As I write this we actually have mains supply power. According to our neighbourhood WhatsApp group it’s because a dignitary is attending a function at a local sports club. By dignitary I mean someone with political clout. That way they can pretend that all’s well in the power supply situation when the reality is 18 hour power cuts every day. We are in this mess for several reasons, the main one being we have possibly the world’s cheapest power at US3c a unit (kWh). Until very recently it was 1c.
It wasn’t always that way. Back in the days when we were using real US$ and nothing else it was around 10-14c a unit and power was plentiful. We could import what power we needed from Mozambique and South Africa and even if the rest of the economy was a mess, which it was and still is, power was there if you needed to use it. Then in 2016 the government decided to introduce another currency called the “Bond dollar” which locals quickly nicknamed the “bollar” or “zollar”. The government insisted it was equivalent to a US dollar and was backed by a bond from the Egyptian Afreximbank and it was there to reduce the problem of small change. It was a lie. There was no bond, those who could withdrew their real dollars from the bank and those who couldn’t watched as the value of their accounts was whittled away by the informal market exchange rate. Eventually the government admitted that the bollar was not equivalent to a US dollar and pegged it at 2:1. The informal market ignored it and the rate soared to 12:1 before the government made it illegal to trade within the country in anything but bollars which were now called new Zimbabwe dollars (though we have yet to see any actual notes). The official exchange rate has now risen to around 14:1 which is why our electricity is ridiculously cheap. We were informed earlier this year that our bank accounts that had been in US dollars were now in Zimbabwe dollars – and so was our real money stolen.
We now owe US$73 million to the power utilities in Mozambique and South Africa with no real hope of paying it back and getting ourselves reconnected (not surprisingly they refuse to continue to export power to us). We need to import power because local thermal generators have been badly neglected because they have not been charging enough for the power (the government regulates power and fuel charges). This means that maintenance has not been done and our main source of hydro power, Lake Kariba, has been over-utilised beyond its design limitations. To compound the mess last season there was poor rains in the main catchment area in north-western Zambia and Angola.
The effect of lack of maintenance cannot be over-estimated. Apart from effeciency loss in old switch gear and old machinery (turbines), transmission efficiency is also affected. Insulators get covered in dust, rain turns the dust to mud which then causes shorts to the supporting structure which heats and cracks the insulator. Local losses are around 12% (I’m told the internationally accepted level is 7%).
The local power utility, ZESA, has embarked on a programme of power cuts or load shedding as it’s known locally. Alternative energy suppliers’ businesses are booming. The Reserve Bank estimates that the diesel fuel import bill has jumped 20% since the power cuts started as people and businesses buy it for their generators – money that could have been put into importing power in the first place.
It doesn’t take a huge imagination to realize what the consequences of these draconian power cuts are going to be. Some of the bigger mines import their own power directly from South Africa but the smaller ones, which apparently are given priority, have to make do. Farmers irrigate their crops in the dead of night when the power comes on, usually between 10 p.m. and 5 a.m. but this is often not long enough for a full cycle and I’ve heard of farmers abandoning their winter wheat crops which have demanding irrigation requirements. Tobacco seed sales were down 30% in April but this was as much to do with the government reneging on it’s promise to pay a proportion of the sales in hard currency as a lack of power. The early tobacco crop (tobacco is a major foreign currency earner) does require irrigating and supplementary power sources for the irrigation will likely make an expensive to produce crop excessively so.
Cell phone connectivity is now noticeably reduced as service providers have to rely more on backup power sources – usually diesel generators and the cost of airtime has gone up considerably.
We recently had six days with no power at all – just us and a neighbour across the street. Marianne went into the local ZESA offices to see whom she could get to come and have a look. A technician duly arrived and walked around the property then said he’d go and have a look at the sub-station (which supplies the suburb) and nothing happened. The next day the neighbour tried with no success. By now we were having to throw away food as our solar system couldn’t cope with running the fridge, deep freezes and other appliances and borehole pump 24 hours a day. So I went along to the offices, fully prepared to have to pay a bribe/sweetener to get something done.
I asked for the local manager with whom Marianne had spoken and introduced myself by commenting that we had more in common than he realised – we are both going bald. He laughed and I knew we were off to a good start. After explaining the problem I asked him what the future of our electricity supply was. Without saying anything he pointed to the ubiquitous portrait of the President, E D Mnangagwa, that seems obligatory in government offices. I replied “Please don’t point to that picture and tell me Zimbabwe is open for business”. The occupants of the office found it hugely funny. The slogan “Zimbabwe is open for business” was widely used by ED, as the President is known, in his election campaign.
“Are you and engineer?” I asked the manager.
“I am” he responded.
