Communist Bulgaria and the Exploitation of Hydropower on the Lower Danube (1957–1989): An Enviro-Technical Approach

On 5 April 1978, in a grandiose official event, Romanian and Bulgarian leaders Nicolae Ceaușescu and Todor Zhivkov laid the first stone of a joint hydropower plant on the Danube, between Turnu Măgurele and Nikopol. Despite proclamations, the project was never completed, and Bulgaria ultimately abandoned it after more than thirty years of negotiations. This article explores the reasons behind Bulgaria’s reluctance to pursue hydropower development on the Danube. Adopting an enviro-technical perspective, it advances two main arguments. First, it shows that Bulgaria’s approach to river management was not a straightforward effort to conquer nature for socialism; rather, riparian planning was contested from the start. Second, it argues that the river’s physical dynamics played a crucial role in shaping Bulgaria’s position. Environmental factors constrained technological ambitions and ultimately led to the definitive abandonment of the project.
