It's not a jet engine. This is a Frame 5 GE Heavy duty single shaft gas turbine generator that runs at 5100 RPM and through a gearbox turns a generator at 3600 rpm. I installed and serviced GE Frame 3's, Frame 5's, Frame 6 and Frame 7 gas turbine generator drives. I can't tell from the outside but my guess is that this is a simple cycle Load Peaking version of Frame 5 unit that puts out 24 Megawatts. The diesel engine starting units I saw all had Detroit 12V-71 twin turbo 600hp engines. Are you sure its a 12V-92? Some very old ones used 350hp Cummins V-8 engines. I have had tons of these units apart and have casings 3-6 inches thick, the turbine and generator rotors each weigh several tons, and there are no aircraft parts in them at all as compared to a ''light weight'' aero derivative GE LM2500 which was based on a DC-10 jet engine. This particular gas turbine can be remotely started. It has black start capability with the diesel and can be readied to be put online with no external grid power available. Some are electric motor started and some have steam turbine start. What you hear at the end of the video is pretty much like it sounds at full load. There is no thunder! That exhaust stack at 1:30 has turned blue because of massive amounts of hot air at 1000 degrees F coming out of a 13x13 foot stack. The diesel is inside the accessory cab which has the 5 black radiator inlets toward the right, and the round fan housing on top. The turbine air inlet is the stack with the snow on top. The generator cab is on the far left. The Accessory, Turbine, and Generator and Control cabs were designed to fit through railroad tunnels throughout the world. They are easily set on a massive concrete foundation where they are bolted down, piped, then aligned, and all of the external pieces are added. It takes about 3-6months to put one together. Fun fact...it has 2 spark plugs. They retract from the combustion liners as the compressor discharge pressure builds up. I blacked out the entire East side of Lake Maracaibo in Venezuela long ago when one unit was down for maintenance and the other was at full load. I was behind the Speedtronic control panel and closed a panel when a sharp edge shorted out a wire and tripped the unit off line. The Hotel at Mene Grande was pissed off at me. Thanks for the memories. I hope you don't mind a few corrections!

Imagine it’s perfectly quiet and you mistakenly camped nearby thinking it was gonna be a relaxing weekend

12 cylinder pony motor, WOW!

Detroit Diesel two strokes are not just noise generators but supremely reliable and dependable engines. My favourite engine of all time.

Noise generator starting a jet generator. Epic!!

I like reading the comments telling stories about professionals past experiences with these. I'm a year out of welding school and hoping to have memories like these one day.

It's a very cool experience to be in the control room hearing that Detroit scream then the shrill turbine sound.

You KNOW somebody is out there right now thinking, "How can fit this under my hood?" Thanks for the vid, the sound of sheer power!

I came for the video, but stayed for the comments! Wow!

Got to love those Detroit diesel engines

WOW! The 12 cylinder Detroit is a pretty strong generator itself.

Love these sorts of videos. Big Detroit Diesel and turbine engines, enough output to power a medium sized town. Love the hidden infrastructure that maintain our world.

We have a Pratt & Whitney Jet (and it's an actual JET engine) with a similar output. It has an air start supplied from a 450psi reservoir. From the time I push the button, it will be synched and on-line in 8-9 minutes and will autoload to up to 24 MW's depending on the ambient temperature. We use water injection for NOx control. There used to be two of these P&W jets at my plant, but one was removed in 2004 and not returned due to permitting issues (we're in the middle of a big city). For 40+ years they ran on Jet "A" but were converted to run on No. 2 ultra low sulfur distillate a few years back. The jet gives us black start capability. The plant's prime mover is a GE 7F gas turbine which powers a 175 MW (nominal) generator. This runs on either natural gas or the same No. 2 oil as the Jet. We're permitted to run the big machine on liquid fuel up to 720 hours a year. The exhaust from the CT is used to make steam in a HRSG which in turn runs a 1300-200psi Back Pressure Steam turbine which supplies steam to a large district heating system.

I maintained 12v149 Detroit’s as ships generators for years. Slept many nights above three of those quad turbo/twin blower monsters...