“So”, I asked him, “what happens when the water level in Kariba gets too low to be used for power?”.
“We turn it off” he replied.
“You mean the whole country?”.
“The whole country” he confirmed.
“Unless we can find some money to import some power. But that’s unlikely to happen so long as we have the world’s cheapest electricity?” I responded.
He nodded to E D’s photo without commenting.
That afternoon our power supply was restored and I hadn’t needed to part with any money – sometimes engagement is all it takes.
I don’t expect that the whole country will be turned off anytime soon. Certain areas in Harare, where we live, seem to be exempt. The grids surrounding the main hospitals and the President’s residence don’t get power cuts. A friend who lives close to the state controlled broadcaster, ZBC, never gets power cuts. Another friend who lives in a rural part of Zimbabwe in the east is on the same line as a senior ZESA executive never gets cuts either. That said I’ve told Marianne that we need to expect ever more draconian cuts – we don’t live near anyone or anything of political consequence.
Some four years ago I was living on a farm close to where I work. It was for me the perfect existence – close enough to town to be convenient but far enough away to benefit from the peaceful countryside. Whenever there was a thunderstorm the power went off and could take several days to get it fixed. I got fed up and bought a small solar system to keep the fridge and deep freeze running. I’ve always been a bit of a geek and liked the idea of a bit of independence from the grid and yes, I got a bit of a fuzzy warm feeling that I was doing something good for the environment.
The system worked well and it was upgraded by two panels when we moved into town. Then earlier this year as the load shedding was introduced the original lead-acid batteries had run their life and needed to be changed. It was evident that the power cuts were only going to get worse so we decided on another upgrade. Foolishly we bought locally manufactured batteries which only lasted 3 months but at least we could pay for them in local currency. The company that sold them to us did admit there was a problem and replaced them but we’d decided to go with an initially more expensive but much longer lasting lithium battery. Yet more photovoltaic panels were added with our closely guarded US dollars and now we have a nearly-off-the-grid system. It’s OK if we get a few hours of mains every night to charge the battery but if it gets to the stage where we’re completely cut off (no important neighbours to please) we are going to have to think of upgrading yet again. It will be money that could have been spent on a couple of really good holidays.
The area where my nursery is has been relatively unaffected by power cuts. The research farm where I used to live is on the same grid and likes to claim some responsibility. I think it’s mostly due to the military barracks just down the road – can’t annoy those that keep the government in power now can we? Whichever it is it’s unlikely the situation will last so just before the recent slide in the local currency I invested in a solar powered borehole system whilst I had the money. Fortunately I have a young friend who has a qualification in solar systems and he helped me put it in by doing the design work whilst I did most of the welding of the structure. We did have to wait a month to get the electrics hooked up as the electrician was simply too busy doing other installations. In a rare moment of common sense the government has removed duty from solar panels and other associated equipment so those who can afford it are scrambling to install systems.
So far our system works fine, weather permitting. It cannot pump all the water we need so we are still reliant on getting at least some power to keep the water tank full and if the power goes off during the day, as it sometimes does,
there is a generator but it can go through 25 litres of diesel a day which of course is in short supply.
The price of power has recently gone up by up to 300% but it is still ridiculously cheap especially since the exchange rate with the US dollar has started to run again. There is no obvious way out of the mess.
A letter to America
5 02 2023Hi Robin,
Our weather has become increasingly erratic over the last 15 years or so. I put it down to climate change. Right now we are in the middle of a relatively normal rainy season. That means that the ITCZ (Inter-Tropical Convergence Zone) moves over the country and it rains – quite a lot. Most of our rains happen from mid November to the end of March which in Harare means some 700 to 800mm. The rain can be quite intense – we had 75mm (3 inches) in several hours last week which meant all the rivers around town were up and one of the reservoirs that supplies town was spilling. As a country we’ve had good rain for the last 3 years due to the la Niña effect though it has been quite variable over the country and Harare, which is in a high rainfall area, received less than average. We are due for a drought and I see that there is a el Niño predicted later in the year which is a reliable indicator.
There’s rain around as I type this and yesterday afternoon we had quite a storm with high winds and hail and of course the power went off. It’s still off but we are geared for this eventuality and have solar panels and two lithium batteries to get us through the night. Power outages for other reasons, mainly incompetence and over-use of Lake Kariba as a hydro source, are common so everyone who can has a solar backup plan. Solar water heating makes a lot of sense in our climate so we have three solar heaters, one for us, one for the cottage tenants and one on the domestic employee’s rooms. In the cloudless, hot days of August and September the water can easily boil.
I see your weather has been erratic too. Mt Washington in the north-east of the USA hit a record -70C a few days back and Europe had an unseasonably warm Christmas. It seems that California has had some heavy rains too; the default weather app on my new iPad is set to the Apple headquarters in Cupertino and they had flood warnings out recently.
