Octopus export tariff (non-MCS)

[Wil]

Apologies for a new topic on this - I did search but couldn’t find previous topics- I’m trying to sign up for Octopus’ non-MCS export route. I’ve provided my DNO letter and Building Reg cert covering the install. They now want the £250 ‘with no guarantees’.

 

Anyone that’s been through it know what happens next? Are there any further loopholes/ reasons for them to reject?

 

TIA!

I had the same Email. Also offered the grand total of 4p for export, as I have no signal to smart meter, so it's dumb. So 6500kWh export, before break even, a complete waste of time.

 

Instead I just push it in to my own battery, excess goes to hot water or heat pump. Yesterday used 99.1% of all PV generated.

Yep I do that already, but I have the capability to add significantly more PV (and DNO agreement to export 11.68kW) so I could be making money back on the days when I’ve filled the hot water tank, batteries and car.

 

I can get 35kWh on a decent day with my currently 5kWp array. I have a functional smart meter so hoping for at least 15p/kWh. I already have the export MPAN from the DNO, just need octopus to accept it! 

 

I’m sure I read of others here who had used the non-MCS route?

exporting without a battery you are going to be stuck with low rates 

lookat octopus FLUX

 you can fill up your own battery between 2 and5 in morning for 4.42p  and sell it back to them later inthe day between 16-1900 hrs for 27p--even in wnter when your panels are not doing much it could still be a big winner

you need to check your postcode cos the rates are different for other parts of contry 

 I would not have gone for PV without a battery --thats where you can start to make the money back

We have

• 3.84kW peak on the roof.
• Main focus: self consumption. 
• All solar directed to a 14kWh capacity water heater.

Here's my export for this year so far  (£11.88 in total)

[Wil]

I have batteries (although set not to export due to the 3.68kW per phase limit) and on Octopus Go so 7p overnight 11.30 to 5.30am and 23p the rest of the time. Getting a blended rate of approx 16p so far this year.

 

in winter with the HPs I rarely get past lunchtime before the batteries are flat. Let alone 4-7 to export what’s left.

I charge EV, battery and dishwashers/ washing machines overnight to maximise night use and can avoid 90% of daytime usage which means I dump solar into hot water tank and anything else. I currently export almost nothing but I could heat the HW to 65 instead of maxing out the immersion and actually concentrate on some export.

I think with the Octopus non MCS option you pay £250 to join but get back £100 if they reject you??

 

How lucrative it is depends on your own circumstances but we'll hopefully be around net £0 over the year for eleccy, so well worth it for us and no batteries needed:)

Yes it’s £150 back if they reject you, so only £100 lost, but just wondering what hoops I need to go through having had all the paperwork submitted to them already.

I submitted mine and, beyond receipt for the documentation,   heard nothing (2022) . A  good while  later ( 6 months?) during a random quick look at my Octopus account I found that I'm on Flexible Octopus.

I expect I missed an email

I’ll answer my own question- i got an email a day later saying i was now on octopus outgoing… now have to adjust my automations to not consume every last drop.

 

15p/export vs my night rate of 7.5p means worthwhile exporting once the battery and the hot water are complete.

Don't you want to export everything  you can and charge the battery and hot water overnight on the 7.5p rate....assuming your battery and DHW tank are large enough for a days use??

[Wil]

I can’t export my battery sadly as it was set up prior to any export agreement. I let the HW charge from the ASHP whenever it needs but have been dumping solar into it until recently. You make a good point though- I could export the batteries to 30% (in case the HPs kick in during hte day) and only export the solar.