*Fun Fact* This is where all the EVs actually get their power. *Edit (Thanks for the upvotes for this silly thread. ) Now, dance my pretties, dance! 😋

When I was going through automotive trade school in N.E. Ohio during the late eighties. I worked at an industrial radiator repair business. We re-cored those massive industrial radiators used in these supplemental generators. The radiators alone can weigh several tons. That's when I learned about waterless coolant. It's awesome stuff. It doesn't expand when it gets hot like traditional antifreeze, meaning you don't need a high pressure cooling system to keep the water, like in traditional water mixed automotive antifreeze, from gassing (boiling) because there isn't any water in it. When you don't have to also make the radiator a pressure vessel, it significantly decreases unit cost and increases the units life. I now put 'Evan's' brand waterless coolant and a 3 psi radiator cap in all of my vehicles and I haven't had a cooling system problem since. When radiators and heater cores are constantly being expanded under pressure, they eventually fail. Especially modern automotive radiators with 'plastic' tanks. It's awesome stuff. It was made for industrial applications but now, You can just buy it right on Amazon. I heard about Evan's 9-10 years ago finally being available to consumers and I've been using Evan's Waterless Coolant ever since. I swear by the stuff.

Very cool, some serious power! Now now you got tree huggers all upset, but least they are warm 🤣

We used to have a Pratt and Whitney Twin PAC 40 MWe at our power plant. It could remotely start a go to full load in three minutes. We almost always locally manually started it for summer peak loads. Overspeed testing was really cool!

Ahh Lost Nation CT, I always was curious how it sounded when starting, glad to know it’s finally fixed. It’ll get a work out this winter for sure. Thanks for the videos.

Absolutely love the sound of a 2 stroke Detroit Diesel going flat out, especially a 12.

Our local utility has two 50MW (I believe) units about a quarter mile away from our small power plant (University). One day they were doing maintenance and had a gas leak which blew out all of the walls of the building. It didn't kill anyone thankfully, but the pressure wave was so large it went around or over our 30,000 ton coal pile and into our turbine room, then slammed into our control room door like someone kicking it as hard as they could.

I love hearing these stories! Union millwright here. Worked on some big shit but not that big super dope!

Love the sounds. Amazingly beautiful

Now that’s an impressive setup in many ways. Love the sounds and whole concept too. Would love to see inside the building as well!

This reminded me of the generators we had in the USAF in the mid 70's. I was in the 3rd MOB (renamed Combat Comm Group). We went out and set up the communication for remote air bases. For power we had 2 types of generators, diesel and turbine. I seem to remember 10KW but not sure. I know we had a bunch of them when we deployed and we towed them behind our trucks. The turbines sounded a lot like a jet starting and they were quieter than the diesels. Helped me to sleep during the day because the constant sound. They did't sound thing like this but this is a whole lot more power!

Back in the 80's ,I worked at Detroit Diesel Research Lab in Detroit. I worked on 53, 71, Silver 92 , 60 and 149 series. The 149 was my favorite of them all.

Thats someone who really knows what they are talking about im impressed🥃

I live right next to that thing. My noise cancelling headphones are just the bomb.

"how dare you" lol👍

Great video and fantastic knowledge from other commenters ! Thanks for sharing.

bro that detroits just loving it

Wow, a buzzing dozen just for a starter! Incredible

When I worked inside the NORAD Cheyenne Mountain Complex, we had 6 Six Cooper Enterprise R3 diesel gensets that generated 10.5 mw to power the complex in an emergency. The noise in a confined space is horrendous, thank goodness for ear protection and soundproof control rooms.

Very cool, and here I thought the two, twin turbo 399 Cat gensets I maintained on on floating fish processor were big! Combined they put out a little less then 2 megawatts, not even close to that bad dad you shared. Thanks for sharing :)

The generator thinking: A'right, guess I'll just follow along then 🤭

Pretty cool... back in the 90s I was in Bakersfield (racing) and a friend headed a crew that just finished rebuilding one of these at an oil field.. it was in "test" run also.. said they had to make sure no vibrations etc... was pretty amazing just how big that thing is walking one end to the other.. I remember feeling it running through the ground..

That's incredible. I love this. I'm an industrial generator technician and have never seen anything like this, especially in FL, where standby power generation is so important.

That 2-stroke V12 sound though! That thing sounds crazy for a diesel, as if it revs at 7000 RPM. It doesn't of course, but it sure sounds that way.

Deep in the primeval forest, kingdom of nature's repose and silence, sanctuary from the cacophony of modern life, is this shrieking ear-shattering banshee. How cool.

Superb episode, thanks. Cast off all lines fore and aft! Ah…so windmills and solar panels are supposed to replace diesel fuel, coal & nuclear energy power generation? Maybe in 200 years from now. Carry on!

