Less electricity storage means the need for larger transmission lines, as peak loads become larger. In general better aligning utilization with surpluses of electricity carries an intrinsic tradeoff versus the capital cost of oversizing the utilization equipment to make up for only working part of the time. And the real way to look at storage is pure electricity storage versus storing the output products of electricity. Like I can run my washing machine when the sun is shining, because clean clothes (product of electricity) are going to sit around for a week anyway, which is free storage. Whereas if say you run a desalinization plant only when the sun is shining, then you have to store the fresh water in tanks for when people actually want to consume it (in addition to doubling/tripling the pumps/membranes). Transmission lines are going to fall in a roughly similar category (modulo consumption local to generation), where now all that oversized utilization equipment is drawing twice as much during the day and very little at night, increasing the sizing of the lines.
