In the UK, yes. You can see a UK smart meter being taken apart here [1] with the GPRS module shown at around the 2 minute mark. And you can look at meter datasheets [2] which list GPRS WAN as a feature. Smart meters often send a reading every 30 minutes. Some energy companies will then show a breakdown on their website that purports to show how much you're spending on lighting, fridges, appliances and things like that [3]. I suspect they use a lot of guesswork to arrive at that breakdown, given the limited input data. Although it's probably fairly easy to recognise certain multi-hour-and-distinctively-large loads, like EV charging and heat pumps.
