An educational documentary about how electricity is generated at Eskom's Kusile power station in the Mpumalanga province of South Africa.
The video take the viewer inside a coal fired power station.
Filmed in October 2022.

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.
Produced, narrated, and directed by Philip Baron.

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?

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

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.

@ethernet0 4 месяца назад
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.
