Historical Background

Origins and Early Development

Commissioned in 1949, the Sofia Power Plant was developed during Bulgaria’s rapid industrialization. Its construction supported post-war recovery and the city’s expanding population. The plant began operations in the early 1950s, providing centralized electricity and district heating—transforming urban life and supporting new housing, schools, and industries (Bulgarian Energy Holding).

Expansion and Modernization

The 1960s and 1970s saw significant expansions, increasing capacity and integrating combined heat and power (CHP) technology. The facility evolved to meet rising energy needs and environmental standards, with major upgrades in the late 20th and early 21st centuries. These included advanced boilers, turbines, and emission controls, aligning with EU directives on air quality and sustainability (Sofia Municipality).

The plant’s smokestacks are an iconic feature of Sofia’s skyline. More than just an energy source, the plant has shaped neighborhoods and provided jobs, contributing to Sofia’s urban identity and expertise in energy engineering.
