Greetings from Durban, South Africa, where it can get very hot and humid (apparently 44 degrees and 80% humidity on Christmas, although I wasn’t here for that) and the thunderstorms are pretty impressive (fork lightning is badass).
Naturally occurring electricity is one thing, but the manmade power grid is another. South Africa’s power supply is currently going through the biggest disruption for a number of years, with “load shedding” across the country – rolling power cuts, affecting anyone who hasn’t got a backup generator (and many of the wealthier households do). The state-owned power company, Eskom, is cutting off power to entire suburbs or cities at a time, trying to prevent a devastating national blackout where no one can get electricity at all:
Eskom’s Andrew Etzinger says the power cuts are necessary to avoid a countrywide blackout.
“The worst case scenario is a national blackout which we seen in other countries over the last couple of years which happens when the entire grid is lost and no customers are supplied.”
He said if that happened in South Africa, it would take around two weeks to restart the grid while the entire country is remains in darkness.
How did things get to this stage? Again according to Eskom, “over-burdened power plants, the neglecting of refurbishing infrastructure, poor coal quality, heavy rains and an over-reliance on diesel are among the reasons for South Africa’s current power crisis” – pretty wide-ranging there, and presumably most of the fault lies with Eskom itself, or with the government. Eskom do go into more detail on their current problems in that article, making it a good place to start for more information (also another article here). President Zuma, on the other hand, has pointed the finger at apartheid:
While everything from the second paragraph onwards is obviously true, it’s facile to blame a system which ended 20 years ago, especially given the various failures which Eskom have acknowledged. Electricity is an indispensable part of modern living, and an unpredictable supply can lead to all sorts of other issues for households and businesses.
Anyway, it does make you take stock and think again how lucky we are to live in New Zealand, where electricity is reliable and affordable (not to mention mainly renewable), and the market system appears to work reasonably well.
