SETuP = Solar Energy Transformation Program 10 megawatts (MW) of solar power installed across 30
remote Indigenous NT communities over 3 years
Two main components:
• A medium penetration solar rollout:
– Reduce annual fuel use by 15% in over 30 communities
• Nauiyu (Daly River) high penetration solar site:
– 50% fuel savings
– Test integration of new technologies
– Enables diesel engines OFF

Financial model drives behaviours
High political interest in project viability
Focus on diesel prices & short-run inputs
Focus on how the loan payback works
NPV ‘doorstops’ – should certain communities be dropped?

Timetable drives behaviours
Aggressive timetable pressures learnings
but:
Focuses the mind
Aggressive timetable pressures land availability
but:
Alternative (‘fall-back’) communities are contentious

Technology drives behaviour
The 10 MW of SETuP is not insignificant in the NT
Interest & involvement
The $55m of SETuP is very significant in the NT
Great expectations
Diesel/gas generation - leave it to experts
PV? Everyone’s an expert!

ISSUES MANAGEMENT I
Balance: land availability with scheduled ARENA Milestones with climate (Wet)
Manage: Desire for large private pv penetration in SETuP communities
Massage: Solar-diesel hybrid won’t
negatively impact reliability
shorten diesel life
complicate day-to-day operation
drive up O&M
![Page 15: Graeme Marshall - NT Power & Water Corporation - Solar Transformation in the NT – Early lessons from SETuP](https://reader031.vdocuments.net/reader031/viewer/2022022203/5876e7011a28ab046d8b63df/html5/thumbnails/15.jpg)
ISSUES MANAGEMENT II
Keep the focus: on SETuP as a whole, try to avoid cherry-picking
Manage Expectations:
of communities for local employment (construction & longer-term)
of NT contractors & suppliers of big SETuP ‘paydays’
of parties that SETuP can be simultaneously a cash cow, a major employment generator and a technological showcase
of everyone that everything will work straight up

FINAL OBSERVATIONS
Hofstadter's Law: It always takes longer than you expect, even when you take into account Hofstadter's Law.
Less elegantly - Dates in a calendar are closer than they appear to be.
Data: Is not the plural of anecdote
