Could the sudden breakdowns from last week have caused them to build in more margin between demand and available power?

Buffer is already big enough to account for that, its nearly 10% of available generation lol
 
Near Matjiesfontein, apparently:

Renewable Energy Project Development | About Oya | Renewable Energy

Oya Energy Hybrid Facility is the first and largest renewable energy project of its kind: A hybrid dispatchable facility consisting of solar, wind and storage,
oya.energy
Oya Energy (Pty) Ltd will own and operate the 128 MW plant near the town of Matjiesfontein, straddling the Western and Northern Cape Provinces. The Oya Energy Hybrid Facility falls within the Komsberg Renewable Energy Development Zone (REDZ), as Gazetted on 16 February 2018 (GN 114)
The 128MW Oya Energy Hybrid Facility will offer dispatchable renewable energy for the RMIPPPP programme. The Project will utilise co-located wind turbines, solar PV arrays, Lithium-Ion batteries and a hybrid controller that orchestrates all three technologies to provide dispatchable power to the grid as and when needed.

  • The Hybrid Project has a total contracted dispatchable capacity of 128MW.
    • Wind: 86.4MW
    • Solar PV:155MWp bi-facial solar PV modules
    • Battery: 94MW / 242MWh
  • Construction of the Oya Energy Hybrid Facility should start end of 2023 with a fast-tracked completion date of no longer than 18 months thereafter to help ease South Africa’s power crisis.

A disappointing amount of power...at max output, only 1/10th of a stage of LS. :cautious:

True. I do think these newer projects which include storage are big step up on those earlier solar-only ones though. I think Eskom now only wants to sign PPAs for projects which can consistently supply from 5am to 9pm which makes sense.

Welcome to renewables... Massive amounts of land and resources to get barely an OCGT worth of power.
What we need to do is build CCGTs, use natural gas. As you can run CCGTs all the time, you just ramp up or down, in fact they are the base of the English power grid

Don’t we need natural gas first?

Hook it up to parliament, sure there is enough there :-P
Plus we are the 30th largest producer of gas in the world

South Africa natural gas production

South Africa is the world’s 30th largest producer of natural gas and the country's output decreased by 2% in 2023, over 2022.

I thought the fields are depleted, that’s why petrosa closed down.

Petrosa exists today for those hairdresser diesel contracts to eskom.

Before my dad retired, he used to work for one of SA's petroleum companies and he told me a story that Petro SA once expressed interest in purchasing them but early on, Petro SA realised they didn't even have the cash available so the deal was quickly called off. Basically it was a waste of everybody's time.
