Base load is marketing term for electricity supply which cannot economically follow the demand curve and is only affordable if you can use a constant supply of it. It's not a feature, it's a bug. What you want is dispatchable power.
The term vaguely makes sense if there are sources of electricity that output a constant supply that are cheaper than the dispatchable sources of power. Like nuclear was supposed to be (but in the end is not). Or in some very specific locations hydro (without a reservoir) and geothermal are. But as often bandied about as a "type of power that must be filled" it simply doesn't exist. The type of power that must be filled is dispatachable power, everything else is just "well what cheap non-dispatchable sources can we use to avoid using more expensive dispatchable power".
