    EDIN-USVI Energy Workshop
    April 7-8, 2011
    Univ. of the Virgin Islands, St. Thomas

    1
    Our motivation
    Electricity Cost = Fixed Cost (Poles, Wires, Equipment) + LEAC
  • 3. 4/6/11
    2
    Our motivation
    EIA: annual average price of low sulfur crude oil real 2009 dollars per barrel
    Factors not considered:
  • 4. What is EDIN?
    EDIN is an international partnership between USA, New Zealand, and Iceland started in 2008.
    Why Islands?
    • Islands are often highly dependent on fossil fuelsfor electricity and transportation and often have very high retail electricity rates
    • 5. Islands often have abundant renewable resourcesand small populations, so are ideal places to showcase the future of high renewable energy penetration.
  • EDIN-USVI Background
  • 6. 5
    Feb 2010 – Declaration of our mission
    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.
    “There is no reason why the Virgin Islands cannot be the leaders in clean energy deployment in the Caribbean,” deJongh said.
  • 7. 6
    June 2010 – Formation of Working Groups
  • 8. November 2010 –“How do we get to 60x25?”
  • 9. Diverse set of stakeholders working together to ask the right questions and find the answers
    VIEO & WAPA
    Working Groups
  • 10. April 2011 Workshop
    Critique draft Energy Roadmap
    What can be done? What can’t?
    What have we missed?
    Identify and eliminate Barriers.

    USVI Energy Roadmap
  • 15. Methodology: Relate everything to barrels of oil
    Waste heat
    Electricity
    = LEAC
    Water
    Electricity Cost = Fixed Cost (Poles, Wires, Equipment) + LEAC
  • 16. Determine Business as Usual (BAU)
    - What will happen if we don’t do anything
  • 17. Determine Business as Usual (BAU)
    - Mix of EE & RE to achieve 60% by 2025
    60% by 2025
  • 18. Analyze roadmaps to 60% by 2025
    A different view
    60% by 2025
  • 19. Multiple paths are possible
    Emphasize energy efficiency    Emphasize renewable energy

    Key Findings
    • It can be done, but only with all stakeholders pulling together, in the same direction.
    • 21. The kitchen sink – it’s going to take everything to get to 60% by 2025.
    • 22. WAPA must lead. All scenarios include waste-to-energy and increased generation/water efficiency.
