 RFA AEA11-005 Application Cost Worksheet Page 1 7-21-10 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 energy resource is available on a sustainable basis. Annual average resource availability. 7.78 m/s average wind speed AEA Unit depends on project type (e.g. windspeed, hydropower output, biomasss fuel) 2. Existing Energy Generation and Usage a) Basic configuration (if system is part of the Railbelt1 grid, leave this section blank) i. Number of generators/boilers/other 4 gensets, I flywheel, 5 turbines, 3 primary boilers ii. Rated capacity of generators/boilers/other Diesel 2@ 260kW 1@230kW, 1@122kW, f475kW wind, 600 thermal kW iii. Generator/boilers/other type iv. Age of generators/boilers/other Recent, 2005 – two gensets 2009 v. Efficiency of generators/boilers/other 13.0 kWhr/gal est b) Annual O&M cost (if system is part of the Railbelt grid, leave this section blank) i. Annual O&M cost for labor ii. Annual O&M cost for non-labor c) Annual electricity production and fuel usage (fill in as applicable) (if system is part of the Railbelt grid, leave this section blank) i. Electricity [kWh] 1,019,419 ii. Fuel usage Diesel [gal] 81,658 gallons Other iii. Peak Load 280 kW iv. Average Load 190 kW v. Minimum Load 120 kW est vi. Efficiency vii. Future trends 1. Typical
overall
usage
of
electricity
has
a
growth
rate
of
2%
per
year.
 






2.



More
importantly,
peak
and
average
loads
are
increasing
in
large
 steps
with
the
addition
of
new
facilities.

A
new
school
will
open
in
Kong
this
 winter.


The
school
will
have
an
average
operating
power
requirement
of
 65
kW.

New
airport
buildings
and
runway
lighting
will
be
added
next
spring.

 A
new
clinic,
new
housing
units
as
well
as
water
and
sewer
improvements
 are
planned
before
2015.
Each
of
these
Infrastructure
improvements
will
 result
in
increases
in
both
peak
and
average
electrical
loads. d) Annual heating fuel usage (fill in as applicable)
