In the business as usual scenario for Australian substations, or local electricity grids, the maximum amount of solar supported is around 15-20%. Once this limit is reached no more solar would be approved. The network is unable to support it. Businesses will not be able to install solar.
The statistics for the National Electricity Market (NEM) in this article show 50% of renewable provided to the NEM, and rooftop solar provided half of that. Australia is getting closer to this 15-20% limit on local substations, and connection agreements are being declined as a result.
There is an alternative, where every rooftop can install solar and benefit from selling back to the grid, without any affect to the network whatsoever. The award-winning eleXsys® technology developed in Queensland by industry pioneers that foresaw the problem.
By installing advanced Power Electronics devices, powered by Artificial Intelligence, on a customer premise (also called “behind the meter”) the potential of the entire rooftop, not just a portion is unlocked.
