With the accelerated uptake of renewables such as rooftop solar on Australian electricity, network connection agreements are becoming increasingly difficult to be approved. Why? It is the fundamental behaviour of these solar systems connecting the grid. Simply put, these systems create instability and affect every other company connected to the local substation.
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.
