can provide energy at a known cost that
can hedge against volatile fuel prices and
dampen the effects of infl ation. With some of
the best renewable energy resources in the
country, Alaska has an opportunity to invest
locally in sustainable infrastructure, saving
communities millions of dollars in energy
costs each year. As concerns about fossil fuel
prices, energy security and climate change
increase, renewable resources play a key role
in sustaining communities with local, clean
and inexhaustible energy to supply Alaska’s
demand for electricity, heat, and transportation
fuel. Partly due to the challenges associated
with importing and transporting fossil fuels,
more Alaskans are looking to resources like
hydropower, wind, biomass, solar and to a
lesser extent geothermal, tides, and waves
to generate electricity and heat. Alaskans
are also saving heat and electricity through
energy effi ciency and conservation measures,
keeping dollars in their local economy and
creating more stable and resilient communities.
Effi ciency also helps to move toward the state
goal of 50 percent renewable energy by 2025
because energy avoided through effi ciency is
almost always generated using fossil fuels.
The Renewable Energy Atlas of Alaska is
designed as a resource for the public, policy
makers, advocates, landowners, developers,
utility companies and others interested in
furthering the production of electricity, heat
and fuels from hydro, wind, biomass, solar,
geothermal and ocean power resources.
Produced with the use of geographic
information system (GIS) technology, this
Atlas brings together renewable resource
maps and data into a single comprehensive
document. The maps contained in this Atlas
do not eliminate the need for on-site resource
assessment. However, they do provide a high
level estimate of the available resources. The
Atlas is posted on the Alaska Energy Authority
(AEA) website, akenergyauthority.org, and
the Renewable Energy Alaska Project (REAP)
website, alaskarenewableenergy.org.

Renewable Energy Atlas of Alaska2
With 16 percent of the country’s landmass and less
than 0.3 percent of its population, Alaska’s unique
geography has driven development of its energy
supply infrastructure — power plants, power lines,
natural gas pipelines, bulk fuel tank farms and
related facilities. Alaska has more than 150 islanded,
standalone electrical grids serving rural villages, and
larger transmission grids in Southeast Alaska and the
Railbelt. The Railbelt electrical grid stretches from
Fairbanks through Anchorage to the Kenai Peninsula
and provides roughly 79 percent of the state’s
electrical energy.
Powered by wood until 1927, Fairbanks switched to
coal after the railroad provided access to the Nenana
and Healy coalfi elds. The Anchorage and Matanuska-
Susitna Valley areas have enjoyed relatively low-cost
heating and power (by Alaska standards) since the
development of the Eklutna Lake hydropower plant
in the late 1940’s and major Cook Inlet oil and gas
discoveries in the 1960s.
Completed in 1986, the AEA-owned Willow–Healy
Intertie transmission line now carries power from
diverse energy sources to the Fairbanks area.
Nearly 73 percent of the Railbelt’s electricity
comes from natural gas. Major power generation
facilities along the Railbelt include Chugach Electric
Association’s (CEA) 332-MW natural gas-fi red plant
west of Anchorage at Beluga, Anchorage Municipal
Light and Power’s (ML&P) 120 MW natural gas-fi red
Combined Heat and Power plant in Anchorage,
CEA and ML&P’s 204 MW natural gas-fi red power
plant in Anchorage and Golden Valley Electric
Association’s (GVEA) 181 MW facility near Fairbanks
fueled by naphtha from the Trans-Alaska pipeline
system. Homer Electric Association (HEA) has three
natural gas fi red power plants at Nikiski, Soldotna
and Bernice Lake that total 204 MW and Matanuska
Electric Association’s (MEA) 171-MW dual-fuel (gas or
diesel) generation station near Eklutna was added in
2015.
The 126 MW, AEA-owned Bradley Lake hydroelectric
plant near Homer has been a low-cost source of
electricity for the Railbelt since 1991. In 2017,
AEA fi nanced an expansion that will boost annual
production by an estimated 10 percent.
Wind farms have also sprouted up on the Railbelt,
including 17.6 MW on Fire Island near Anchorage,
24.6 MW at Eva Creek near Healy and 1.9 MW at
Delta Junction.
Today, a little less than 2,000 MW of installed power
generation capacity exists along the Railbelt. AEA
and the six Railbelt utilities are currently studying the
benefi ts of coordinating dispatch of power generation
from all sources to maximize effi ciencies and cost-
savings. Investments in the Railbelt’s transmission
system would be required to realize all of those
potential benefi ts.
During the early 1980s, the state completed a total of
four hydropower projects to serve Ketchikan, Kodiak,
Petersburg, Valdez and Wrangell. At
76 MW, the “Four Dam Pool” projects
displace the equivalent of about 20
million gallons of diesel for annual power
production. Additional southeast hydro facilities
are currently being developed in Juneau and Prince
of Wales Island communities.
Southcentral Alaska’s heating needs are met almost
exclusively by ENSTAR Natural Gas Company, which
moves gas from the Cook Inlet gas fi elds through
over 300 miles of pipelines, and a little over 3,000
miles of distribution mains to the Kenai Peninsula,
Anchorage and Matanuska Valley areas.
With some notable exceptions, most of Alaska’s
remaining power and heating needs are fueled
by diesel barged from Lower 48 suppliers or
transported from refi neries in Nikiski, North
Pole and Valdez. After freeze-up, many
remote communities rely on fuel
stored in tank farms,
or pay a premium
for fuel fl own in by air
tankers. State and federal
authorities continue to
support programs to fi x leaky
tanks, improve power generation, generation
effi ciency and develop local renewable energy
sources such as wind, biomass and hydro.

