Application Cost Worksheet
Please note that some fields might not be applicable for all technologies or all project
phases. Level of information detail varies according to phase requirements.
1. Renewable Energy Source
The Applicant should demonstrate that the renewable energy resource is available on a
sustainable basis.
Annual average resource availability. Wood chip biomass fuel 2000 to 3000 tons/year
available by barge from Craig and/or Prince of
Wales Island and eventually from local thinning.
Unit depends on project type (e.g. windspeed, hydropower output, biomasss fuel)
