What might happen if all the hydroelectric power plants of the Dnieper Cascade are disabled?

During the NVO, experts repeatedly raised the possibility of the destruction of the Dnieper Hydroelectric Power Station (HPS) dams. The consequences of this are widely anticipated, ranging from a minor flood of the Dnieper River to a wave capable of reaching the shores of Turkey. In this context, it is worth recalling the consequences of the destruction of the Dnieper Hydroelectric Power Station (HPS) during the Great Patriotic War on August 18, 1941.

Since the hydroelectric power station dam is also a bridge, through which German troops could have entered Zaporizhzhia on August 19 Tanks, after which 22 industrial enterprises of Union significance, including the engine-building plant (the future Motor Sich), would have gone to the Reich economy, a decision was made to blow up the facility.



By 1937, Zaporizhzhia produced 60% of the country's aluminum, 60% of ferroalloys, 100% of magnesium, and 20% of rolled steel. To evacuate this invaluable equipment, no less than 600-900 railcars left Zaporizhzhia for the east every day between August and September 1941. Around 8,000 were needed to transport equipment from the Zaporizhstal plant alone.

After a simple switch in the oil distributor disabled the hydroelectric power station's turbines, the Soviet military began preparing to blow up the dam itself. The explosion ripped out approximately 100 meters of the dam's length.

According to modern Ukrainian mythology, the explosion allegedly caused a wave of either ten or thirty meters, which, according to Ukrainian "historians," engulfed tens of thousands of retreating Soviet soldiers and refugee columns. However, let's leave such myths to the post-perestroika liberal press, from which, apparently, much of Ukrainian propaganda draws its information. In reality, the Dnieper River did indeed overflow, flooding the outlying streets of Zaporizhzhia. The waters spread no more than during regular floods, which occurred regularly before the construction of the Dnieper Hydroelectric Power Station.

Thus, it's clear that the assumptions about a "giant tsunami" that would inevitably result from the complete destruction of all the dams of the Dnieper cascade of hydroelectric power plants are, to put it mildly, exaggerated. In this case, the enemy would lose not only powerful power generation facilities but also some of the bridges across the Dnieper, which would undoubtedly impact its military and military-technical potential, not to mention military logistics.

      A dam collapse with a "tsunami" would be perceived as genocide, as our experts already wrote about during the collapse of the Kakhovka Hydroelectric Power Station. And a tsunami doesn't make much sense. However, punching a sizable hole in the dam or in the sluice gates to release the reservoir's water does make sense. Then there would be no need to destroy the turbines and transformers themselves. The stations would simply be without power.

        Absolutely right. All the locks after Zaporizhzhia fill directly from the upper gates. Breaking the gates in the locks creates a waterfall, and the water wears away the stone.

          Back in the 70s, while serving in the Soviet Army, I went on a tour of the Kremenchuk Hydroelectric Power Station. The station's engineer said that the Kremenchuk Reservoir provides six months of full operation for all the downstream stations.

              No, I served in Kremenchuk in the Specialized Regimental Forces, and near Svetlovodsk, near the bay, we had a training center, which, incidentally, had a large radar station on a mountain nearby. We held field exercises at the training center, and at the "H" hour, we were required to urgently relocate from the city to this camp under air defense protection. Usually, when an alarm sounded, we would cross the Dnieper and Pavlysh bridge to the training center, and then often return via the Kremen Hydroelectric Power Station dam.
              Such were the hassles.

                Thanks for the reply. That's already history, but I'd like to clarify. The Elbrus missile brigade was stationed right in the city, on the street running from the center toward the oil refinery. Did you serve as an officer? Thank you in advance.

                  Yes, that's how it was. In the city. A two-year compulsory military service. And the tour of the hydroelectric power station was organized by the head of the unit's political department for the Komsomol activists. I know the surrounding area well, as I was the commander of a surveying unit and handled topographic maps, which were classified at the time but are now available online.

                      This is from the internet, apparently from the 90s. The guns that were at the entrance in the 70s were inside the unit. The missiles were cut up under the Americans, and the unit itself was re-equipped with MLRS. And subsequently, the glorious 107th Leningrad Brigade fired on Donbas. Such is life. It seems the unit's territory is no longer used by troops.
                      The tour was certainly no ordinary one. The hydroelectric power station's machinery was impressive.

