Camelot Members Annual Green Electric Generation

[nowty]

Its not your imagination that Summer demand was higher this year, I just compared June to Aug this year verses last year on Gridwatch and this year was 3.8% higher. But we have been exporting more this year.

Since mid June we have often been supplying the best part of 3GW to France which I don't think we have in previous years, that is more than 3.8% of demand - but do the "demand" figures refer to UK only consumption or is it just a total figure including the interconnectors?

I was trying to work that one out in my head and it just hurt.

My personal import for Summer this year has been the same as last year.

Zero, at least almost.

Zero, at least almost.

Mine was 100% less this year (zero) , but was round 1300kWh (June to August) in previous years

Aye, renewables and storage don't work do they.


SWMBO has helped me getting panels up, seen the insides of the battery cave and has walked up a Welsh hill in the rain to watch WT1 going round. A few weeks back she returned from work and asked me how much we paid for our energy because one of her colleagues was now paying £350 a month after it had doubled, and she wanted to know how much we save with all our panels and stuff.

I said "£1".

£1 what ?, per hour, per day ?

No, we pay £1 a month and to be honest that's actually too much.

No, no !, it cant be ?, what about charging my car ?

Yes thats included.

And how much do we pay for gas ?

Thats also included in the £1.

I can't tell her that !, she'll never speak to me again, she lives in a 2 bed flat and we have a detached house and have 2 electric cars !

By this point I was rolling around the floor laughing with tears streaming from my eyes.

Had a similar conversation with a neighbour recently. They mentioned that their electricity direct debit had gone up to nearly £300 a month. I couldn't help mention that ours was £12/month, mostly covering the standing charge. They don't use electricity for heating or hot water, either, whereas we do. I've looked at our credit balance and most likely consumption through the winter and reckon that we will still be very much in credit come next spring.

Update time and as before, I have added a new category of Energy Storage.
I have spent quite some time today trawling through more members sigs and I have found quite a lot of battery storage, EVs and thermal stores, in fact doubled it.

There must be more out there so if you don't have your home batteries, EV, hot water storage or storage heaters in your sig, please PM me with simple details.

In an average year 101 Camelot members will generate 509 MWh of renewable electricity onsite and 177 MWh remotely.

Onsite Generation
PV - 465 MWh
Wind - 42 MWh
Hydro - 2 MWh
Total - 509 MWh

Remote Generation via Coop's
Ripple WT1 - 40 MWh
Ripple WT2 - 133 MWh
Hydro - 4 MWh
Total - 177 MWh

Grand Generation TOTAL - 686 MWh

AND

The same 101 Camelot members have a combined 2,851 kWh of onsite Energy Storage capacity.

Home Batteries - 942 kWh
EV Batteries - 1,313 kWh
Hot Water Storage - 497 kWh
Thermal Mass Storage - 99 kWh
Storage Capacity TOTAL - 2,851 kWh


Keep em coming, there must be more of you out there generating and storing.
Publicly reply to this thread or PM me with your PV (kW installed or annual kWh), Ripple project, Co-op or other generation.
And now EVs, hotwater and thermal mass storage (like storage heaters).

OK, we have a 250L thermal store powered by the WBS and solar thermal, 250L DHW powered by solar thermal/WBS/and Gasser, 12 tonnes concrete slab with UFH powered by WBS via T/S and Solar thermal and Gasser.

If you can make head or tail of that you're a better man than me Nowty!!

To work out the sensible heat stored in a concrete slab it's close enough to assume that 1m³ of concrete stores about 2,122kJ/C°, about 590Wh/°C, and concrete has a density of around 2.4 tonnes/m³, so 12 tonnes is about 5m³. 5m³ of concrete that's, say, 2°C warmer than the room temperature, will store about 5.9kWh of useful heat, for example.

PS: Cracking job with the data, Nowty. I'll work through all our numbers later and post an update, in case that helps.

[Oldgreybeard]

Nowty,

Just worked through our numbers (you probably already have them):

Energy storage (thermal):

Hot water = 9kWh (Sunamp UniQ phase change thermal store)

Floor slab (~8m³ concrete), heated with embedded UFH = ~5kWh on average (can be anything from around 3kWh to maybe 10kWh)


Energy storage (house battery)

6 off Pylontech US3000C battery packs, roughly 21kWh

Energy storage (car battery)

52kWh


Electricity generation

25 off 250W solar panels (6.25kWp), limited by inverter to 6kW

Generation around 6MWh/year on average

PV self-use percentage 97.6% over the past 12 months

About 50% of the car charging has been from excess PV over the past 12 months and about 45% of the hot water storage has also been from PV over the same period.

Excellent OGB, I did have all the info from a combination of your Sig and your PM, but great for you to give others a classic example of the info I need on an individual basis.

So for example, the "secret list" entry for yourself, and it really is secret for info given to me by PMs but as OGB's clearly gone public, this is the sort of info I keep on the 101 (and growing) secret members and I update the info in my spreadsheet if I see members adding another EV or a PV extension or more ripple wind farm, etc. And for security purposes, unless I know you personally, I don't know anything about you apart from your nickname and anything you choose to publicly make known.
