@@JBG-AjaxzeMedia not really. The miners were very skilled and did most of the work. I just marked out the centre line, level line and they knew the blast pattern. Some blasts weren’t very accurate anyway as the rock (slate) varied in hardness, so you had to go back and take a bit more out anyway. Putting stuff in (concrete, steel, machinery) was much trickier!
@@mnikhk During a black start only the powerstations are being fed electricity. So you don't need all that much power output, but the problem is that you do need that power output. That is the chicken-and-egg problem of starting a power plant. You need power to start the power plant before the power plant produces any power. Hydro is often used to provide the black start capability to electricity grids, because starting it up can be as easy as opening a (very big) valve and it can ramp up to full output quickly. So this plant and others like it provide the power to start other, bigger, plants like natural gas, and then finally big coal plants. As the power output from all of them slowly ramp up the power is then diverted to the actual consumers in the grid and area by area power comes back on.
I remember begrudgingly going on a geography field trip with my school to this place, back in the mid 90s. And now, here I am, over 20 years later, watching a TH-cam video about the same thing, willingly and happily.
yeah, kids are literally stupid. I remember I absolutely hated learning in school and now all I do for fun is learn about things. Every day is filled with regret over the countless opportunities for education I let slip by me. But that's life for ya, you don't know what you have until it's gone.
As a costarican (my country produces 90% of electricity by dams) i cannot imagine pumping up a reservoir just to cover on demand peaks, but as an engineer, I'm way more impressed of stopping such a huge flow of water in 10-30 seconds. The guys who designed the relief valves and system surely had the most funny and stressful job of the project.
I mean, tbf most major European nations could happily have dirt cheap electricity available in huge quantites but that wouldnt help with climate change.
I live in Quebec, we produce so much damn hydroelectricity we could pull the plug on half of new york if we wanted. It's also state owned so we have the cheapest electricity in north america and everyone profits. We got 681 dams
Hydroelectricity is genuinely such a phenomenal invention. Here in Quebec, the entire province runs on hydro, powered by the St. Laurence river for major areas like Montreal and surrounding suburbs.

Thank you, Tom! I watched this video just a week before my Advanced Human Geography paper for CIE A Level and one of the questions I was given in that paper was: "‘Producing energy from renewable resources is not the answer to meeting energy demand.’ How far do you agree?". I mentioned this lake as one of the case studies to support my argument. I got an A grade in Geography and I got my best mark from this paper.
Niagara Falls has something kind of like this, only they don't need to use pumps to fill it. They have large reservoirs, and and night they divert water from upstream into the reservoir, which they can draw down during the day. This helps with higher daytime electrical usage needs, but also helps with daytime tourists, as they don't want to divert so much of Niagara Falls to use for electricity that it disappoints tourists.
Wordsnwood (Art Mulder) there was a proposal to build a system similar to the Niagara falls one in the Scottish Highlands but it was Lobbied out of existence by people concerned it would spoil the view for tourists, the same way every big renewable energy plan is
Wordsnwood (Art Mulder) of course! People find it very hard to believe that they are able to divert the water entirely, completely draining Niagara Falls, and it’s completely true! They’ve done it before and there’s talk of them doing it again.
I went here a couple of years ago and the sheer size of the place amazed me. The valves are absolutely enourmous and to think they can move so fast at a moments notice is incredible.
If this video has piqued your interest in water hammer and how, in large systems like this especially, it needs to be mitigated there's an amazing video by Grady on the youtube channel Practical Engineering that is wonderfully informative!
I had heard of water hammer, I had also heard of hydroelectric batteries before, but I never thought about the challenges that the combination of those two would pose... Anyways, truly fascinating!
there was a huge dam in russia that was blown apart by water hammer. they shut the valves below the turbines, and the huge pressure spike caused the turbine to blow out it's bearings and shoot through the generator house. i believe it was stopped from draining it's entire reservoir by a coupe of guys that managed to shut a backup valve at the top of the dam.
To whoever wondering; when I was there they told me the reason it’s underground is because it is in Snowdonia national park, which means they have to build in a way so it won’t take away the beauty from the area. The solution was to dug it down, and it is the largest underground space made by mankind. The largest hole, or space if you will, inside the mountain can fit Salisbury Cathedral in it!
This has to be the immediate way to solve the intermittency problem of windmills and solar. It's easily understood, and notwithstanding the enormous engineering challenges (which are at least well understood) it's do-able right now. Scotland and Wales surely have a lot of potential here to boost their economies.
That is a proper power station though, not just a Peak Load Balance Station like Dinorwig is. It is a damn sight bigger too. Neither of them are batteries though.

