The latest meters in Dubai are much smarter. No more meter reading, all done remotely (no more meter reader jobs) including power supply on/off and if your water or electricity meters detect unusual excess usage, then you get a sms from the supplier.
These so call remote reading 'smart meters' are all over the country now. I think Victoria mandated an upgrade to 'smart remote reading interval' meters sparking an entire backlash over how these 'smart meter' were frying people's brains and people wanted the right to refuse this installation! (Also didn't help that some retailers tried to force customers onto 'time of use' plans when the customer had the right to stay on fixed tarrif plans.)
I've had a multi-register (peak - off peak - solar feed in) 'interval meter for over 10 years. The meter reader downloaded it using a 'wand' that optically coupled to a data port on the front of the meter.
When the gross feed-in tariff ended, the meter was replaced with another interval meter that has a 3G modem module attached and it's now remote read and can be reprogrammed remotely. It's been in place 3 years now on a wall that faces the master beadroom and my brain hasn't turned to mush. Yet.
The time stamped 5 minute interval data is downloaded and the appropiate tariffs applied by processing the data.
A couple of years back my work moved into two newly refurbish buildings. Both buildings have remote read 3 phase interval meters. There was suffcient mobile phone signal in the switch rooms that the mobile antenna is just on top of the equipment rack in the room, they didn't need to run to an external antenna.
(Also the lift emgerncy phones are also mobile phones, with the antenna just on an equipment box in the top of the lift shaft. Again, enough signal that an external antenna wasn't required)
Remote read 'smart' interval meters are now the norm.
Note many large and industrial customers are on 'peak use' plans were their maxium power demand sets the price they pay not the actual consumption. A lumpy load like charging a train or tram at regular intervals could lead you to pay a max demand premium (as the supplier has to engineer for your maxium demand, not the average!). In these cases having a local fixed battery or capacitor bank to take the peaks off your demand can lead to significant savings, even if the actual kw/hrs consumed doesn't change dramatically. It's all about reducing that peak.
The Byron Solar Train may be on a peak demand tarif because of what the nightly battery charging does to the grid. Although there is time for the train to do a 'gentle' charge cycle on the train traction batteries.
The Newcastle trams will almost certainly be on a maximum demand tarif, with those flash-charge hits every five minutes or so all day.
Any plan now to extend the route of the solar train will now lead to conflict with the 'rail trail' mob, who won't want to give the corridor back once they get their hands on it.
