Prince of Wales residents were invited to attend an Air Source Heat Pump Expo on this spring at the Craig High School. The Expo featured guest speaker Dana Fischer from Efficiency Maine, and included mechanical contractors, financial institutions, and experts statewide through a webinar.
The event was organized because the micro-grid that supplies POW residents with electricity will soon have more hydro power electricity on-line, than the island currently demands. Today most of POW residents use diesel oil to heat buildings; the new hydro plant may provide a unique opportunity for residents to convert to a more efficient and sustainable heating option.
What are Air Source Heat Pumps? Air source heat pumps (ASHP) use electricity to circulate air through a heat pump, this is the same technology used in your refrigerator, but in reverse. The heat pump extracts heat from the air outside and transfers it into the building. Even in cold climates, outdoor air contains heat. The efficiency of a heat pump will change with the temperature outside. High performance ASHP models have been shown to perform at, and below, 00F.
In southeast Alaska’s mild climate, heat pumps can have a coefficient of efficiency (COE) that surpasses other heating technologies. For example, a COE of 2 means that for every one unit of energy which goes into the heat pump system, two units of energy are produced. It is typical for a heat pump unit to deliver four units of heat for every unit of electricity at 50°F, but only deliver two units of heat for every unit of electricity at a temperature of zero. However, a COE of two is still much better than the COE for heating fuel (COE of 0.85), or electric space heaters (COE of 1), neither of which change depending on temperature.
Electric Rates and Conversion to an ASHP: Hiilangaay Hydropower is expected to come online in 2018. The 5-megawatt hydropower project near Hydaburg will eliminate the need for diesel powered electric generation (except during times of maintenance), and result in a surplus of clean energy available for future growth on the island. Growth in electric demand will actually result in utility fixed costs being spread over a larger sales base, resulting in downward pressure on rates.
Prince of Wales residential customers currently pay $0.25 per kWh, $0.23 per kWh with Power Cost Equalization (PCE). Heat pump use and the related cost will vary by household circumstances. AP&T strongly encourages customers to do their own research and analysis based on the cost of heating fuel, electricity, heating habits, and the age/ efficiency of the old heating system.
It can be challenging for consumers to predict the cost comparison over time, because today’s fuel and electric prices are unlikely to be the same as tomorrows. One advantage offered by ASHPs on Prince of Wales Island is that they provide more stable, predictable pricing due to the fact that they use locally available hydropower. The price of hydropower is relatively flat, and is not susceptible to global events which impact the supply and price of oil.
Homeowners are encouraged to maintain a back up heat system for very cold temperatures. This allows consumers to use fuel if diesel prices temporarily fall, allowing residents to take advantage of temporary price swings. Some consumers also choose to keep wood stoves or propane heaters as supplemental heat sources.
The Cold Climate Housing Research Center has done a lot of research on the effectiveness of ASHP’s in Alaska, and specifically in SE Alaska.

Written by Sienna Reid for Capital City Weekly
As a lifelong Sitkan I have grown close to our coastal rainforest. As I head off to my first year of college this fall, I know I will miss this place. However, I can’t help but wonder — how much will it change?
Having just graduated from Mt. Edgecumbe High School, a boarding school that serves students across Alaska, I have heard many stories of successful hunts and summers spent at fish camp, but I also hear stories of quickly changing ecosystems. Every community in Southeast Alaska depends on natural resources in some way. Whether it’s harvesting wild foods or building homes out of local wood, our people depend on the land. In order to maintain our unique way of life, it is important that rural Alaskans have opportunities to pursue meaningful careers that promote sustainable living and wise management of these resources.
Today, many Southeast Alaskan communities are home to a variety of youth workforce development programs. These programs help prepare the next generation of Alaska’s scientists, field crews, and resource managers with the experiences, drive, and skills to pursue careers in their backyards, whether on the water or in the woods. This summer I visited three of these programs — in Sitka, Klawock, and Kake — to get an inside perspective on the impact they are having on our region.
Ocean Acidification Mentorship
On a drizzly Sunday morning I hopped in the car with three girls and a tote full of water sampling equipment. We made our way from the Sitka Sound Science Center to the sampling site, walked down a slippery dock, and got to work.
