Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

Oh, a lot of the central-forecast costs just reflect the prejudices of the UK government, and aren't particularly useful.

To take one extreme example: the implicit levelised cost of nuclear in the model, is less than the value of exports.

Which means that in any scenario, you can decrease the total cost to UK plc, by building surplus nukes.  Nukes for power export are programmed to represent net cash earners, effectively having negative whole system cost.

There are several reasons for this.  Insurance costs are included for renewables, but not for nuclear.  Nuclear central costs and plausible build rates are very optimistic. So levelised cost comes out at under 7p/kWh.  And the value of exports is set at 7.32p/kWh. (cells F99-O99, sheet VII.a)
