One thing which has not been mentioned in this discussion is that the wholesale market price of power at any given time is substantially driven by the marginal cost of generation.

When renewables (including storage) can't take up the entire load of the system, that marginal generation is nowadays going to be gas power, and right now the global price of gas is unprecedentedly high.

To simplify things somewhat; the larger the fraction of the time gas generation can be turned off, the lower the annualised price of electricity will be. At the moment, we are already seeing renewables taking up 100% of the load for short periods. As more renewable capacity gets built, those periods will get longer and longer, this effect will get ever larger. In some countries this effect is expected to become significant within the next five years, even at current rates of progress, and will only get better as time goes on.

Lower annualised electrical prices will be good for the economy and the individual, and encouraging this should be a priority for any rational government which thinks more than a few years ahead.
