The Swedish power companies use a similar tariff. The basic charge is based only on the fuse size. It doesn't matter if you are a commercial customer or a consumer.
3x16A (or 1x35A) comes at $30 a year (But you pay an extra $.01 per kWh)
3x25A comes at $250 per year, and 3x50A at $600 per year
(If you live in the countryside, it of course becomes much more expensive.)
Usually you pay some $.08 per kWh. (Haven't checked lately since I have an unmetered supply.)
