Quick Reserve Auction Requirement Forecast

Quick Reserve, separated into Negative Quick Reserve (NQR) and Positive Quick Reserve (PQR), is aimed primarily for reacting to pre-fault disturbances to restore the energy imbalance quickly and return the frequency close to 50.0 Hz.

The service is procured via a daily auction at 14:00 for delivery between 23:00 and 23:00 D+1.

Not something for consumers, but new...

Sounds like Fast Frequency Response, which was a National Grid scheme that PowerVault were trialling at a consumer level a few years ago. Their batteries had the hardware built in to detect small changes in frequency so they could charge themselves up or discharge appropriately to help balance the grid. The principle is that if there is a sudden load on the grid, the "old-fashioned" spinning generators would slow down momentarily as they bogged down and regulated themselves which had the effect of reducing the frequency. So the batteries knew they had to start exporting while the generators caught up with themselves. A bit like a car going up a hill - it slows down momentarily until you put your foot on the accelerator to compensate. And vice versa the other way round, i.e. suddenly a load is removed the frequency increases and the batteries respond by fast charging to help out.

All clever stuff, but I think that scheme fell by the wayside though, or at least as PowerVault were concerned. If you were a PowerVault customer you got paid £10 per month, paid as £1200 for 10 years in advance, as a contribution to your battery.

There was a fault with the link to Norway (I think) the other day and the frequency response went down only very briefly (measured in ms) as a result of commercial battery services kicking in. With the expansion of such battery storage it'll be interesting to see how this impacts the domestic side.

I took part on Octopus' saver sessions last year, but of course those were pre-planned and  just exploiting the customers using less. Not sure how much domestic battery to grid has been signed up?

thanks for the background. They created a notification channel for it yesterday so maybe they are breathing life in to it.
