@ronin92 I have only participated in 2 as my application took some time to process; a 1 hour and latterly, a 2 hour in duration. I use little energy during that time slot as cooking / washing/ drying etc. is done in the mornings but, I have still saved about £5. I will admit to not using the grid at all during the time slots as the Powerwall took over. I have also been given a date for our ASHP installation now, Feb. 8th and onwards. No news from Octopus Energy on special tariffs yet though.
Toodles, 76 years young and hoping to see 100 and make some ROI on my renewable energy investment!
I think participation in these also depends on the auction offers by suppliers. E.On offered me participation in tonight's event (Monday) but I have heard nothing about tomorrow's (Tuesday) so perhaps they asked for too much?
HUGO Winter Cashback 4 Alert. Yes another event already! Tuesday 24 January 430pm to 6pm - Payments 5.46 per kWh saved. Turn on Event button in SETTINGS to participate.
From tweet by EnAppSys, the price curve for tonight (Tuesday):-
At the moment the wholesale electricity price shown on the grid.iamkate.com website is £120 / MWh, Octopus is offering Agile user's the same at £330.30 / MWh, so I wonder which power generating company is so kindly offering to balance the grid at the bargain price of £6000 / MWh. 🙄
These companies should be named and shamed, and made to justify their prices. 😡

The graph looks like the prices the suppliers like ovo, octopus etc bid for their customers to cut their electricity under the Demand Scheme hence for example the £3 bid by OVO at the low end.
This isn't a graph of generators? Unless i am mistaken
Hence the title of the graph?
Each supplier had to put in a bid for a number of kWh and price.
Some companies e.g. Hugo and Octopus are offering us more to cut electricity in the current session than the 1 hour slot on Monday.
Others like ovo are offering the same £3 per kWh as yesterday

You may indeed be correct, but if National Grid (who set the price) are offering this kind of money to the electricity suppliers, and are saving money by doing so, then what price are the electricity generators charging?
The wholesale electricity price is the price offered by the marginal generator which is usually from gas in UK. While that is the price of the marginal kWh, it does not indicate how much more is available at that price. That the DFS has been invoked indicates that NG ESO thinks spare generation capacity is too tight for comfort (presumably because gas generation is already fully committed?) and they deem a demand reduction to be better/more feasible than invoking other sources of generation.
The DFS price curve shows how much generators want to "bribe" their customers with to reduce consumption to meet the DFS call. Guess what? We require a lot more to move us than the average utility company. I can already hear the cries of "Greedy consumers!" (not). The auction for DFS response is based on "pay by bid" rather than "pay on clear". The accepted bids are the cheapest required to meet the demand reduction asked for under DFS. There may have been companies that asked for more but they don't appear on the chart. The companies that bid lower offered your cooperation more cheaply than those that bid higher - so yes, different consumers are being paid differently for the same reduction.
You can see what ESO asked for yesterday and today, what companies responded with and the the individual accepted bids for each half-hourly service period (see here; DFS utilisation report). I note my utility had accepted by ESO, multiple tranches priced between £3-£6/kWh. It may also explain why my utility only invited me 2 hours before the event - I think they must have been tracking uptake to determine when they had just enough customers accepting to meet their committed reduction and I typically have rather low usage over that period.
P.S. DFS cost around £700K for each half-hour today, ~400+K yesterday.