The team used a niskin bottle to collect water samples at five feet, both from the surface and at the ocean floor since acidity can vary throughout different depths. After transferring the water into a tinted bottle to lessen light exposure, the water temperature was recorded and mercury was added to poison the sample. Mercury kills all of the living organisms in the water to preserve the exact conditions at the time of collection; for example, it would stop processes like photosynthesis which could potentially alter the results of the test.
Through this mentorship program with the Sitka Sound Science Center, Lily Hood, Muriel Reid, Gabrielle Barber and I had been testing Sitka’s waters to get baseline information on the acidity of our ocean. High acidity poses a threat to the marine food chain, putting our fisheries at risk. Later this fall, the team will process their samples, interview local fishermen, and present their findings at the Alaska Marine Science Symposium.
Muriel Reid, 16, appreciated the chance to learn through fieldwork this summer.
“In classrooms…whenever you’re confused the teacher is right there to help you, and so it’s a good thing for a learning environment, but it’s not necessarily good for jobs — learning how to be good in a job,” Reid said.
She said her favorite day was learning about calcium carbonate chemistry with mentors Lauren Bell and Esther Kennedy.
“That really shined (a) light on a lot of things that people don’t touch on in regular schools,” she said. “It’s definitely important to have connections to scientists in your area so that you can learn more easily, and not just be confused by a bunch of numbers on a page.”
By speaking with the participants, it was made clear that programs that get kids out of the classroom and into the field make the lessons learned in school more tangible. When science is applied, carbon chemistry is no longer a question on a test, it is a challenge that may affect the fisheries that feed our families. The opportunities this mentorship provides make science more relevant to the next generation of homegrown Alaska scientists.
Training Rural Alaskan Youth Leaders & Students
South of Sitka by 134 miles, I had the privilege of meeting a team of seven young Alaskans who were spending their summer in Klawock learning to work outdoors in the challenging conditions of the temperate rainforest. These hardworking teens and young adults were part of the Training Rural Alaskan Youth Leaders & Students (TRAYLS) program.
Founded to help youth learn workforce skills, many partners were involved in making TRAYLS a success. Bob Girt, environmental compliance and liaison specialist with Sealaska Timber Company, as well as one of the founders of TRAYLS, considers partners as those who donated resources, offered access to land for work, or in some way “provided major thrust for the program.”
Those partners include native organizations such as the Bureau of Indian affairs, Native American Fish & Wildlife Society, Organized Village of Kasaan, Sealaska Corporation, Sealaska Timber Company, LLC, Klawock Cooperative Association, Organized Village of Kake, and Kake Tribal Corporation; as well as other groups such as the Sustainable Southeast Partnership, The Nature Conservancy, USFS Ranger Districts Petersburg & Prince of Wales Is., State of Alaska – Division of Economic Development, City of Thorne Bay, and the City of Hydaburg.
This year marked the launch of the pilot program, one that partners and participants hope will continue for years into the future. The five crew members, aged 16-22, and their two crew leaders whisked me up a mountain to show off their hard work on the newly revitalized One Duke Trail. They pointed out the work they had done along the way.
“We want it to be friendly to everyone that wants to go on the trail,” explained crew leader, Talia Davis, 19, from Kake.
Although they were proud of the work they had done, Davis admitted that the labor was difficult in the beginning.
“You’re working in the mud in Southeast weather and you’re just questioning it all. But you know, if you make it through the first couple weeks it’s really rewarding… I’ve definitely decided that I want to work outdoors after this summer.”
The entire crew agreed that working outdoors was important to them. Crew member Yahaaira Ponce, 17, from Klawock, commented that TRAYLS had changed the way she saw her future.
“I wasn’t sure if I wanted, going into college, to study something to do (with) outdoors or not, because I was kind of in-between. But after this, I think I’m definitely looking to a career outdoors.”
This was exactly what Girt hoped the students would gain from the experience. Getting the young participants involved and excited about the work can have long lasting benefits for the towns they live in, explained Girt.
“I think it’s important that communities stay resilient, and the way they stay resilient, one of the ways is, they keep talented people that have some passion and ambition, and those people don’t go away and live in some other state or some other country,” Girt said. “They might go away for a while to get their training and get their skills, but they eventually will come back and…help their communities.”
