Load shedding

I have to admit (since I don't believe in 'tempting fate') we've been stunningly lucky with the whole load shedding thing. Only lost power once in the last 2 weeks. This w/e we had 100% power while everyone around us suffered greatly. I'm pretty sure my house is on some circuit that nobody ever notices, on a border line between 2 suburbs that both get cuts when we're still up. Let's hear it for happy coincidences.

The silo collapse at Majuba is directly attributable to poor or non-existent maintenance schedules. Associated with the coal from the Majuba mine are appreciable quantities of iron pyrites, an iron sulphide more commonly known as fool’s gold. When left in brackish water (that has some dissolved carbon dioxide in it), the iron sulphides produce sulphurous and sulphuric acid. These acids leach calcium carbonate from concrete, and thereby weaken it. Maybe the contractor also skimped on the concrete mix, using less and/or lower UCS cement than the design called for. Regular turnover schedules (i.e., completely emptying, washing out and refilling the silos) minimises this problem, and acoustic soundness tests will proactively identify the development of weak spots that can be repaired before disaster strikes. Clearly, none of this was done with any degree of regularity or discipline at Majuba, and therefore all fingers should be pointing at the power station’s general manager and its chief engineer.

More broadly, Eskom as a whole is to blame for not pushing the issue of capacity development much more energetically a dozen or more years ago when they first realised that such development would be crucial. Instead, they kowtowed to the ANC government’s insistence that it had more pressing issues to attend to, such as handing out social grants.

I am convinced that there is a spike in motor accidents because of load shedding. Last night, while driving on Zambezi Pretoria (whatever it's called now) parts of it was dark, and I came across three accidents at different traffic lights. All fender benders, nothing serious, but it would be interesting to get hold of some insurance figures.

My power was off in the afternoon last Friday, and Sunday. And again yesterday afternoon. And then there was a heavy storm that knocked it out the whole evening as well. This is getting most annoying...
