Two oil-dependent regions significantly decreased their use in
2012. Kodiak consumed 65% less oil than in 2011 and Southeast oil usage declined by nearly 24%.
Power Cost Equalization
The PCE program provides economic assistance to communities throughout the state by subsidizing
their local electricity rates, so long as they are eligible and active. Community eligibility for PCE is mostly
contingent on whether or not a community benefits from any of a number of major energy investments
that the State of Alaska made in the Railbelt and Southeast regions. Community activity requires utilities
to regularly report a number of statistics concerning power production and distribution and to submit all
residential and community facility bills for the calculated reimbursement.

Note: Some utilities, in both urban and rural Alaska, serve multiple communities. Please refer to the
“Community List” table in the accompanying workbook for detailed information about communities served
by each utility.
In 2012, just over 96% of all PCE eligible communities were active in the program. Regionally, this
number ranged from 80-100%. There were only small changes to these statistics from 2011 but all
resulted in increases to the corresponding regional activity in the program.
Figure 4 illustrates the PCE and effective rates of every PCE community that was active in the program.
The weighted average PCE reimbursement rate in eligible communities equaled 29 cents per kilowatt-
hour in 2012. The resulting effective rate equaled an average of 21 cents per kilowatt-hour in the same
year.

Summary
Figure 5 shows the historical net generation of electricity in Alaska from the years 1971 to 2012. In that
time, statewide net generation has increased over six fold from 1,071 to 6,679 gigawatt-hours. This is an
average growth rate of 136.8 gigawatt-hours per year. From 2011 to 2012, the annual change was
slightly lower than that average increasing by 126.9 gigawatt-hours.

In 2009, the State of Alaska established a goal of meeting 50% of electrical demand through renewable
generation sources. At that time, utilities were producing 21.4% of electricity from renewables.4 By
2011, this statistic was nearly unchanged at 20.8%.5 The year 2012 saw major progress towards this goal
with 25.5% of generation coming from renewables. This is nearly a 25% year-to-year increase in the
share.
4 It is important to note that this report only accounts for renewable electricity generated at the utility level. While
many residential, community, commercial, and industrial consumers have installed renewable systems throughout
the state, there is no comprehensive, consistent effort to collect data from these systems.
5 Most renewable energy in the state is generated by hydroelectric sources. As a result, the annual share of
renewable generation is subject to significant natural variation depending on the amount and timing of rain,
snowfall, and snow melt.

APPENDIX A. GLOSSARY OF TERMS6
Alaska Energy Authority (AEA): A public corporation of the state with a separate and independent legal
existence with the mission to reduce the cost of energy in Alaska. http://www.akenergyauthority.org/
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 water1
°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.
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.

Alaska-specific terms.
AEA | 2012 Alaska Energy Statistics Report
18 March 2015
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 a gas turbine in
combination with a steam turbine that uses otherwise lost heat exiting from the gas (combustion)
turbine. 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 a transportation and heating fuel
throughout most of northern rural AK. Diesel #1 has a lower gel temperature than Diesel #2 which is
sold as a transportation and heating fuel in warmer climates.
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 and is typically cheaper.
AEA | 2012 Alaska Energy Statistics Report
19 March 2015

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.
Hydroelectric Power: The use of flowing water to produce electrical energy. Storage hydro, run-of-river

steam engine. The term internal combustion engine usually refers to an engine in which combustion is
intermittent, such as the more familiar four-stroke and two-stroke piston engines. A second class of
internal combustion engines uses continuous combustion: gas turbines, jet engines and most rocket
engines.

