I wait impatiently for Durban / eThekwini to announce the same, or similar

Is this the minucipalities showing their "power" vs. Eskom (government)?

FYI.

The 180 MW Steenbras Power Station, located 50 km from Cape Town near Gordon’s Bay in the Western Cape, was the first hydroelectric pumped-storage scheme in Africa when it was built more than 30 years ago. It was primarily intended to generate during peak loads and is used as the regulating station on the City of Cape Town’s electricity distribution network.

Each of the station’s four 45 000 kW generator units acts as a pump-motor in one mode and a turbine-generator in the other. Surplus national generating capacity is employed to utilise relatively low cost off-peak electricity available at night to pump water from a lower to an upper storage reservoir. During periods of peak demand in the day the water is released back to the lower reservoir, thereby generating electricity as in a conventional hydroelectric power station.

Simple and effective.

This sucks! I live in Gotdon's bay and we fall under Eskom, not City of Cape Town. I am less than 2 km from the Steenbras Power Station, and yet, we were load shed on Saterday! Bastards!

This is what they do when they "save" electricity. They pump the water uphill.
Always wondered how electricity was "saved"

Indeed. There are two or three dams doing the same somewhere in the Drakensberg and if I'm not mistaken they are building more int KZN somewhere (water shortage and all...)

Here you go: https://en.wikipedia.org/wiki/Drakensberg_Pumped_Storage_Scheme
Four dams are involved in the scheme; the Driekloof Dam (joined to the Sterkfontein Dam), the Kilburn Dam, the Woodstock Dam and the Driel Barrage. Electricity generation equipment is located between Driekloof Dam and Kilburn Dam.[3] Since the Driekloof Dam/Sterkfontein Dam also forms part of the Tugela-Vaal Water Project some of the water pumped to Driekloof Dam might end up flowing to the Vaal Dam and not be available for return to the Kilburn Dam. The Woodstock Dam and Driel Barrage are used to supply this additional water to Kilburn Dam when required.

The scheme provides for up to 27.6 gigawatt-hours (99 TJ) of electricity storage in the form of 27,000,000 cubic metres (950,000,000 cu ft) of water. The water is pumped to Driekloof during times of low national power consumption (generally over weekends) and released back into Kilburn through four 250 megawatts (340,000 hp) turbine generators in times of high electricity demand.

https://en.wikipedia.org/wiki/Ingula_Pumped_Storage_Scheme

The Ingula Pumped Storage Scheme (previously named Braamhoek) is currently being constructed by an Eskom and CMC Impregilo Mavundla Joint Venture in the escarpment of the Little Drakensberg range straddling the border of the KwaZulu-Natal and Free State provinces, South Africa. It is about 22 km (14 mi) southwest of Van Reenen. The pumped-storage hydroelectric scheme consists of an upper and a lower dam 4.6 kilometres (2.9 mi) apart and connected to a power station by tunnels.[2] The scheme is being built at a cost of US$3.5 billion (R25 billion).[3] Construction began in 2005 and the power station scheduled to begin operations in late 2015

And scheduled to experience technical faults that impact its capacity in January, February, March, April, May, June, July, August, September, October, November and December 2016.
