"Load control? Unless the rollout is even dumber than I've heard, that's not done by cutting off power at the meter. It's done by selectively cutting off individual major loads, usually an immersion heater."
How could it possibly do that? The smart meter in on the wires coming from the company fuses and going into the consumer unit. It's all or nothing. You would need a smart consumer unit to selectively cut power to individual circuits.
All a smart meter can do (in the future) is allow power to be bought with an expensive high reliability tariff or a cheaper low reliability tarif that gets turned off when power demand exceeds supply.
