ROOM TO GROW

10. Potential for Wind Energy
Off Grid wind power has many limitations, and many
plusses...
Ireland is famous for wind coming off the North
Atlantic...
Clews Bay is a protected area of lesser islands, so
perfect...
Inishraher is a scaled project appropriate for phasing
in...
Wind is just one component for a complete off-grid
system...
A smart grid is sustainable, self-reliant, systems
oriented...

11. Wind + Turbine = Energy (maybe...)
Assess the power required
Size and spec the right turbine
Determine effective wind speed
Piece together system components
Budgeted cost analysis for Phase 1 wind
Triple bottom line assessment for Inishraher
Propose scope of development and project timing

14. Phase 1 Summary
Spreadsheet analysis for use of electrical requirements for 1 new
residential building and existing Farmhouse; 25 people full time
use
Best case scenario for Off-Grid Solar PV and Wind power
generation, backed up by propane generator
Wind generation is limited to 7kW by off-grid system and PV by
poor solar
Use of propane is already there to service heat, cooking and hot
water so backup by propane will be enhanced by extra wind
production
Cost analysis for the entire Phase 1 system comes in at
$152,000; that is almost $100,000 less than running a cable from
the mainland for $250,000, plus the ongoing cost of electric bill
and possible outages

15. Phase 2 Projection
The 2nd large residence and a smaller building will
add 25 more people, doubling the electrical need; a
repeat of the first system will be added after evaluating
and adjusting for productivity
Solar thermal hot water system using high efficiency
vacuum tube panels will be used to heat water and a
possible heating system
Propane use will come down by this, but a generator
will remain as permanent back-up system incase of
emergency or down-time.
