In 1946, the Department of "Applied Electrical Engineering" was established under the Department of Electrical Engineering at the Faculty of Mechanical and Electrical Engineering of the Higher Technical Institute - Sofia. Prof. Eng. Nancho Stefanov Nanchev became its head.
Two years later, the department was renamed the Department of "Electric Power Plants, Networks and Systems" with Prof. Eng. Nancho Nanchev as its head. In 1964, this department was split into two separate departments: "Electric Networks and Systems" headed by Prof. Eng. Nanchev, and the Department of "Electric Power Plants" headed by Prof. Eng. Koco Avramov Hristov. 
In 1997, by a decision of the Academic Council of TU-Sofia dated 23.09.1997, the departments of "Electric Power Plants" and "Electric Networks and Systems" were merged into the Department of "Electrical Power Engineering" headed by Prof. Dr. Eng. Petko Petrov Notov.

This is one of the fundamental departments of higher electrical engineering education in Bulgaria. The department has officially approved curricula (for the "Bachelor" and "Master" degrees) and study programs for all disciplines taught by the department, as well as lecture notes. The department has a complete set of current educational documentation, as well as an archive of such documentation for the past 20 years (including, diploma and dissertation works, grades for passed exams, and other information).

The department's faculty members are recognized and leading specialists in various fields of electrical power engineering: 

The department's lecturers are also authors of numerous textbooks, reference books, and other materials used by students in electrical engineering at all higher education institutions, as well as by engineers and technicians in the state energy enterprises and by electrical engineers in industry and transport. The lecturers are also authors of methods, software, projects of national significance, and patents in the field of electrical engineering.
