I made the switch to Octopus Energy in early January 2024 and have made a few additional changes since then, with the addition of my solar and battery installations coming online in April and July.
Even the initial switch made some huge savings compared to what I was paying with E-ON over the previous few years.
This first graph shows my electricity demand by year broken down by source (off-peak, peak and solar).
As you can see if anything my usage has gone up for the 2024 year.
This next graph shows total energy usage, including gas for the same set of years (2019-2024).
I then have a breakdown of each usage type by year
These show a substantial shift for peak vs off-peak once the battery system came on line in April.
Gas usage is entirely dependent on the weather conditions, as more gas is used if it is colder and less, or at least only that required for hot water in the warmer months.
Solar production obviously helped a lot in the months where the sun was shining, not so much in the autumn and winter months.
Export only became a ‘thing’ once my system was approved by Octopus as a non MCS accredited installation and I received my SEG tariff in July.
The cost charts however show a huge drop for 2024
The first few months are purely a change from my old E-ON tariff to Intelligent Octopus Go, but once the batteries and solar come online in April there is a huge reduction in electricity costs and likewise with the gas when I switched to the Octopus Tracker Tariff in February.
A further reduction for electricity is seen in July when the East-West arrays come online.
Electricity usage vs cost by year
and the same for gas
The total saving for 2024 vs 2023 are over £4,000, of which only £300 are related to gas.
