Why Stand-alone Power Supply (SPS) Systems?
In large parts of WA where there is no electricity supply, thus there is a need to supply your own power. These systems are commonly known as Stand-alone Power Supply (SPS) systems, as well as Remote Area Power Supply (RAPS) Systems. Western Australia is one of the largest states in the world. It is larger than many European and Asian countries. Most of the state also has a low population density (few people per square kilometre). For this reason, it is very difficult and expensive to provide a statewide grid. Two main grid areas exist, the South West Interconnected System which is shown in green in Figure 3 from Western Power and the Northwest Interconnected System (yellow). Most larger towns in WA also have their own smaller distribution systems which are either owned by Western Power or a private electricity provider. In locations outside of towns, or where there is no distributed electricity, people need to produce their own power for their homes and businesses.
