Phase One:

A resource assessment of the wave power potential was completed in the year 2002. The results showed that SA has an average annual wave power density of 17kW/m of wave-length and an average winter wave power density of about 30kW/m. This results allowed Eskom to make the decision to continue its research in the wave power field. 

Phase 2: 

This phase of the study involves a techno-economic and technology selection study. This study aims to identify all the developments regarding wave power conversion technologies world wide and to suggest a technology that can be used in SA. This study ended in December 2004. At this stage no technology both locally and internationally was commercially available for possible implementation in SA.  Eskom then decided to continue monitoring these technologies until such a time a technology proved to be technically sound and economically feasible to be added to Eskom's generation mix.

Phase 3

The next phase of the study will be to conduct a SEA. This will be done on the open tender process and the study should be completed by end of 2007. Along with this study, Eskom will continue to monitor international activities. The current step is to perform a site selection study based on certain screening criteria. This study will be completed by end of September 2007.
