And there is another way, that perhaps Joe Public hasn’t yet cottoned on to: Once we all have our super new smart meters, new tariffs could be introduced where at times of high demand, suppliers will have the facility to simply jack up the unit price for those odd half hours when they need to decrease demand! Easy peasy as smart meters are already sending back your consumption to the supplier, every 30 minutes.
And of course the other way round. Some suppliers are starting to offer negative prices for some times in the day. Do your washing at 2:00AM and they'll pay you.
