free Smart Meters


First Utility are already supplying free Smart Meters. The benefits are in having the data to see how much of your generation you have and have not used domestically - see previous thread.







Economy 10 tariff provides 6.9p/kWh off-peak import between 12am-5am, 1pm-4pm and 8pm-10pm; http://www.pvoutput.org/aggregate.jsp?id=21047&sid=18934&v=2&t=m on approx. 63% off-peak usage, 22% solar usage, and 15% peak-rate usage.
1,900kWh annually is exported, mostly in summer, on approx. 3,200kWh generation. Approx. 4,500kWh/year is imported, mostly for (a) winter and springtime off-peak Storage Heaters, and (b) off-peak hot water Immersion heating (which is “dumb”, i.e. not linked to the solar PV).
PV array is split East-West. Income is from Phase II 21p/kWh Feed-in-Tariff plus smart metered 3.2p/kWh Export Tariff.

British Gas are also supplying free Smart Meters now. Apparently the other 5 big suppliers should be amenable too.

free Smart Meters


Note that the current Smart Meters are proprietory and connected to proprietory communications hubs and proprietory back-ends. For example, the ones being supplied by British Gas are connected to the Tilliant Communications Hub.


In contrast, next year's full-scale Smart Meter rollout programme will feature interchangeable and intercompatible smart meters connected to a comms hub run by either Arqiva if you are in Scotland or the north of England, or by Telefonica if you are elsewhere - see news story.


Hence, existing smart meters like mine are not compatible with the intended two new standard comms hubs.

free Smart Meters


Hi Roger,


             Had a quick look at First:Utility website you linked to but can't find anything about smart meters and in particular ones that are free and give export data. My current supplier Eon offered me a free smart meter but when I spoke to their FiT and Smart meter departments it became clear that there was no export metering or display functionality. Eons offer was based own their own smart meter system but even if one waits for the national system rollout I think the document I identify in a new thread (Smart Metering Technical Standards) shows that the ability to see export data will not be part of the requirement on suppliers to provide free of charge. So, I would be grateful if you would point out any more precise info on the First:Utility site.

Mmm, thanks for the update about First Utility, Rick.
I see that Eon like British Gas are bundling in a paired Gas smart meter and, like your good self, I'm rather attracted to that idea too.


I wouldn't assume that the Eon bods you spoke to had the meter specification to consult when opining on the subject, and I've never heard of a smart meter ‘without export metering functionality’. But to find out the truth I would seek out the meter's installation guide (they're normally online somewhere or other) given the level of ignorance amongst utility suppliers.


N.B. I gather that Eon use the same Landis+Gyr E470 smart meter as British Gas, but without the Zigbee-compatible online customer portal of all your smart meter data that British Gas provide.

Apparently the Landis+Gyr E470 does indeed record export.

As I already know how much electricity I have and have not used, what is the fixation with smart meters? We will have to wait and see if there is any advantage to them!  “In This Day And Age, It's Hard To Tell If All Internet Quotes Are genuine”. Abraham Lincoln.

free Smart Meters


Hi Capetown,


                  I only have a generation meter at the moment and was wondering if the rollout of smart meters would offer a free means of metering my export that would be recognised by my FiT supplier. I suspect that I export more than the 50% default assumed for domestic installations without an OFGEM approved export meter. If this were confirmed, I would try and claim actual exports.

Smart Meters (or Export meters) also allow those of us on the more attractive metered Export tariff - instead of merely the ‘deemed 50%’ - to completely opt out of the measly Export tariff in favour of selling our exported ‘leccy.
Ovo are the only company that I’m aware of that offer to buy micro-generated electricity, and I don't imagine that the price offered is exactly anything to shout about. But us metered Exporters do at least have that option, and I would expect more retailers to make offerings to us micro-generators as the FiT scheme winds down - as indeed it has already this year as regards new solar installations.

As regards Capetown's comment, I don't think that most rooftop solar households are, in fact, aware of how much electricity they have used and have not used, let alone anything else. I didn't intend to be controversial - just to provide some info! :-)

If you want to be controversial that's fine by me Roger!
