    Home Affairs has more downtime from network problems than load-shedding

    My favourite Home Affairs term for "the system is down" was heard in Paarl many years ago: "the online is offline."

    SA National Energy Development Institute's tips for building the best-value solar PV systems

    Since I'm currently so focussed on astronomy, I totally expected a working model of the Solar System after reading that title. My engineering background and many hours spent on PV did not even save me.

    Construction begins for Africa's first dedicated gigawatt battery storage plant in Cape Town

    Yep, and those containers are crammed with 14.3 kWh batteries (100+ per container!), which is why I contend that "battery" = 14.3 kWh in this case.

    Construction begins for Africa's first dedicated gigawatt battery storage plant in Cape Town

    I might also add that "gigawatt factory" is somewhat of an industry term, referring loosely to battery factories that produce more than 1 GWh per year. Musk probably started the inane naming 10 years ago with his "Gigafactory" concept. From there it morphed to "gigawatt factory". The definition...

    Construction begins for Africa's first dedicated gigawatt battery storage plant in Cape Town

    Indeed. I was trying to make sense of what "1 GWh / year" means as a unit of power. Maybe a better way of stating it is that it is the flow of electrons leaving the factory floor inside those batteries *if* they are full (and regardless of who filled them up). That's an interesting perspective...

    Construction begins for Africa's first dedicated gigawatt battery storage plant in Cape Town

    SolarMD's flagship product is their 14.3 kWh battery IIRC [disclaimer: I've got one, itsa very nice... and zef, sure] I recall them assembling around 100 of those a day last year, so "per year" probably meant to say "per day". That meant 100 x 14.3 kWh x 365 = 521 MWh / year. With the upgrade...
