My Octopus Agile & Go Tariff comparison / analysis website

As mentioned in the OpenEnergyMonitor Demand Side Response Development thread, using the Agile tariff from Octopus is a great way of shifting usage based on pricing.

With that in mind, the Octopus Agile tariff has really piqued my interest in time of use tariffs using Smart Meters.

Whilst you could grab bits and pieces of historical data from Octopus about ‘Agile’ it was a bit limited. ie it didn’t show all DNO areas and wasn’t complete back to Feb 2018.

So i’ve written a few scripts and pulled all the data in to one place.

  • All 30 minute data from all 14 DNOs going to back to the first day of the Agile tariff (Feb 19th 2018).
  • The data also updates at 5pm each day after Octopus have released their next day’s figures.

I’ve then layered Grafana graphs on top so you can visualise the data yourself on my new website.

Plus, there is a Google Spreadsheet with all the historical data on.

I would be interested in people’s thoughts on the project.

What could be done better?
What else would people like to see in terms of graphs?
Is this stuff useful?

I’m hoping to expand the project into their GO tariff as well as their new Agile Export figures too.

Cheers.

Interesting site. Thanks!

Most interesting to me is to see the period over which the rates are ‘extortionate’ (not really, just very high). It seems to be from 1530 to 1830 each day. So one thing that would be interesting is to see whether that also holds true at other times of the year. e.g. winter.

If it does, or nearly so, then it opens the possibility of an interesting strategy. In our house, all the demand during that peak period is essentially from the kitchen. So a batttery-backup that was able to meet the kitchen load might be interesting - perhaps a UPS?

Hi Dave,

The whole premise of the tariff is that 4pm to 7pm peak pricing which they base on usage and wholesale prices. Thus, they pass the cost on to you.

The data is in half hour periods, is 16:00 on the chart is 16:00 to 16:30, 16:30 is 16:30 to 17:00 etc.

But with solar and/or battery as well as tailored household usage i’m sure you could avoid that period.

The 4pm to 7pm is a daily peak throughout the season on every day. You can see from the year long graph the minimum, average and maximum price each day.

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?

It’s interesting. We’re on an E7 tariff and it’s clear the dip in the half-hour prices pretty much matches the E7 period. The 7p through most of the day is cheaper than our tariff but then we don’t pay it since we have PV.

Our problem with the 1600-1700 period is that that’s when we cook dinner most days and we’re an all-electric household. So it’s a fairly inflexible demand. Definitely too high a power for our solar to provide, and would demand too great a lifestyle change to timeshift or otherwise alter the consumption.

I’d have thought there was an opportunity for somebody to peak-shave that demand period with some kind of storage mechanism, but I suppose it would be competing against people just spinning up CCGT units or even diesel generators, which must be fairly cheap.

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 pricing was as low as 2.1p per unit overnight. Crazy!

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.

Thanks for the link to your website. This is really useful as I was talking to Octopus energy at the Fully Charged Show and I was anticipating having to travel through data to work out what the tariff was like historically. If I switch I’ll use your referral code.

That’s brill, thanks for the feedback.

I got a quote/retweet from the Octopus founder last week who said my site was 'very cool.
High praise indeed eh? LOL

Maybe they’ll nick my ideas and do this themselves?

Thanks for considering using the referral code, will help go towards web hosting fees. :slight_smile:

Nice work @Zarch this is great!
