## 🎯 Key Points

- Concrete blocks for anti-drone nets have begun to be installed around Moscow's TETs-8 on Volgogradsky Prospekt
- The reinforcement began after the massive drone attack in the night of September 20
- Sobyanin claimed 450 drones were shot down, but some devices hit the Moscow Refinery, the Sofyino warehouse, and the TETs in Dzerzhinsky
- Moscow residents were not warned by sirens or SMS; ISW links this to the State Duma elections

On Volgogradsky Prospekt in Moscow, where the Moscow TETs-8 power plant is located, urgent reinforcement work has been recorded: concrete blocks are being installed around the power station. This is reported by RBC-Ukraine, citing the Astra Telegram channel, which published footage of the structures being assembled. According to social media reports, the installed blocks are intended to serve as the foundation for the subsequent construction of anti-drone nets around this critical energy facility.

### Reinforcement of TETs-8 on Volgogradsky Prospekt

The work on installing concrete structures around TETs-8 reportedly began immediately after the massive drone strike on the Russian capital in the night of September 20. The choice of target is not accidental: thermal power plants are part of the critical energy infrastructure, and their failure can disrupt supply to entire districts of the city. The installation of protective blocks and the preparation for setting up anti-drone nets indicate that Russian authorities regard such facilities as priority targets for the enemy and are striving to create multi-layered protection on the ground.

### Record Drone Attack in the Night of September 20

Moscow Mayor Sergey Sobyanin called the strike in the night of September 20 the largest attack on the capital and claimed that 450 drones were shot down on approach to the city. Nevertheless, despite local authorities' statements about the successful operation of air defense, some of the drones reached their targets: Gazprom Neft-Moscow Refinery in the Kapotnya district, a warehouse complex in the settlement of Sofyino, and a power plant in Dzerzhinsky were hit. Ukraine confirmed the strike on the Moscow Refinery — one of the largest in the country — where a fire broke out on its territory. President Volodymyr Zelenskyy stated that the operation used FP-1, RZ-100, MICH-2000, Palyanitsia, Vendetta, Lyutyi, Bars, Flamingo, Sich, and Pelican drones.

### Contradictory Data

The versions of the two sides following the attack differ significantly. Russian authorities insist on the high effectiveness of air defense and emphasize that the overwhelming majority of the devices were shot down, while acknowledging only individual "fragments" and local fires. The Ukrainian side, by contrast, records direct hits on the refinery, the warehouse complex, and the power plant, and confirms the destruction of key facilities. Thus, the assessment of the "success" of the interception and the actual damage to the infrastructure do not match in the statements of Moscow and Kyiv, and the exact number of drones shot down and those that broke through remains a matter of dispute.

### Lack of Warnings and Analyst Assessments

Particular attention should be paid to the fact that during the record attack on September 20, Russian authorities did not warn residents of the danger, neither by sirens nor by SMS notifications. According to ISW analysts, the reason may have been the authorities' reluctance to reduce turnout for the State Duma "elections," which were held during the same period. The combination of these factors — the record scale of the strike, the confirmed hits on energy and oil refining infrastructure, and the urgent concreting of TETs-8 — indicates that the protection of critical Moscow facilities is becoming one of the priorities amid ongoing drone attacks.
