Construction costs are currently skyrocketing

Today I spoke with the municipal utilities about water. If I apply for the connection <5m this year, it costs €1730 all in. If in 2023 then ~€3300.

By the way, electricity. How is it when the electricity contract (31ct/kwh) with the 3 big letters expires on 30.11.22 and I have a price guarantee until 31.12.22 and tacitly renew it. The contract is automatically extended by 1 year without cancellation. According to my understanding, the provider must adhere to the price until 31.12.23, right?

Building a photovoltaic system as a hedge would have already been the right way... anyone trading commodity contracts with rollovers privately hopefully is more deeply involved in the business; most make losses doing that.
'Contango' WTI oil situation 2020 as an example.

But that is also a good example that the evil speculator is only boiling water. At some point, they have to sell to someone who actually takes the good at that price, be it oil, gas, electricity, stocks...
I believe the gas situation for winter is quite well under control. Storages are overfull, LNG terminals are coming into operation, and tankers are waiting off the coast to sell. If no pipelines to Norway blow up here, Russia will probably be completely replaced this winter. I never would have expected that in February, and despite all the criticism of the government's back-and-forth bungling, that is truly an achievement that should be appreciated.

How is it when the electricity contract (31ct/kwh) with the big three letters expires on 30.11.22 but I have a price guarantee until 31.12.22 and tacitly extend it.

However you managed to get this situation... Then you extend and have a price guarantee until the end of 2022. So for 11 months you get a new and probably significantly higher price.

Although I can say that the 3 big letters are very accommodating and also very fair with existing contracts (increase of 2 cents per kWh)

Apropos electricity. What happens when the electricity contract (31ct/kwh) with the 3 big letters expires on 30.11.22 but I have a price guarantee until 31.12.22 and tacitly renew it. The contract is automatically extended by 1 year without cancellation. As I understand it, the provider must stick to the price until 31.12.23, right?

No, when the price guarantee expires, they are allowed to raise prices, but as far as I know, you then get a special right of termination.