At Rolls Royce we used build stations like this, after the ice storm in 98 Royce’s installed a test Bed near Montreal so they could run turbines to generate power for hospitals in emergency situations

That high pitched scream is what my tinitus sounds like just not NEARLY as loud.

We have 5 of those in a back up power plant in the city of Vega Baja, Puerto Rico. They are used as back up when one of the main power plants on the island goes offline. They had to build a sound dampening wall around the complex due to neighboring communities complaints about the loud sound.

That's a big one. where I work we have a bunch of Kawasaki turbine generators that run off of natural gas, they use compressed air starting and can be brought up to full power in 1.5 seconds, and they're quieter than the diesel gens, which is saying a lot since our diesels are pretty quiet with the massive mufflers and sound deadening enclosures, and these are huge 20 cylinder diesels identical to what you'd find in a locomotive.

Right around the corner from my house. This thing is insane, can hear it for about a mile.

Love the 2 cycles!! Still a great engine!!

I work on industrial generators and never knew anything like this existed. Fricken amazing

That’s what is required on the grid when the renewables don’t generate.

Getting ready to charge all the e.v's. lol

That sounds just like the vacuum cleaner I returned to Amazon last month. On Monday it sang like a bird on Tuesday it nearly ruptured my eardrums!

I remember in the Chicago suburbs I grew up in had some of these just off a bike trail in a large switching area. Would hear them going full blast during peak summer demand.

the buzzin dozen does it again

Interesting video. Here in the UK we used to have big 2000MW coal fired power stations with industrial versions of the Olympus jet engines fitted to them that were used on Concorde and Vulcan bombers. These generated 32 MW to get the coal conveyors, coal mills and pumps and fans running in the event of a black start situation. I don't know if they used a diesel to get them going though.

Bet the wildlife love it! Warms up the immediate area, too!

These are my two favorite mechanical sounds 👌

A 12 cil Detroit as a starter motor. That alone makes it amazing.

I want that diesel, "for my square body pick-up". (thumbs up)

Wow, look at them nice blue stains on that stack--HOT STUFF COMIN' THROUGH! Nice vid, pardner.

They're waiting for you Gordon. In the tesssst chamberrrrr.

it takes a while for that Detroit to spin that turbine up. it's gotta get to like 80% of it's operating RPM before it can light or it'll burn to death, and getting there is taking all that detroit has to offer lmao. I bet the clutch in that gearbox is MASSIVE

That sound made me think the only way anyone standing in there is either deaf or with shooting range quality ear muffs.

Some dodge boy will say it needs a Cummins swap.

I love the lack of context in the description, it really makes this video make sense.

Any 12-cylinder Detroit sounds amazing at full welly. The hospital where I used to work had three emergency generator sets to supply all its power if Edison was offline, and each set had a quad-turbo Detroit 12V149 that was kept warm and ready to go. When all three were running, their noise during the Wednesday morning weekly tests was amazing: my bus's puny little 6V92TAC tries so hard to sound like them, but it just can't compete! I hope the video's Detroit starter engine was idled for sufficient time to cool down its turbos after it was disconnected from the gas turbine.

The start cart for the SR-71 Blackbird had two Buick 400 hp engines coupled together to start the J-58 engines. One start cart for each engine. People say it was like the start of the Indy 500 since the Buicks had straight pipe off of each cylinder.

The funny part is I used to start a 12V92 once a week that powered a 1 Megawatt generator we used for standby power. This installation in the video would give around 15 Megawatt. And as far as not a jet engine, Tomato Tomato. Any "jet engine" is a gas turbine.

Very cool!! Great black start capability there!

That's one big pony motor!

Engineer: we don't need mufflers it's only a starter engine Company: Well done for saving us money Engineer: Guys, listen to this

Thank goodness for environmental noise regulations and the acoustical consultants who design noise control for these necessary units.

I worked in Prudhoe Bay in the warehouse delivering parts all over the ARCO side (BP had the other side), all three Flow Stations had GE LM1500 turbines compressing the gas being separated from the oil before being sent to the Gas Injection Plant for compression up to 3000 psi to be injected back into the dome. Each Flow Station had a Frame 5 generating electricity for the Station, they are huge. We had several LM1500's in the warehouse in their cans ready to go out if necessary. The scale of everything up there is staggering.

You should see the size of the detroit diesels on top of the Calgary alberta General Hospital, Huge. Saw them when went to Detroit school in calgary years ago in the 80s.

