Which goes half way to demonstrating the point - if they stick to thecreliable types (Feraris disk for lecky, bellows for gas) then the meters are quite rekiable and go on for years. With the electronic versions, it's obvious they they have a much shorter life - but 3 in 12 years is taking the urine
True, but that clock is never going to get turned back. However, I'd say that it also goes more than half way to demonstrating the point
I was making - that if they are changing non-smart meters at anything like the rate I've experienced, then the marginal additional cost of
installing smart meters ought to be pretty low (and only a small fraction of £11 billion).
[by the way, "3 in 12 years" makes it sound a bit more than it actually is. As I said, I' 'on my third' in those ~12 years, but the last of those was installed last year, so it's likely equivalent to something like "3 in 17 years" or thereabouts. ]
The latter does not require the former. All that is needed is one register (and reading) per charging rate used in any billing period. Given the cost to us of collecting and storing this data - and keeping it secure - you have to wonder what thecreal reason is.
I've never really understood the point in smart meters having multiple registers (or, indeed, if the communication were faultless, any registers at all!!). If they simply uploaded usage and time data, they could play around 'centrally' with how much they were charging for usage during any particular time window. ....
... even my OWL system has an 48+ hour local buffer (and that's with ~12 second readings - so roughly 17,000 data points per phase per day) - so if I lose communication (in my case, the internet connection) for a hours, or even a day or two, no data is lost to the server.
