This documentary was made independently and there is no affiliation or payment from any political party or company. We visited Kusile in 2022 on a site visit with engineering students from the University of Johannesburg and I realised that there needs to be an educational video showing the details of how a power station works. Thanks to Eskom for allowing us to film and make this documentary.

They are still using brushes on generator 😮😮😮. It's very tiresome, inspection and maintenance.
We need channels like this to actually give engineers bk their voice,instead of politicians and journalists who actually failed maths
Absolutely... 😂
thank you!
Amen
KUSILE is a ATM for the connected.
Very true especially if you are part of the cartels
i am so proud of this guy, he speaks sense with confidence, i see the next CEO of eskom who understands the process of power generation
Unfortunately Politics will get in the way
Musa Ngwane knows his job,it sounds like he knows everything there as a senior engineer. He is the person who should explain to the county when things are not working.
He should be the minister of electric or the next Eskom ceo.
Great stuff, Mfo ka Ngwane.
Excellent content and greatly presented. As someone who who studied mechanical engineering, I could relate easily. I just don't understand why it's taking so long to complete this project, seems like it is cash cow for certain connected individuals.
Thanks
very detailed. This is excellent! Well done to all involved.
Title should be "How Electricity is NOT Generated in one of the World's Largest Coal-Fired Power Stations"
why is that?
I am proud to have been part of the team that built this powerstation, i was there when Unit 1 was built and left few days after it got commissioned😅 we used to earn a lot of money yoh as Artisans i miss those days
Hope they bring you back
I am so proud of the engineers at Kusile Power Station. This video made me so happy as the talent at Kusile Power Station was showcased. This video proves that there are capable engineers in South Africa. Keep up the good work all technical staff at Eskom!
Very professional and informative
Ae you know, your work station bra yaka danko vir die hard werk sacrificing for your country risking life.
I'm so happy to see South Africans with the ability to explain and take us through the details of electricity production. It shows some progress in education and capacitating ordinary people in running mega-projects. We need to see more of this type documentation in other fields as well.
South Africans are always good, is just the ANC tht has undermined us by importing poor & cheap labour from countries they're in exile and those countries tht said they supported their nonsense freedom struggle cowards. This is a good country more of out ANC government out of power, they're destroyers of good infrastructure built by apartheid government izinja
Love your channel dude! Keep up the great work!!
Thanks a lot
Thank you for this very informative and technically well explained documentary. Hats off to all the dedicated Engineers and Technicians who are keeping this vital infrastructure running 24/7.
some of the time
There are still some very excellent and hardworking people in eskom ❤
Can't wait til' Eskom hires me to work here
@Musa ,very knowledgeable and easy going youngman keep up the good work learnt a lot from this humble engineer!
Excellent presentation of the generation process!... Well done!!
Great channel - thanks for sharing all your knowledge.
Very knowledgeable young engineer .
This is a brilliant video. Well explained and I like the notes that popup every now and then
WOW THATS WAS WELL EXPLAINED, THANKS FOR DOING THIS DOCUMENTARY...
Such a knowledgeable man whose work is spoiled by politics and corruption.
Im glad they being guided by engineering people instead of some marketing person who knows nothing about the plant. Engineers on this clip knows their job because they can explain the process smoothly and in basic terms for anyone to understand.
Definitely
This was a very interesting watch. It would have been nice if you were to ask what their efficiencies are. One of the advantages of supercritical power plants is their high efficiency, but it would be nice to know the actual efficiency numbers.
I'm watching this during load-shedding.
💀💀
Apparently it's not finished yet.
@metalcake2288 i bet its been 200 years😂AnC criminals are unbelievable
The best GM ever! Hands down!!
Well done very knowledgeable and informative.im Zimbabwean and work at a power station 👌
Beautiful content, just what we need in South Africa, our own Megastructures content, very inspiring especially for the kids, students and pupils, Please do more, the biggest dams, biggest sewer treatment plants, Biggest Water Treatment Plant, deepest mine, longest road construction projects and so on .... include drone images too, talk to me for that.
Nice stuff. Very informative and great watch for newly appointed engineer. Keep up the good work!
A very informative video explaining the broad process used in coal fired boilers for electricity generation. There are some discrepancies about the process and equipment though, specifically in relation to Kusile.
Truly grateful for this content 🙏🏾👌🏾
very detailed. This is excellent! well done to all involved
Very informative, thank you very much for this.