Biomass
Alaska’s primary biomass fuels are wood, sawmill
waste, fi sh byproducts and municipal waste.
Wood remains an important renewable energy source
for Alaskans. More than 100,000 cords of wood are
burned in the form of cordwood, chips and pellets
annually. Wood-heating systems in Alaska are creating
local jobs and reducing the cost of building heat in
remote communities throughout the state.
The closure of major pulp mills in Sitka and Ketchikan
in the 1990s ended large-scale, wood-fi red power
generation in Alaska. However, the price volatility
of oil has raised interest in using sawdust and wood
wastes for lumber drying, space heating and small-
scale power production.
In 2010, Tok School installed a chip-fi red boiler,
displacing approximately 65,000 gallons of fuel
oil annually. Also in 2010, Sealaska Corporation
installed the state’s fi rst large-scale pellet boiler
at its headquarters in Juneau. Since these two
demonstration projects were operational, 50
additional projects have started up in the state using
cordwood, chips and pellet technology. In 2017, the
City of Galena started operating a chip system that is
heating 14 Galena Interior Learning Academy (GILA)
buildings, displacing more than 200,000 gallons of
fuel oil annually. At the end of 2018, the Southeast
Island School District on Prince of Wales Island had
cordwood heating systems installed at all eight of
its schools. Once schools have an affordable source
of heating, they can install greenhouses to grow
food for school cafeterias and to expand math and
science curriculum with hands-on learning. Students
are learning math and chemistry as they grow lettuce
in their school greenhouses, and students are eating
fresh vegetables in their cafeterias.
Interest in manufacturing wood pellets continues to
rise. Currently, there are small and large-scale plants
operating in Alaska. The largest facility, Superior
Pellets, is located in North Pole and is capable of
producing an estimated 30,000 tons of pellets per
year.
Every year, ground fi sh processors in Unalaska, Kodiak
and other locations produce approximately 8 million
gallons of pollock oil as a byproduct of fi shmeal
plants. The oil is used as boiler fuel for drying the
fi shmeal or is exported to Pacifi c Rim markets for
livestock and aquaculture feed supplements and
other uses. In 2001, with assistance from the State of
Alaska, processor UniSea Inc. conducted successful
tests of raw fi sh oil/diesel blends in a 2.2-MW engine
generator. Today, UniSea uses about 1.5 million
gallons of fi sh oil a year to operate its generators,
boilers and fi shmeal dryers.
Many Alaskans use vegetable oils, recycled cooking
oils and other animal fats to manufacture biodiesel
engine fuels. In 2010, Alaska Waste opened the
state’s fi rst large-scale biodiesel refi nery, producing
up to 250,000 gallons annually from local restaurant
vegetable oil waste. Alaska Waste operates 60-70
vehicles in its Anchorage service area fl eet, and at
peak production runs a 10/90 ratio of biodiesel to
regular diesel across their fl eet.
Alaskans generate approximately 650,000 tons
of garbage per year. In 2012, the Municipality of
Anchorage and Doyon Utilities commissioned a
5.6-MW methane power plant at the city’s landfi ll
that provides more than 25 percent of Joint Base
Elmendorf-Richardson’s electrical load.

Alaska has three distinct geothermally active
regions: the Interior hot springs, running from the
Yukon Territory of Canada to the Seward Peninsula;
the Southeast hot springs; and the “Ring of Fire”
volcanoes, which include the Aleutians, the Alaska
Peninsula, the Wrangell Mountains and Mount
Edgecumbe on Kruzof Island.
Use of geothermal resources falls into two categories:
direct use and electricity production. Direct use
includes applications such as district heating,
greenhouses, absorption chilling and swimming pool
heating.
A number of small-scale direct use projects exist
across the state, but even though Alaska has locally
impressive surface expressions of geothermal energy,
attempts to develop Alaska’s geothermal resources
for community-scale power generation have been
unsuccessful to date.
Exploration in the 1980s near Mount Makushin outside
of Dutch Harbor indicated that tens of megawatts
could be generated from geothermal resources
there. Since 2008, several potential geothermal
resources have been explored across Alaska with no
commercially viable resource found. In 2008, the State
awarded geothermal leases to Ormat Technologies,
Inc. for tracts 80 miles west of Anchorage at Mount
Spurr. After extensive investigations and drilling in
2011, Ormat did not encounter temperatures capable
of supporting a power plant. Akutan in the Aleutians
is another potential geothermal site investigated
since 2008. In 2010 and again in 2017, the City of
Akutan drilled exploratory wells in Hot Springs Bay
Valley, encountering shallow, hot water over 350
degrees Fahrenheit, but with fl ow rates insuffi cient for
electricity production.
In 2012, several exploration wells were completed at
Pilgrim Hot Springs on the Seward Peninsula in order
to assess the area’s resource potential, but a suffi cient
resource was not found. A 2011 reconnaissance study
determined that a potential geothermal resource at
Tenakee Inlet Hot Springs in Southeast Alaska was too
remote and uncertain to warrant further exploration.
In the Interior, Chena Hot Springs Resort is an
example of diverse geothermal energy use, providing
heat and power to its facilities, swimming pools and
greenhouses. The resort utilizes organic Rankine cycle
generators with a total capacity of 680 kW that run on
165 degrees Fahrenheit water, the lowest temperature
for an operating geothermal power plant in the world.
In 2005, the resort installed a 16-ton absorption chiller
and uses geothermal energy to keep an outdoor ice
museum frozen year-round.
