Posted By: jamesingramI've several clients interested in battery storage butt generally steer them away from it because it doesnt seem to add up financial at all and only slightly environmentally. Being paid to charge or very low charge price changes that and gives it greater purpose outside of summer solar surplus period especially helping individuals drop their peak load.Yes I have been thinking about what the benefit is but am not convinced of my figures. If you charge in min 3hrs and discharge in peak 3hrs, I think the raw cost benefit is 20p/kWh.
Posted By: jamesingramWouldnt you need to some decent automation to manage and kick in charging etc at price plunge.Yes but that is increasingly simple.
Posted By: Jeff BI presume a good mobile connection is essential for the Agile system to work though? What happens if the technology fails from time to time?Not all SMTES2 meters are connected via mobile signal - some are intended to rely on a local mesh and radio signals. However, until enough houses are converted the 'mesh' is not very good!

If it fails, it is not clear what they do. I'd present my measurement data and tell them what I owe!

I expect you wouldn't be allowed on an Agile tariff or anything similar unless you had a reliable SMETS2 installation.
There's quite good detail about the comms athttps://www.smartme.co.uk/technical.html" rel="nofollow" >https://www.smartme.co.uk/technical.htmlfor anybody that's interested.
Posted By: Jeff BThis may be a daft question but does that mean I would have to stay up all night to monitor every half hour?!!Not if you measure your consumption anyway.
Posted By: jamesingramIt seems (without looking greatly into it) heavy users might benefit from a battery /variable tarrif setup but really the money would be better spent reducing the overall energy use via insulation etc.For me. I could get a smallish 2.4kWh system, charge at low demand and discharge at high demand and recover the cost over 10 years while feeling good that I was helping to balance the load of the network. It isn't about making money. This house is pretty much as efficient as it can be in terms of insulation and air tightness. When the boiler get older, I'll look at ASHP.

Sorry, I don't understand. How can I measure my electricity consumption every half hour if the technology isn't working, other than by physically taking readings from the meter every half hour?

Posted By: Jeff BSorry, I don't understand. How can I measure my electricity consumption every half hour if the technology isn't working, other than by physically taking readings from the meter every half hour?I use the OpenEnergyMonitor system to measure my electricity and the software works it's magic (as seen above).
Posted By: djhI think tariffs have to be supported by revenue-grade metering.But we were discussing what happens if the metering fails. I can demonstrate with an accuracy of less that 1% what I use in each half hour period.
Posted By: WillInAberdeenSome of them are using a different radio system now that is more reliable than the mobile phone signal. Your supplier should be able to tell whether it will work based on your postcode.The radio technology used depends entirely on your location in the country not the supplier you use.
Posted By: Jeff Bit seems the Agile system uses ZigbeeNo, Agile is the tariff absolutely devolved from the technology.
Posted By: jamesingramInteresting product designed to maximise Heat pumps and variable tariffs benefits.
Is this one of the type of products we've been waiting to appear?

Posted By: nigelI have a zappi charger and they have recently added Agile specific functionality that allows you to automate when you charge, their system looks at the cheapest rates and charges in the cheapest half hour slots.
Quite often when its windy at the weekend the rates go negative.
