Lembaga Letrik Pusat (1949-1965)
The Lembaga Letrik Pusat (Central Electricity Board, CEB) was established and came into operation on 1 September 1949. The Board was to become heir to three major projects considered by the Electricity Department following its re-establishment in April 1946 which were the Connaught Bridge Power Station, Cameron Highlands Hydroelectric Project & the development of a National Grid. CEB eventually became the owner of 34 power stations with a generation capacity of 39.88 MW, including a steam power station in Bangsar with a capacity of 26.5 MW, a hydroelectric power station at Ulu Langat with a capacity of 2.28 MW as well as various diesel powered generators with a total capacity of 11.1 MW.
Lembaga Letrik Negara (1965-1990)
On 22 June 1965, Central Electricity Board (CEB) of the Federation of Malaya was renamed as the Lembaga Letrik Negara (National Electricity Board, NEB) of the States of Malaya. By the 80s, the Board was supplying the whole peninsula with electricity, strategically replacing the Perak River Hydro Electric Power company (PRHEP) and its subsidiary Kinta Electrical Distribution Co. Ltd (KED) in 1982, Penang Municipality in 1976, and areas supplied by Huttenbach Ltd in 1964, which included Alor Setar, Sungai Petani, Kulim, Lunas, Padang Serai, Telok Anson, Langkap, Tampin and Kuala Pilah.
On 4 May 1988, Prime Minister Mahathir Mohamad announced the government’s decision on a policy of privatisation. Two pieces of legislation were passed to replace the existing Electricity Act and to provide for the establishment of a new corporation. Tenaga Nasional Berhad (TNB) was formed in 1990 by the Electricity Supply Successor Company Act 1990, to succeed the National Electricity Board (NEB) of the States of Malaya.