Ground source heat pump (GSHP) systems
are electrically powered systems that
tap the relatively constant temperature of
surrounding earth or water bodies to provide
heating and cooling. More than 50,000 of
these systems are installed in the U.S. each
year. In Alaska, heat pump systems are used for
space heating homes, commercial buildings and
public facilities. A number of installations exist
across the state, including at the Juneau Airport,
in operation since 2011, and Juneau’s Dimond Park
Aquatic Center. Southeast and Southcentral have
several other installations, including a seawater heat
pump at the Alaska SeaLife Center in Seward. GSHP
systems are most benefi cial in areas with low electric
rates and high heating costs.

Hydroelectric power, Alaska’s largest source of
renewable energy, supplies roughly a quarter of the
state’s electricity in an average water year. In 2018,
50 hydro projects provided power to Alaska utility
customers, including the Alaska Energy Authority-
owned 120-MW Bradley Lake project near Homer,
which supplies nine percent of the Railbelt’s electricity.
Most of the state’s developed hydro resources are
located in Southcentral, the Alaska Peninsula and
Southeast – mountainous regions with moderate
to high precipitation. Outside the Railbelt, major
communities supplied with hydropower are
Glennallen, Haines, Juneau, Ketchikan, Kodiak,
Petersburg, Sitka, Skagway, Wrangell, and Valdez.
The Waterfall Creek Hydro project in King Cove,
commissioned in 2017, is saving the community about
60,000 gallons of diesel per year. Combined with the
community’s fi rst hydro project on Delta Creek, King
Cove is now saving more than 83,000 gallons of diesel
per year and frequently meets their 2 MW demand in
the silence of diesels-off.
In 2014, Kodiak Electric Association installed a third
10-MW turbine at their Terror Lake hydro facility,
increasing powerhouse capacity to 30 MW. This
added capacity enables peak load demands to be
met without operating diesel generators. Terror Lake
also helps to regulate the 9-MW wind farm at Pillar
Mountain allowing Kodiak to meet its power demand
with nearly 100 percent renewable energy.
Other projects provide hydro storage without dam
construction through the natural impoundment of
existing lakes. The 31-MW Crater Lake project, part of
the Snettisham project near Juneau, includes a “lake
tap” near the bottom of the lake that supplies water
to a powerhouse at sea level through a 1.5-mile long
tunnel.
Still other projects increase annual energy production
by diverting rivers to existing hydroelectric storage
reservoirs and power plants. These projects allow
more effi cient use of existing infrastructure, including
intake structures, dams, powerhouses, generation
equipment, roads and transmission lines. Projects like
this include the Stetson Creek diversion to Cooper
Lake near Kenai Lake, West Fork Upper Battle Creek
diversion at Bradley Lake and the Waterfall Creek
project at King Cove.
Smaller, “run-of-river” projects use more modest
structures to divert a portion of the natural river fl ow
through penstocks to turbines making power. The
824-kW Tazimina project near Iliamna diverts water
into an intake 250 feet upstream from a 100-foot
waterfall through a steel penstock to an underground
powerhouse, and then releases it back into the river
near the base of the falls. Other run-of-river projects
include Falls Creek at Gustavus and Chuniisax Creek
in Atka. Projects at Packers Creek in Chignik Lagoon
and Gartina Falls near Hoonah have recently been
completed.
In 2011, AEA began pursuing an original Federal
Energy Regulatory Commission (FERC) license
for the proposed Susitna-Watana Hydroelectric
Project located at river mile 184 on the Susitna
River. The proposed project consisted of a
705-foot-high dam, constructed using the roller
compacted concrete methodology, with an installed
capacity of 459 MW, capable of providing 2.8 million
MWh of energy annually (half the Railbelt’s average
annual electric load). AEA completed the engineering
feasibility report and benefi t-cost and economic
impact analysis, investigated fi nancing models,
developed a robust FERC-approved study plan and
conducted many of the approved environmental
studies. Due to the state’s fi scal situation, the State
of Alaska requested the licensing process be put
into abeyance following FERC’s issuance of an
updated Study Plan Determination on all of the
work completed through 2015. AEA has completed
approximately two-thirds of the work necessary to
prepare a FERC license application. The study effort
has provided volumes of information and data about
the Susitna basin, the indigenous cultures, fi sheries,
wildlife and landscape. The data and reports are
publicaly available online through AEA, Alaska
Resources Library and Information Services and
Geographic Information Network of Alaska.

Alaska has thousands of miles of coastline, providing
potential for tidal and wave energy development.
Alaska rivers can also be a potential resource; river
in-stream and tidal energy technologies could supply
some of Alaska’s energy needs.
Tidal and river in-stream energy can be extracted
using hydrokinetic devices. These devices are
placed directly into a river or tidal current and are
powered by the kinetic energy of moving water. The
available power is a function of the water current’s
speed and the swept area. In contrast, traditional
hydropower uses a diversion structure or a dam to
supply a combination of hydraulic head and water
volume to a turbine generating power. Hydrokinetic
devices require a minimum current and water depth
to operate. Speeds of 2-4 knots are the minimum
speed required, while 5-7 knots provide for optimum
operation. Ideal locations for hydrokinetic devices
are those with signifi cant fl ow throughout the year
and that are not susceptible to serious fl ood events,
turbulence, debris or extended periods of low water.
Tidal energy is a concentrated form of the
gravitational energy exerted by the moon and, to a
lesser extent, the sun. Cook Inlet, with North America’s
second-largest tidal range, has attracted interest
as an energy source for the Railbelt. To quantify
this, in 2013, National Oceanic and Atmospheric
Administration (NOAA) partnered with the Alaska
Energy Authority to create a model of Cook Inlet’s
tidal energy potential. Between 2005 and 2016, state
and federal funding was invested to study potential
tidal power sites at Cairn Point, Fire Island and
the East Foreland in Cook Inlet; Cordova; and
Isanotski Strait near False Pass. Although no
commercially viable opportunity has been
discovered, the possibility remains for
technological advances to someday
allow us to capitalize on tidal
energy in Alaska.
