Long-term "guaranteed" baseload is necessarily cost-plus (witness the comedy in the UK where the govt is reduced to asking EDF how much they want for new nukes). Renewables are inherently marginally priced, hence the need for minimum guaranteed prices.

Where renewables start to displace baseload, it would appear that you effectively need to nationalise the grid and the baseload plants (or contract it under strong central control).
