Load Shedding and Eskom Maintenance Festival

Load Shedding 5 to 10 tonight, and probably every night until 2021.

Milnerton 5 to 6.30pm.

Cape Town Load Shedding map. Thank you EWN.

Eskom are talking about getting electricity "barges" (ship) to generate electricity. These will be so much more expensive than just buying electricity from home owners!

There is also a "Maintenance Festival" this weekend. No-one knows how long we'll be off for, but I'd prepare for long periods without electricity, or 2 or 3 periods of 2.5 hours per day being switched off, ie stage 3b / 4 load shedding or worse.

Imagine - no load shedding

The latest news is that Medupi Coal Power Station will only be completed in 2021 instead of 2019, which is already instead of 2018, 2017, and 2016. This means that the time from now till completion is almost as long as the entire build process was meant to take in the first place.

And this means that we can expect Load Shedding to continue at least until 2021. But worse than this, is that at the beginning of the 2020's, 10 GW of existing Eskom capacity reaches end of life, which means that just as Medupi and Kusile are completed, 10 GW of existing capacity will be switched off, and so 10 GW - 10 GW equals zero GW, so load shedding will continue for at least another decade.

Rewind to August 20th, 2010: This is what I wrote on my BLOG at: http://mypowerstation-sa.blogspot.com/2010/08/does-anyone-know-what-r100-billion-is.html

"We are continuously told by government that there's no money, but if we think differently we will suddenly find we have ample money.

"The South African government spent R7 billion on consultants last year to mainly write reports which are never going to be used or implemented. The R7 billion could have bought 700,000 R10,000 Solar Water Heaters. The R7 billion could have paid proper teachers (http://mg.co.za/article/2010-08-18-strike-on-as-unions-reject-govt-wage-offer) salaries.

"One way to find the money is to use the R100 billion for the Medupi power station in a different way. Stop the Medupi new power station development, pay the fines, and use the remaining R70 billion (my guess) for R30 billion of Solar Water Heaters (20GW of energy instead of 5GW of energy), R7 Billion for the teachers, and "change" for: feed in tariffs; zero VAT on renewable energy products; 30% rebates on all solar water and renewable energy installations; tax credits; R10 billion for training and skills transfer from Germany, Spain, USA, Australia, etc."

Now it is 22nd April 2015:

The R100 billion is now R125 billion with no end in sight.

Imagine how many poor peoples' houses could be power stations by now.

Imagine how many rich peoples houses could be power stations by now.

Imagine how many strikes would have been avoided.

Imagine how many more people would have been employed.

Imagine how strong South Africa's exchange rate would be.

Imagine how low our Inflation Rate would be.

David Lipschitz Representing SAAEA at the CSP Conference in 2015



Yours truly at the CSP (Concentrated Solar Power) Conference at the Southern Sun Cape Sun Hotel today. I represented the SAAEA, South African Alternative Energy Association where I am an honourary life member and adviser.

This card also says “Press” on it which confirms my status as a journalist. Besides my being a member of the Cape Town Press Club since last year.

I spoke to the organiser when leaving the conference tonight and he said I asked good questions.

And today, the Cape Times has a letter from me on behalf of another organisation, the GCTCA (Greater Cape Town Civic Alliance) where I hold the Energy Portfolio Leadership. The letter is about Carbon Taxes.

Is R100,000 a lot of money?

A friend installed a solar PV system for R100,000, which uses partly solar photovoltaic electricity from the sun, partly batteries, and partly Eskom.

Was the R100,000 investment worth it?

In summary, the cost is R21,820 per annum instead of R29.591 per annum, but there are some assumptions, so read on. And that's just in the first year. In the second year the cost is R22,569 instead of R33,327.

Here are some calculations:

Besides the security of supply advantages and no load shedding advantages and reducing one's carbon footprint advantages and the advantages of all one's friends wanting to visit and see what one has done and the advantages of being able to continue working from home, assuming one does that, there is also a saving in what Friend has done, especially once rates go up in July 2015.

Some calculations:

R100,000 is R1,338 per month at 10% over 10 years. Or R16,056 per annum. Using the Standard Bank calculator at https://www.homeloans.standardbank.co.za/servlet/com.sbsa.sbhl.bondcalc.business.MainCalcServletInternet?page=Main_MonthlyRepayEntry

Note that the R2.10 per kWh tariff that I have used in the following calculations is the City of Cape Town Electricity tariff assuming a 13% increase in July 2015.

If Friend used 32 kWh per day and now uses 6 kWh per day in summer and he used 45 kWh per day in winter and now will use 9 kWh, then assuming summer is 6 months and winter is 6 months, then :-

32 kWh * 183 days + 45 kWh * 183 days = 5,856 kWh + 8,235 kWh = 14,091 kWh * R2.10 per kWh = R29,591 per annum.

6 kWh x 183 + 9 * 183 = 1098 + 1647 = 2,745 kWh * R2.10 per kWh = R5,764 per annum.

So he was paying R28,182 per annum and is now paying R16,056 + R5,764 = R21,820, which is less than R29.591.

He also switched to gas for part of his cooking, but he still has R7,771 to play with before he breaks even. And that is only in the first year. In the second year when prices increase by 13% again, his savings will be even greater as his cost will be R22,569 instead of R33,327.
