I’m trying to choose a new SEG outgoing tariff so I can get paid a bit for the electricity I’m not using (no batteries) I would seem there aren’t many companies offering despite it having been around for 6 months or so.

Social energy offer the most at 5.6 pence per unit and then Octopus energy a close second at 5.5 pence for their fixed tariff, they also offer an 'Agile' tariff which is variable depending on the whole sale price. I’m not sure how I would calculate which would be best for me?

I’m also going to get a Solar immersion unit soon. Probably the Solic, in which case I plan to use very little gas during the summer months ( induction Hob ) so I’d like a gas tariff with a very small or no monthly standing charge as I hope to not be using any during the summer months. Is this possible?

Thanks in advance,

Tom.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16667&Focus=282437#Comment_282437 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16667&Focus=282437#Comment_282437 Mon, 27 Jul 2020 10:05:42 +0100 djh
There's a list at https://www.solar-trade.org.uk/seg/ and that also tells you whether you need to use the supplier's supply tariff as well.

There are any number of firms that do supply tariff comparisons, including a discussion of zero standing charges at https://www.moneysavingexpert.com/utilities/electricity-standing-charge/ for example.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16667&Focus=282444#Comment_282444 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16667&Focus=282444#Comment_282444 Mon, 27 Jul 2020 18:54:23 +0100 revor https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16667&Focus=282446#Comment_282446 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16667&Focus=282446#Comment_282446 Tue, 28 Jul 2020 07:38:06 +0100 HoveTom
From researching yesterday afternoon I'm leaning towards Gas and Electric from Octopus Energy as about the cheapest. I can’t find a cheap Gas only supply without a standing charge that compares. Bulb offer the most for your outgoing electric with the option to buy in from elsewhere but again the numbers don’t come out much better than both in and out from Octopus. There is no tie in so you can leave if something better comes along.

I’m still not sure if their Agile or Fixed outgoing will work out better. It’s unclear if you can be on their Agile incoming tariff as well as their Agile outgoing. Agile being pegged to the wholesale market rate for electricity and checked every 30 minutes.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16667&Focus=282448#Comment_282448 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16667&Focus=282448#Comment_282448 Tue, 28 Jul 2020 09:47:34 +0100 WillInAberdeen
Octopus also have a tariff aimed at EV charging which offers four hours of import at 5p every night. So perhaps you could sell them PV at 5.5p during the day and reimport it cheaper overnight, using them as a free 'virtual battery' ! Probably only worthwhile if you do have an EV to charge overnight, but I think it's interesting how the market for these things is starting to develop.

Edit to add: have you done the sums for the solar diverter thingy? If you can export PV for 5.5p and import at night for 5p (or more typically 9-10p on other tariffs) then the solar diverter will save you max 4p per kWh. How many kWh of summertime hot water do you use before it pays for itself? If you can buy gas for less than 5.5p/kWh then isn't that cheaper than diverting your PV?]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16667&Focus=282462#Comment_282462 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16667&Focus=282462#Comment_282462 Wed, 29 Jul 2020 14:39:50 +0100 GreenPaddy Your export payment and night import are the same. Don't see the sense in it.

I do use export minimisation devices frequently, and they can be excellent in many setups (ie. pre SEG and export metering), but don't quite see the benefit for your case.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16667&Focus=282463#Comment_282463 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16667&Focus=282463#Comment_282463 Thu, 30 Jul 2020 11:43:14 +0100 WillInAberdeen https://www.energy-stats.uk/

Those were the pages I dimly remembered being available to help compare the tariffs, not official octopus pages.

Looks like the agile export tariff is worthwhile if you have a home battery and charge it up overnight then re-export during the evening peak period. Otherwise the flat rate 5.5p might suit you better.

(I'm not an octopus customer myself, no connection with any of these folks)]]>
