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. The project will produce 90% of all Gustavus
electric requirements. This Hydroelectric output is
based on hydrologic analysis of the stream and
projected electric usage.
Unit depends on project type (e.g. windspeed, hydropower output, biomasss fuel)
