Octopus Energy Comparison and Octopus Agile Calculator

Octopus Energy Comparison

This web app collects the data automatically each day from Octopus Energy using its public API. It then uses that data to perform calculations based on the data you add to the form. Rubbish in, rubbish out.

Tracker data for this script is now collected automatically from Octopus. And should be updated each day before 7am. I have also started collecting the data for the Gas Tracker tariff, also exceptional value.

See the wholesale prices for Electricity since 1st Feb 2020 and wholesale prices for gas since 5th March 2020.

The default values used in this table below are my consumption for the year to 20th January 2021: I have consumed 6260 kWh in the year, and my podpoint charger reports that I have used 1500 kWh of that for charging my electric car.

Fridge and Freezer run as they require day and night. Clothes washing 8am or after 7pm. Dehumidifier to dry clothes runs when needed in winter 10pm-7am

Working from home computers run mostly 7am to 12 and 7pm to 9pm. This website runs on an Rpi 24/7 and consumes 8 watts. Security systems and cameras run 24/7 and consume 15 watts.

Update 24th Feb. We have now got our smart meters fitted by Octopus and have moved to Agile. Over the past month we saw a brief period of higher energy prices as cold weather moved down over Europe. However as the mild westerlies have returned wind generation has gone up and energy consumption has gone down. Last night I recharged my car at under 3p/kWh. We avoid using most electricity between 4pm and 7pm and most of our daytime consumption is in the rest of the daytime period. Today that will avaerage just under 10p /kWh. I am very happy with that!

Octopus Agile rates are updated every day at 5pm on this website
