Tongatapu Wind Energy Feasibility Study, Tonga

Infratec was commissioned by the NZ Ministry of Foreign Affairs and Tonga Power to assess the feasibility of wind energy in Tongatapu. Infratec, in conjunction with Aurecon, visited Tonga in early 2014 to meet with key stakeholders and inspect proposed wind farm sites.

The first phase of the project, completed in May 2014, involved a review of wind data captured from two masts on the island, previous prefeasibility studies, assessing the two potential sites and developing a road map for a full feasibility study.

Phase two was completed in April 2015. This included assessing potential wind turbines for suitability, determining the preferred site for development, land owner negotiations, environmental impact assessments, geotechnical investigations, and producing final specifications and development costs for project funding applications.
