of 400MW. Average availability over the last 3 years is at 96.57%.
Palmiet Pumped Storage
Scheme is part of a water transfer scheme. For generating purposes, water is
released from the upper Rockview Dam to the two reversible pump turbines located 60 metres
below ground level. The units can also be used to pump additional water from the
Palmiet River via the Rockview Dam to the Steenbras Dam to supplement the Cape Town
water supply. The station can be operated by remote control from Eskom’s National
Control Centre at Simmerpan. Palmiet is located in an ecologically sensitive area, home to
species of fynbos found nowhere else in the world except the south-western Cape.
The whole Palmiet site is
a conservation area and in December 1998 the area was declared a Biosphere
Reserve by UNESCO – the first in South Africa. In March 2001, Palmiet was awarded NOSCAR
status by the National Occupational Safety Association (NOSA) for the first time.
