1 Robust High Penetration Micro Grid Solution A Presentation for the PPDIUC

2 Solar Diesel Hybrid System Using renewable sources reduces expensive diesel fuel consumption reducing the cost of power generation in remote locations Reduced emissions from diesel power generation Significant renewable penetration without compromising reliability

3 A project for the DA NAXDA WX First Nation Only accessible by water Harbledown Island is an island in the Central Coast region of British Columbia Approximately 30 residents 60 kw, 60 kw and 95kw diesel generators Until April 2017 diesel power generation only Among the more than 170 First Nation diesel powered communities in Canada Harbledown Island

4 Motor Generator Extremely robust construction ideal for harsh environment 150% step load within operating parameter specifications, no tripping Powered by battery Simple to operate and maintain commercially available technology

5 Energy storage system Nissan LEAF Lithium Ion (one of the most commercially available mass produced batteries on the planet) Size 4cm thick, 31cm long, 25cm wide 96 = 22 kwh x 10 packs = 220 kwh in series creating 390vdc The battery is much more robust if it is not fully discharged Our battery management control system will allow optimum use of the battery to stay within specification for 25 years Temperature controlled environment for batteries very important 15c for optimal battery life.

6 Controls Proven ComAp control systems in place in 10s of thousands of remote locations Automated control of diesel / battery power management ComAp touch screen monitors / scada / plc controls built into SIMMAX control system Superior control of diesel / hybrid parameters compared to any other system

7 Project Costs for Remote Locations 90 kw Solar / 220kwh storage / 215 kw diesel (95kw + 60kw + 60kw) Solar - $6.50 per watt installed Batteries and MG sets - $1.45 per watt hour installed Diesel - $1.35 per watt installed

8 Robustness and Reliability Output is Motor Generator set bomb proof True AC power output Minimal power electronics so more reliable Simpler to work on, less qualified techs required Incomparably robust Easily synchronized Supports diesel off mode

9 Scalability Currently working in communities from 100kw up to the 4000kw in size Easily integrated into existing systems Expandable as the community grows

10 Efficiency The US Government National Renewable Energy Laboratory states that the typical solar system losses are 14% Vs Harbledown at 12%

11 Diesel Fuel Mitigation 52,000 liters per year on an average 50kw of load Approximately $2 per liter depending on delivery costs $104, savings Does not include approximately $80, maintenance (oil, filters, belts, etc.) cost savings as the diesels will not be running most of the time

12 Noise diesel generators will run less than 50% of the time on an annual basis Less potential diesel fuel contamination because there will be less transportation, less spillage, less diesel fuel storage required CO2 mitigation 52, kgs per liter = 139 tons of CO2 mitigated annually Lower carbon footprint, less maintenance less consumables oil etc. Environmental

13 Demonstration Site The T Sou-Ke first nation demonstration site has been up and running since Harbledown commissioning is complete and the hybrid facility is ready for visitors this coming summer

14 We believe there will be many options for remote power generation in the future. The Global Micro Grid Solar Diesel Hybrid Solution is a glimpse at the future now The Future

15 Conclusion The Solar Diesel Hybrid solution can now provide cost effective reliable environmentally friendly critical power for remote locations Reliable because you still have diesel generators as a backbone for the system Maximum reduction of diesel fuel for least amount of money Environmentally beneficial solution without giving up reliability and robustness The hybrid is the portal to high penetration renewables in remote communities
