RFA AEA10-015 Application Cost Worksheet Page 1 10-7-09
Please note that some fields might not be applicable for all technologies or all project phases. The
level of information detail varies according to phase requirements.
1. Renewable Energy Source
The Applicant should demonstrate that the renewable energ y resource is available on a sustainable
basis.
Annual average resource availability. Solar thermal storage – used in combination as a hybrid
heat pump and solar collection system – is conceptually
designed to work year round
Unit depends on project type (e.g. windspeed, hydropower output, biomasss fuel)
