You don't need storage if you have enough non-intermittent power to satisfy peak load. Canada uses 1,500 GWh of electricity per day. 12 hours of storage is 750 GWh of storage. Estimated for grid storage costs range from $125 to $250 per kwh for fully installed and connected systems (not just the cost of the cells alone). At $200/KWh Canada would be looking at $150 billion for 12 hours of storage.
