Trying to make out if this is good electric rates or not???. Certainly different.

[Collectors]

Just been looking around for a better electric deal as my lecy has gone up 19% off-peak & 39.7% peak. Now most households tend to use a lot of electric between 3pm & 7:30pm & of course that's why the lecy companies have their high rates at these times, including the one below. But would be interesting to see if you could make it work in your favour.?? Its certainly different way of pricing, & i like differant. 100 green.com

That’s certainly an unusual pricing structure! I’d work out the cost using your actual half-hourly or hourly consumption rather than just comparing the headline rates. If you can shift the washing machine, dishwasher and EV charging (if applicable) away from the peak period, it might work out well, but the standing charge and the expensive 3pm–7:30pm window could easily wipe out the savings. Have you compared the rates against your current tariff using a typical month’s usage? That should give you a much clearer idea of whether it’s worth switching.

Seems too good to be true. I’ve just got a quote from them for medium usuage (which they have estimated lower than my actual use) and it’s £159 a month. Recently changed to British Gas and as I said, I gave them my actual use. My monthly standing order with them is £105 per month.

From around 10 am to midnight my use is near to zero at the moment, I rely on off-peak however for the bad days. The export at 12p/kWh I get at the moment is the make and break point. And the main thing is how ones inverter can be programmed.

So at 8.21p/kWh off-peak, and 12p/kWh export I can set to charge batteries to full, and even if no space in batteries during the day for solar, I am still gaining.

OK if batteries run out 30.74p/kWh until 00:30, but I would hope this time of year they will not run out very often.

So last month bill was just under £6, this month already spend around the same, so looking at 2025 no details for before April but £64.48 for April onwards is not too bad. This year can't get software to show price, in kWh it is -951,075 kWh.

Jan to April this year cost £114.37 so Annually the bill around £180. It will be more now as export dropped from 15p to 12p but to my mind the 19:30 to 22:30 at 15p/kWh would be an advantage, but the 03:00 to 06:00 is too late most days, and if export is less the 15p/kWh one would need to be very careful not to charge up the batteries too much.

So if no batteries or solar, it would require a lot of careful use, and I would say it would be very good for heat pump users.

With solar only, one is in the lap of the gods, as you can't predict when you will get solar.

With solar and batteries, it will depend on battery size, if we still had 3.2 kWh battery it may have helped us, but with 6.4 kWh it is unlikely to help.

Do you know when you use the most electricity each day? If you’re out at work during the week you’ll hardly save anything during the day and get penalised when cooking your dinner

My consumption yesterday. seems only 3 cups of coffee, but the question has to be, can I change the use enough to line up with the off-peak times, and that seems unlikely.

So we look at power use, freezer and fridge, reasonable even through the day, the washing machine, tumble drier and dishwasher, have delay functions, so we can set those to run off-peak, dietitian tells us when to eat, OK may alter a bit, but cooking tends to be between 15:00 and 19:30 even if dinner eaten after 19:30 it will likely be cooked before then, so 8:30 pm is a bit late to eat dinner, so what can I move?

And that's the point, the only thing one may be able to do, is move when heating comes on. Last week, as sun goes down, it has been getting a little chilly, and I have started using an oil filled radiator, which does stay hot for some time. This month used 5.2 kWh, used once yesterday

bang on the expensive time. So the one thing it may help with, is under floor heating, it takes a couple of hours to heat up, so will 12:00 to 15:00 last until 19:30 well this time of the year, answer is likely yes, but as we get into winter, that will change.

I'm retired & home a lot of the day. My problem is i rent 3 rooms out, so it becomes an od one to work out. But with all of us, the 3 to 7:30 is a busy kitchen period & we are all electric except the LPG heating. I got solar & a 30kw bank of batteries, but we are near that time of year where the charger will be used more often.

At 30 kWh the tariff may work. For me, the rub was the tariff tied me in for a year, so when I found that in my case British Gas were unlikely to ever pay me for export I was 6 months into the tariff, and it seemed likely at that time of the year, I would not get the £75 back by moving, so in all, waiting for smart meter etc, I was 20 months with no payment for export. You have not said what the export is being paid at.

I am assuming 30 kW is an error and you mean 30 kWh?

 

[Collectors]

.I don't export, i have found lecy company's such a pain "Like you have experienced" to deal with, i just don't bother., if i could, i would look at ways to sell to my neighbour, & make more from it. On the batteries, i have 2x48v 15kwh banks in series wired tegether in parallel

Your 30 kWh is far larger to my 6.4 kWh, and I question why you need a supply from the grid?

My 6.4 kWh will not discharge to less than 10%, so 5.76 kWh is useable. My use is around 12 kWh per day, and my panels are 6 kW with a 5 kW inverter.

So summer purple line is the state of charge of the battery, so here from 10:20 to 19:20 my battery stayed full, this is OK when I am paid for the 21 kWh exported, but if not exporting then the dip at 7:30 needs to hit the 10% mark, not as shown 88%. I imported 6.5 kWh which if not being paid for export, needed to be zero import. But batteries could only take 5 kWh, so I would have to imported 1.5 kWh, but near impossible to work out the day ahead, and so how much to import over night, so answer is to do what you have done, and have a larger battery.

But

does not matter how big the battery is, 30.8 - 12.6 means 18.2 kWh has to be exported, that's £2.18 I would have got for that, actually £2.52 the 34p cost me, 24p earlier in the day, so I don't need to worry about importing too much as I gain 10p.

I just can't see how the solar and batteries pay for themselves with no payment for export.