Wave energy is the result of wind acting on the
ocean surface. Alaska has one of the strongest wave
resources in the world, with parts of the Aleutian
Islands coast averaging more than 50 kW per meter
of wave front. The challenge is lack of energy demand
near the resource, the lack of commercially available
generators and the high cost of pre-commercial
systems. Much of Alaska’s wave energy is dissipated
on remote, undeveloped shorelines. Other substantial
wave energy areas include the southern side of
the Alaska Peninsula and coastlines of Kodiak and
Southeast Alaska.
Many rural Alaska communities situated along
navigable waterways have the potential to host river
in-stream hydrokinetic installations. The University of
Alaska completed a statewide assessment of in-stream
hydrokinetic potential in rural Alaska in 2011.
Hydrokinetic systems have been tested
in pilot studies in the Yukon River near
Ruby and Eagle, in the Tanana River
near Nenana and in the Kvichak River
near Igiugig.
In 2019, FERC issued a pilot license to the
Igiugig Village Council for deployment of the fi rst
commercial production unit of the RivGen Power
System ®, a hydrokinetic power system designed
by Ocean Renewable Power Company. Given
the velocity of the Kvichak River near Igiugig,
the turbine is expected to generate 35 kW.
The system will be deployed year-round,
and is expected to displace approximately
50 percent of the diesel the community has
been burning to generate electricity.
While there are clearly many opportunities, signifi cant
environmental, economic and technical challenges
remain for the widespread commercial deployment
of wave, tidal and in-river devices. However,
these technologies are evolving and are being
demonstrated at more sites around the
world each year.

Alaska’s high latitude presents the challenge of having
minimal solar energy during long winter months when
energy demand is greatest. At the same time, solar
generation in the shoulder months (spring and fall)
is often impressive in northern latitudes where clear
skies, cool temperatures, dry air and bright, refl ective
snow all support solar generation: Solar photovoltaic
(PV) systems can actually exceed their rated output
during these times of year.
Strong competition and advances in the solar
panel technology sector have led to a 70 percent
decrease in the national average cost of solar PV
installations since 2010. In 2018, more than 250,000
people worked in the solar industry in the U.S., more
than double the number in 2012. Decreasing cost
continues to drive consumer interest and the industry
throughout the country.
As with all intermittent renewable energy, integrating
solar into the type of small, islanded grids that exist in
most rural communities in Alaska can be challenging
if not properly planned and managed. For projects
that are not being developed by the local utility, it is
critical that developers work closely with the utility to
ensure proper integration into the local grid. Off-grid
applications such as remote fi sh camps, lodges and
cabins, can be ideal applications for solar PV.
The Native Village of Hughes recently installed a
120 kW solar photovoltaic system. The project is
being developed to help advance the community’s
renewable energy goal of 50 percent by 2025. When
the project is completed it will be the largest solar
project in a small rural community in the state.
On the Railbelt two noteworthy projects were
added in 2018, the fi rst is a 563-kW project owned
by Golden Valley Electric Association located in
Fairbanks. The project is the largest solar project in
the state and is operated by the utility and owned
by all cooperative members as a whole. The other is
100 kW solar fi eld was built along the Parks Highway
in Willow and a second phase adding generation
capacity is planned for 2019. This Railbelt project sells
power to Matanuska Electric Association at wholesale
rates.
In larger systems, such as the Railbelt energy region
which serves most of urban Alaska, there are rules
governing distributed generation, and the potential
to negatively impact the entire system is of less of
a concern. As the cost of solar PV comes down it
becomes a more attractive option for homeowners
and business owners. In Anchorage, for instance,
the Solarize Anchorage campaign helped put 150
systems on rooftops across the city between 2017 and
2018, and work is continuing. Federal tax incentives,
paired with the economy of scale provided by the
Solarize Anchorage campaign, has motivated a
historic number of Anchorage residents to
invest in rooftop solar. This trend is consistent
with consumer interest elsewhere in the
country, and is expected to continue growing
throughout the state.
“Solar thermal” heating systems use pumps
or fans to move energy to a point of use, such as a
domestic hot water tank. Typical homes demand a
large amount of fuel year-round for domestic hot
water, so using the sun to heat water for even seven
or eight months a year can save signifi cant amounts
of energy. A larger role for solar thermal hot water
systems in Alaska is emerging as heating systems
advance – allowing solar-heated fl uid to supply in-
fl oor systems currently heated by fuel boilers.
In Alaska, careful building design and construction
can minimize the use of heating fuel. “Passive solar”
design includes proper southern orientation and the
use of south-facing windows that transfer the sun’s
energy into the building through natural processes of
conduction, convection and radiation. Passive solar
design employs windows, thermal mass and proper
insulation to enable the building itself to function as a
solar collector.

On a global scale, wind energy is some of the
cheapest electricity on the planet. In Alaska, there
are abundant wind resources available for energy
development. High costs associated with fossil
fuel-based generation and improvements in wind
power technology make this clean, renewable energy
resource attractive to many communities. The wind
map on these pages shows the estimated wind
resource across the state. The colors represent the
estimated Wind Power Class in each area, with Class
1 being the weakest and Class 7 the strongest. The
quality of a wind resource is key to determining the
feasibility of a project, but other important factors to
consider include the size of a community’s electrical
load, the price of displaced fuels, turbine foundation
costs, the length of transmission lines and other site-
specifi c variables.
