Development of the State Electricity Regulation
The Electricity Ordinance (Cap. 137) and the Electricity Rules,1955 were the earlier regulatory frameworks that regulated the electricity in the State. The Ordinance provided for the appointment of the Chief Electrical Inspector who had the power, functions and duties that largely ensure safety through establishing or adopting standards and prudent practices. For over 40 years there had been no major revision made to The Electricity Rules, 1955 except for minor amendments. But in June 1999, this Electricity Rules was replaced with The Electricity Rules, 1999 which became effective on 1 January 2000. The introduction of this new Rules enhances the requirements for skill and competent persons and registration and licensing of contractors and installations. The Electricity Ordinance was revised and updated to incorporate all the amendments made over the years and became known as the Electricity Ordinance, Chapter 50 - (Revised 2003).

The inspectorate functions and duties of the Director of Electricity Supply were performed by the Electrical Branch of Public Works Department (Sarawak). In September 1994, these functions and duties were transferred to the Ministry of Finance and Public Utilities and continued to be performed by the Chief Electrical Inspector. To strengthen the implementation and enforcement of the provision in the Ordinance and the Electricity Rules, 1999, a new unit known as the Electrical Inspectorate Unit was established in June 1999 under the Ministry. On 1 July 2004, the Ministry of Public Utilities Sarawak was established with the Electrical Inspectorate Unit now comes under its jurisdiction.

With the introduction of the Electricity (State Grid Code) Rules, 2003, which came into effect on 1 January 2004, the role of regulating the electricity supply industry in the State is vested with the Electrical Inspectorate Unit. The Chief Electrical Inspector is re-designated as the Director of Electricity Supply.
