You don't need a smart meter to do demand-based pricing. You just need the electricity company to publish its pricing plans in a consumable format.
In fact most smart meter usage to date is reactive; customers have to first use electricity at peak times to learn that it is peak time and then modify their usage. And if the pricing schedule changes you'll be caught out again until you adapt.
