CoCT can draw 180MW from it's Steenbras pumped storage scheme as well as it's two gas turbine plants in Roggebaai (42 MW) and Athlone (36 MW) for a total of 258MW.
If it wasn't for the red tape surounding use of IPPs, Cape Town wouldn't have load shedding at all.
Nope those two gas turbine plants are owned and operated by the CoCT.
And yeah, the pumped storage was built not to curb loadshedding but to deliver power during peak demand periods when Eskom charges the city more for electricity.
As long as there is no overnight loadshedding it should continue to do it's thing. It basically needs to be "charged" (water pumped back up) every night and if there is load shedding 24/7 then it is not economically feasable nor energy efficient to do so.
Yeah it wasn't broken, just undergoing scheduled maintenance over the summer. CoCT is also supplemenring power generation with gas turbines.
Problem is if Eskom starts with their overnight loadshedding BS again, Steenbras isn't going to be worth a damn. (no pun intended)
