I have my last electricity bill, from France, something that's indexed on the "public price" (so it's possible you get extra discount, but I bet it's representative)

Electricity itself is priced at around 0,14 €/kWh (sparing you the 6th significant digits), so roughly $0,16/kWh at current exchange rates and taxes of of 0,034 €/kWh ($0,039/kWh).

Let's round it to up to $0.17/kWh, which is surprisingly close to your number.

The additional taxes are a "flat" fee of 1,8 €/month (2 $/month),

Then there is the registration itself, with sits at about $15 / month. (I can challenge myself to getting bills where the registration and taxes are bigger than the actual current.)

I'm not sure how I would get a nice number in "€/kWh", though ?

I actually checked a recent bill and it's ~USD0.012/kwh (EU0.10), plus taxes and fees (total cost ~USD0.13/kwh or EU0.11) for the actual electricity.

Then there's a USD0.175 fee for "delivery," plus an additional ~50% in taxes and fees for "delivery (total cost ~USD0.26/kwh or EU0.22) for "delivery."

Total cost: USD0.38/kwh or EU0.33

N.B.: The above detail was for the month of June. Prices do fluctuate and I'd expect that electricity prices for July, especially as hot as it's been here, will be more than for June.

>I'm not sure how I would get a nice number in "€/kWh", though ?

I just divided total cost, including taxes and fees (for electricity and for delivery) by the number of kwh used.

That's not very exact as some of the fees do not vary by usage, but I figured it was close enough.
