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
Outline • What is happening • What is necessary to get started • Issues and priorities
Playa Kanoa Annual production: about 45 GWh
Tera Kora The process for the repowering of this wind farm has begun in 2007
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

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
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
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
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
Issues and priorities • Resource assessment • Land availability and ownership • Grid connection issues • Power purchase contract and financeability • Policy issues and legal support • Environmental impacts
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
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.
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
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
Why resource assessment is so important • An example of an energy yield calculation • Total annual yield 3476688 kWh
Why resource assessment is so important, cont’d • An example of an energy yield calculation • Total annual yield 3920617 kWh
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
