EDM as a State-Owned Company was set up in 1977, two year following the Independence of Mozambique. The objective was to establish and operate public service in Generation, Transmission and Distribution of electricity.

One of its first tasks was to merge all generation centres into one single body in order to fully meet all electricity requirements for the development of agriculture, industry and household consumption in the long gone hard days.

EDM inherited an asset made up of multi-sourced equipment, various models and types in bad shape of repair, and save rare exceptions, with no stock for the required spare parts, coupled with limited competencies and professional capacity.  Thus, the few existing qualified professionals started leaving the Company.
