    1. 1. USVI Energy RoadmapAdam Warren, PhD (NREL)<br />Credit: Don Buchanan, VI Energy Office <br />Credit: Warren Gretz, NREL <br />Credit: Don Buchanan, VI Energy Office <br />EDIN-USVI Energy Workshop<br />April 7-8, 2011<br />Univ. of the Virgin Islands, St. Thomas<br />
    2. 2. 4/6/11<br />1<br />Our motivation<br />Electricity Cost = Fixed Cost (Poles, Wires, Equipment) + LEAC<br />
    3. 3. 4/6/11<br />2<br />Our motivation<br />EIA: annual average price of low sulfur crude oil real 2009 dollars per barrel<br />Factors not considered:<br />
    4. 4. What is EDIN?<br />EDIN is an international partnership between USA, New Zealand, and Iceland started in 2008.<br />Why Islands? <br /><ul><li>Islands are often highly dependent on fossil fuelsfor electricity and transportation and often have very high retail electricity rates
    5. 5. Islands often have abundant renewable resourcesand small populations, so are ideal places to showcase the future of high renewable energy penetration.</li></li></ul><li>EDIN-USVI Background<br />
    6. 6. 5<br />Feb 2010 – Declaration of our mission<br />At the MOU signing ceremony with DOE and DOI, Gov. deJongh, Jr. announced his goal to reduce USVI’s dependence of fossil fuel by60% by 2025.<br />“There is no reason why the Virgin Islands cannot be the leaders in clean energy deployment in the Caribbean,” deJongh said. <br />
    7. 7. 6<br />June 2010 – Formation of Working Groups<br />
    8. 8. November 2010 –“How do we get to 60x25?”<br />
    9. 9. Diverse set of stakeholders working together to ask the right questions and find the answers<br />VIEO & WAPA<br />Working Groups<br />
    10. 10. April 2011 Workshop<br />Critique draft Energy Roadmap<br />What can be done? What can’t?<br />What have we missed?<br /> Identify and eliminate Barriers.<br />Working Groups<br />Mission<br />Values<br />Goal<br />
    11. 11. Agenda<br />Discussions, not presentations.<br />
    12. 12. EDIN-USVI Background<br />Organize<br />Plan<br />Assess<br />Implement<br />
    13. 13. 12<br />EDIN-USVI Process<br />“60x25”<br />
    14. 14. 13<br />USVI Energy Roadmap<br />
    15. 15. Methodology: Relate everything to barrels of oil<br />Waste heat<br />Electricity<br />= LEAC<br />Water<br />Electricity Cost = Fixed Cost (Poles, Wires, Equipment) + LEAC<br />
    16. 16. Determine Business as Usual (BAU)<br />- What will happen if we don’t do anything<br />
    17. 17. Determine Business as Usual (BAU)<br />- Mix of EE & RE to achieve 60% by 2025<br />60% by 2025<br />
    18. 18. Analyze roadmaps to 60% by 2025<br />A different view<br />60% by 2025<br />
    19. 19. Multiple paths are possible<br />Emphasize energy efficiency    Emphasize renewable energy<br />
    20. 20. 4/6/11<br />19<br />Key Findings<br /><ul><li>It can be done, but only with all stakeholders pulling together, in the same direction.
    21. 21. The kitchen sink – it’s going to take everything to get to 60% by 2025.
    22. 22. WAPA must lead. All scenarios include waste-to-energy and increased generation/water efficiency.</li></li></ul><li>4/6/11<br />20<br />A few details<br />RE / Fossil Fuel <br />Mix<br />60 x 2025<br />
