Infrastructure - Utilities
Electricity
Both renewable and non-renewable energy sources are utilised for power usage in Malaysia. Non-renewable energy resources include petroleum, natural gas and coal, while renewable sources include hydro power, solar power and biomass power. Energy consumption in Malaysia is sustainable with the current rate of economic development. Approximately 68.34 billion kWh of electricity is generated annually, with 63.48 billion kWh of electricity consumed per year.
Tenaga Nasional Bhd (TNB) is the national electricity utility company, a corporate entity established in 1990. It holds a monopoly on electricity generation, transmission and distribution in Peninsular Malaysia. The same functions are performed in Sabah by the Sabah Electricity Board and in Sarawak by the Sarawak Electricity Supply Corporation.
TNB currently services about four million customers, including industrial, commercial, mining and domestic clients. Different tariff rates are imposed on different categories of clients.
Water
Water utilities in Malaysia are managed and overseen by individual state water authorities, including State Public Works Departments, State Water Supply Departments and State Water Boards. The state water authorities are in charge of regulating water supply, maintaining general waterways and water flow, and pipeline and drainage maintenance.
The central Federal Public Works Department (which comes under the Works Ministry) in Kuala Lumpur oversees the operations of the individual state water authorities. Water supply in Malaysia consists of 97% surface water, with groundwater making up the remaining 3%.
Indah Water Konsortium Malaysia is Malaysia's national sewerage company, and is in charge of handling the primary sewerage system in Malaysia. IWK comes under the supervision of the Housing and Local Government Ministry, and started operations in December 1993. IWK also ensures that waste water is treated according to prescribed environmental standards before being discharged into the public waterway system.
