Our customers look to us to produce and deliver affordable, dependable and reliable energy.

Being a consumer of energy, Gas Malaysia requires clean, economical solutions to mirror the solutions provided to our customers. Hence, we embarked on becoming the first commercial establishment in Malaysia to utilise Distributed Generation technologies to better manage our energy costs.

On July 9, 2001, we commissioned the use of a Capstone Microturbine unit for power generation at our Head Office in Shah Alam.

Existing Power Supply

Our Head Office in Shah Alam obtains electricity supply from Tenaga Nasional Berhad (TNB), with a power consumption of 133kW on peak demand (320A / 415V).

The power is used for a multitude of electricity-based appliances and application, mainly in the lighting and air-conditioning of the building.

Tenaga Nasional's tariff for the building is categorised under Tariff B, which is equivalent to RM0.288 per kilowatt-hour. On average, our monthly electricity expenditure amounts to RM17,000.

The Implemented Solution

The distributed generation system used at our head office utilises a 28kW Capstone microturbine, which is operational 24 hours a day, which on average provides around 20% of the total electrical building load.

This system reduces the loss of energy in the process of transmission and distribution by between one and two percent. This means that around 99 percent of the energy generated will be available for consumption as opposed to the traditional system that requires long transmission lines, which are susceptible to energy losses of up to 10 percent.

Significant Cost Savings

The cost of generating power using the distributed generation system is RM0.175 per kilowatt-hour. This represents savings of up to 39 percent when compared against Tenaga Nasional's tariff of RM0.288 per kilowatt-hour.

Future Expansion

Gas Malaysia is planning on expanding this successful on-site power generation system to include Cogeneration (also known as Combined Heat and Power). Cogeneration is the generation of electricity concurrent with the recovery of heat, which would otherwise be wasted in a conventional generation process.