APPENDIX E. DATA SOURCES FOR ELECTRIC ENERGY STATISTICS
Information on utility electricity capacity, generation, and other characteristics was gathered from
reports filed with the U.S. Department of Energy’s Energy Information Administration (EIA). The Alaska
Energy Authority collected final EIA data files for the EIA survey forms 860, 861, and 923 for all reporting
utilities in Alaska. Additionally, AEA used data collected by the Power Cost Equalization (PCE) program
and a limited number of direct contacts with electric power producers. AEA also conducted a careful
cross-check of the PCE program data. This report and accompanying tables present all final data.
All producers of electricity with installed capacity greater than one megawatt are required by law to
report their operations to the federal government. Most utilities in Alaska fall below that installed
capacity threshold.7 Information for these smaller utilities came primarily from the PCE program.
In many parts of Alaska there is no utility-produced electricity available, and any activity using electricity
requires self-generation. The number of such small installations (e.g. Point Baker, Port Protection,
Telida) is quite large, though relatively small in terms of installed capacity and net generation. It would
be a very expensive task to identify and contact individually each self-generator. As a result, total
statewide estimates do not include self-generators and are therefore incomplete. In addition to small
communities, there are industrial and military self-generators in Alaska, but few public data are
available for these producers. Hence, data for industrial and military self-generators is included for those
who report publically available data to the Energy Information Administration. The information
presented in this report includes primarily certified public utilities for which public data are available.
It is important to note that this publication is meant to serve as a general reference and broad overview
of electric power in Alaska. Because data come from a variety of sources that have imperfections,
readers may find inconsistencies across tables. For example, Table 2.5b shows average rate per kilowatt-
hour as calculated using reported revenue, sales, and customers, and Table 2.5c shows an imputed
weighted average rate per kilowatt-hour as reported monthly by the utility to the PCE program. These
two rates are sometimes slightly different.8 Data in different tables may include different cases, or may
be guided by slightly different concept definitions, depending on the data source. However, the authors
believe the data presented provide a reasonable and valuable overview of electric power and energy
across Alaska.
Energy Information Administration Surveys
7 Data for approximately 93% of utilities is from the PCE database. (For utilities that manage many isolated
systems, such as the Alaska Village Electric Cooperative (AVEC) and Alaska Power and Telephone Company (AP&T),
each isolated system is counted as a “utility.”) But as this report shows, most generation and electricity and fuel
use are in the urban centers, which are served by larger utilities that do report to EIA. Utilities such as AVEC and
AP&T also report to EIA, though for some variables only aggregated data is reported. In those cases, PCE data
provides community level information.
8 This is only applicable to PCE communities. Communities for which the data source is EIA report the same
calculated rate as in Table 2.5b.
AEA | 2012 Alaska Energy Statistics Report

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/). 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.
Following the methodology established in 2010, we continue to use the EIA database with some
modifications in order to publish this report more timely. Most utilities and industrial facilities are
required by law to report to the federal government each year on their activities using the EIA forms;
this information is then made available on the EIA website. This process causes a delay; the lag time for
the availability of the federal data is approximately two years. However, it is redundant to collect the
same information through a second questionnaire. Respondents are required by law to report to the EIA
and this should make the response rate high. In order to expedite this process, the Alaska Energy
Authority collected copies of the CY2012 EIA forms from a selective group of utilities, and created a
reduced data set. After EIA final data files are published, a cross reference review of the data is done
and a final report is produced.
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.
These forms collect data at different levels of aggregation; for example some at the utility level only,
while other data may be at the facility and/or generator level. This sometime causes 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.
Alaska Energy Authority - Power Cost Equalization Program Data
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.
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 in the EIA database nor in the Power Cost Equalization database were not
included in the data informing this report.
The 2012 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
AEA | 2012 Alaska Energy Statistics Report
34 March 2015
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 these as control totals.
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 PCE 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 2012 Alaska Energy Statistics Report provides useful information
on the state of electric power generation in Alaska.

APPENDIX F. 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 2012.
Three EIA forms were used in this report:
EIA-860 Annual Electric Generator Report. This report contains information on capacity and
types of fuel used. It is completed by all existing plants and proposed (5-year plans) plants that:
1) have a total generator nameplate capacity (sum for all generators at a single site) of one
megawatt or greater; and 2) where the plant is connected to the local or regional electric power
grid and has the ability to draw power from the grid or deliver power to the grid.
EIA -860M Monthly Update to the Annual Electric Generator Report. This report contains
monthly updates to the EIA-860. It is completed by those who also completed EIA-860 and
additionally indicated a proposed change in generator production within one month of the
report period. The proposed change may be due to: 1) a new generator scheduled to start
commercial operation; 2) an existing generator scheduled to retire from service; or 3) an
existing generator with a proposed modification scheduled.
EIA-861 Annual Electric Power Industry Report. This report contains information on peak
production, net generation, sales, and revenues. It is completed by electric industry distributors
including: electric utilities, wholesale power marketers (registered with the Federal Energy
Regulatory Commission), energy service providers (registered with the Regulatory Commission
of Alaska), and electric power producers.
EIA-923 Power Plant Operations Report. This report contains information on electric power
generation, fuel consumption, fossil fuel stocks, and fossil fuel cost and quality. It is completed
by all electric power plants that: 1) have a total generator nameplate capacity (sum for
generators at a single site) of one megawatt or greater; and 2) where the plant is connected to
the local or regional electric power grid and has the ability to draw power from the grid or
deliver power to the grid.
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 and non-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
AEA | 2012 Alaska Energy Statistics Report
36 March 2015
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, and file a
PCE Utility Monthly Report with AEA.
