Where's the MyBB article grilling Chris Yelland and all the other eNeRgY eXpErTs on the inevitable Stage 96 Load Shedding?

Nothing against the guy, but it got a bit long in the tooth reading about it.
 
Let's not get too comfortable, there are still 2 months and a bit of June left. And we haven't really had a real cold snap yet, at least not up here in Gauteng. Still plenty time left for higher stages of LS. Hope it doesn't happen but rather be prepared for it.

Still, it's nearly one month (out of three) that has gone by for winter, which is excellent news.

Actually I'll say it again Chris Yelland said the opposite

Energy expert: Politicians should stop stoking power grid panic

Energy analyst Chris Yelland has urged the country’s politicians to refrain from stoking panic with predictions on the imminent collapse of the power grid.

Not a big fan of the energy experts, especially one of them, but in this case I will stick up for them, when they are being attacked on wrong info.

July is the coldest month in JHB, but CPT has been making up for a loooot more rain, so we will see if thanks to the ocean tides if winter will be mild or cold here in JHB. Our June has been a bit warmer

Warmest winter so far though.

This is for the Norwood / Houghton area of NE Jo'burg (weather.com, usually quite accurate)

Yup, when one door closes in SA, come back and charge more as a consultant.

Good on Cassim for recognising they can't appoint a cadre as a manager of these complex projects (particularly the Koeberg refurbishment):

Cassim explained:
[Against the backdrop of load shedding challenges] I had to weigh up having someone with Jan's experience and what is at stake for Eskom and the country.

Koeberg looked like it dropped output to 600MW for 4 days, looks like they saving water now and only using hydro during peak (not sure Gariep dam level?):

Station build-up for the last 7 days - Eskom Data Portal

This shows how resources were used to build-up the demand over the past 7 days, and it includes both generation and demand side resources that Eskom has contracts with.

System hourly demand and available capacity - Eskom Data Portal

Hourly demand is compared against available capacity, to indicate the amount of surplus/shortfall there was. Available capacity must be matched with the total RSA contracted demand.

Probably dropped it due to the long weekend?

Didn't know you could choose power levels with nuclear? Anyway, why not keep it at 900MW and save diesel, hydro and pumped hydro?

A nuclear power station is the same as coal station in theory. Both use steam to turn generators, one is done by using coal to boil the water, the other uranium :). So they just limit the steam going to the turbines. So they might've needed to do something and thought weekend good time to lower it.
They don't use the dams if there is a possibility of flooding underlying regions.

Yep, they get to ride the gravy train ;)
