Basically, the grid was built with the assumption that plants produce power, and that households only consume it. That means opening a breaker between the transport grid and the distribution lines should allow to safely work on the consumer-bound side.

That assumption no longer works if consumers energize the network, and while I assume workers have safety guidelines to check the line before starting work, there is still a risk.

Fixing this issue would require new remotely-operated breakers to be installed, which is costly, and it's hard to justify installing them proactively just in case.

I have been wondering if there is a smart way to make use of "island" solar at home, but not thought of one other than heating assist (pipe tape heater).

Governments have conflicting goals. You think "raise taxes" is the most important goal. But, believe it or not, some governments -- even conservative ones -- also have goals like "protect the envirnment".

In Germany for example, you are nominally required to register your balcony solar. Online, no fee. So it's easy. But .. there are no fines attached if you don't do it. And they don't ask for any taxes.

They are HAPPY that you do your local electricity power after Putin turned off gas export and it turned out that LPG import is way more costly (due to cooling and pressure, a lot of the stored energy is used for that during the transport/processing on that).

In Germany, there was even a process where the politics told the electrical engineers to not be so anal about electric security to make plug in of these devices into normal sockets a possibility. The VDE only wanted special sockets to be used. The politics said "Nope, too expensive for the normal people".

The idea that legislative and executive is only working AGAINST the people is invalid.
