My Octopus Energy Agile & GO Tariff analysis website

[jtp10000]

Just had a look at the most recent data.

Interesting, overnight last night Agile had a low of 3.11p per unit. It was no higher than 6p from midnight through to 6am, then 7p through the most of today.

I think alongside a small battery to get you over the 4pm to 7pm (20p to 23p per unit today) period if solar can't cover it, this could be a decent option for many people?

Its just about finding the right combo for your circumstances that will allow the best savings (tariff, solar, battery, ev, immersion, usage habits!)

Interesting point. Of course if you approach like this it totally changes the maths of getting a battery.

I've added a simple single page showing what the Go tariff looks like in graph form as well as the current "out of the 5p four hour slot" pricing across the UK.

Electricity was as low at 2.1p overnight on Agile.....

Hi all,

I'm pleased to announce an update to my little home-brew website; Go versus Agile

This was actually a feature request from a user so I was happy to oblige.

There are two new graphs for each of the 14 UK regions.

1. Go versus Agile (00:30 to 04:30 only) for the last 365 days
2. Last 7 days of full daily pricing from both tariffs

https://www.energy-stats.uk/octopus-go-versus-agile/

I think if you have an EV then Go seems to win hands down with its fixed 5p for 4 hours each and every day.

If you have Solar PV and/or maybe a battery that can get you over the 4pm to 7pm period then I think Agile could well be the cheaper option?

But everyone has different usage patterns and configurations, so ultimately the decision is up to you.

These 'time of use' tariffs in conjunction with smart meters are surely the future of electricity provision?

Hope you are finding this data useful?  Please let me know your thoughts etc.

Hoping to add some more features in the coming weeks.  Next up I want to look at the new Outgoing / Export tariffs.

Cheers.

This data is just what those Solar PV owners have been waiting for.

Discussion points and my notes/thoughts for Octopus Outgoing Export Tariffs

- Their fixed 5.5p per kWh fixed outgoing is a 2.2% increase over current Feed in Tariff (FIT) based 5.38p.

- These Outgoing tariffs only replace the 'export' element of the FIT.  Your generation payments will still come from your registered FIT supplier.

- Both Fixed and Agile Outgoing are "actual" export rather than "deemed" 50% as per FIT.

- You are likely better to stay put on deemed 50% if your export less than 50% of what you generate. ie, if you have immersion diversion, EV or other high daytime usage.

- If you export more than 50% of what you generate the maths suggest you'd be better off on an 'actual' export tariff. The could well be the case with larger Solar installs.

- Octopus add credit to your bill each day for your exports. Assuming you spend more on "inbound" energy than you earn on "outbound" they'll aim to set direct debits at a level consistent with the estimated annual net amount. If you're in credit you can withdraw at will online. (From Octopus CEO)

- In comparison current FIT payments are usually every 3 months.

- You need to be on an Octopus import tariff to have one of their export tariffs.

- It will be very interesting to see the Agile Outgoing price through the winter months.  The outgoing tariffs only started on 19th May 2019, so we have little historical data to analyse.

- Whilst its easy to claim 11p per unit and above between 4pm and 7pm during the summer because of late sunset times, its going to be impossible through the winter months with 4pm sunsets.

- Moving to Octopus requires a 12 month commitment for FIT payments.  This is across the board, you can only move FIT supplier once a year.

- But this does not apply to 'export' supplier.  You can move when you want.  Plus, you can freely move between Fixed and Agile Outgoing / Export plans once with Octopus.

- So maybe there is opportunity to crunch the numbers to see if Fixed or Agile are better suited at different times of the year?

- Will the Octopus Fixed Outgoing tariff increase with inflation as per the current FIT rewards?

- The FAQ says there is nothing stopping you charging a battery using Solar during the day for free then selling back that energy between 4pm and 7pm for 11p+.

Your analysis is confusing me.

First scenario - if your export more than 50% of what you generate - surely it is better to be paid per unit of export rather than just for 50%

Second scenario - If you use less than 50% of want what you generate - this is the same as the first scenario.  If you use less than 50%, you export more that 50%.

Or is my brain not working?

Also, does the 5.5p payment also apply to those on the older 3p plus inflation export tariff?

[Zarch]

Thanks John.  I've updated the text.

I knew what I wanted to say, just got a little confused typing it..... 

Hope the update is a bit clearer?

With regard the older export tariffs, I've contacted Octopus to find out..... will let you know.

April 2010 to 30 July 2012: 3.82p
On or after 1 August 2012: 5.38p

Zach
It makes sense now.

John,

I asked Octopus the following..... hope this helps.

"Another question about Outgoing tariffs. There are two FIT export tariffs dependant on install date. 

April 2010 to 30 July 2012: 3.82p
On or after 1 August 2012: 5.38p

Can pre-July 2012 installs join Outgoing? Do they get 5.5p per kWh / Agile pricing?"

Their reply was:

Ok, those are the FiT rates you’ve quoted there. Outgoing has just the two rates. You can switch to Outgoing (either 5.5 or Agile version) irrespective of which FiT rate you have. Hope that helps - but do drop us a DM / message if you have any questions & we can go through everything.

[JohnS]

Thanks.
It looks a great deal for pre 2012 installs

More crazy Agile prices overnight.  Down as low at 1.26p per unit and below 8p through most of tomorrow.

Website update:

As Octopus Energy outgoing tariff (ie the FIT export replacement) tariff is now 2 months old i'm now showing 60 days data from the Agile version of the tariff.

Hopefully more info for those considering moving away from FIT export payments or for new installs needing someone to take their excess generation.

Full details over on the site.  https://www.energy-stats.uk

Interesting to see that the overnight tariff is rarely near the 5p Octopus Go Level.
It would be great to do a calc to see how cheap a house battery would need to be to make a 5 year payback on Agility. The simple approach might be a battery that would only need to bridge those expensive 2.5 hours in the evening and then the rest of the time you are on 7p.kwh ish. I should try. I can't believe it is that far off before it is a no brainer.
BUT then of course how quickly will the prices start evening out if lots of people get batteries, killing your 5 year payback. Also the utilities would be mad, after all the SMETS installations & data, to not start providing substantial incentives that discourage people charging their cars at 6pm.

[Philip R]

jtp,
As more smets meter data is analysed, the power companies will be able to dis incentivise those whom charge their cars at evening peak times. i.e. Switch them off using the meter internal contactor. In my previous employment, the factory where I worked, had some very large loads which if turned on or used at the wrong time, would lead to the business being charged a punitive rate for electricity for the next 3 months. A very strong incentive. That is why the diesel generators were fired up. Expensive, but cheaper than the punitive tariff.

As we are about to move into the new house I have just switched to Octopus from SSE and once on I believe the Smart Meter follows, been interesting reading the above (the bits I understood!) but what I want to try to do is progress to Agile (if possible) and program my Powerwall 2 to charge up (if needed) at certain cheap times.

At the moment I am just getting to grips with the PV and Tesla setup, I do know that in the last week 98% of the power used in the house is 'Self Generated', I know we aren't in yet but the ASHP is working along with the UFH and generally using 200 w which seems good. I know things will change once the Winter comes along so that's why I'm looking to get cheap rate charging on the battery and from what I can see above its a good possibility.

Still watching with interest!
