Octopus Energy Saving Sessions

[Stranger Dings]

Does anyone know how the Octopus ”Power Hour” energy saving sessions are actually calculated?

I’ve taken part in all of them, but the results just seem totally random.

I’ve had sessions where we’ve switched off as much as we can and gone out, only to be told that we didn’t manage to save anything.

Some sessions, we’ve made very small savings, Including one where virtually everything was switched off and the whole family was in another country.

One session I forgot it was happening despite signing up, only to be told I’d managed to save 93% of my normal usage and be credited with over £16 off!

I’ll continue to sign up for them and don’t really do it expecting to save much as we are already quite energy efficient. It all just seems so random.

Probably not, the delivery rate has been below service requirements for each one to date by some chunky percentage.

So likely usual £2.25/1,800 OctoPoints/kWh.

Not exactly clear what they are testing here with the third Tuesday in a row.

 

[Pink Duck]

Confirmed as £2.25 / kWh saved. 297 MW and 300 MW procured respectively of 350 MW requested.

Just be notified by Home Assistant that I've been auto enrolled

Also testing out a new automation to charge my GivEnergy battery for a period before the session starts to ensure there's enough juice to export so if that all works out I'll share that

Using Zilla's automation for accepting saving sessions worked like a charm. again.

Now, I made my own simple automation to change my Growatt inverter settings to allow export... will test today

I feel your pain
charging couple of kwh @ 30p to discharge 3 kwh at £ 2.25

Ok, I’m not saying I’m right, but see what you think of this logic.

Assuming you will have enough in the battery to last the whole savings session. Would it not be better to run out after and then use exactly the right amount of peak to 23:30 than to top up before with an unknown amount and perhaps “over buy”?

Of course that first point may not be true for you.

This is what I do... but... you have no Blackout reserve should the worst happen.

Bit embarrassing, but hey ho...

I'm down to 5% battery on two Powerwalls right now, with nearly two hours to go...

Edit: in fact, I'm boosting it to 10% backup power, at peak rate, to give me some slack. It'll cost me 40p (having earned £11.25 in the savings session)

And In case you will not have enough to last full discharge session?

wife works from home - we had like 3 washing + drying sessions.. my battery was empty by 9 pm anyway

Yeah... my Wife was cooking today, but in amongst it all was Lemon Drizzle Cakes.

So... God Damn it... trapped.

 

[phil4]

If you wouldn’t last the entire session discharging, I agree, top up before.

On the backup part, power cuts are rare here.

Agile goes negative tonight. Hoping for “Free electricity when the grid is greenest.”

Or maybe they’re just waiting for Xmas day.

Very low carbon intensity week. Nice.

Negative wholesale electricity prices at the moment.
It’s been a while since I’ve seen that!

Nice for the wind farms providing 58% of our load. £73/MWh guaranteed sell into a market that is trading at negative £31!
Thats an attractive RoI.

 

[ACarneiro]

Well, good for them. I have no problem with entrepreneurs reaping the benefit of their investment

I'm on Intelligent Octopus and have no free electricity options.

Shame, I'd be happy to start charging...

If only we had more freeloaders like you...