Alaska’s best wind resources are largely located in the
western and coastal portions of the state. In parts of
Southwest Alaska, turbines may actually need to be
sited away from the strongest winds to avoid extreme
gusts and turbulence. While average wind speeds
tend to be much lower in the Interior, areas such as
Healy and Delta Junction have strong wind resources.
The quality of the wind resource is very site-specifi c,
so it is critical to measure the wind resource before
starting development. Site-specifi c wind resource
data has been collected from around the state and is
available on AEA’s website at akenergyauthority.org.
Wind power technologies that are used in Alaska
range from small systems at off-grid homes and
remote camps, to medium-sized, wind-diesel hybrid
power systems in isolated villages, to large, megawatt
scale turbines along the Railbelt and in communities
like Kodiak, Kotzebue, and Nome. On the Railbelt,
utilities and independent power producers have
installed three wind projects to diversify the region’s
energy mix and provide a hedge against rising fossil
fuel prices. Those projects are a 17.6-MW wind farm
near Anchorage on Fire Island, Golden Valley Electric
Association’s 24.6-MW Eva Creek wind farm near
Healy and a 1.9-MW wind farm near Delta Junction.
At the end of 2017, Alaska had a total installed wind
capacity of 67 MW.
Rural Alaska, which is largely powered by expensive
diesel fuel, has seen rapid development of
community-scale, wind-diesel systems in recent
years. In 2009, Kodiak Electric Association (KEA)
installed the state’s fi rst megawatt-scale turbines
and then doubled the size of its wind farm in 2012.
The project’s six 1.5 MW turbines now supply more
than 18 percent of the community’s electricity.
Combined with the Terror Lake hydroelectric
project, KEA can now shut off their diesel
generators almost all year. Alaska Village
Electric Cooperative has wind-diesel hybrid
systems installed in 12 of the 55 western and
interior villages it serves, and is developing
projects in at least fi ve other communities.
Unalakleet Valley Electric Cooperative added
a 600 kW wind farm in 2009. Kotzebue added
two 900 kW turbines in 2012, more than doubling
its wind capacity. Nome also installed two 900 kW
turbines in 2013.

Alaska’s Renewable Energy Fund (REF), administered
by the Alaska Energy Authority, was created by
the legislature in 2008 with the intent to lower
and stabilize the cost of energy in Alaska through
increased use of renewable energy. The program,
originally authorized for fi ve years, was extended to
2023 by the legislature in 2012.
Over the last decade, the Renewable Energy Fund,
through state investment of nearly $270 million, has
acted as a major catalyst for the renewable energy
market sector in Alaska. Benefi ts from renewable
energy projects that have been brought online
as a result of the fund are felt throughout Alaska;
from integrating wind into diesel systems in small,
western Alaska villages to investing in wind and
hydro generation to serve the Railbelt region which
stretches from Fairbanks to Seward and Homer.
Grants have been awarded for reconnaissance and
feasibility studies, as well as design and construction
projects covering a wide range of technologies and
geographic areas. State investment in all stages of
project development have supported local fi nancial
participation far exceeding total grant funded
amounts.
The program is helping communities stabilize energy
prices by reducing their dependence on diesel fuel
for power generation and space heating.
In 2017, 79 projects displaced roughly 30 million
diesel-equivalent gallons of fuel worth more than $74
million. These numbers will continue to grow as more
projects that have received state support come into
operation. As of June 2019 there are more than ten
projects to be constructed through the program.
The estimated present value of the benefi ts of
currently operational REF projects is nearly $1.5
billion, with $583 million in capital costs including
$171 million of REF investment. If, overall, projects
operate as expected, the benefi t-cost ratio is 2.53;
this means for every dollar invested (by the State,
community, or other project contributors), the
community should see a benefi t of $2.53.
The program is a competitive application process,
administered by AEA and guided by the Renewable
Energy Fund Advisory Committee (REFAC), which
is comprised of nine members, fi ve of whom are
appointed by the governor, two by the speaker of
the house and two by the senate president.
To qualify for funding, project developers must
submit applications to AEA during an open
solicitation. AEA then ranks the proposed
projects based on economic and technical
feasibility, local support, matching funding
and the community’s cost of energy.
These rankings are vetted by the REFAC
and then submitted to the legislature,
which approves the projects and
appropriates funding.

State and federal policies that encourage renewable energy
projects play a crucial role in their development.
For the last quarter century, the federal Production Tax Credit
(PTC) has been the primary incentive tool for renewable
electricity in the United States. Congress passed the PTC in
1992 to even the playing field between the renewable energy
industry and the fossil fuel and nuclear industries. The subsidy
provides a credit for each kilowatt-hour (kWh) a project produces
over the first 10 years of its operation, incentivizing efficient
operations and maintenance. In late 2015, Congress introduced
a five-year extension of the PTC that included a gradual phasing
down of the 2.4 cent/kWh credit for wind energy, beginning in
2017. Projects that start construction in 2019, the final year of the
credit, will receive just 40 percent of the 2.4 cents/kWh credit for
10 years. The PTC for geothermal, closed-loop biomass and solar
energy all ended at the beginning of 2018. The bipartisan deal
also called for an extension and phasing out of the other major
federal incentive for wind developers, the Investment Tax Credit
(ITC). The ITC is a separate incentive that has allowed project
developers to elect to take a one-time tax credit of 30 percent
of the total cost of the project’s construction, instead of the PTC.
Wind projects that begin construction in 2019 will receive a 12
percent tax credit, before the ITC goes away completely. The
30 percent ITC for solar was extended through 2019, when it
begins to ratchet down. After 2023, the residential credit will
drop to zero while the commercial and utility credit will drop to a
permanent 10 percent.