Resilient communities need sustainable resources and a local workforce to manage those resources. But pursuing a career outdoors in Southeast Alaska can be daunting and folks are often unsure whether they would actually enjoy being out in the elements all day. As Girt and the students explained to me throughout the visit, programs like TRAYLS provide students a unique opportunity to try out these professions, all while gaining experience and valuable life skills that will benefit them no matter what career path they go down.
Sea Otter Research
Sonia Ibarra is a Ph.D. student originally from California, but has been living in Alaska for the past five years. Through the University of Alaska Fairbanks, she has been working in the rural villages of Southeast to study the effects of sea otter predation on shellfish. I visited Kake on a low-tide week so I could follow Ibarra and her three field assistants, who were recruited from rural Southeast villages, through the data collection process.
At 4:30 a.m. the first morning, we headed to the harbor with buckets and yawns. From the boat we scouted out a good sample location. Moving quickly down the zero tideline, quadrats were laid out, holes were dug, and clams were sifted into buckets. When we returned to Ibarra’s house it was time to sort and measure the clams and shells. It took a lot of work, but it also made great field experience.
Sarah Peele, 19, from Hydaburg, said the chance to get real-world research experience got her interested in this job.
“Working with Sonia, she’s showing me how to pair traditional knowledge with science,” she said.
I noticed the emphasis put on this idea while I was in Kake. In the living room of Ibarra’s house, where the floor was covered with medicinal plants laid out to dry, Ibarra explained how she had been criticized on her work; people had told her that speaking with locals wasn’t ‘real science.’ However, not only has she been gathering different perspectives, she has been backing them up with data collection.
“A lot of research in rural communities, and specifically native communities, you have a researcher come in, get their data, and leave,” Ibarra said. “And to me it’s very disrespectful to live life that way, or to do research that way.….I do research together with people in the community.”
By hiring these students from rural Southeast, she is keeping the work local and inspiring them as well. Shawaan Jackson-Gamble, 19 from Kake, has been working with Ibarra for the past three years.
“I wasn’t really looking for a biology job,” he said, “but it opened my eyes a little more, and by my next year working with her it’s what I wanted to do.”
With his family roots in Kake and growing up with a traditional lifestyle, he hopes to return to Southeast after college to work for his tribe with a focus on subsistence. Programs like Ibarra’s are encouraging local students like Jackson-Gamble to see how science can be a tool in answering questions that are important to their culture, families, and communities.
After a summer spent traveling around Southeast Alaska, I was reminded of how fortunate we are to live surrounded by natural resources. I also discovered the significance of this human resource; young, eager learners who are preparing themselves to take on the challenges of managing these lands and waters. These programs require time, money, and the dedication of everyone involved. However, the opinions of the young participants indicates the work is well worth the effort. Youth workforce development programs like the ones I visited this year are more than just a summer job. They are an investment for the future of Southeast Alaska.

On a warm, bluebird day in April, Southeast Island School District and the Sustainable Southeast Partnership led a 25 person tour to Coffman Cove, Thorne Bay and Kasaan on Prince of Wales Island to see their biomass and greenhouse projects in person. Tour participants from Hoonah, Kake, Hydaburg, Klawock, Petersburg, Tenakee Springs, Ontario and the Yukon each had in hand a Biomass Heated Greenhouse Handbook. This comprehensive handbook outlines how to turn these inspiring greenhouses from dream to reality. It was unveiled a day prior at the Alaska Wood Energy Conference in Ketchikan and is a free resource available to schools and anybody who is interested in building a Biomass Heated Greenhouse locally. The USDA Forest Service and the Alaska Energy Authority commissioned the Handbook, in part to share successes and lessons learned from the Southeast Island School District and help streamline the process for future projects. Nobody wants to re-invent the wheel, and handbooks like these provide the tools so that interested local leaders don’t need to!
“We teach retention, other schools teach compliance” –Colter Barnes
Back on the tour on Prince of Wales Island, five to seven year old students confidently walked out to the chicken coop to do their morning chores – collecting and counting eggs, feeding chickens and ducks, refilling water. Two high schooler’s run outside to the biomass boiler shed to stoke the fire between classes. A middle school class weighs goldfish, calculates the amount of fish food to feed them (3% of their mass), and tests the water levels in the aquaponic greenhouse.
