That's pretty much the crux, and puzzle, of the argument for nuclear though. The Liberal party, long the bastions of free market and small government ideology, are very much in favour of individuals choosing to buy solar systems for their home. Indeed, between now and whenever a future nuclear plant becomes operational many millions more will be installed on homes and businesses.
South Australia is already seeing problems with too much home solar generation. They are export limited, so can't send it to other states efficiently (but building a new interconnect as we speak), and are at the front of the curve when it comes to inverter level control of individual solar installs by necessity. This is the catch 22 of new nuclear. There is already a demand for creative solutions like load control, community batteries or "other" that will solve the problems around "too much" solar well before a nuclear plant can come online.
