Is there some mistake?

I am a model engineering enthusiast and because of this I have a metal turning lathe which is three phase in my garage, so I need a three-phase supply.

Have I understood correctly that from €55.9, the meter rate is to go up to €420?

I am a pensioner (supporting a non-pensioned wife) and have been awarded the full cost of living increase of €212, for which I am grateful.

I need it for the steep cost of living increase in everything which is the same for everyone including pensioners. The increase is still €152 short of the meter charge.

Has the meter rate gone up because of the increase in fuel costs? How does a meter (service charge) connect to fuel increases?

Can someone who worked out these figures enlighten me? I am sure there is some mistake because nothing on earth increases by 650 per cent overnight. Can someone assure me that there was a mistake somewhere and the true increase will be shown?