Because of the uncertainty surrounding federal policy, individual
state policies have historically been the primary drivers of
renewable energy development in the United States. The three
primary policies used across the country have been net metering,
renewable portfolio standards and various forms of innovative
public financing. As the threat of climate change intensifies, an
increasing number of jurisdictions are also considering pricing
carbon emissions to encourage renewable energy development,
both directly and indirectly.
Net Metering
State net metering rules provide an incentive for individuals and
businesses to invest in their own small renewable energy systems
by allowing them to sell excess power that they produce back
into the grid. More than 40 states, including Alaska, offer some
form of net metering. Different rules in each state determine the
maximum amount of power individual producers can sell back to
the utility, the price at which the utility must purchase the power
and the length of time an individual producer can “bank” the
power they produce before a “net” bill must be calculated.
Alaska’s net metering regulations, promulgated in 2010, apply
to renewable energy systems of 25 kW or less and require large
utilities to purchase up to 1.5 percent of the utility’s average
load from customers who install projects. Customers receive
an amount equal to what the utility is able to avoid spending
on fuel and operations to generate the electricity. The number
of customer-built projects, particularly solar photovoltaic, is
beginning to grow rapidly and at least one utility is projected to
reach the 1.5 percent cap set by the Regulatory Commission of
Alaska (RCA) sometime around 2022.
Renewable Portfolio Standards
A Renewable Portfolio Standard (RPS) is a state law requiring
utility companies to generate a specified percentage of their
electricity from renewable resources by a certain date. RPS
requirements in the US vary widely on a number of factors,
including the percentage and end-date. In 2015, Hawaii became
the first state to require 100 percent of its electricity to be
generated by renewables (by 2045). California, the fifth largest
economy in the world, now has an RPS that requires 100 percent
of all of that state’s electricity to be produced by renewables by
2030. Utilities are typically given interim milestones and must
pay a fine if they do not reach those milestones. Most states
allow utilities to purchase Renewable Energy Credits (REC’s)
to meet these standards and avoid paying fines. Each REC
represents the production of one megawatt-hour of renewable
energy and the displacement of approximately 1,400 pounds of
CO2 emissions. Buyers of REC’s include utilities trying to meet
state RPS requirements and a growing number of corporations,
agencies and municipalities committed to supporting increased
renewable energy production. The RPS approach forces different
entities and renewable energy resources to compete to meet the
standard.
Twenty-nine states, Washington, DC and three U.S. territories
currently have RPS’s. An additional eight states and one territory
have renewable portfolio goals. In 2010, Alaska set a non-
binding goal to generate 50 percent of the state’s electricity
from renewable sources by 2025. Bills have been proposed in
Congress to create a mandatory national Renewable Electricity
Renewable Energy Policies Standard (RES) but so far all have failed to pass both the House
and Senate.
Clean Energy Funds
Clean energy funds support the development of renewable
energy and energy efficiency by helping remove market barriers
and educating the public. State clean energy funds are supported
through small, mill-rated utility surcharges called system benefit
charges. Programs that are supported through these funds
support research and development, provide low-income energy
assistance and develop infrastructure and clean energy financing
mechanisms. For example, system benefit charges in Oregon are
deposited into the independent Energy Trust of Oregon to fund
eligible efficiency, wind, solar electric, biomass, small-scale hydro,
tidal, geothermal and fuel cell projects through grants, loans,
rebates, equity investments and other financing mechanisms.
Today several states, nations and even one county are forming
“green banks” that specifically finance energy efficiency and
renewable energy projects. These entities pioneer programs
that reduce project risk and induce the private banking sector to
partner on investments. The Connecticut Green Bank receives
a significant portion of its annual working capital from a system
benefit charge of $0.001/kWh of electricity sold in the state
each year. The bank now leverages eight private sector banking
dollars for every $1 the state loans for clean energy development
through the Green Bank.
Alaska’s Renewable Energy Fund (REF) was established in 2008 to
support renewable energy development and is funded through
annual legislative appropriations. So far, the Alaska legislature has
appropriated $270 million to the REF, attracting additional private
and federal dollars to fund many reconnaissance and feasibility
studies as well as the construction of over 80 projects, mostly in
rural Alaska.
Property Assessed Clean Energy (PACE) programs allow local
tax assessment districts to loan money to property taxpayers
for energy efficiency and renewable energy development.
The municipality or tax assessment district is then repaid by a
special voluntary tax assessment on the property. In this way,
the loan goes with the building, not the individual who initiated
the transaction. In 2017, the Alaska legislature passed a bill
to authorize PACE loans to be made to commercial building
owners. Three large boroughs and municipalities in the state
are working together with other stakeholders to develop local
Commercial PACE (C-PACE) programs and a single statewide
program administrator. In states like Connecticut, the Green
Bank provides the dollars that municipalities use for PACE loans.
These municipalities pay the Green Bank back as the special tax
assessments on the improved properties are collected. A similar
set-up could work in Alaska as well.
Carbon Pricing
Carbon pricing schemes generally fall into two categories: cap
and trade systems and carbon taxes. Revenue-positive pricing
schemes accrue new revenue for the state, province or nation
which can be reinvested in renewable energy development or
other programs or funds. Several state legislatures in the US are
now considering carbon pricing systems, while other states are
considering setting up study commissions to better understand
the potential economic and policy impacts of carbon pricing.
Carbon trading systems set a cap on the allowable Greenhouse
Gas (GHG) emissions in a jurisdiction and then distribute permits
that can be purchased and traded among emitters. Cap and
trade systems use market forces to determine the price of the
GHG emissions. Nine states in the Northeastern US are part of
the Regional Greenhouse Gas Initiative (RGGI) which was put
in place in 2009. California established its own cap and trade
system in 2006 that also allows emitters subject to the system to
comply by supporting carbon mitigation projects in other states.
