Electricity was first introduced to Cambodia in 1906 by Compagnie des Eaux et    Electricité  (CEE), Union d'Electricité d'Indochine (UNEDI) and Compagnie Franco  - Khmer d'Electricité (CFKE). CEE was responsible to supply the electricity to Phnom Penh and suburb, while UNEDI operating throughout country except Battambang  province, which was supplied by CFKE.

In October 1958, Cambodian Government purchased the CEE's and UNEDI's concession rights to form the Electricité du Cambodge (EDC) to generate, transmit and distribute the electricity in Phnom Penh and provinces throughout Cambodia. During the long war, EDC's facilities were destroyed.

In   1979, EDC was re-integrated into an administrative structure under Ministry of   Industry and then transferred to be under management of Phnom Penh Municipality  in 1991, by the name Electricité de Phnom Penh (EDP) to manage the electric supply in Phnom Penh while the electric generations in the provinces were managed by the Department of Industry of the provincial authorities.

In 1992, EDP was re-named Electricité du Cambodge and was attached to the Ministry of Energy. After election in 1993, EDC was restructured under the Ministry of Industry, Mines and Energy (MIME) and was responsible for the development,   management and operation of the power system in Phnom Penh.

Power utilities in the provinces are under the control of Provincial Authorities, which receive budgetary support through MIME.

In March 1996, by the Royal Decree, Electricité du Cambodge became a wholly  state-owned limited liability company to generate, transmit and distribute electric power though-out Cambodia. EDC is a juridical organization with administrative, financial and managerial authority. EDC is responsible for its profit and losses and liable for its debts to the extent of the value of its assets.
