Where is Storage Needed?

Is electricity storage a good idea? Where is it needed?

• In the countryside, where the solar and wind power are generated?
• Or in towns and cities, where most of the electricity is consumed?

Peak demand is an issue in the cities, but handling PV on a sunny day is a rural issue - so we probably will need both - but the more we shift our demand, the less expensive storage we will need - happy time-shifting!