All electrical systems - no matter whether connected to the National Grid or independent require regular expert mechanical maintenance (or do you think nuclear power stations, solar panel farms, and wind turbines look after themselves?) As for the water level - it's Wales! I don't think I've ever visited Wales and it's not rained at least one point in the day. Considering it's described as 'a rainy bit' of Wales, I should guess that it is one of those regions of the British Isles that receives a peculiarly high degree of rainfall (like Eskdalemuir in Scotland and practically all of Ireland. It's quite probable that, unless climate change really makes significant changes to the British climate on a permanent scale (ie, we turn into a desert or frozen tundra), then I think we can be fairly sure that the liquid water level in this particular 'battery' will be just fine. Also, I'll be surprised if the water in the lake used in this battery is not more, much much more than required for daily operations. I doubt very much that the lake drains completely with each manoeuvre. So, more than enough water. Also, don't be such a downer. You sound like my son, for goodness sake. Think about your mum and dad for a moment and how it feels for them to hear you being so negative about nothing at all. It drives us mad.
I've recently watched one of your older videos (The Problem with Renewable Energy (and how we're fixing it)), and the new video fits so seamless to the message of the old video, except for the fact, that you've predicted a completly diffrent solution how we should deal with storage problems and renewable energy. Anyway, great video, keep going!
*+thegreenmadow* The thing is that it takes minutes for a hydroelectric dam to kick in and start generating power, by which point the grid imbalance would have already tripped breakers and caused issues, which is what the large spinning steel turbines help mitigate. One possible solution is to have computerised batteries handle the spikes of energy consumption in between the times while the hydroelectric dam valves open or close (which takes time to mitigate the water hammer issue).
Electric Mountain takes like 10-30 seconds to kick in, as per this very video (when I went to visit they said it averages at 18 seconds) and provides power at such a level that its use is easily predicted and accounted for.
What I love about this power station, is that for other renewable sources, like wind and solar, they're not always constant, but in north Wales, it's always raining at least three times a week
Anyone else hear of this through Citation Needed...gotta love learning things from every Tom Scott series. Anyways, great video, and an amazing power storage system.
Never get bored of this - been a number of times and will return once it opens again in 2019 - always fascinates me. Thank you for giving me another insight into its workings!
There's something like this in Missouri USA called the Taum Sauk Hydroelectric Power Station. It's used for the same purpose in very nearly the same way. Owned AmerenAE, if I recall. Years ago there was a catastrophic failure of the upper reservoir which caused the devastation of homes and an entire national park. It's an interesting tale.
Here I am on a lockdown Saturday.... Been "asked" by my other (better?) half to paint..... Coming up with more feeble excuses every minute as to why I can't..... All because I have been sat watching this channel continuously for the last 5 hours! 5 hours! Mr Scott, you are a legend and a true joy to listen to (a cross between David Attenborough's soothing voice and Johnny Ball's enthusiasm). Thank you!
*+Tom Scott* Wow Tom, thanks so much for sharing this. I love this stuff. You keep sharing little bits of what keeps our world running and although this is in the U.K. it's still relevant to other nations of the commonwealth (New Zealand, in this case), and I just love the engineering of such spaces. My dad (deceased) worked on the Roxburgh Dam here in New Zealand and I have visited a lot of hydro projects here. From a time when governments built such places and we, as taxpayers and citizens, were proud of such achievements. Now corporations make money off the back of such efforts and I dread to think what would happen if they were left to give a maximum shareholder return at the lowest price they deem possible. (sigh)
Been there, the whole area is amazing, the mountains, the lakes, the old quarries, there is another one of these just down the road at Bleanau Ffestiniog
A couple years ago we went on holiday in Wales and stayed in Llanberis which is right next to electric mountain. It was a really cool experience in there and the insight came in use when I was studying A level geography.
We used to have a cottage on the other side of this mountain, near Marchlyn Mawr lake. One time we went for a walk up that way and got kicked out quite quickly by security, I'd imagine the lake can be quite dangerous when the water is being drained.
Wait wait wait... the British electricity grid works because of a battery owned and operated by Engie ? But... Engie is the former GDF, aka the French public gas system (that got privatised for some obscure reasons), and it is still partially owned by the French government. So the British grid is owned by the French. After centuries of war and diplomacy, we finally did it, we own England ! Victory at last !
Well after Britain saved French ass twice in a century, the least France can do is to pay back Britain in the form of the LARGEST BATTERY EVERRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRR
The same principle as between Kochelsee and Walchensee in Bavaria, just that those are natural lakes 200 meters elevation difference and started to operate in 1924. Now imagine excess solar or wind energy to pump the water up.
I remember going here as a kid! We were meant to go up mount snowdon that day but the weather didn't allow it and thank god for that! This place was way more awesome than some mountain!
Plane geek 118 it does, back in the 80’s and 90’s when as the guy said, there was only 4 odd channels on tv, something like a Christmas episode of eastenders would get insane viewer numbers of like 20 million and so on, and when that ends, 20 million kettles turn on and I remember back in the 90’s a few times that the power would go out (maybe only 10-30 seconds) or you’d see the lights flicker, because a popular show on tv had just finished and half the country was making a cuppa!
I’m sure it still does now too but viewer numbers don’t reach what they used to as there’s so many channels now plus you can record shows etc meaning it’s all spread out more! I’m sure it still peaks during soap advert times but not as intense as it used to be
I remember someone said Britain had a assive power down when all the nation turned on their electric kettles at the same time. Thats the most brtitish thing i've heard
Never knew this existed, how does it compare output wise to Cruachan Power Station? These designs have to be a major part of the solution to our power needs in the future. A dam at height and a generator and pond at the bottom,you could even use excess solar / wind generation to pump the water back to the reservoirs at times of low consumption! They can also be made at various scales depending on the geography
There is a slight catchment in the above reservoir of Marchlyn Maur, however they don't want to extend that catchment area in case it effects the surrounding environment, keep in mind this is in Snowdonia National Park which has multiple rare species of flora and fauna which rely on the specific climate, which includes the Snowdonia high amount of rainfall, to divert water and deny it for wildlife on the rest of the mountain would be detrimental.
We have a similar facility in Czechia. It's called Dlouhé Stráně. I've been there two times. Once on an excursion and once just on a hike and this place just blew my mind. Such a marvel of modern engineering. Also notable fact is that is's built in the middle of protected landscape area, so most of this aparature is very well hidden underground. The only visible parts are the lake on top of the mountain, the dam down in the valley, an entrance into the underground facility and unconspicuous mountain hut, which is the administration building and powerlines. Even the electric lines are painted green and the isolators are made of clear glass so they don't disturb the landscape as much.
"...this rainy bit of Wales". Well, that narrows it down a little. :P