All your videos are amazing,I've become the handyman of my friends and family by learning from your channel, I really like this longer format documentary video, super cool and informational, more so than anything you'll find on TV today.
thank you
Thank you for this informative video.
Amazing! Thank you for this.
Nicely done...
thank you Dr for such an informative video.
Biggest problem with Eskom is the high corruption and mafia type business happening inside of eskom.
Excellent presentation and a get to know of the Power plant, thank you.
nice 1 👏🏽
This video was very helpful and important thank you
Great educational content
Thanks for this fascinating presentation, I am not an engineer but really enjoyed this content.
This was awesome.
Insightful video
Very informative thank you 👌🏼
I love it. Nice Content
Excellent content, as one of the guardians I can relate and wish we could have more content like this😊
Excellent.. wow...
48:35 change in phase of water is to maintain and creating vacuum which is very important in the efficiency of the turbines
"How electricity is NOT generated at the Kusile power plant"
Thank you for such an infomative documentary. If possible please may yiu produce another one on broadcasting centres like SABC.
i love informative content like this ;).... keep it up
Fascinating
Well done
Awesome interesting video! Will ovefffer a lot of persepctive to the public!
this is the level i want to become on my job. i want to know everything about it
Great turbine spinners, except the POLLUTION
This is incredible
It should actually say how it is NOT generating power and just keeps on costing us more money
Film a nuclear power station next, please.
While they told us the coal is wet that’s why we have load shedding
can use this as a training video well done
thank you that is the purpose of this video
How the Hell did you get access to this footage this is Excellent😎😎😎😎....
I love it
Interesting that hydrogen gas is used for generator cooling....I believe it supresses arcing as well.
Also, what kind of huge inverter do they have to energize the stator?
If anyone wants to see what power plant control rooms look like, a YT channel called "The Proper People" features urban explorers that have visited closed power stations.... beautiful engineering and classic art deco architecture.
This plant is on another level - however one feels about coal, it's clear that they're doing everything they can to make it more efficient. Someday this plant will be energized by geothermal or fusion, who knows?
Love how it opens.. once it's complete... for 5 sacks.. its gone on long enough. Should have just bought solar panels and batteries..
@sasol we need something like this for the production of petrol from coal
So that we can produce our own 😅
so when will it actually be in full commission? It's been years and still not in full production...
Should hav said "Kusile" is a Nguni word, because in Zulu,Xhosa,Siswati and Ndebele its the same
nice power station, would hate for this to break down or have any maintenance issues
Demineralized water tears the shit out of stainless steel.
Thanks for an informative look at how and where our electricity comes from. Questions -When a power station first starts up, from what you've shown, it would require outside power, yes? If so, where would that come from? Once it is producing "its own power", I assume the power station consumes its own power, where required, yes?
There must be external power during the start-up. This is obtained via the transmission grid by another power station or, if none are available during a national blackout, this power will be obtained from pumped storage stations in the Drakensberg
@@heinvosloo45 Thank you Hein.
52:59 the power station can become a load on the grid and energy flows from grid to plant when plant is not generating
There's a unit out of the 6 units that is called auxiliary unit, it supplies all the electrical component with power...hope that answers you.
@@modisamashishi216 Many thanks Modisa. Always wondered and now I know.
Same as we have here in UK, 3000rpm to give 50Hz. Sadly we are getting rid of all our coal fired stations, not much in the way of effective replacements though 🙄
There actually no need to use the HP, IP and LP stages of having the generator turned.. I work for a company that’s uses methane gas fueled SGT 400 SIEMENS turbines which run at minimum 9600 output power where 2 eskom turbines can be interconnected and run at the same speed. How I hope super heated steam can be done away with and have methane gas generate our electricity NO MORE LOADSHEDDING FOR SA.
Nice thought but as long as we have the ANC interfering in any system things are not going to work like intended. Railways Harbours Post Office Denel you name it and we can see the decay. There was a similsr video about a power station in the U.K.. difference is like chalk an cheese.
Those big gas turbines drive a generator off their output shaft. The hot exhaust gases go to steam generator raise steam for use in a steam turbine to drive generator also. Its called a combined cycle gas turbine power plant. You won't get away easily from steam in thermal power generation.