Planned, and I use that word loosely, power outages are called “load shedding” in this part of the world. Towards the end of last year it was announced that Lake Kariba, which is our major source of hydro power, had got to it’s minimum level permitted for generation due to over-use by the Zimbabwe power authority and load shedding would become a daily occurrence. We have another major thermal power station at Hwange in the west of the country but it has become a byword for mismanagement and cannot take up the shortfall. We also import a lot of power from Mozambique and South Africa but have managed to get into a lot of debt so the aforementioned countries are fed-up and restricting our supply. South Africa has its own power supply issues (again due to mismanagement by the state-run utility) and is also imposing load shedding but at least it sticks to a schedule. In Zimbabwe the power generally goes off in the suburbs about 6.30 a.m. and comes back on around 10 p.m. Businesses are not exempt either and incur heavy costs due to diesel generators. It’s not unusual for some to run just on night shifts.
Our swimming pool was an early casualty of the power cuts. It’s essential to keep the filter running which the solar panels can do on a sunny day but those are rare in the rainy season so it’s more green than clear these days. Marianne was muttering about the cost of more chemicals to try and clear it. I pointed out that we could always fill it in but it wouldn’t be a cheap procedure and then we’d lose some 70,000 litres of stored water that would be very useful in a drought. We have decided to live with it being more green than not (it is covered over in winter when not in use).
The book you asked about is, I think, “The Shackled Continent” by Robert Guest who was an Africa correspondent for The Economist for a number of years. I found it fascinating and very insightful. Maybe I should read it again.
My business muddles along. I have a lot of outstanding debtors and it’s not so simple as insisting that they pay up front for their orders. I hate having to get nasty but it may eventually come to getting professional debt collectors in as I need to get the money to pay for imports of the coir “peat” raw material that we use to grow the seedlings. I obviously cannot use Zimbabwe dollars but fortunately I did invoice in US dollars which once again is becoming the currency du jour. The government is still trying desperately to keep the local dollar alive but with an official exchange rate of 740 to the US dollar compared with a “parallel”, i.e. street, rate of 1,100 to the dollar, it doesn’t have much of a chance. The local currency is still used, and has to be offered, as a payment method but most outlets make it very attractive to use the US$ by offering massive discounts . Government departments don’t do this so get paid almost entirely in local currency which means they are perpetually in financial difficulties – hence the disastrous state of the power supply, roads, rail links and anything else they are involved in. Am I making sense?
The government is also trying to stifle speculation on the currency markets by lending money at vast interest rates, 110% in November 2022, which makes doing business very difficult and one of the reasons that I use to explain why my business is so flat. The other is the proliferation of competition, often informal, which cut lots of corners allowing them to undercut my prices. Their quality is dismal but people either don’t care or see it as an acceptable consequence of the cheap prices. My prices haven’t changed in four years despite the rising costs of inputs in real (US dollar) terms. It doesn’t make for attractive business. Curiously the construction business is booming with cluster homes (small, single level apartments – several to a property) and other developments being built throughout the suburbs. Quite where the money is coming from I cannot ascertain – but in an economy as moribund as ours it’s almost certainly dirty.
Yes, us Zimbabweans are a resourceful lot and I guess in that respect Diana remained true to her heritage. My workroom/office is full of junk that I cannot throw away just in case I find a use for it in years to come. It must be a hold-over from the days when Zimbabwe was Rhodesia and under sanctions so nearly everything that could be was recycled. It’s probably an attitude of my generation rather than today’s “youngsters” – I drive past a municipal rubbish tip on the way to work and there’s never a shortage of trucks pulling in to offload. I suppose people do make a living out of recycling here though it’s not as fashionable as in the developed world. An elution plant (recycling gold from electronics) has recently been constructed at the former rubbish dump. It’s also not unusual to see carts being pushed around the suburbs and having one’s gate bell being rung by the owners looking for scrap metal.
I guess our “big” news for this year is that we’re going over to the UK in May to attend a rock concert! I’ve never been to one as standing for a long time in rowdy crowds is obviously not possible for me but this is Mike & The Mechanics who are not as popular as they used to be so seating is an option. Time to tick off the bucket list.
Then we are going to stay on the Cote d’Azur with an old girlfriend and her husband for four days. Apparently we’ll be quite close to St Tropez. Marianne is keen to go and see how the ultra-rich live but I may give it a miss. Really looking forward to it and we’re brushing up our rudimentary French in anticipation.
Well, on that positive note I’ll sign off and wish you all the best for this year. Forget the snow shoveling, go skiing and may it be exceptional.
Ciao
Andrew
