Living at the edge of the grid, a distant community in Western Australia experienced severe power quality and uptime issues. Bush fire, a natural disaster common in the area knocked down the poles and overhead lines, with a high cost for the local utility to restore and maintain. Thomson Solar and Schneider Electric partnered to create a solution by powering the community with a standalone off-grid system. This solution is replicable to all small and mid-size dwellings living at the edge of the grid suffering from power-quality issues and where utilities must invest a large amount to maintain the commitment of reliable power for a small customer base.
As the homeowners were electing not to reconnect to the local utility grid, the system had to meet certain operating standards. The goal was to generate electricity on-site independently of the grid, using storage to assist in operating large three-phase loads while also providing power at night and during cloudy conditions. The system was designed to provide grid autonomy, yet with no undue inconvenience for the homeowners.
Schneider Electric provided a solution at a fraction of the cost of replacing power poles and overhead lines. The entire system is self-contained, and was deployed in a short time frame to restore power to the site. It shows that solar energy can be more cost-effective. This, in short, is the promise of standalone energy systems.
