The Tanana Solar Therma-1-Public Facilities Spacing Heating Project seeks to demonstrate and
implement the market tTansfonnative benefits of combining biomass space heating technologies
currently bein-g installed. at Tanana's public facilities with solar thermal collectors. The
synergistic combination of these two technologies and shared thermal storage capacity will serve
to result in reduced imported petroleum consumption and also serve to optimize operation of the
biomass boilers currently being Is at Tanana.
Heat energy is, by far, the greatest financial burden facing Alaskans, and particularly those in
rural Alaska. It i-s also the most critical as heat during Alaska's extreme winters is a matter of
Sk
survival., Many rural communities in Alaska are moving in the direction of biomass as an

alternative to fuel oil for heat energy generation. Tanana has become a model 1*n Alaska for
demonstrating the effective use of renewable energy to reducing heat energy operational costs.
Tanana was one of the first villages in Alaska to incorporate the use of GARN biomass boilers
for offsetting the high expense of fuel oil for generating hot waterl'*n the community washeten*a,,
In 2011, as a part of a major biomass expansion project, systems are being installed in numerous
commercial and residential scale buildings.
Solar thermal is an excellent complement to the biomass boilers. During the winter months the
heat energy generated by the biomass boilers offsets a substantial amount of the fuel oil normally
required. The cordwood fael source also allows many of the operating costs t�Cii) remain in the
community since the supply of the cordwood and manpower required to feed and boilers is local.
During the summer the biomass boilers are a less desirable alternative. The focus and energies of
the community are diverted to essential traditional cultural activities. The, solar thermal, which is
a passive heat energy source that can operate largely unattended,, allows those activities to
continue uninterrupted. Thus it is an excellent companion to the bi c rnqv,.q antea„ oc „tr;t,,,tP

of the two heat energy sources Virtua
source.
ly eliminates the dependency on fuel oil as the heat energy
While used extensively throughout other parts of the U.S. and the world for years,, the use of
10
solar thermal technology as an alternative to fuel oil is relatively new. Equally new to Alaska is
the concept of solar thermal in conjunction with the biomass systems. The City believes that the
integration of solar thermal i*s essential to the continued development and expansion of the
biomass program in Alaska. The resulting combination system is more compatible with the life
stylesandcul al peoplei&nruralAlask reduces the ongoing operational
costs of the heat energy system,redureducessand the long term impact on the area biomass resource
due to the system operation.
For this project,ty the ofTanana has selected four buildings in Tanana that have biomass
systems — the wuo eria, the tribal complex, the teacher housing duplex, and a single residence
teacher housing unit. This mix represents a good cross section o oth commercially and
residentially onented systems. Due to the hizhly variable temperatures found in the biomass
systems, the City has selected indirect, glycol based evacuated tube collectors with variable
speed circulation pumps and supplemental heat storage tanks for the solar thermal systems. In
the washeteria, the integral storage of the GARN boilers will be utilized. In the other facilities
that are utilizing conobum gasification boilers with limited internal storage capacity,
supplemental storal e tanks will be installed in conjunction with the solar thermal.
2.6 PROJECT BENEFIT
Briefly discuss the financial and public benefits that will result from this project, (such as reduced fuel
costs, lower energy costs, etc.,)
Recent installations of high efficiency residential and public facility solar thermal collection
'I
systems in Alaska have demonstrated that significant solar thermal energy can be captured from
March through October and can provide si" fi cant quantities of heat to for domestic hot water
generation and also for supplement of space heating systems. The financial benefits relate to
displacement of usage of expensive petroleum -fired heating systems and can provide annual
operational savings to the Tanana heating systems) operators.

Key to combliaing high efficiency biomass heating systems with solar thermal collector systems
is that both share similar temperature operation ranges and as a result,, can also share common
thermal storage capacity which thereby lessen the upfront capital investment needed.

4.2.2 Existing Energy Resources Used
Briefly discuss your understanding of the existing energy resources. Include a brief discussion of
any impact the project may have on existing energy infrastructure and resources.
Tanana Village is located at the confluence of the Yukon and Tanana Rivers in Interior Alaska
with no road -connections to the rest of the State. Tanana represents a typical remote Alaskan
village attempting to make the transition to the modern world while maintaining its peoples'
unique relationship with the local geography and natural setting.. The economy is uniquely
Alaskan whereby the typical family maintains a mixed cash subsistence lifestyle an d where high
energy costs are threatening the very existence of Tanana and its people. This is because m1111113sillt
rural Alaskan households are spending up to 40 percent of their annual income (cash) an energy
this winter compared with 4 to 6 percent for the average urban household.
The City of Tanana (the City) has been actively seeking ways and funding to improve the
infrastructure, services and general living conditions in the community. This is being
accomplished through extensive community input. Tanana conducts an annual community
planning process which has prioritized a number o community development projects including
establishment of low-cost and environmentally sound energy efficiency and supply systems,.. This
DOE EECBG application seeks to carry -out a v1*11agemmwi e public facility energy efficiency
retrofit and bi'oa-mass (wood) space heating program in order to lessen cash leakage out of the
local economy and create long-term, renewable resources based employment. While significant
benefits will be immediately generated to the community of Tanana from this project, more
importantly, there is a regional Alaska benefit of this DOE EECBG project which is it will lead
the way for most of rural Alaska to replicate and as a result, produce a more sustainable rural
Alaskan economy and energy use system.
Tanana's delimina, as is the case for all of rural Alaska, is dependence on imported petroleum
heating oil for space heating of essential community facilities and infrastructure. This EECBG
project, will provide a market transformation example to the rest of rural Alaska by conducting
village-wide importation substitution of expensive, imported heati*n9iol by, first, increasing all of
do
Tanana's public facilities ermal/electrical consumption efficiency and, second, substituting oil-
fired space heating with three high efficiency io"mass (wood -fired) centralized heating plants
strategically located adjacent to clustered Tanana's public facilities.
