Nuclear energy key to decarbonising Europe, says EESC

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.

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

Consumer price of the energy. Doesn't include connection fees, but those are a minority of the cost. Includes special energy taxes. But not sales tax.

For a real example, I'm on flat rate and if I use 1000 kWh my monthly bill will be 211 CAD (effective rate 0.21 CAD / 0.13 EUR per kWh) including taxes, connection, delivery, everything, but without subsidy. The amount I pay after the subsidy is applied would be less at 165 CAD.
