existing supply
• population = ~ 500,000
•electricity consumption = ~ 4 GWh pa
• average CO2 emissions from electricity
= ~ 8 tonnes per person per year
• ~ 95% electricity from outside the region
• 87% fossil fueled including CSG

renewables now
• ~ 70 MW or 4% PV
• (~ 72 MW or 16% sugar mill cogen)
• 11 MW hydro
• 1 MW wind

what’s working
•PV - 3 of top 10 postcodes in NSW
• Ballina pyrolysis plant
• TransGrid’s Stroud-Taree line stopped
• CSG stopped

what’s not
• 2 out of 3 sugar mill cogen plants notoperating
• Pelena Energy (micro hydro) closed down
• TransGrid still planning $250 millionBonshaw-Tenterfield-Lismore line

strengths + constraints
• high rainfall + humidity
• high population density + cost of land
• not suitable for large scale wind + solar
• no large tidal movements or wave energy
• no hot rocks
