That is the continuous duty rating.  All alternators are rated for
continuous duty. 90 amps x 14 volts equals 1.26 kw, which is what it's
designed for and can handle just fine.  Modern cars can easily use this much
energy with all the electronics on board (megawatt sound systems, charging
iPhones, running the GPS, Bluetooth, etc., just like we do in our Vanagons),
and the alternators are no different in design. The battery provides some of
the power, which means it's being depleted and continuously recharged in a
balancing act with the alternator.

Subject: Alternator continuous-duty rating?

Does anyone happen to know the continuous-duty amperage rating for the stock
kinda alternator found on the 1.9?
