For base load one obvious reason to be sceptical is that in country A you may find that a generation technology is "base load" and so we can't possibly throttle it up or down, that's just how it works, and then in country B the very same technology is indeed throttled up and down as needed.

The UK has a lot of combined cycle gas burners. You will sometimes see US claims that these generators are only baseload and it wouldn't make sense to throttle them up and down. Over the course of an ordinary day in Britain you might see power output from these "baseload" generators vary between 2GW and 20GW and it's no big deal.

gas turbines last much longer when run at constant optimal RPM than when constantly varying.

My naive presumption is that the gas turbines do run at constant RPM, but vary the fuel use to deliver more torque and hence energy?

Maybe just wrong though :P

I'm not sure. I do not that gas peaker plants that have to be started and stopped a lot wear out very fast.
