Wrangell explores local biofuel production
March 7, 2012
By Charlotte Duren | KTSK Radio: Wrangell is taking a close look at its future energy needs. The Southeast Alaska Conservation Council (SEACC) held a meeting in Wrangell recently to discuss the issue and the role biofuels are playing in many Alaska communities. KSTK’s Charlotte Duren has more on some of the Southeast projects, as well as what some Wrangell residents are already doing.
As heating oil costs continue to rise, many Alaskans are looking for cheaper alternatives to meet their energy needs. One method is converting plants, paper, or wood waste into biomass to use as a renewable energy source.
“Probably about 5-years ago the fuel prices got extremely high for a period of time and I was burning about 12-hundred gallons of oil a year in my house and I knew I needed to do something different,” he says.
That’s Wrangell resident Carl Johnson. Johnson has been heating his two-story home with wood pellets for 5-years. He says it cut his heating costs dramatically.
“I went from about $4,500 a year in oil to about $1,200 in pellets. I spend about half in wood pellets than I would in oil,” he says.
He buys in bulk from a manufacturer in the Lower-48, as well as from a retailer in town. He says heating could cost even less if he could buy from a local manufacturer. At a recent meeting, SEACC Organizer Jeremy Maxand proposed just that.
“What we want to do is take a look at what the potential market penetration is for biofuels and look at the feasibility of building a manufacturing plant in Wrangell,” he says.
According to Southeast’s draft Integrated Resource Plan (IRP), a long-term generation and transmission study; there’s been a 50 percent increase in load on the hydropower system over the past 5-years. The IRP recommends the use of biofuels in homes and government buildings to help cut down on the load, as well as heating oil costs.
SEACC recently conducted a survey of residents in Wrangell and Petersburg to find out what types of energy people are using to heat their homes. It also asked whether people would be interested in using locally manufactured biofuel. Maxand, who is also Wrangell’s mayor, says 233 surveys were completed between the two communities.
“What we found in Wrangell and Petersburg, particularly in Wrangell is that 38% of respondents would be willing to purchase or use a locally manufactured product. And that is really important to know before you get too far down the road, to be able to know what the level of interest is,” he says.
Throughout Southeast Alaska, a number of successful biomass boiler projects have been developed. Sealaska Corporation’s Juneau headquarters has switched from oil to wood pellet heat. Craig and Thorne Bay heat school with waste-wood boilers.
Wrangell is considering manufacturing wood and paper briquettes that can be used in home wood stoves. Unlike pellet stoves, briquettes or “bio bricks” can be used just like regular firewood. Maxand says ultimately the conversion to biomass comes down to the needs of each individual community.
“We need to realize we are in a perfect storm right now between the Integrated Resource Plan, state funding, grant opportunities, small mills, municipal solid waste problem, you bring all these things together and you basically end up with an opportunity that can at least solve the heat side of the energy issue in Wrangell,” he says.
