Cape Town opens bidding for battery energy storage facility

Cape Town building battery storage to beat price hikes

The City of Cape Town has announced that it has opened bidding to potential tenderers to construct a battery energy storage facility.

The facility will be constructed at the City's Atlantis Solar PV plant, targeting a minimum rated power output of 5MW and a useable energy storage capacity of 8MW.

Don't understand this, how is having battery storage facility going to help with price hikes if you still need Eskom to change the batteries? Unless it's going to be a solar farm with a battery storage capacity.

Just skimmed through the article but did not see any mention of solar panels.

The facility will be constructed at the City’s Atlantis Solar PV plant, targeting a minimum rated power output of 5MW and a useable energy storage capacity of 8MW.

This will be able to power 300 homes with an average consumption of 25kWh per day.

Energy storage is measured in J or Wh
Energy consumption is measured in W.

A "day" is not an SI unit. It could be 12h or 24h.

Why can't you guys get this right? Did the editor not have physical science in school?

COCT should stop f__king about and just install one of these on one of the mountains:


Can generate 450 MW of power when needed, and can store the equivilant of 3600 MWh.




That polygon has the same area as the aforementioned dam. And then just use sea water as the water source. (You don't have to build it right on top of woodhead if that is needed).

Because Table mountain is about 5 times higher than the aforementioned dam, you could roughly hold 5 times as much energy for the same size reservoir due to the height difference.

So make it big enough to power the city for a couple of days, and COCT could likely be energy independent just with solar.

Do consider the City of Cape Town only supplies about 40% of the Cape Town population with electricity. The rest is Eskom direct.

Did you see the recent Practical Engineering video on that dam? The sensor that monitored the water level malfunctioned and the pump kept pumping water till the damn overflowed and broke (because it didn't have a spillway.)..

Imagine you flood Gardens...