@@demawoods2679, Welsh. Things in Wales tend to be dual language.
@@demawoods2679 Welsh/Gaelic i presume.
@@benoitbvg2888 Welsh is not a Gaelic language. The Gaelic languages are Irish, Scots Gaelic, and Manx. Welsh is a cousin: the other side of the Celtic family, along with Breton and Cornish.
I was expecting a lake with metal on the sides and an electrolyte liquid in the lake

This an absolutely spectacular video Tom. It is both really cool and really educational. Please never stop making videos like this.
I remember when I was 6 my dad took me here when we were on holiday and I remember how amazed I was because I had no idea this was possible that mountain completely changed my life and got me so interested in engineering it made me become an engineer and amazes me still today.
It is north of snowdon and the little town of llanberis. It is also next to the national slate museum if anybody wants to take a look

If you ever feel useless, hold a minute of silence for all solar panels in Britain.

You don't need direct uv rays to produce energy, although you can produce a lot more for that matter
Hell yeah, huge battery, and kind of never degrades as long as you maintain the mechanicals and the water level.
And all in a country a load of people dunno abt
Erosion?
You could say the same for your car battery if you kept topping up the acid.
All electrical systems - no matter whether connected to the National Grid or independent require regular expert mechanical maintenance (or do you think nuclear power stations, solar panel farms, and wind turbines look after themselves?)
As for the water level - it's Wales!
I don't think I've ever visited Wales and it's not rained at least one point in the day. Considering it's described as 'a rainy bit' of Wales, I should guess that it is one of those regions of the British Isles that receives a peculiarly high degree of rainfall (like Eskdalemuir in Scotland and practically all of Ireland.
It's quite probable that, unless climate change really makes significant changes to the British climate on a permanent scale (ie, we turn into a desert or frozen tundra), then I think we can be fairly sure that the liquid water level in this particular 'battery' will be just fine.
Also, I'll be surprised if the water in the lake used in this battery is not more, much much more than required for daily operations. I doubt very much that the lake drains completely with each manoeuvre. So, more than enough water.
Also, don't be such a downer. You sound like my son, for goodness sake. Think about your mum and dad for a moment and how it feels for them to hear you being so negative about nothing at all. It drives us mad.
I've been there and I didnt even realise until a minute in wtf that brought back some old memories

