2.2.3 Generating Station A generating station is an industrial facility that generates electric power. Generators found convert mechanical power to electrical power by creating relative motion between a magnetic field and a conductor. The energy source harnessed to turn the generator usually consume fossil fuels and natural gases. Cleaner renewable sources is also adopted in Malaysia through the use of hydroelectric, biomass, wind and solar.

2.2.4 Substation Substation is part of an electrical generation, transmission and distribution system. These units are generally owned by TNB. It is equipped with transformers that transform voltage from high to low or vice versa depending on the requirements and may pass through numerous substations before reaching the consumer.
2.2.5 Transformer A transformer is an electrical device that transfers energy between two or more circuits through electromagnetic induction. It functions as either to increase or decrease the input voltage in a system. This unit found inside substations can installed by TNB or the respective owner depending on the needs. Transformer can be classified into two types, step-up transformer and step-down transformer and further classified to oil-based and dry type transformer. However, the transformer identified in Setia City Mall is a dry resin, step-down transformer as smaller voltages are required.
2.2.6 Battery Room Battery room house batteries for backup or uninterruptible power systems in the case of failure in the main system. It provides standby power to operate computing equipment during emergency.
