Power Sector in Singapore is in the midst of restructuring and privatization, to convert a monopoly sector into a competitive sector and the utilization of cogeneration and trigeneration technologies.
At present, two subsidiaries of the state owned company Singapore Power, PowerSeraya and PowerSenoko along with Tuas Power are generating electricity. While PowerGrid, another subsidiary of Singapore Power, maintains and operates the country's electricity transmission and distribution system.
In 2001, a regulatory agency the Energy Markets Authority (EMA) was established. Today most of the state owned utilities generating capacity has been converted from fuel oil to natural gas.
Singapore electricity sector is a role model for the other countries in Southeast Asia. Singapore is also liberalizing the gas market and encouraging greater use of natural gas. Currently Singapore receives natural gas from Malaysia and Indonesia via pipeline, and is in the process of phasing out use of manufactured gas by consumers and businesses in favor of natural gas.
The authorities are looking at LPG as an alternative source of energy. At present, over 60 per cent of electricity is generated by gas.
Power Generation Efficiency
Since the liberalization of the electricity market, power generation companies have moved towards the increased use of natural gas. From 2000 to 2006, the electricity generated by natural gas has increased from 19% to 78%. As a result, Singapore’s overall power generation efficiency has improved from 38% in 2000 to 44% in 2006.

Cogeneration and Trigeneration Technologies
Cogeneration and Trigeneration Technologies will help companies significantly improve the efficiency of generating power and utilities like steam and chilled water. During the power generation process, a lot of heat is produced from the fuel combustion process. In most power plants, the heat is not captured and is wasted. But in co generation, which is also known as combined heat and power, the waste heat is captured and used to generate steam, this steam can be piped to companies and buildings that require heating. Cogeneration technology can increase energy efficiency from 50 per cent to 75 per cent.
