WIND PROGRAMME

The Wind Programme intends to assess wind potential available around the country with the plan for a long-term monitoring for promising sites.  The programme involves undertaking three spot-checks at different times in a year to determine the feasibility of a particular site.  Once proven feasible, a wind monitoring station is set up to record wind data for 24 to 36 months.

This year, an important aspect that the Department wishes to embark on is to ascertain the data that has been used in the construction of the Wind Map for Viti Levu/Vanua Levu and Ovalau.   With the enormous resources needed for the exercise, the first stage of the project would specifically be for Viti Levu.  This would involve desk studies on prime sites available in Viti Levu and once ascertained, wind monitoring stations will be installed at these sites.  With wind, the monitoring period is expected to be around 24 – 36 months depending on the consistency and availability of data.  With the conclusion of this assessment work, we do hope that we will be able to ascertain the good potential wind regimes in Fiji.

In view of the above, the following is a list of requirements that would ensure the feasibility of a particular site.

Requirements: fig3

The site surveyed should:

  • Have a good wind regime
  • Be located at a high elevation
  • Not to obscured by tress or any other objects that may disrupt the flow of the wind at the site


Current Wind Monitoring Stations

The Department currently has wind monitoring stations installed in the following sites:

  • Dakuilomaloma Village, Vanuabalavu, Lau
  • Nabouwalu Government Station, Bua


These two stations are currently not working and works are underway for the repairs of the stations.  Furthermore, the Department plans to install more wind monitoring stations before the end of the year.

With respect to the above, the following table shows a list of wind monitoring stations that have been installed by the Department over the years.

For wind monitoring assessments, loss of data is something to be expected.  Not all sites will have all data present.  This above table shows a number of sites which have had data missing for some periods during monitoring.  The Department during its assessments and monitoring hopes to improve this for new monitoring stations planned for installation.
