Construction costs are currently skyrocketing

Yes, I have an air-to-water heat pump, but it has its own meter and is completely separate from the mentioned values, I was only referring to household electricity. Photovoltaic power cannot be used for the heat pump with my current setup. The high self-consumption is due to the fact that we have a storage unit, in case that is the background of your question. We bought the house like this. If I had planned it myself, I probably would have done it without storage but used photovoltaic power for the heat pump. Honestly, I hesitated briefly when I typed in the numbers. I also had something like 12.x cents in mind for the feed-in tariff. The €529 compensation is from the bill from Bayernwerk, which I received last week. The kWh are not mentioned in the bill; that is from my records, I simply regularly write down the meter readings.

Who else is currently switching their electricity tariff?
The market price has fallen again recently, but I’ve read several recent articles saying that in the medium to long term it will stay rather high and even get more expensive again.
So I thought I’d better secure a long-term price guarantee now, even if it’s at a higher but calculable level.
Besides, I found a provider who still only offers a 1-month cancellation period (Octopus).
I’m not too happy about the British parent origin, but at least it’s an eco tariff.
144 EUR basic price (relatively high), and just over 40 cents/kWh.
Berliner Stadtwerke unfortunately won’t budge from their 52.9 cents/kWh. Luckily I can also cancel with 1 month’s notice.
If the price for long-term contracts drops again in summer, I can just cancel again.
What are you up to?

Where can the basic supply prices actually be found?
