Russia's infrastructure is generally robust in urban centers but can be strained in remote regions. The electrical grid is one of the world's largest and most reliable, powered largely by abundant natural gas, alongside significant hydroelectric plants (such as the massive dams on Siberian rivers) and nuclear power.
A defining feature of Russian urban infrastructure is the centralized district heating system (TETs). Instead of individual boilers, large central plants distribute hot water and heating directly to nearly all city apartment buildings during the long winters, a legacy of Soviet urban planning.
Internet and cellular connectivity are excellent in populated areas. 4G/LTE coverage is ubiquitous in cities, and fiber-optic broadband is widely available and historically very affordable. Russia maintains a highly developed domestic digital ecosystem, though recent years have seen increased state regulation and blocking of certain global platforms.
