[@modelcreationz]

Absolutely... 😂

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

[@kgapholasegadimanebethuel3873]

Unfortunately Politics will get in the way

[@mphilisintonyela]

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.

[@ScissorN]

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

Thanks a lot

[@muzihlungwane5540]

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.

[@denniskhumalo193]

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

[@louisdebruyn4395]

It should actually say how it is NOT generating power and just keeps on costing us more money

[@hothmandon]

Simcity 2000 first taught me the word "power plant" when I was 6 years old. Back then, I thought it was the facility that grew special plants that gave off electricity. That's when I had to learn the hard way that it's more complicated than that.

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.

[@gregorymalchuk272]

38% maximum for a subcritial power station to 42% to 47.5% thermal efficiency for a supercritical power cycle.

[@ThisRandomUsername]

@@gregorymalchuk272 Thanks Gregory! So this power station is not too far behind the most efficient. It's sad that we cannot operate at much higher temperatures to increase efficiency more, but I assume that would need a different working fluid.

[@gregorymalchuk272]

@@ThisRandomUsername Materials science and first cost including cost of materials is what limits initial steam conditions. The hottest superheaters are barely dabbling with austenitic stainless steels. I don't know of any station using inconel or other super alloys in superheaters. One way around this is increasing the average temperature of heat addition to the cycle with double reheat. All of the most efficient thermal power stations are double reheat, Philo Unit 5, Eddystone, Nordylland, Avogdore, Wai Gao Qiao Unit 3, etc.

[@drmanhattanjunior3254]

i fell in love with boilers from starting my new job dealing with a 5mw firetube boiler, i have been running it for five years from water to the final product, what a beautiful feat of engineering i just wished people didn't take this stuff for granted, we would be making a lot better decisions politically.

[@ayandamasina3816]

Excellent presentation and a get to know of the Power plant, thank you.

[@stevengill1736]

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?

[@forevabright]

this is the level i want to become on my job. i want to know everything about it

[@brucemcdonald8529]

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?

[@heinvosloo45]

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

[@brucemcdonald8529]

@@heinvosloo45 Thank you Hein.

[@ecologicaltime]

52:59 the power station can become a load on the grid and energy flows from grid to plant when plant is not generating

[@modisamashishi216]

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.

What an engineering disaster. I subcontracted on this project and re-done some jobs three times over due to other contractors destroying the work. There is a good reason why it went billions over budget and everything is constantly breaking down. Corruption ans sub standard construction work.

[@naughtiusmaximus830]

Demineralized water tears the shit out of stainless steel.

[@01thomasss]

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?

[@ecologicaltime]

its a pity that coal is brought in via trucking and the supply is not very close to the plant.

[@mxolisivilakazi5585]

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.

[@George246-zg1zw]

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.

[@philipread7741]

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.

[@gregorymalchuk272]

The only cost-effective way to use methane for base load power generation is to use the hot turbine exhaust to boil water to drive a steam turbine which provides about a third of the power.

[@Siyanda266]

So this thing of telling us that there’s wet coal is a lie to keep us in Loadshedding

[@craigfrancisy24u]

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

[@philipread7741]

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.

[@ecologicaltime]

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...

[@Thulebeez]

This is the type of content we need more physics less politics.

[@souravsekharnayak]

You have to explain excitator system and grid synchronisation. You blurred the central control room.

[@ecologicaltime]

Eskom did not allow us to show the footage in the control room owing to the law in SA. The control room is considered a key point and not allowed to be in the media.

[@denlsgoulden2307]

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 🙄
