In a world where the electricity grid lags behind technologically, the reduction in the cost of solar energy and storage makes it economically viable to produce as close as possible to the places of consumption and to integrate storage systems and sometimes additional ones in order to save on building new networks and lower electricity prices for specific consumers. Of course, the issue is tailored to areas where the land is fenced or a storage facility is possible to build, and less so to huge, central cities where the land is very expensive.
