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. 9,900,000,000 BTU max. output for GSHP well field
Unit depends on project type (e.g. windspeed, hydropower output, biomasss fuel)
2. Existing Energy Generation – Traditional oil and electric heat system shown for comparison
a) Basic configuration (if system is part of the railbelt grid, leave this section blank)
i. Number of generators/boilers/other 3 boilers oil heat : 2 boilers electric heat
ii. Rated capacity of generators/boilers/other (1) @ 478 MBH, (2) @ 765 MBH : (2) @ 1300 MBH
iii. Generator/boilers/other type 3 boilers oil heat : 2 boilers electric heat
iv. Age of generators/boilers/other New
v. Efficiency of generators/boilers/other 77% oil : 95% electric
b) Annual O&M cost
i. Annual O&M cost for labor $4200 oil heat : $1000 electric heat : $1720 GSHP
ii. Annual O&M cost for non-labor $1200 oil heat : $500 electric heat : $1500 GSHP
c) Annual electricity production and fuel usage – this project will not produce electricity
