Basically it means they will read your smart meter every 30 minutes.   it will allow them to offer tariffs based on usage of electric during the day.  it shouldn't affect you if you stay on a standard tariff, you would still only pay the same amount.

I am with Octopus on the Agile tariff.    They charge me a price based on the wholesale electric price at the time - when they read the meter they get my exact usage for those 30 minutes.

For example,  for the electric I use between 12.30pm and 1pm I will be charged 14p per kWh and then between 1pm and 1.30pm I will be charged 15p per kWh.     This means I will be saving against the current standard tariff ( I think that is about 23/24p per kWh).   Therefore I would do my washing while it is cheap etc.

However, at 4pm (peak time) more people need electric as they get home from work and my cost will be 28p per kWh and between 6.30pm to 7pm it will be 34p per kWh.

As you can see, the price is more expensive from 4pm to 7pm and then it drops again.    As I am at home, I make sure that I cook my tea at 3pm or 7pm and it saves me money.

It's like everything, a bit of work saves money.      I have an app that tells me the difference between what I would have paid on the standard tariff and the agile tariff for my exact usage.     In the last 30 days I have paid £40.96 and the standard tariff would have cost me £55 so in my eyes it is worth shifting the time that I use electric and save the £15.

Hope this helps.

Sadly inaccurate, they don’t read you meter every 30 mins, they get historical 30 minute readings usually once a day.

Hmm. Just been onto my app (not EON) and the half hour reading from 1200 is already there. If I look again in a bit, the 1230 one will likely be there. And so on.

EDIT - 10 mins later the 1230 reading is now there.

Who is you supplier? You don’t have an Octopus mini per chance

Nope. My supplier is Fuse, reading my SMETS 1 meter, all readings from the Fuse app. Half hour readings are always through no more than an hour after the half hour has finished.

Aaaah , fuse only has c50000 customers so they can cope with it

Maybe I am wrong but I think you used to have the option of allowing your meter to report half-hourly data or not.  Perhaps the email means that Eon have opted you in, despite any previous choice you made?

Hi, the email from Eon has button to click to opt in to the 30 minute settlement, so Im not on it yet. Got no trust in utility companies so asked you fine people.

From the e-mail

Your clever smart meter sends us your meter readings and it can also send your electricity usage data.

How we’ll use your smart data.

From 28 August, we’ll start collecting your electricity data every 30 minutes - this is for half-hourly data settlement. If you’ve already agreed to us collecting your data every 30 minutes we’ll now also use it for half-hourly data settlement.

On a time of use tariff? We’re already collecting your data half-hourly and using it for settlement (a condition of your tariff) - we’ll now keep doing this even when your tariff ends.

You don’t need to do anything

We’ll switch you to half-hourly data settlement automatically.

We keep your data safe and won’t use it for other purposes without your permission. Visit our privacy policy to learn more.

So, what is half-hourly settlement?

It’s a new system introduced by Ofgem to improve how electricity is bought and sold. Currently, smart electricity data for settlement is collected monthly which means we know how much energy has been used but not when it’s used - moving to half-hourly settlement tells us when you use your electricity.

Half-hourly data for settlement will help us to:

• ✓ ͏‌ Reduce carbon impact
• ✓ ͏‌ Lower the cost of electricity for customers
• ✓ ͏‌ Make sure our electricity grid is future fit
• ✓ ͏‌ Rely more on renewable energy
• ✓ ͏‌ Support the grid to reach net zero by 2035
• ✓ ͏‌ Drive the UK towards net zero by 2050

Find out all there is to know about half-hourly data for settlement.

Want to opt out of half-hourly data for settlement? You could choose to opt into daily data for settlement instead - just head here to update your preference.

Remember, our time of use tariffs require half-hourly data for settlement so you can only opt out when your tariff ends.

Any way we can help, we will.

I am just going by what they are specifically saying.    Either they are wrong with what they have said or they are actually going to start collecting it every 30 minutes.    It most certainly is technically possible as per Fuse already doing it.

Hi, got an email from Eon saying they are introducing 'half hourly data settlement'. Anybody know about this change? seems to be industry wide. The only thing i care about is will this cost more for me. Thanks.

Anybody know about this change?  Yes.

Theres a summary from one industry sector trade body here - but plenty of info on Ofgem pages etc

https://www.energy-uk.org.uk/publications/euk-explains-market-wide-half-hourly-settlement/

will this cost more for me ? Right now no, the hope is not, that it might save in some future years.

But make no mistake it will not be free for suppliers to modify their systems to collect and collate 29m homes worth - once roll out complete - of smart meter data - in order to achieve the goal.

And it's not the only change Ofgem are allowing suppliers to support HHS. Like to DAPF that Ofgem have already been implementing as part of this process.

And if you think DAPF was only added over some folks paranoia - read the above link - and particularly the line about new innovative .... all customers - and key - influencing how and when use energy.  

This is an industry led initiative - not a regulator led one. And after c30 supplier failures and SoLR costs - I really dont trust Ofgem to have worked out the pros and the cons properly, just as they failed with switch to save for millions of households - and then imposed c£100 SoLR on us all.

Will I be giving permission - No

Certainly not without reading more about what it means.

They claim it's essential for likes of all  TOU including E7 and E10 under HHS - it certainly isnt for my billing.

I am not sure if they will really be reading 33m plus smart meters every half hour - or whether they will just be accessing 1/2 hourly resolution data - in order to collate and settle after the event.

I have certainly read posts suggesting that the time larger suppliers read different peoples meters already changes.

For instance - suppliers under the orginal DAPF - had 3 data time resolution options for billing

monthly data

daily data - the default - opt out of daily possible to go monthly only

half hourly - opt in only - they needed to ask the user for permission to access

So it could just be they intend to actually read say one days set of 48 half hourly readings.

Which for many - suppliers will certainly have received no user permission to do so.

Ofgem have been dancing around this issue for a few years now, but by the time MHHS is fully implemented they will not need customer permission to retrieve HH data for settlement purposes.

To be fair they have already swapped half hour from opt in to opt out on switching - meters or suppliers iirc - I'd have to find the change again - it wasn't exactly published widely.

Yes, that was a while ago, but ultimately the ability to opt out will have to go as well, perhaps with the caveat that it can only be used for settlement without an opt-in.

Also those who have not switched since having previously not opted in will have to be addressed.
