Since it’s only a few buildings in each of the two cities, we’re probably not talking about a large number of electrical utility customers. I’d say the chances of any of them wnting a smart meter is quite low. Even if they did, uness their energy supplier can accomodate them, they’re simply out of luck.
Here is the background info on the voltage conversion, which will take place over the next 25 or so years. Smart meters will be installed here with 12 million forecasted by 2030.
A big job. For your emon system, it will probably mean only replacing the a.c. adapters and checking the calibration. Of course, the UK has traditionally had a 240 V supply whereas the European standard is 230 V. That’s been dealt with by changing the tolerance in the specification!
