EDF have changed Economy 7 times

dealyboy

Thanks Patty,

The standard MTCs (MTSC) I'm used to are in this table ...



... mine was 808 (until this month) for 00:00-07:00 and I believe @Swipe had 811 (IIRC) for 00:30-07:30. Very occasionally I've seen someone mention one outside these ranges, but I think they have either taken over a business premises or have been in a region that has 'specials' for their customers.

What is your area/distributor id, bottom left of your supply no. (2 digits)?

For your interest here's a pic - I could set the 2 (non hard wired) NSH to the current incorrect tarriff times but dont think my elderly heaters would take in enough energy,  with the broken up hours, to give out any meaningful heat.
If chasing up EDF and threatening the Ombudsman doesnt get a speedy resolution its an option to consider if it gets colder.

Perversely heating them more than once a day might mean they take in and give out more energy than they would in a single charge - expecially if on old ones like mine - the input not set to absolute maximum.

Do your heaters always take a charge for the full 7 hours - mine never do - and even with 10 hours available - only typically take 3-4 hours max daily - even when sub zero outside - but there het 3x per day - and I run a colder house than most (17C max LR).

On E7 older heaters like mine go to set core temp likely only once per day - my instruction tells me to set to max - they never are - so they migth take a full 7 hours in that case - and then cool down - depending on any variable output vent control etc not used in my case - cool down over 17+ hours to next charge.

On my E10 - my heaters go to set temperature - lower in my case deliberately to cut costs - 3 times per day - lower peak temp than with e7 say to give same total energy in and out - but reaches that lower set temperature 3 times a day.

I think it helps smooth the room temps over the day - at least in the simplest case of no variable output control use.

Thankyou Scot,
Telephonic signal isnt great here in deepest Devon and the meter occasionally doesnt communicate but when my bills come they are accurate for the meter readings.

Thankyou everyone. Lots of interesting things to think about and the more conversant I am with detail the better i can qizz EDF .
DealyBoy, my supply numbers are 3 across the top line and a13 digit number underneath. No 4 digit numbers anywhere.

Ildhund in a previous comment worked out from tables that my SSC was 0813

... errr ... It looks like the SSC is 0183 based on the Profile Class (02), the Meter Timeswitch Class (038) and the Line Loss Factor Class (30). 

  Extract from Elexon's Market Domain Data table
  'Valid_MTC_LLFC_SSC_PC_Combination_367'

  These combinations vary with suppliers and DNOs,
  so a table like @dealyboy's will probably only apply
  for a specific supplier in a specific GSP region.
  I don't think offpeak timings are dictated by DNOs;
  I understand it's a negotiation between supplier
  and DNO that lays them down.

OK thanks  ... so the OP in Devon will be in the South West area where 'all meters have different settings' and have an area/distributor id of 22.

... and referring to your earlier post

the Night TPR (0183) 01148 gives 00:15-07:15 GMT. The meter ALCS calendar with a 15 minute offset, activation synchronized with the register/rate switch, should give the correct day/night readings and NSH operation.experienced.

Maybe EDF needs to send a command to re-set the meter tariff TPR.

Have you confirmed the billing matches the smart meter times/rates? We use TOU tariffs that are billed correctly but the smart meter never seems to know that and just shows £ usage based on the standard variable tariff.

That's just what @Swipe said a couple of days ago:

That's a simple 5 port smart meter with ALCS (off peak switching). A simple fix for EDF to send the correct tariff times to match the 00:30-07:30 GMT ALCS schedule. Not sure why they are giving you the run around. Back to them now with a threat to go to the ombudsman if not fixed by the end of the week since your complaint has been open since August.

I'd only add that the nominal offpeak times in this case are allegedly 00:15-07:15 (GMT). The only evidence we have of the start time is @pattymac33's observation; it's likely that her 01:30 (BST) is in fact 01:15 plus her meter's randomized offset. This offset (always a delay) is unique to each meter, and it applies to both the tariff switching table and the ALCS calendar, so EDF should be asked to ensure both are set to the nominal timings. 

[The offset doesn't apply to half-hour (Hh) bucket times, which is why it's never possible to get offpeak register readings to tally precisely with the ostensible equivalent Hh quantities. Those on ToU tariffs take note!]

Hi Michaels, 
The meter itself, on its scroll through settings, tells me what the active tariff is at the moment of looking. So checking when off peak is on is simple.
My bills match the usage as shown on the meter for standard and off peak KWh used.
