REMOTE RENEWABLE ENERGY CONFERENCE
GRAEME MARSHALL
MELBOURNE ~ MARCH 2016
FOCUS
SETuP funding and construction models
Consequent behaviours
Land, procurement & contracts
Consequent behaviours
Expectations and reality

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?
SETuP rollout timing:
2015/16 2016/17 2017/18
4 sites
16+ sites
10 + sites
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!
LAND
Allowed ~ 3 hectares/MW + shading (trees) - ample
Average lease cost is $5500/ha/pa
On average, we produce 560wp/$ of annual lease cost
Lowest is 100wp/$
Highest is 2100wp/$
TECHNOLOGY
Inverters: SMA 25000 Tripower inverters
PV Controller: SMA Cluster Control
Panels: included Hanwha Q Cells, Canadian Solar, Jinko, Conergy and LG – 315 watt
Framing system: Clenergy Solar Terrace, Sigma XL, Conergy Linea
Prices per watt
Capital Cost Item Estimate Emerging Reality
Panel & inverters erected on frames
$3.10 $3.30
Balance of system $0.40 $0.45
Land costs $0.04 $0.037
Project management $0.50 $0.45
PvSyst power production
Section Latitude Average Mwhpa produced
1 MWp solar produces Mwhpa
1 (1.625 MWp) 25 - 22 South 3292.5 2026.1
2 (0.4 Mwp) 22 South 799.1 1997.6
3 (1.3 MWp) 12 South 2470.1 1900.0
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
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
