In my personal case, it was cost of energy due to the Russian invasion of Ukraine triggering a stop on buying cheap gas from them. Infrastructure upgrades are also being done, costing tens of millions per year because the grid can't handle the sudden increase in renewable energy generation and electrification (to ironically move away from dependency on gas). I mean part of me thinks it's a necessary evil because we relied too much on Russian gas in the first place. But that's because we extracted most of our own gas already (https://en.wikipedia.org/wiki/Groningen_gas_field https://en.wikipedia.org/wiki/Groningen_gas_field), which that article lists as one of the factors in the Dutch welfare state being a thing - it and smaller fields out at sea contributed over 400 billion to the Dutch economy since the 1950's.