In 2018, Sealaska Corporation was issued 11 million carbon credit
offsets by the California Air Resources Board to set aside 165,000
forested acres for use as a carbon bank for 100 years. Other
Alaska Native Corporations are working on similar mitigation
projects as well. In 2008, British Columbia established a revenue-
neutral carbon tax that is rebated back to the citizens of the
province through income and business tax cuts and a low-income
tax credit.
Recent Alaska clean energy policy
In 2008, the Cold Climate Housing Research Center published
the first of two reports outlining recommended state programs,
initiatives, and goals to reduce end-use energy demand and
keep hundreds of millions of dollars in the state’s economy each
year. The state legislature appropriated the first $360 million of
an eventual $600 million for home weatherization and rebate
programs that year. Since then, over 45,000 Alaskan homes have
been weatherized, with an average energy bill savings of 30
percent.
In 2010, the Alaska State Legislature passed two other important
bills – SB 220 and HB 306. House Bill 306 established non-
binding goals to produce 50 percent of the state’s electricity from
renewable resources by 2025 and reduce energy use 15 percent
per capita by 2020. Among other provisions, SB 220 mandated
that 25 percent of the state’s public facilities over 10,000 square
feet be energy retrofitted by 2020, a goal met by 2015. Efficiency
improvements to state facilities since 2010 are now achieving a
cumulative annual cost avoidance of approximately $3.4 million.
As market demand and scientific innovation continues to
drive down the price of technologies like wind and solar,
governments are increasingly considering a wide range of
policies to encourage renewable energy and energy efficiency
and reduce greenhouse gases emissions. In Alaska, the
Regulatory Commission of Alaska (RCA) and the legislature are
both considering grid reform measures in the Railbelt such as
mandating a regional approach to reliability, interconnection,
protocols, economic dispatch and region-wide generation and
transmission planning that would lead to greater renewable
energy investment.

Energy effi ciency fi rst! Energy effi ciency is a common-
sense fi rst step in realizing renewable energy targets.
It’s also a critical component of an effective climate
change adaptation and mitigation strategy. Energy
effi cient buildings, lighting, heating systems and
appliances provide the same level of service as less
effi cient ones, but use less energy. Energy effi ciency
is typically the least expensive, most cost-effective
and quickest energy improvement that can be
made, and it should be the very fi rst thing done
when looking at cost-savings opportunities within
a community energy system. Effi ciency translates
to saved energy and money, and it creates a strong
foundation for renewable energy. For these reasons,
the Alaska Energy Effi ciency Partnership, a working
group of over 50 organizational members from the
public, private and non-profi t sectors, is guided by
a vision that Alaska can be the most energy effi cient
state in the nation.
Each year, Alaska’s residential and commercial
sectors use an estimated 118 trillion BTUs of energy
for power and space heat. Of this, approximately
45 percent is used in residential buildings and 55
percent is used in public and private commercial
buildings/facilities. Reducing building energy use
by 15 percent would save nearly 18 trillion BTUs
annually. At $2 per gallon for diesel fuel, a 15-percent
energy effi ciency improvement in residential,
commercial and public buildings could save $260
million each year.
Alaska has had great success with energy effi ciency
programs over the last decade. In the residential
sector, Alaska Housing Finance Corporation (AHFC)
has led the way with Low Income Weatherization
as well as the now dormant Home Energy Rebate
Program. Between 2008 and 2018, these two
programs provided effi ciency improvements to more
than 50,000 households across Alaska, resulting
in an average energy savings of 30 percent,
the creation of more than 4,000 jobs, and an
estimated $56 million in energy savings to
Alaska households per year.
AEA administered two programs for the non-
residential building sector. Between 2006 and 2016,
AEA’s Village Energy Effi ciency Program (VEEP)
implemented effi ciency measures in public buildings
and facilities in nearly 150 communities throughout
rural Alaska. Since 2011, AEA’s Commercial Building
Energy Audit (CBEA) program has provided rebates
for more than 230 privately owned, non-residential
buildings in both urban and rural communities
throughout the state.
Finally, the Alaska Department of Transportation
and Public Facilities works to improve the
effi ciency of State of Alaska buildings and facilities
through its Energy Program offi ce. Between 2010
and 2019, DOT&PF’s Energy Program facilitated
effi ciency improvements to over 25
percent of state-owned facilities,
achieving a cumulative annual cost
avoidance of more than $3.4 million.
The most important path forward for energy
effi ciency efforts in Alaska is working with
homeowners, business owners, facility managers,
regional organizations, lending institutions,
policymakers and others to develop appropriate
policies and effective, accessible tools to fi nance
building effi ciency projects. With the right policies
and tools in place, effi ciency projects can be cash
fl ow positive from day one, allowing for the payment
of project costs simply through the savings generated
each month. Commercial Property-Assessed Clean
Energy (C-PACE), utility on-bill fi nancing and the
establishment of a green bank are policy and tools
under development and/or consideration that if
utilized, could put Alaska on the path to being one of
the most energy effi cient states in the nation.

Energy efficiency improvements help individuals, businesses
and governments use less energy, save money and strengthen
local economies. Efficiency measures also help achieve the
state’s energy efficiency and renewable energy goals. While the
availability of natural resources used to generate electricity and
heat varies by location, energy efficiency is available in every
corner of the state.
