Axle bids in numerous energy supply / demand control markets. They'll only pay out for grid events in the time windows they "won" the bid to supply energy into. Which may not be the window of peak demand on a given day, if someone else (e.g. a good old gas peaker) won that time slot.

Similar for octopus, except octopus also have their own internal market balancing supply and demand for their own customers.

Given last night's event was out of the normal peak period of 4-7 pm, It's hard to understand(for me) how they can bid such high prices in a competitive market unless they are getting some sort of subsidy to be operating on a trial basis?? We're the guinea pigs for the trial and being paid to help out??

Just to add last night's event went off seamlessly with the Solis inverter reverting back to normal straight after the event.

But you also need to look at the bigger picture and the weather - no wind near us at all yesterday, no wind, no wind power, big hole to fill. Your just looking at the tea time expensive period, but other things happen.

 

I've had events 0600-0700, 0800-0900, 1700-1800, 1800-1900, 1900-2000, 2000-2100, 2200-2300. So almost any time of the day. But mostly morning and evening.

 

Axle have been operating quite a while now, they didn't start a couple of months ago.

I understand all of what you say but I'm trying to understand why there's a mismatch between the Axle event looking for grid support and the apparent lack of a need for grid support by Octopus.

 

If the grid needed supporting from 7-8 then I'd have thought Octopus would have been pricing to gain that support from their customers such as my mate who had spare battery capacity but didn't export because Octopus didn't price to encourage him to.

 

I appreciate Axle aren't new to this but I'm trying to understand if their seemingly illogical actions are due to them getting support for trialling this concept??

There could be support in individual DNOs to relieve particular congestion, and Octopus and Axle may have different coverage in those areas, or due to a grid-wide lack of energy but Octopus is already hedged or participating another way...  I don't know.

 

Watch the turn-up and turn-down operations here for a while and you'll get to see/infer all sorts of strange things going on due to constraints, where renewables are generating or not, etc: https://renewables-map.robinhawkes.com/

This is what actually happened.

Amazing how much wind energy we produce, until it drops. Presume our batteries are in others, insignificant on this scale

Yes, along with some very small emergency generators.

 

Gridwatch only shows metered generation, so a lot of domestic PV and micro wind generation is not shown.

 

I joined Axle in the last month via a referral in this thread (thank you)

Since then we've had 4 events paying about £5 each time, therefore so far had about £45 (Note to self - change to a tariff with better export rate)

NICE!