I've recently watched one of your older videos (The Problem with Renewable Energy (and how we're fixing it)), and the new video fits so seamless to the message of the old video, except for the fact, that you've predicted a completly diffrent solution how we should deal with storage problems and renewable energy.
Anyway, great video, keep going!
*+thegreenmadow* The thing is that it takes minutes for a hydroelectric dam to kick in and start generating power, by which point the grid imbalance would have already tripped breakers and caused issues, which is what the large spinning steel turbines help mitigate.
One possible solution is to have computerised batteries handle the spikes of energy consumption in between the times while the hydroelectric dam valves open or close (which takes time to mitigate the water hammer issue).
Electric Mountain takes like 10-30 seconds to kick in, as per this very video (when I went to visit they said it averages at 18 seconds) and provides power at such a level that its use is easily predicted and accounted for.

Weetile What, did you unsubscribe? He's still releasing music regularly
I know it's a quote, but the sun is more akin to a generator than a battery.
You could make a religion out of this...
What I love about this power station, is that for other renewable sources, like wind and solar, they're not always constant, but in north Wales, it's always raining at least three times a week
Surely seven times!
Anyone else hear of this through Citation Needed...gotta love learning things from every Tom Scott series. Anyways, great video, and an amazing power storage system.
Dang. All it takes is one video to remind how freaking awesome Tom Scott is.
I love how you can see how cool Tom feels when he says “Electric Mountain”
Discovered your channel last week been watching the backlog since. Amazing stuff really interesting
Never get bored of this - been a number of times and will return once it opens again in 2019 - always fascinates me. Thank you for giving me another insight into its workings!
One of my favourite channel on TH-cam. Thank you
Grady from Practical Engineering has some great videos on Water Hammer!
This looks like the coolest place on the planet!! I want to work there!!!
There's something like this in Missouri USA called the Taum Sauk Hydroelectric Power Station. It's used for the same purpose in very nearly the same way. Owned AmerenAE, if I recall. Years ago there was a catastrophic failure of the upper reservoir which caused the devastation of homes and an entire national park. It's an interesting tale.
Here I am on a lockdown Saturday.... Been "asked" by my other (better?) half to paint..... Coming up with more feeble excuses every minute as to why I can't..... All because I have been sat watching this channel continuously for the last 5 hours! 5 hours! Mr Scott, you are a legend and a true joy to listen to (a cross between David Attenborough's soothing voice and Johnny Ball's enthusiasm).
Thank you!
Very well filmed, on par with a TV show/or better than a news segment
I like how Tom referred to a swimming pool as if it were a standard unit of measurement.
*+Tom Scott*
Wow Tom, thanks so much for sharing this. I love this stuff. You keep sharing little bits of what keeps our world running and although this is in the U.K.
it's still relevant to other nations of the commonwealth (New Zealand, in this case), and I just love the engineering of such spaces. My dad (deceased) worked on the Roxburgh Dam here in New Zealand and I have visited a lot of hydro projects here. From a time when governments built such places and we, as taxpayers and citizens, were proud of such achievements. Now corporations make money off the back of such efforts and I dread to think what would happen if they were left to give a maximum shareholder return at the lowest price they deem possible. (sigh)
"In a rainy part of Wales" Joke's on you, Tom, all of it's rainy.
THANK YOU SO MUCH for all the work you have done to educate the masses.
Been there, the whole area is amazing, the mountains, the lakes, the old quarries, there is another one of these just down the road at Bleanau Ffestiniog
Well yes it is Snowdonia and like just down the road from it is actual Mt Snowdon one of the tallest mountains in the UK

Honestly the most impressive part of this place is that someone found a use for wales.
"Electric mountain" sounds like it is the lair of a Scoobie-doo villain! I love it!
Tom himself is a National treasure
A couple years ago we went on holiday in Wales and stayed in Llanberis which is right next to electric mountain. It was a really cool experience in there and the insight came in use when I was studying A level geography.
We used to have a cottage on the other side of this mountain, near Marchlyn Mawr lake.
One time we went for a walk up that way and got kicked out quite quickly by security, I'd imagine the lake can be quite dangerous when the water is being drained.
They do tours through this. I dragged my long suffering partner through it a while back. To me, it's genuinely interesting. Engineering at its finest.
That's a long partner!
@@jahinzee what is a long suffering partner ? is he talking about his pheenis ?

