Installed capacity is growing apace…

  • Fastest growing markets: Europe, North America, Asia

  • Turbines cannot be built fast enough

  • Why is the Caribbean falling behind?

Modern caribbean experiences with wind energy
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
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
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
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
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
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
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 d1
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
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 d1
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
