Thanks for that information. I thought that it would be possible to set up a meter to switch automatically based on its internal clock, but my concern was how does that internal clock keep good time if there is no communication possible. Its the timing that RTS supplied, and I think a mechanical clock back up inside provided additional switching in the event of power cuts.

If its so simple why can't they just say that in plain English.?

All smart meters have an inbuilt battery backed clock. That clock is set when the meter is installed (the meter tech uses a program on a laptop/palm top) and the internal battery is usually good for the life of the meter. Same as a cheap Casio digital watch, or the BIOS in your computer.

The battery only ever needs to hold up the state of the clock, which is crystal controlled the same as any digital clock, for the times when the mains power fails. Yes, it will drift a little , but accuracy of time switching in electricity meters only needs to be +/- half an hour and the drift is probably only a minute or two a year.

Obviously, a connected and communicating smart meter can request a time reset after a power failure, which a non communicating one can't, but the built in battery backup usually takes care of most scenarios.

I will challenge the premise that standard meters aren't made any more. Of course they are. The UK is about the only country in Europe that went down the smart meter route. Most of the rest of Europe, and most other 230v 50Hz countries still use normal meters so the manufacturers are still churning them out. So the 'we can't get standard meters anymore' is nonsense.

And just for laughs, Germany, France, Hungary and a couple of others still in Europe use RTS and other countries are rushing to adopt it. It's just the UK that is the outlier here. But that's what happens when you put politicians and quangos in charge of things.

If that is the solution then no-one will say that because it would potentially harm their continued rollout of smart meters, it's not exactly being lapped up by the public as it is. If there is no mobile coverage then they can only fit conventional meters or dumb smart meters as far as I can see.
If they say that's what they're going to do then others may well say "Well if they've got one then I want one etc", it looks like they're saying as little as possible in the hope that no-one notices.

What they do seem to be saying is that the switch off of RTS will prevent their current meters from switching from one tier to the other and back again, so their two tier tariff will no be meterable any longer on the old equipment, so the meter needs to be replaced. And it can't be replaced with a traditional meter because that will just is bad as what they have now - it just will not work. So a smart capable meter is the solution.

I would encourage all those still with functioning RTS equipment to get their meter swapped ASAP if they want to retain E7 or similar pricing.. While I don't think the Smart Meter programme will deliver its claimed benefits to the vast majority of customers, and overall is a waste of our money (because we're all paying too much for it), in these particular circumstances, swapping to a smart capable meter is the right choice, whether it actually delivers smart functionality or not.
