All small and medium-sized businesses in Europe are fucked now, but not the American ones, they are sitting pretty.
Some context -- this billing is due to their underlying power company going bankrupt and the billing being moved over to another electric company until Sept 1st.
This bill with a 400% increase is not reflective of increases of overall electric rates across Europe -- which have gone up -- but not in the manner reflected in this particular bill.
These type of eye-popped electric bills for businesses are being seen in the U.K. and Ireland rather than France and Germany because of the unregulated electric provider market in the U.K and Ireland.
