2 Presentation Agenda Interesting rooftop applications and the impact solar penetration can have University of Queensland QUT KJM Woolworths Solar penetration Impact on retail power pricing and the network performance Factors to consider when considering non FiT based economics and projects Peak demand charges Reliability of network connection Costs of network, regulatory and local government can impact returns Positive and negative examples in a non FiT environment

3 Snapshot: About Ingenero Power company specialising in Solar Electricity Generation Utility Scale, Commercial and Industrial Rooftop & Residential Developed considerable expertise in the Hybrid Grid market Experienced in both Electricity Sales (PPA s) and turnkey projects Technically strong Across technologies Around broader systems aspects of monitoring, electrical engineering and network connectivity Solar design Financial engineering Project management Strong & experienced management team Utility experience in power, data and telecommunications The leading Solar EPC company in Australia due to breadth of installations and technology Commenced operations in Thailand January 2014

4 Commercial Rooftops Ingenero A brand you can trust Government & Utilities Construction Retail Airports Education Kingscote Airport

5 Hybrid Energy Systems Tonga Hybrid Grid Project 500kW of solar PV 100kW of battery storage Ground mounted Fully integrated with existing diesel power station 70% of noon time load of the entire grid is serviced by the PV Rio Tinto Hybrid Grid Project Largest mining and solar off-grid project in the world ~7MW of solar with high penetration Very harsh environment High winds Dirty /dusty Very remote

6 University of Queensland Lessons Develop a good public (web) interface to show off your system and its capabilities; Spend a little bit of money on simple things like a viewing platform; Spend time analyzing what your optimal (minimal) cleaning regime is to save operational costs; Have a robust and rigorous panel inspection regime in place. It is nice to see German quality engineering and construction in Australia WIRSOL AG ** Top 50 university, QS World Rankings 2011 One of the best examples of quality installation I have seen world wide. Power-One

7 Queensland University of Technology Challenges Working at heights Working as part of a larger project Working with a large construction company Design and protection close to humans Lessons Regulatory requirements drives unexpected costs into the project Large company interfaces can be time consuming and expensive Project management critical

8 KJM 500kW Self Consumption Application Challenges Working within the allowable network grid voltage Network settings around Rate of Change of Frequency Protection (ROCOF) Lessons Must be able to engage with the networks on their terms

9 Small Commercial Installations..Solar and gasoline can mix Challenges One of the first gas station/solar installations in the world Heavily regulated environment Lessons First always takes longer Regulatory interface critical Project Management

12 Is Solar PV Cost Competitive The price of Solar PV has fallen dramatically in the last 5 years For many businesses and building owners, solar PV can provide a cost effective means of lowering their energy bills and locking in savings for the long term The feasibility of PV is highly dependent on the tariff structure It is also highly dependant upon network stability and the details around network connectivity Cost competitiveness can also be impacted by network, safety and local government regulations Whilst PV lowers a business AVERAGE peak demand, it may not consistently reduce it s MAXIMUM peak demand
