If you can store energy in batteries for days wherever, and store energy for weeks in hydrogen anywhere bigger than a house, and store energy in ammonia for decades and move it wherever there are trained personell, and store energy in NaOH and release it as low grade heat, and store energy in methane and put it through the existing gas network, and all these things cost in the range of $20-100/MWh over and above the energy input... Do we ever actually need to move our $1-10/MWh peak solar energy through our $100-200/MWh grid?
