Wind Energy and Barbados
Onshore utility scale
Past experience
• One 200kW wind turbine
• Installed in parish of St Lucy
• Concrete tower
• Stainless steel blades
• Operated from 1984 - 1988
• Many reliability problems
• Eventually abandoned due to
safety concerns

Wind Energy and Barbados
Onshore utility scale
• 10MW wind farm planned in St Lucy parish (expected 2014)
• 30% capacity factor is estimated (comparable with good wind farms)
• Onshore, utility scale wind is limited by available locations
• Only 3-4 potential sites available in Barbados
• Planning is currently a big issue for wind farm installation
• Would meet ~3% of Barbados’s energy needs

Offshore
20m depth contour
The pro’s of offshore
•Better wind regimes offshore
•Less disturbance for a space limited island
•Easier to install larger turbines
However, technical challenges are large
•~50% more expensive to install offshore
•O&M costs are higher
•Currently limited to 20m water depth
Proposed 10MW
wind farm site

Small scale
3kW Kestrel e400 residential installation
Small Wind is starting to appear (<10kW)
Cost of electricity ~33 US¢/kWh
BL&P Renewable Energy Pilot project
- 200 installations or 1.6MW of grid-connect
- Net metering at ~20 US¢/kWh
