Why not? Its just a function of availability/price. Assuming some conservative numbers of 1kwh of batteries costs 100usd and can do 2k cycles, that results in extra 5cents per kwh. With the day/night cycle the utilization could be around 50%. Offset by only roughly half of your electricity needs to be stored. Sunless days would be pain though. Imo if combined with cheap solar can be competitive. FWIW my current electricity provider already applies a 1 cent/kwh surcharge for "peak capacity assurance".