So this thing of telling us that there’s wet coal is a lie to keep us in Loadshedding
Three crucial units at Kusile, the problematic, unfinished power station beset by fire and the collapse of a flue duct, which is at the heart of the corruption case against former acting Eskom CEO Matshela Koko, are all expected to be back online by the end of the year.11 Sept 2023
“Only 10 years late and 1000% over budget
This is the type of content we need more physics less politics.
Why must coal be supplied to Kusile by truck? Wasn't Kusile built at this location so that coal could be supplied by conveyor belt, as at other power stations?
its a pity that coal is brought in via trucking and the supply is not very close to the plant.
Maybe consider g pin to the rotors to run it syst drive with magneto force.
I would suggest the reason they dont use cooling towers in this application os nevause of a lack of cooling water supply in that location. Also as far as efficiency is concerned, it will take a lot of works power to energise those forced cooling fans 🙄
I work in a coal powered plant!
their hard hats probably costed like R5000 each.
So how is it possible that we use more electricity after 16:00when companies close at that time an all workers are traveling at that time
Evening peak.Every country has a different peak time. Depends on climate, heating or air conditioning demands. Or people cooking food and making hot drinks.
the demand ramps up from afternoon as the millions of people go home to cook and bathe collectively is a huge demand. This is also the time when consumers use most of their electricity, lights, TVs etc...
I'm watching this is stage 5 darkness 😂😂😂
Sir any 2 reasons why coal self ignited???
Coal makes much more sense than biofuels.
How does that tank hold 1.2m cubic meters of oil? That’s 1.2b liters
so much explanations yet there is load shedding.
Kusile is one of the prime examples of ANC corruption, a disgrace, a horror, nothing to be proud of.
Current does not flow through any conductor… it flows around conductors…
100% thank you. Technically electricity isn't generated either but that is the common language.
I think you mean the magnetic field, but current flows through the conductor.
@@modisamashishi216 dc current flows through the bulk cross section of conductors, while ac travels the skin or surface of layer of conductors.
@@simplytrolling6869so you mean I can touch the core of a live conductor and not get electrocuted??? 😮
Modern Powerstation no Cooling Towers
How about you replace those large Generator Brushes, with wifi-eletricity, which they now managed to get really efficient in the KV range at small distance.
Looks like replacement of those brushes would be a great application for it.
WiFi-electricity, what?! You mean induction I guess. These generators have to be as compact as possible, so electromagnets are used as they can be way more powerful compared to permanent magnets. Electromagnets require DC power, induction only works with AC. Adding more stuff on the generator ‘s rotor to convert the AC to DC will diminish it’s efficiency more compared to using carbon brushes.
Could anybody explain why did they build this plant here instead of building it in the Richard's bay Harbour area which would have reduced all costs such as transportation of water consumption
Coal fired power stations are usually built near to the fuel source, in this case, a coal mine. Also, near to water supplies.
It is sitting directly on top of its fuel source. All of the coal exported via Richard's Bay is mined from seams beneath this area. Water is not in scarcity also.
I like this because you say you guys have19 days reserved and now you say that kusile is sitting on top of a mine so which one is it
@@craigfrancisy24u 19 days of mined and washed and processed product, I assume they meant. Not the 100+ years of seams coal ore reserves beneath the surface that I am referring to.
All bullsh*!t this plant cost three times what it should have.
the high cost overruns are unacceptable, but this is a video for teaching purposes of how electricity is generated. Same as in other power stations.
@@ecologicaltime😢 They looking for any opportunity to talk s**t about Eskom instead of understanding the production, the media in this country hasn't done close a job to your presentation which is a tragedy 😢
These machinery used in electricity generation themselves uses electricity, where does the electricity used at the power station come from?

You say typically during the day they run them at 75%,. We shitting with load shedding a lot of the time during the day, they should be running 100% all the time, given they new, older plants run a little less as they would be more prone to break down. Thats another 1000MW to prevent load-shedding during the day and all day.
Simply put, we can't afford to have a fully functional power station. How do u think we'll survive with comradeship...
The grid is complex. Thermal power plants are complex. You can’t run them at full power continuously. Thermal power plants have a sweet spot where they are most efficient, and that’s below the maximum rated output power. When you go to maximum, these extra inefficiencies will heat up all the components. They can only withstand these elevated temperatures for a certain amount of time, before they must cool back down. As this peak output can only be attained for a couple of hours, it’s used for the evening peaks.
