Talk Morgan Forums Community The Malvern Arms Smart meters and solar pv

Ken,

I consider Smart Meters are, at the moment, pointless.

Why?

Certainly they are of benefit to the supply company, as they remove the need for a meter reader...but it is unclear if, should you change supplier, if the new supplier can access the smart meter. So until Smart Meters are "universal" they only help discourage change.

All the other reasons touted by the supply company are spurious. I really don't need to know, moment by moment, how much power I'm using. The meters don't in my view, provide data that facilitates sensible management of consumption. We use the power we need, we have LED lights almost everywhere and we mostly turn off devices we are not using.

I will decline a smart meter if and when offered:

We have solar PV and have just had a smart meter installed.
Does anyone else here have the same as I need to share an issue.
The intended benefit of the smart meter (for me as a user) is to be able to monitor consumption by individual appliances. However all the time the solar PV is generating, the indicated "consumption now" is reduced by the solar PV generated, often showing a negative consumption. As the solar PV is constantly varying, it is impossible to monitor the consumption of any appliances.
I have spoken with E.ON, our supplier but they are useless and failed to resolve. I have also been in communication with SmartEnergyGB, but they also could not help.
Ideas?

Sorry to say Peter you are 100% wrong in this regard. Have a look at the 'Faster switching' initiative and how the DCC uses the smart technology to make it easier, not harder to change supplier.

If you're not interested in optimising your energy usage then a Smart meter is probably not for you, but you'll end up paying more for your power. It's true that Smart meters reduce the measuring and billing costs for suppliers, and they will be able to reflect that in their tariffs. Customers who choose not to take advantage of the technology will naturally not be able to benefit from the reduced rate tariffs.

There are lots of companies out there developing smart apps which use a combination of appliance databases and smart data to give a live view of your energy consumption at 15-second granularity.

Current pilots are using standard appliance profiles, the next generation will know the specific consumption profiles of particular models, so you'll be able to see how much an AEG 123 will compare to a Zanussi XYZ for your particular usage pattern.

KenA: for your particular requirement, I would think a monitoring plug as Alistair and others have already suggested would be the way to go. If you want to get really technical about measuring the true consumption of appliance, you'll need to read up on Power Factors. Devices like Fridges and Freezers quite often take power out of phase with voltage, meaning they appear to use more power than they actually do. Simple monitors are unable to measure this so they don't give a totally accurate view.

Thanks I have PV panels and my provider is pushing for a smart meter.

Quite surprised that when you have panels or other generating devices fitted as a matter of function that there aren't multiple reading points to give an accounted balance.

There are cases where people have been supplying their neighbours, a guy I work with had had this problem when he lived in Andover.

It probably wouldn't take much to fit another meter on the consumer side but obviously that would be at the customers expense no doubt as it's of no benefit to the supplier.