Wait wait wait... the British electricity grid works because of a battery owned and operated by Engie ? But... Engie is the former GDF, aka the French public gas system (that got privatised for some obscure reasons), and it is still partially owned by the French government. So the British grid is owned by the French. After centuries of war and diplomacy, we finally did it, we own England ! Victory at last !
So whenever there is someone on the tv making fun of the French there will be a sudden glitch in the power grid. 😃👍
It's true the French have finally won but the British will always have Agincourt (349 years after that unfortunate event at Hastings).
It is the facility that they own not the grid itself.
Nationalisation is bad except when it's foreign nations apparently.
Well after Britain saved French ass twice in a century, the least France can do is to pay back Britain in the form of the LARGEST BATTERY EVERRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRR
I wish your videos were longer. I bloody love them.
You should have your own TV programme. Very informative, well done.
You are a car drive away from Wirral, you should go there and explain why you hate it so much...
I'm from there and I approve of this message.
Everywhere in GB is a drive away
Fun fact : This was one of the main power stations that kept wales completely on renewable energy for 1 day
It isn't a renewable source though, so that nullifies the claim somewhat.

You saw his helmet? TH-cam is family friendly.
The same principle as between Kochelsee and Walchensee in Bavaria, just that those are natural lakes 200 meters elevation difference and started to operate in 1924. Now imagine excess solar or wind energy to pump the water up.
I remember going here as a kid! We were meant to go up mount snowdon that day but the weather didn't allow it and thank god for that! This place was way more awesome than some mountain!

Apparently when the adverts for soaps are on, the energy levels increase dramatically
Plane geek 118 it does, back in the 80’s and 90’s when as the guy said, there was only 4 odd channels on tv, something like a Christmas episode of eastenders would get insane viewer numbers of like 20 million and so on, and when that ends, 20 million kettles turn on and I remember back in the 90’s a few times that the power would go out (maybe only 10-30 seconds) or you’d see the lights flicker, because a popular show on tv had just finished and half the country was making a cuppa!
I’m sure it still does now too but viewer numbers don’t reach what they used to as there’s so many channels now plus you can record shows etc meaning it’s all spread out more! I’m sure it still peaks during soap advert times but not as intense as it used to be
I remember someone said Britain had a assive power down when all the nation turned on their electric kettles at the same time.
Thats the most brtitish thing i've heard
Rainy bit of Wales, slight tautology there I should think :p
The public tour of this place is well worth the price of admission.
Never knew this existed, how does it compare output wise to Cruachan Power Station? These designs have to be a major part of the solution to our power needs in the future. A dam at height and a generator and pond at the bottom,you could even use excess solar / wind generation to pump the water back to the reservoirs at times of low consumption! They can also be made at various scales depending on the geography
I assume that the rain is bonus energy. Is it significant and is any attempt made to gather it from a wider area?
There is a slight catchment in the above reservoir of Marchlyn Maur, however they don't want to extend that catchment area in case it effects the surrounding environment, keep in mind this is in Snowdonia National Park which has multiple rare species of flora and fauna which rely on the specific climate, which includes the Snowdonia high amount of rainfall, to divert water and deny it for wildlife on the rest of the mountain would be detrimental.

Getting Team Fortress 2 flashbacks
When I was younger and saw signs for this in Wales I thought it was a theme park 🤦
We have a similar facility in Czechia. It's called Dlouhé Stráně. I've been there two times. Once on an excursion and once just on a hike and this place just blew my mind. Such a marvel of modern engineering. Also notable fact is that is's built in the middle of protected landscape area, so most of this aparature is very well hidden underground. The only visible parts are the lake on top of the mountain, the dam down in the valley, an entrance into the underground facility and unconspicuous mountain hut, which is the administration building and powerlines. Even the electric lines are painted green and the isolators are made of clear glass so they don't disturb the landscape as much.
I remember hearing about this place at school. Nice to actually see and hear about it. Thanks!
