Our electricity supply is becoming more and more precarious. Eskom should be able to supply 42 GW of electricity but on a regular basis it can only supply only around 30 GW. The grid infrastructure is overloaded which puts a large burden on transformers which are reaching end of life in half of their usual life, ie 12 years life instead of 25 years life.
Our grid itself is behind with maintenance and many of our power stations are already beyond end of life and are being kept running, but who knows when they might break.
Our best coal is exported and we use poor grade coal in our own power stations, and everyone knows what happens to their car engines when they use poor grade oil in them!
And then Eskom have shown since Koeberg was built in the 1970’s that they cannot manage the build of new power stations which usually take years longer to build and are usually 50 to 100% over budget, yet we continue to allow this.
With all this damage being done to our system, willingly or unwillingly, we are placed in a dilemma.
What to do when the power runs out
If our electricity supply is suddenly switched off the following will happen very quickly:
- Most people are meat eaters. They won’t be able to cook their food, unless they have reserves of braai (BBQ) wood. They will get hungry.
- Backup generators will kick in. Many of these only have 16 hours of reserves which is seen as more than sufficient under normal circumstances, e.g. expected power failures of 1 to 4 hours a day.
- After 16 hours the Backup generators will stop working.
- Petrol pumps won’t be able to operate because they rely on electricity.
- All transport will stop within days. There is only 4 days of food in our supply chain, and without transport, our just-in-time systems will not be able to be replenished. And there won’t be transport to get diesel to our backup generators.
- Water pumps won’t be able to operate because they rely on electricity. So we will be without water very quickly. We won’t have drinking water and we won’t be able to flush our toilets. And we can survive for 2 weeks without food, but we cannot survive for 2 days without water. How many people have got water backup at their houses and businesses?
- Within days, fridges and freezes will get hot and food stored in them will be useless.
- Within one to four days there will be a complete breakdown in all forms of civil obedience. Hungry, desperate people, who normally aren’t violent, will suddenly become violent as they search for food and water.
South Africa is one of the very few countries in the world with ample raw materials, eg coal (for power stations and coal to oil), off-shore gas, bauxite (for aluminium), iron ore (for steel), platinum, more than enough space for food if we use it wisely, more than enough minerals for our own companies to manufacture and for us to be a net foreign currency earner, i.e. more exports than imports. We have more than enough people to do the work.
The only thing missing is ELECTRICITY. Eskom can supply about 30 GW, but South Africa’s real demand is closer to 100 GW. Eskom and the government (DA and ANC) holding onto the power they have in their small electricity incomes are missing the bigger picture of how electricity can change South Africa’s economy.
Solutions at hand
So should we care? And what solutions are at hand?
Renewable Energy isn’t only about electricity. It is also about water, about food, and about self sufficiency. So renew your energy and keep yourselves secure.
