Economy 7 times ?

Hi ​@shetland ,

The closest match I can think of would be Standard Economy & Heating Load. I seem to recall you’re up in the Scottish Highlands and Islands based on previous discussions so if you’re in the Shetland Islands, this might be what you’re on.

The other one that comes to mind would be THTC. This one is definitely weather linked because during bad weather you’re given additional heating hours and during good weather you’re given less.

Worth noting that support for both of the above is ending soon.

I don’t recall OVO offering Economy 8, but I can try to ask ​@Chris_OVO if he knows anything. Could you show us your meter again please?

Hey ​@shetland,

I just wanted to clarify that, as far as I know, we don’t currently offer an Economy 8 plan, as ​@Blastoise186 pointed out. I’ve looked through our internal resources and found details only for Economy 7 and Economy 10. To make sure you have the best information, I’ve also asked one of our heating specialists for any additional options that might be available. I’ll keep you posted!

If you’re just asking for the times in general I found the following on   “8 hours of cheaper electricity in any 24 hours for approved heating and hot water systems. These are set at 00.00-04.00 and 12.00-16.00” on Jersey electricity’s website.

Hey ​@shetland & ​@Blastoise186,

Apologies for the back to back messages but i’ve had the information back quicker than I anticipated. 

“Economy 8, also known as domestic economy, is a Scottish version of Economy 7. If you are in the MPAN 17 or 18 area, then you will be on Economy 8. Your times vary depending on British Summer Time (BST), so please adjust accordingly.​

MPAN 17 23.30-07.30 GMT
MPAN 18 23.00-07.30 GMT”

I hope this helps!

MPAN 17 here.

Thanks for trying, but I have 3 off peak periods a day, 

For example, an old example of actual times when it was E7 before getting a smart meter:

1.08am on
3.08am off

7.08am on
9.08am off

2.08pm on
5.08pm off

Now with E8 I get an extra hour, and the times are different.
  ( Nice thing about the new plan is the entire house is on off peak, and not just the heating ! )
  ( Bad thing about the new plan, can’t move to another plan, or supplier ! )

They changed last around winter time, not sure if it was BST related or not.

From the OVO account details:

---
Plan name

Simpler Energy - Region Specific

Copy of chat transcript with OVO:

---
 16 Apr 2025 7:47:06 AM - Customer: Is that an E7, E8, E9, or E10 tariff as we have storage heaters.

16 Apr 2025 7:49:03 AM - Agent: As you live in a Load Management area the tariff will be a variable tariff that will be specific to where you live so it will not be economy 7 8 9 10

16 Apr 2025 7:50:10 AM - Customer: Do you have the times it goes from peak to off peak/etc ?

16 Apr 2025 7:50:54 AM - Agent: The times are 00:00-02:00 06:00-08:00 13:00-16:00 21:00-22:00"

I dunno what you call 8 hours then, if not Economy 8 !

OVO insist the times are:

---
Your Off Peak rates kick in between 22.30 and 06.30 You Peak usage is between 6.30 and 22.30.
---

I’ve tried telling them I get 8 hours, split between 3 zones, but they insist this is my times.

Is this a new thing, no more 3 split times ?

I assume since the hour went on, the new times will be just 1 hour ahead, but of course, they might not be !

Old times:    New Times:

00.08 on    01.08 ???
02.08 off    03.08 ???

06.08 on    07.08 ???
08.08 off    09.08 ???

13.08 on    14.08 ???
16.08 off    17.08 ???

21.08 on    22.08 ???
22.08 off    23.08 ???

This time, unless someone has an accurate answer, I’ll just check those times myself, and report back, and hopefully save someone else the bother when they want to know the answer too !

But it doesn’t answer the question, when will they change next.

This will hopefully solve that problem with a CT clamp on the storage heater circuit.

​@Chris_OVO That doesn’t explain ​@shetland’s three offpeak periods. He knows there are three (by virtue of watching the meter with stopwatch in hand). There may be special arrangements up there - Shetland is the ultimate outlier, after all, way off the National Grid. Perhaps Energy Shetland would have a better idea - they may even still have some sort of load balancing in place, although I don’t know how that would work with an OVO-controlled smart meter. 

Hey ​@shetland,

I’ll send you a private message to see if I can get you some answers! 

I’m sorry we seemed to fall out of sync yesterday, so my carefully-drafted contribution eventually made it to the thread some hours after everyone else’s input had rendered it more or less obsolete.

Well, yes - it seems that my concept of ‘three’ differs from ​@shetland‘s. His own enumeration of his offpeak periods, which happily coincide with ​@Chris_OVO’s official ones bar a time-zone change or two, sadly doesn’t quite match with “Note, this [...] comes with 3 periods of off peak” from his OP. Now I’m not quite sure which of us is the schizophrenic.
