ECG was incorporated in 1963 and became a limited company when shares were first sold in the firm in February 1997. However the company is still owned by the government.
The enactment of the Electricity Corporation Decree, 1967 (NLCD 125) and the repeal of the Electricity Act, established the Electricity Corporation of Ghana (ECG). For the next two decades, ECG was to remain the entity solely responsible for electricity supply and the distribution networks nationwide. In 1987, the corporation’s sphere of operation was limited to the southern parts of Ghana which also had the greater concentration of customers.
