Now the heat pump planning permission is approved, I have an installation date. Install will start 22nd July. I need to order some new home batteries. I think I will add another 9.6 kWh. That means we will have 19.2 kWh.
Octopus Agile rates are not very good overnight. Better around lunchtime. I don’t think I will charge overnight tonight. Export will have to wait until it has topped up the battery.
A good solar day. Shame we used £2.24 from the grid last night as the solar was so poor yesterday to top up the batteries. We have exported enough to bring today’s cost down to 54p. Not sure we will break even though.
For the first time I have managed to cover my complete electricity bill. Last year I covered the import, but never the standing charge as well. Some of it was covered by the extremely good plunge pricing over the weekend of the 13th, but even so. Can I cover the gas over the summer months?
I found an issue with my Home Assistant electricity cost coding. I had set the import cost to max. Of course it can go down during plunge pricing. I think I have fixed. I can test it again overnight with my plunge pricing.
I don’t think I have seen Agile prices like this since I have been on this tariff. -7p and -8p amazing. I will not be charging tonight and be discharging in the morning.
I like this new comparison feature in #OctopusWatch v5. I don’t have an #HeatPump, but added it out of interest. Version 5 is not out yet, I am beta testing.
The last seven days have been really good for our electricity costs. £-1.63. A good mix of plunge pricing, battery discharge and solar export. This includes the standing charge.
Ever topical, I have just posted about a night in January when my solar batteries didn't charge fully. Normally this is due to me messing it up. This time was different as they did charge to 80% and I know the SoC level was set correctly.
I had read that batteries can be affected by the cold. It never really gets cold enough in the UK. This night it was -5c and less power was drawn from the grid. It has not done it since, so I put it down to the cold