Residential Energy Efficiency Case Study
Alaska Housing Finance Corporation (AHFC) administers the
Weatherization at No-Cost program with the goal of assisting
homeowners as well as renters in achieving energy efficiency
at no cost to qualified applicants. In 2018, the program helped
a customer in Quinhagak realize a 70 percent reduction in air
leakage. After an initial audit revealed numerous gaps in the
sheeting and several missing sheets of plywood, AHFC added
two-inch extruded styrene and covered it with plywood, reducing
exterior heat loss. By using spray foam on the seams and edges,
the floor was effectively sealed, increasing the R-value of the
home. Exterior walls, windows and door seams were caulked,
and a fresh coat of paint was applied to seal the walls from
the outside. Since many of the windows were either broken or
inoperable, new windows were installed, dramatically reducing air
leakage. Overall, the home retrofit resulted in a reduced airflow
of an impressive 70 percent, improving efficiency, comfort and
safety for the occupants, while also reducing heating costs.
Commercial Energy Efficiency Case Study
The Department of Transportation and Public Facilities (DOT&PF)
continues its mission of energy efficiency upgrades to state
public facilities and infrastructure. In 2018, the Department
implemented an energy efficiency project at the Anton Anderson
Memorial (Whittier) Tunnel using an Energy Savings Performance
Contract (ESPC) with an Energy Services Company (ESCO). The
project is expected to save over $150,000 annually. This type of
energy efficiency project improves existing infrastructure, reduces
costs of operations and creates quality jobs for Alaskans.
DOT&PF’s energy program works with other State of Alaska
departments and agencies to facilitate energy efficiency
improvements in public facilities. Projects have been completed
throughout Alaska with cumulative annual energy savings of over
$3.4M. DOT&PF administers an ongoing ESPC Term Agreement
to implement these energy efficiency projects.
Whole Community Case Study
In 2008, AEA and several project partners undertook an
intensive energy efficiency improvement effort in the small, rural
community of Nightmute. An extension of the Village Energy
Efficiency Program (VEEP), the “Whole Village Retrofit” (WVR)
included energy efficient lighting and weatherization upgrades
in 13 community buildings and four teacher-housing units.
The effort was intended to maximize possible energy savings
and mitigate the effects of rising heating oil prices. With state
and federal funding complemented by significant local cash
and in-kind matching, the project reduced electricity use by
an estimated 59 percent and displaced nearly 5,000 gallons of
heating oil in the weatherized buildings.
Across the state, energy efficiency consistently rises to the top of
local and regional energy project priority lists. The 2017 Alaska
Affordable Energy Strategy (AkAES), a comprehensive research,
analysis and recommendations initiative looking at ways to make
energy more affordable in all but Railbelt Alaska, identified
energy efficiency as the single most cost-effective resource for
addressing the high cost of energy throughout the state. One of
the studies done for the AkAES was an analysis of how Alaska’s
portfolio of energy efficiency delivery programs and financing
tools can be improved, including the WVR model. The study
Energy Efficiency Program Highlights
found that although direct state funding is still needed to capture
the opportunity in rural Alaska, a suite of policies--including
building codes, minimum product standards and promoting
regional solutions--could help to further capture the energy
efficiency opportunities in communities.
Outreach and Education
The Alaska Energy Efficiency Partnership began in 2010 with the
explicit purpose of working collaboratively to improve public
awareness about the abundant savings opportunities through
efficiency and conservation, and to help move the needle toward
adoption of technology and behavior to save energy and money
through energy efficiency and conservation. This ad hoc working
group includes participants from public, private and nonprofit
sector organizations that continue to meet quarterly to discuss
collaborative opportunities in program development, project
implementation and coordinated outreach. One example of the
latter is the annual Power Pledge Challenge.
In 2018, Alaska Electric Light and Power (AEL&P), Alaska Energy
Authority (AEA), Alaska Housing Finance Corporation (AHFC),
Alaska Village Electric Cooperative (AVEC), City of Seward,
Chugach Electric Association (CEA), Homer Electric Association
(HEA), Matanuska Electric Association (MEA), Municipal Light
and Power (ML&P) and Renewable Energy Alaska Project (REAP)
teamed up to put on the fifth annual Power Pledge Challenge
(PPC). The PPC educates middle school students across the
state about energy efficiency and conservation. Through a
presentation and hands-on activities, students learn about
calculating electricity use and ways to reduce personal energy
consumption. The students then go online and pledge to do
three things to reduce their energy use to enter to win a regional
prize for their class. If more than 75 percent of a class completes
the online pledge, then their class is entered to win the state
prize. In 2018 over 3,000 students from grades six through eight
participated in the PPC.
Financing
Energy efficiency is an investment opportunity. It’s more than
swapping out lightbulbs and adding insulation – it creates
economic opportunity while improving comfort all without
compromising convenience. Using electricity and heat is an
unavoidable reality in our state, where the associated costs for
these critical services are double or triple the cost outside Alaska.
And, despite relatively short-lived trends to the contrary, energy
prices generally only go up over time. The longer a person or
community waits to take action, the longer energy and money
is wasted unnecessarily. Energy efficiency investment grows
incrementally, generating savings that can be continuously
reinvested in homes, businesses and communities. An investment
in energy efficiency is an investment in the future.
Like any good investment, investing in efficiency requires a
financial commitment. The savings opportunity, however, can
be significant enough that it’s worth taking a loan to make this
commitment. The cost of repaying that loan is often smaller than
the savings generated by the efficiency improvements the loan
affords. We’re talking about energy efficiency financing, and it’s
the way of the future.
To finance an efficiency investment, start with information. First,
have the building or facility audited to see what kind of savings
are possible. Then, have the project cost and savings estimates
verified to develop a scope of work. To complete the project,
consider working with a project developer. Make sure to initiate
negotiations with a lender, public or private. Make sure you get
the savings that were promised. And then reap the rewards of the
hard work with lower energy bills, a healthier indoor air quality
and more money to spend on other, more important things.