Reminds me of the old way SR-71 engine was started. Except it use twin Buick Hotrod engine 😅

Aw yiss! This makes me headbang. This is METAL!

A few years ago I was brought in to decommission a gas turbine set at the old Emery Air Freight headquarters in Wilton Ct. As I recall it was direct coupled via a gearbox that took the 18,000 RPM down to 1,800 RPM for the gen end. It was oil cooled and electric start. This was a standby set for power outages and was installed circa 1970. What they used to keep the building powered while this spooled up was a giant flywheel system that was out in the parking lot. That was basically a mechanical UPS for the mainframe computers in the complex. I have some detailed pictures around here someplace. BTW, the flywheel system was pulled out around 25 years ago so the turbine was collecting dust and talking up space. The new tenant had a better use for all of those square feet.

Where is this? Alaska? BC? Almost reminds me of the story of how they started up the SR71 Jet engines with Buick small block and Chevy 454 V8s

I work in telco at a network switch building. We have a pair of 1.25MW V-16 Cummins diesels for backup power and I thought _these_ were massive. Never seen or heard an actual power plant generator before!

I used to heard a Euc/Terex R-35 rigid frame haul truck and a TS-24 pan and both had 12V-71 motors with Allison trannys and they were STRONG! And as far as a turbine burning 2K gallons an hour, after they fire, think about it. It's a steady stream at full load. It wouldn't take long.

I have feeling that this is the noise people are hearing when you watch those spooky noise videos and they are like 20 miles away and they are recording in the woods.

Is it really a aviation based gas turbine? GE built some monsters that would definitely need all that torque to get going but the Apu's in aircraft and fart carts are tiny when they're just used for starting (rather than having to supply hotel to 200 passenger) Awesome video, did it stink of raw fuel hanging in the air?

Wow a Motown Stroker spinning up a gas turbine , very like the Bristol Siddeley Olympus Genny sets used in UK Gas Turbine Power Stations. Love the scream of that GE Turbine spinning up to full load, though most gas turbines are started on compressed air.

Glad I don’t live close to that 😮

Yes, but what starts the engine that starts the jet?

Generally, the turbines are started with compressed air from a compressor driven by the diesel engine. This can also be accomplished with stored compressed air. Cylinders with high pressure compressed air (3000 psi). The air is reduced to a low pressure, high volume flow of air to spin the turbine.

We have one of these 12V92’s at the health care facility, (I work engineering and maintenance) as the emergency diesel generator. It’s 33 years old and runs like a clock. That isn’t stopping the stupid health system from wanting to replace it. Dumbasses! It is a wonderful machine.

Virtue signalers who plug in their EV's into this grid, seem to forget about this part, lol....

It’s a gas turbine, not a jet. There’s no fan generating forward thrust. It’s either shaft coupled to an alternator or gas coupled to a power turbine that drives an alternator.

That must be loads of fun to live near. LOL

To all the assholes after the Hurricanes complaining about the generators. I want to show them this video and say it could be so much worse. To be honest with you after the first five or six hours I don't even hear the damn things anymore. Even the neighbors genny running doesn't bother me because I know we need to have them. This Beast, I could not ignore no matter how hard I try.

I can't believe they're running this thing without a muffler lol. I want this in Greta's neighborhood.

Try generating that kind of power that fast on demand with wind or solar 😂. Drill baby drill and keep that crude pumping.

Good thing they have these, wouldn't want thier electric cars to run out of juice

Hell, you KNOW it's a bigass motor when you have a 12V92 as a pony motor starter!

FJB will have that shut down soon.

When the wind doesn't blow and the sun is blocked by clouds, start this reliable energy soarce so houses and people won't freeze. An energy device made to work under any conditions. We need more of these instead of expensive unreliable green garb because of the coming ice age in a thousand years.

I worked for a company in Arkansas that built air filtering units for these. The town over install a couple to cut the peak on their electric usage.

I worked at Siemens Westinghouse for 21 years. Aircraft converted power plants are cool, but not as efficient as dual cycle stationary industrial turbines. Those are built for torque, not thrust. Ours weighed in the order of 300 tons.

Just put in some solar panels lol

I remember the days that motor was running up and down the highways in long nose Pete's, KW's and an occasional Autocar. Based on and with Allison these motors were found in the PT boat's and P51 Mustang's. Backed with a 5X4 two sticker, 3:53 and tall rubber these would blow flames out the stacks.
