Developer Astrum Energy said initial tests had showed the area, near Empangeni, had sufficient wind to make a project viable.
Astrum also said it had a preliminary agreement in place with state utility Eskom.
There is only one other major project under development in South Africa at the moment - Eskom’s 100MW demonstration development outside Cape Town.
The country only has 10MW turning to date.
South Africa had been hailed as a likely location for the next global wind rush, with large industry players investing 4-5 million rand ($592,000-740,000) ahead of the commencement of the country's Renewable Energy Feed-In Tariff (REFIT).
But the mood of optimism has now changed to frustration as REFIT has been delayed while government departments argue amongst themselves behind closed doors.
