Here in Ontario, residentially we pay about 0.09 USD per kWh at night and 0.18 USD with demand peak pricing on weekday afternoons. Or if you have flat rate it's about 0.13 USD per kWh. This is considered very expensive by Canadian standards and it's due to our nuclear power program where about 55% of electricity is from nuclear, the rest from a mix of wind/hydro/solar/biofuel and gas. The increased price during the day is due to the need to burn a bit of gas at peak demand. The grid is otherwise nearly carbon neutral, and the long-term plan is to phase out the gas with a mix of wind, nuclear and pumped storage.

We pay less in practice than the rates given above for power, because the government also subsidizes it. But even without that I understand such rates would be relatively cheap in most European countries.

Cries in $0.45/kWh AUD (metro Sydney). Best I've found is $0.37/kWh

Is that the commercial price to the end customer with tax and connection fees, or is it the gross price at the power exchange?

Relative cheap? More like ridiculously cheap.

Existing nuclear power is something to keep around as long as it is safe and needed.

The problem is that new built western nuclear power requires ~18 cents/kWh (Vogtle, FV3, HPC etc.) when running at 100% 24/7 all year around, excluding backup, transmission costs and taxes.

Now try sell that electricity to a home owner with solar PV and maybe a battery and you will get laughed out of the room almost the entire year. A firming new built nuclear plant with ruinously high CAPEX and acceptable OPEX is economic lunacy.

This does not even take into account that new built nuclear power requires ~15-20 years from political decision to working plants.

As soon as new built nuclear power’s costs and timelines are confronted with reality it just does not work out.
