The 20+ most underappreciated/unrecognized power centers (literally) for the prosecution of Russia's war on Ukraine.

These are the workhorses of 🇷🇺🚊logistics & enable the delivery of more death to Ukraine than airbases in Engels or Kursh.

We'll never see 🛰️ images posted. 😤
/2 Each Traction Station has at least two (2) high voltage step down transformers about the size of a Russian tank or MLRS, which go figure can't move or be hidden.

The giant tank full of oil mounted above them guarantees a destructive fire, more certain than oil/fuel tanks.
/3 TBH I deprioritized the southern Luhansk route, given the route via Luhansk (city) is not electric rail & crossings of the Siever Donetsk River are compromised.

However, everything, incl heavy Dragon's Teeth & shells enter via Likhovskoy - Ivanivka route.

These will be added
/4 On the Rostov - Taganrog - Donetsk route, AFU recently #HIMARSTime'd the traction station at Ilovaisk.

Good chances Mandrikine & Krynychna traction stations were torched prior, but I have no confirmation of any🇺🇦🚀💥

IMHO this was a good sign AFU now appreciates their value.
/5 On the southern axis, the rail connection from Kerch is not electrified, however Sebastopol to Melitopol/Novo Bohdanivka is.

We know Orcs use rail heavily to steal🇺🇦grains & Ag equip

There's little indication RuAF is using limited diesel electrics from Dzhankoi to Melitopol.
/6 In the northeast, the value of the Belgorad link is of historical note.

Arguably Valuyki is a "has been" also.

I repeatedly see the non-electrified Valuyki - Starobilsk line pushed as some "darkhorse" 🇷🇺 logistics superweapon bc somebody looked at rail maps.

IMHO it is not.
7/ Then there is the Liski - Rossosh - Millerovo realignment completed in 2016 as a major priority from Putin & The Kremlin to get around previous transits of Ukrainian territory near Chertkovo.

Frankly, I'm tired of beating the AFU Must Absolutely Disable These Assets Drum.
8/ Finally, there's none of my skin in this game. I'm safe in America and this war has no impact on me whatsoever, while I could give 2 f*cks about military warporn.

It's not for me to decide what is💥but it is clear assets I OSINT/identify enable untold misery upon Ukrainians.
9/ These traction stations & electric transformers in 🇷🇺 I beat the drum endlessly, need to be addressed, taken seriously & prioritized above all others in Russia.

I have no reach, so please copy link to the 1st tweet & share 🧵widely with UA influencers.

Only after like 5,000 hours of research & 1,000 russian subs later would this 110kV substation w/ rail traction station make it to my targets list.

To think some mid-level drone operator or 🇺🇦Def Intel ran this up the chain of command to get two 1000km range drones sent at it!😤 Image

🙏 @neonhandrail for verifying "old news"... I can only imagine what "mil sig" UKR attributed to this effort to legitimatize targeting a "civilian" sub.
I've been saying since 2023 UKR hits subs in RF but they are always low value & w/o a coherent strategy
@neonhandrail Time after time, UKR sub & PP strikes in RF get 10s of 1000s of SM engagements... almost always w/o critical assessments of the impacts or context of previous efforts.
We're now at 3rd "winter season" of UKR "teaching russia a lesson", targeting drops to 0, & nothing accomplished

🧵Lots of "highest tier" substation drone activity happening in occupied territories recently versus lower tier tactical targeting of the past.

Has there been a strategic change by AFU recently?

I believe so... scorched earth of grid assets in the OTs is now acceptable.

Unlike OIM - Open Infrastructure Maps, I have always "color coded" based on tiers as seen in the chart above.
What most fail to recognize, OIM uses the same color for 330kv & 500kV (fuchsia), so higher vulnerability network interfaces are easily missed.

What is also lost, the use of 1-phase vs 3-phase transformers at different tiers.

For 3-phase there is 1 XFR, however for 1-phase (read "single phase") there are 3 XFRs.

For 330/110, 220/110 & 110/35kV always one 3-phase XFR.

For 500kV & higher usually three 1-phase XFRs.

From St. Petersburg to Lake Baikal there are no other assets more critical to Russia's Industrial Energy Military Complex than 500kV Large Power Transformers (LPTs) of its industrial electricity network.

We know 🇺🇦 long range One-Way-Attack (OWA) drones torch them, nicely.
1/4 Image
And we know exactly how many there are and exactly where they are located, almost all of which are entirely out in the open.

We know they connect Russia's power stations (nuclear, hydro, gas & coal) to large industrial loads & logistics, requiring 10s to 100s of MW each to operate.

Also, most Russian cities have networks with small power stations to provide civilian needs, but not large loads.

In yesterday’s 🇺🇦drone barrage of Kursk, @kromark suggested 🇷🇺EW near the 110kV substation was the target.

I’ll bite!

EW=RADAR to non-military types

Look at this post from December 2022, when Kursk AFB jet fuel storage tanks were the target for 🇺🇦

16 mo later LPTs are HVTs?
I have no reservations for scorched earth in 🇷🇺out 250km from 🇺🇦, w/ systematic destruction of 🇷🇺grid the backbone to this ‘drone sanctions’ enforced DMZ.

Value of this approach has been dismissed by so called ‘experts’ since day 1, unless it was explicitly military or fuel🎯
It is also dismissed by those claiming russia’s massive strikes on the🇺🇦grid was a ‘failure’ bc 🇷🇺 had no ‘military victories’. Apparently loss of industrial capacity and civilians is not ‘military victory’ enough for the western jarhead?

How big & how much power do LPTs "transform" in large transmission hubs found in Russia?

Enough that you need 3 massive single phase LPTs, plus a redundant set to convert 750kv to 500kV or 500kV to 330kV or 220kV.

You can build to do "3x" through a pair of 3-phase for 220->110.
What is a "phase"? Those are the 3 big bundles of cables you see on transmission towers, each carrying a third of the AC power as it cycles 180 degrees from the others. R/G/W above.

Most 0rc 500/220kV stations have at least 1 additional 1-phase LPT on site, some 2. BLACK wire. Image
What are these?

Reactive Compensation, either 500kV or 750kV.

They don't convert voltages & are used for long distance transmission. They are single phase (RGW) & cost several million dollars each.

They are found in almost all 0rc stations, often equal to number of circuits. Image

🧵What's in Gubkin & consistent with reported 🇺🇦 UAV drone activity that occurred in "Belgorod" on February 6?

The critical, newly built Gubkin 330kv TS (grid hub), opposite the Metallurgicheskaya TS which 🔥
