Whenever an electrician installs anything like an AirCon etc they are supposed to notify the supply authority to allow them to ensure the network is adequate.

Solar is having a huge unreported impact on the electrical network, areas where there were problems with the voltage being to low are now suffering with the voltage being to high with the seer number of local generation sites feeding into the grid.

Blackouts in summer aren't caused by power lines melting due to overloads, you might get a connector failing, or a piece of "bridging" but not the lines themselves. They do melt if they get hit by lightning but then so do most things.
