South African energy trader Etana Energy has reported that it will purchase all of the renewable electricity generated by two new wind farms being built by global renewables group Acciona Energía for the first 20 years of operation. The Zen (100 MW) and Bergrivier (94 MW) windfarms, with a combined export capacity of 190 MW, are located between Gouda and Saron in the Western Cape and are expected to produce about 580 GWh/y of renewable electricity.
