I used a graph from the Economist, which is itself based on IEA work (dating back from 2004), simply to have a basis for discussion, and to show that current prices per kWh are roughly in the same range.

I've seen numerous studies with various estimates of prices for kWh from various sources, inclusing some that try to include carbon costs (increasing the cost of coal and gas) and balancing costs (increasing that of wind).

This one (from Emerging Energy Research) is probably pretty close to my own experience and estimates for the US (with Europe seeing wind more expensive and nuclear less):

My experience of actual projects I've financed is that wind power will typically cost 3-6c/kWh to produce before taking into account the return on capital (ie profit) - ie long term O&M and debt service costs, depending on wind conditions and the date of construction (recent projects tend to have seen prices increase, like all other technologies, due to commodity prices and supply chain bottlenecks).

EDF's costs at in the 2-3c/kWh for nuclear, but costs for new investment, based on private sector financing, are likely to be significantly higher.
