Recently moved over to Octopus energy on a 12m fixed tariff. Since doing that I've been looking at our energy usage as they provide a nice dashboard for it on their website.
Here's our electricity usage for (Monday) yesterday. Seems we are using just under 1kw per hour. Peaks are after 7pm around 2kw per hour. Seems the house idle power consumption is around 0.6-0.8kw per hour.
I've been thinking about moving to their agile tariff as their website seems to suggest we would save money. Our peak usage is after the national average peak (3pm-6pm) so we wouldn't get stung by the higher prices. I'm just not sure it would work for us as we don't have an EV, so it won't be charging over night, but we will have air con on most nights in this weather and with our idle power usage that would be balancing out our usage throughout the day.
Here's the estimation from Octopus. The top graph is there view of energy usage vs unit price. The bottom is a calculation for our home, based on 24kwh per day. My direct debit is currently £125 on their fixed tariff.
I am also playing with the idea of building my own "power wall" to do a bit of "peak shaving". Something around 2-3kwh. I could then charge the batteries at cheap/free rates and use them during the peak hours. We could also move some of our other loads, washing machine, dishwasher etc. to over night usage.
It 's a tricky one to decide, they seem sure it would save us money but as the unit price fluctuates so much it's difficult to calculate.
Any thoughts?