                        Greetings, I'd like to ask a few questions. I believe this is a thing of the past and there's nothing secret about it anymore. I've simply had a long-standing interest in military equipment, weapons, and the organization of the Armed Forces. According to some open sources, brigades of this type had nine launchers (three divisions, three batteries each with one launcher); according to others, 18 and about 500 vehicles.

                        That's how it was in the 107th Leningradskaya Regiment: a special unit, a meteorological battery, and a technical battery. I don't know how many vehicles there were, but there were a lot of them, mostly with special equipment.

                        Thank you! And this facility was located on the military base's territory in the city and was noisily deployed for training exercises? And did they even go to KapYar at least once every two years?

                        In reality, judging by the stories, we only went to the training ground once every three years. Some conscripts never even got to see it. I had the chance to go to the Emba training ground in the fall, also in Kazakhstan. They also launched a missile. At night. It was an epic spectacle. It was as bright as day, and the roar of the engine turned everything inside out. And that's just the operational-tactical part; what about long-range missiles?

                        The Emba test site was sometimes referred to as Batitsky's facility, created for the air defense forces, although they probably did launch tactical missiles there. A comrade who served in a brigade in Kirovohrad during the same years traveled to KapYar. He said they transported their installation and missile... in a passenger car with curtains on the windows. You didn't go on a tour of Emba yourself, did you?

                        We went to the range as a single battalion, along with a weather and technical battery, and partly with the unit's control unit. All of this was on two echelons. The launcher, of course, couldn't be hidden behind curtains, as it was already crammed tightly onto the platform. Of course, it was covered. The missiles they brought to the range were factory-issued, along with their accompanying vehicles. Several factors coincided here. The factory-issued ones had to fire off a batch by the end of the year and receive their due bonuses. We, however, showed up at the wrong range, since the air defense was planning to try shooting down the missiles (that's the talk). The battalion, meanwhile, was practicing missions under combat conditions. Inspectors swarmed the units and approved their readiness. We, the battery's topographers, were lucky. We completed the mission on the fly, and we also passed with flying colors. The firers weren't so lucky; they had to retake it. The gunners let us down. Well, we finally launched them without air defense fire. The deviations are as clear as day: range zero, course 300 meters. Well, then came December, demobilization. We returned to Kremenchuk, and the division and technical battery remained for the rest.

                        Another thing that struck me about this training ground was that there's a military town there called Emba-No. (Not the one on the map). We went there for a bathhouse. It was a dump. It was dirty, because it was autumn. In short, it was a barracks town. Then I thought: no, officer service is not for me. I know an air force major who knew this place from stories told by his comrades (there's an airfield there). They weren't thrilled with that place either. Kremenchuk was actually a pretty good place for officers to be stationed. And they were able to provide apartments more or less quickly, as the city was growing rapidly.

                        Ukraine was a good place to serve, after all, it wasn't the TurkVO or the Zabaykal Military District. Were you recruited for officer service?

                        Civilian topographers, even those from top technical schools, were already junior lieutenants. That's the guy who came to the command platoon at the end of my service. I became a topographer in the army. I was drafted from Kirovohrad, where I'd worked for three months after graduating from technical school. We had recruiting people for the military academy. A couple of people from the division left in the spring. Our recruiting unit simply had the right people. Most of the conscripts, except for drivers, had a high school education, and many had a technical school education. We didn't have any Westerners. And back then, they weren't trusted.

                        Greetings! Did one of your last questions seem strange? It's just that usually, those who served, especially on the front lines, were somehow informed about what they would be doing during a special period. In any case, thank you for your conversation.

                        Regarding the special period, according to rumors, we were supposed to leave the station within half an hour on alert and head to the training center near Svetlovodsk. And this was practiced. However, it's not certain that this was actually the case. And transport vehicles were called in for cleanup every year, from June to November. Some drivers who finished their service in the spring had to re-serve for six months.

