I think "baseload" has almost lost its meaning in these discussions.

Renewables have been displacing traditional baseload generation for years. What grids actually need is reliable dispatchable capacity, peaking power and firming.

People keep bringing up winter cold spells and claiming we need "baseload" to handle them, apparently without realizing that nuclear never solved those demand peaks either.

Historically that's been the job of dispatchable generation.

Baseload is the minimum level of demand.
