No Standing Charge Electric Tarrif

[steelman99]

With the recent increase in electric prices , we've had another look at our bills.
We have solar panels and a battery storage system so for most of the year we only draw a minimul amount from the grid
For March and April we have been virtualy self sufficent for electric, only drawing around 0.5-0.7 KWH per day. we usualy draw a small amount ehen we boil the kettle an d thats all we use

Our smart meter is showing a daily usage of 60p per day of which 48p is standing charge.
Have looked at Utilita's Smart Energy tariff which has 51p for the first 2 units per day , then 27.35 per unit after that

We are seriously considering it as it would reduce our daily charge from 60p per day to around 26p per day . They also do a gas tarriff along the same lines which would benefit us in the summer , but not in the winter

Has anyone had any dealings with utilita either good or bad , and is anyone aware of any other No standing charge tariffs

Could you give a few details about your battery storage system?

I think it's everyone's dream to be self sufficient and free of the 'Trotter Trading Company -New York & Peckham' utility companies.

But of course, as soon as we are, they will find other means of taxing us.

Could you give a few details about your battery storage system?

A Tesla "Powerwall" I would imagine, although by now other brands are probably available.

as Ive been asked for details of our system

We have had solar panels on the roof for quite a few years and was happy with the decent returns from the feed in tarriff . Only when we got a smart meter did I realise how much we were sending back to the grid

The System is AC coupled so we dont loose any FIT, its a lux power system with 2 plyontech batterys - total storage capacity is 4.8KWH . Its only been installed a few months so how effective it is in mid december I cant comment, but our house faces south west so we dont get a lot of sun in a morning .

Been checking in a morning and the battery is still at 49-50% capacity and by lunch time its at 100% - in the afternoon we still send power back to the grid.

Cost of instalation the system was £3400 , according to the online monitering we've had the system 2 months now and bought in 13.8KWH, and sent 229.2 KWH back to the grid. Total household usage over this period has been 187.8 KWH so a saving of 174 kwh

Thanks for a great real world example!

Any idea why you are taking anything out of the grid, if you're at 50% in the morning?
Is there something that's permanently powered from that side? or is it because some days the battery is exhausted?

I've done more of this budgeting stuff than I care to remember for various types of commercial (stand alone remote) solar powered installations (generally telemetry in places it takes a long time to drive to) and it's great to see that the principles apply equally to more traditional power use.

All those numbers are variable and depend on many other factors such as the inclusion of charging an electric car, cooking by gas or electric & wether you use electric to heat domestic hot water etc, etc.

No the batterys have never been exhausted , Im assuming that something in the system limits the ammount of power the batterys can give out at once , and the spike in demand from boiling the kettle (its one of those one cup things) i more than the battery can give up at once.

That sounds believable.

I imagine you can balance the configuration of the inverter limits with different concerns; allowing sustained high current, or deep cycling the battery could age it quicker.
