  1. Wind Energy in the Caribbean the time is NOW! Presented by Margo Guda Fundashon Antiyano Pa Energia Curaçao, Netherlands Antilles At the Wind Energy Workshop Presented by the V.I. Energy Office St Thomas, USVI January 31, 2008

  2. Outline • What is happening • What is necessary to get started • Issues and priorities

  3. Playa Kanoa Annual production: about 45 GWh

  4. Tera Kora The process for the repowering of this wind farm has begun in 2007

  5. Wigton wind farm

  6. French Caribbean projects Grand Maison Wind farm 9 machines, 2.4 MW. VERGNET La Mahaudière Wind farm 11 machines, 3 MW. VERGNET Morne Carrière Wind farm 4 machines, 1.1 MW. VERGNET Union Electrica / VERGNET Isla de la Juventud, Cuba. 6 machines, 1.7 MW

  8. NREL wind map

  9. Winds in the Caribbean on a random day

  10. Global installed capacity

  11. Installed capacity is growing apace… • Fastest growing markets: Europe, North America, Asia • Turbines cannot be built fast enough • Why is the Caribbean falling behind? Source: GWEC, Brussels 2006

  12. Wind: installed capacity in the Caribbean region

  13. Wind energy installed in the Caribbean region

  14. Modern Caribbean experiences with wind energy • Curaçao – since 1984 • Bonaire – since 1984 • Barbados – since 1984 • Guadeloupe and Martinique – since 1993 • Jamaica – since 2004 • Cuba – since 2007

  15. Caribbean wind energy projects and plans • Aruba – plans, no machines yet • Barbados – plans, no machines yet • Bonaire – project nearing construction phase • Curaçao – two wind farms, work on extension ongoing • Guyana – negotiations ongoing • Jamaica – wind farm, talk of extension • Panama – plans, no machines yet

  16. Caribbean wind energy projects and plans, cont’d • Cuba – wind farm, construction for more seems to be ongoing • Dominican Republic - plans, some machines in storage but nothing operating as yet • St Vincent – plans; project ongoing • St Lucia – plans; project ongoing • St Eustatius – plans; project ongoing • Colombian Guajira – resource assessment in progress for wind farm site; ongoing

  17. Issues and priorities • Resource assessment • Land availability and ownership • Grid connection issues • Power purchase contract and financeability • Policy issues and legal support • Environmental impacts

  18. What is necessary to get started • Resource assessment: • Identify promising locations • Assure access • Land availability and ownership: • Identify owners of promising locations • Address access issues • Identify environmental issues • Grid connection: • Distance to grid • Grid capability • Policy issues and legal support: • IPP status • Grid access • other

  19. Resource assessment • Identify promising regions, based on • Local informants • Biological and other indicators • General topography • Other modeled information, if available • Collect and analyze existing data, both long-time (reference) and shorter period data, if available • Perform correlation analysis on data sets in the same wind regime • Collect period data for locations of interest • Use correlation with long-term data set to estimate long-term characteristics, including wind energy density.

  20. Resource assessment, cont’d • Data to collect for promising sites: • Average hourly wind speed • Wind direction, hourly average • Turbulence intensity • Shear coefficient from ground level to at least hub height • Recommended measurement period one year • Unless there is very good correlation with a nearby reference site

  21. Resource assessment, cont’d • Characteristics of interest: • Diurnal variation of hourly wind speed • Diurnal variation of wind direction • Diurnal variation of turbulence • Diurnal variation of shear coefficient or vertical profile of the wind speed • Seasonal variations of these variables • Annual distribution of hourly wind speeds • Analysis of extreme wind speeds’ occurrence and risk analysis

  22. Why resource assessment is so important • An example of an energy yield calculation • Total annual yield 3476688 kWh

  23. Why resource assessment is so important, cont’d • An example of an energy yield calculation • Total annual yield 3920617 kWh

  24. Why resource assessment is so important, cont’d • Resource assessment allows for matching wind regime and turbine • Matching regime and wind turbine allows for maximizing output • Optimal machine sizing determines the best energy cost • Therefore resource assessment is crucial to the success of a project
