DESNZ: Over 22,000 domestic batteries installed in past year

That's really starting to add up. Nice.

That's really starting to add up. Nice.

Yes, it's good news (and I am one of them) but surely it's just a first step and actually only a drop in the ocean?

I think that - especially where there is surplus RE (Scotland's wind?) - British Energy or the grid ought to pay for batteries to be installed in houses locally just to mop it up... It might even be cost-neutral if you could avoid paying for curtailment.

I feel very much the same. A subsidy or contribution towards battery install would be nice. And not out of charity, but because everyone benefits.

I too think starting locally to excess generation points is best and smart, but demand side batts anywhere help us all too:

Gov gets help towards meeting CO2 targets (as RE deployment will be a bit easier).
Energy generators are able to shift more excess.
Grid operators (transmission and distribution) will see better and more balanced use of the networks.
Leccy supply companies, will see domestic demand smoothed out, which should help them reduce the need to buy expensive peak leccy, especially where they have fixed price contracts with us (the vast majority of us, even on variable price deals, don't actually have real time pricing).

So every party will benefit from a consumer buying a battery, and a small contribution would encourage more deployment.

The above might still happen when they realise they have to meet the net zero deadline.

That would be too forward thinking for any politician.
Then you’d have all the anti climate change mob spouting on about how much co2 is used to produce a battery and how all the figures are fabricated in favour of green energy.
However how handy would this be

Intresting video spoilt by those presenting constantly mixing up the units for power and energy, you would have thought that those working with electrics day in day out would know when to use kW and when to use kWh.

This report shows 3.6GW of BESS in the U.K. currently with plans for over 7GW by 2030.

Don’t know if that figure is just grid-scale commercial BESS or if it also includes the smaller domestic installations.

As usual, from these reports these days, there is no detail as to the energy storage.

Not one mention of ‘GWh’ in that report - so one might say it was about as useful as a chocolate teapot.

Would Dinorwig be as useful if its operational period, at full power, was one hour, instead of five hours? Dinorwig might be regarded as a BESS, after all - just not stored as chemical energy - and not separate cell make-up.

Domestic BESS is simply a few years behind domestic solar panel installation - there was likely little interest in helping the grid back at the time when solar generation was in its infancy.

The grid scale batteries are usually in kWp with a max capacity for a 1 or 2 hour duration at max capacity.

The latest ones are almost always 2hr duration now.
