I’m sorry, I think you may not be using ‘baseload’ correctly. We will absolutely always have to meet the requirements for baseload power generation, otherwise we aren’t making enough power and we will have brownouts.

If what you meant was that a grid relying on solar and wind for primary generation and supplemented with battery facilities can make up the deficit at night/on calm days, then while that would be ideal it is extremely unlikely to happen in the next several decades. Battery technology is not anywhere near ready for this solution, and while ESS are making extremely impressive advances, they are such a new technology that it would be intellectually dishonest for me to list their shortcomings here. They are simply too new to know which problems are inherent to the concept, and which are due simply to flawed engineering of a new technology.

For matters of logistics, a few large generating sources linked together are much more desirable than a distributed network. In fact the issue with economies of scale in power generation is one of the arguments against SMRs made by the above linked article’s author. One of the biggest concerns with truly distributed power generation is safety - namely, how can you safely work on a downed line when every single house has the independent capacity to energize the lines? But those large power generating stations run into the same issue that SMRs are in vogue to solve; what do we do about crypto miners besides grinding them all up into dog food, which gets my vote. Their drain, and those of industry and data centers and so on, on local power infrastructure remains despite the source of the power in the system.