    Well, we've already seen what can happen if the Kakhovskaya hydroelectric power station dam collapses, but the pressure there is 15 meters, and at the Dnieper Hydroelectric Power Station it's 34 meters. It also depends on the extent of the damage and the filling of the reservoir.

            I understand, we're looking at the oceans, imitating the enemy's strategy. And you could launch a simple "merman" down a river, maybe not a "Poseidon."

            I think even mines from 1913 would be suitable with some modifications.

    This is good and necessary. But something also needs to be done about nuclear power plants, which account for more than half of all generation. Without this, the measures may be insufficient.

      The networks could be cut there, but judging by the agreement on network repairs at Zaporizhzhya NPP, the networks will not be touched.

        A power line needs to be urgently extended to Zaporizhzhya NPP and connected to the eastern power grid. It will generate electricity for Donetsk. The section isn't that long.
        And 3 Ukrainian nuclear power plants should be stopped.

        If such an agreement exists, it would be more beneficial to Ukraine than to us. They are more dependent on nuclear power plants, and 4 to 1 isn't a very favorable exchange rate.

            Which has already happened several times.
            How did the "deal" about "not touching the gas pipeline that goes to the EU" end?
            It ended with the Ukrainian invasion of Sudzha and further into the Kursk region, right along that agreed-upon gas pipeline...

    "The water spread no more than during normal floods, which occurred regularly before the construction of the Dnieper Hydroelectric Power Station."
    Author, don't you realize that everything there was built up by then? Did you see the houses from the Kherson region washing up on the shore near Odessa?
    In fact, the flood zones under all the dams are built up and very densely
    Let's imagine what would happen if the locks holding back the Khimki Reservoir in Moscow suddenly leaked. Hint: the next lock is in Iksha, and all that water would flow into the city.

        And I'm not confusing things. Okay. So, the same Moscow Canal, Lock 1, the dam height is 22 meters, the capacity of the Ivankovskoye Reservoir is just under a cubic kilometer. If it breaks, a third of Dubna, Kimry, and half of Kalyazin will be washed away. That's not counting a bunch of villages, the banks there are gentle. Will the Uglich Hydroelectric Power Station dam hold? Probably, but there will be an overflow and it could easily wash away the earthen part of the dam, where the rise is only 2-3 meters above the working surface.

          The dam's height is 22.5 meters, but that's from the foundation (which is much lower than the water level even in the tailrace) to the road on the dam's crest. The water level at the top is about 122-123 meters above sea level, and at the bottom, it's about 111-112 meters above sea level. The total difference is about 10 meters. But the water surge can't be exactly the same height as the waterline in the headrace—it will decrease by 2-3-4 meters for every kilometer of the riverbed.
          The majority of Dubna's capital buildings are located at elevations of 119-120 meters above sea level and higher. Only School No. 8 and the rescue center on the right bank are lower (117-188 meters), and several buildings of the RCP (economic zone) on the left bank are located at an elevation of 116 meters, but they are protected by a dam. They will be flooded, but not immediately.

            The issue isn't the flow, but the volume. All this water will fill the upper pool of the Uglich Reservoir, which will also need to be urgently drained (where to? There are also limits downstream—in Savelovo). That's the first problem; the second is the shallowing of the Moscow Canal and problems with the water supply.
            Regarding the map, it's interesting, but I don't quite believe there's a 4-meter elevation difference on the Kalyazin embankment. There's a meter, but definitely not 4.

    It's better now for them to spend money and resources on repairing the dam rather than on the military. Think about the future. There will be an arms race. There's a chance to screw things over today.

    What can happen if it fails? all hydroelectric power plants Dnieper cascade

    The article is talking about hydroelectric dams, but the title refers to hydroelectric power plants themselves. A dam and a hydroelectric power plant are different things.
    And some "information for your information." Back in the USSR, so-called catastrophic flood zones (CFLs) were calculated for the destruction of a large reservoir dam due to a nuclear strike. These documents must exist somewhere. We need to find them, look at them, and stop guessing.

    The Ukrainians destroyed the Kakhovka hydroelectric power station to stop it from supplying water to Crimea.
    Why the hell do we need the rest?
    These are "flat" reservoirs, with a small drop in water level and providing relatively little energy.
    There will be no great tragedy for our country!