Of the 500 plus schools in Alaska, four on Prince of Wales Island are now displacing heating fuel and imported foods with local woody biomass and greenhouses. According to Principal Colter Barnes, the $200 earned from delivering a cord of wood can make a big difference for families in these high cost communities, and produces about the same amount of heat as $500 worth of diesel fuel. Students fund sports travel and even requested more duties stoking the boiler and hauling and cutting wood a couple of weeks ago to save up for prom.
These greenhouses are truly inspiring. They are creating jobs and economic development, generating clean, affordable, local energy, teaching nutrition and culinary arts, applied learning, and community engagement. This is a story of building healthy, culturally vibrant communities and a more resilient region and the newly published handbook will help take this fantastic island-wide project to the next level.
Reflections from Ian Johnson, Community Catalyst in Hoonah
The community of Hoonah is currently working to determine if a district biomass heat-loop and biomass-linked greenhouse are right for our community. We are hoping to save energy and cultivate more local produce here in rural Alaska.
Lucky for Hoonah, schools on Prince of Wales Island are already pioneering biomass-heated greenhouses. The Sustainable Southeast Partnership is great because it helps connect ideas and successes from one community, and share them with change-makers across our region. The Biomass Greenhouse Tour arranged by Shaina Kilcoyne and Lia Heifetz of the Sustainable Southeast Partnership, brought 5 community members from Hoonah and 21 other participants from Alaska and Canada to Prince of Wales to examine their biomass linked greenhouses. The experience was powerful.
We started in Coffman Cove with the gardeners of the future – the kindergarten class is tasked with feeding the chickens each morning and collecting eggs. It was delightful, heart-warming, and inspiring to see their bond with the chickens and the enjoyment of their work. From there we learned from the high schoolers and Principal, Colter Barnes how the local biomass sourcing provides money to the local economy ($175/ cord) while warming the greenhouse at a cost savings compared to diesel – a $175 cord of wood is equivalent to about $500 in diesel.
We then moved to the large greenhouse in Coffman cove and were given a tour by the middle-schoolers who run it’s aquaponics operation and harvesting. The excitement was truly electric as it became evident that the Coffman Cove model creates student involvement, provides to the local economy during the lean winter months, generates food security, and provides money to the school through produce sales. These were just SOME of the benefits of their incredible operation. We continued our learning by visiting the greenhouses at Thorne Bay and Kasaan to learn about how we can scale our greenhouses and about slightly different boiler systems. Ending the day at the the Whale House in Kasaan was just icing on the cake!
I can’t thank enough Shaina and Lia for putting together this incredible event. I know it will cause quite a stir in Hoonah and we begin to look at our greenhouse options here.
Are you a business or commercial building owner interested in saving money on your heating and electric bills? An energy audit will show you how energy is used in your facility and will recommend ways to reduce your use and save money.
Southeast Conference, Renewable Energy Alaska Project (REAP) and the Sustainable Southeast Partnership (SSP) are offering 75% off commercial building audits through the U.S. Department of Agriculture’s Rural Development program. There are limited seats left, so don’t miss this opportunity to sign up.
Last year, businesses and public facilities in Hoonah, Haines and Prince of Wales Island participated, receiving 29 Level I energy audits and 5 Level II audits. The 34 audited buildings totaled over 230,000 ft2. In all, the recommended energy efficiency measures total $382,701. These lighting, heating, ventilation and other recommendations will yield an estimated annual savings of $173,782! This means that it will take only a little over two years for these savings to pay for themselves.
Join the movement to save money and save energy for Southeast Alaska! Interested Southeast businesses should contact Robert Venables (firstname.lastname@example.org) or Shaina Kilcoyne (email@example.com). Communities will need at least three businesses to get them on the Auditor’s schedule, so talk to your neighbors! With an audit, businesses will be eligible for USDA’s Rural Energy for America grant and loan Program for renewable energy and energy efficiency measures. Loan Guarantees are completed continuously throughout the year.
