Underfrequency load shedding (UFLS) is a widely accepted effective measure to repress further frequency drop. Most of UFLS schemes use pre specified steps based on measured frequency to shed load.

Last year I was slow dancing with an old friend to some dreadful tune at her gaff, having put away a shed-load of drink, and we found ourselves having a bit of a tonsil tease.

We can also use 'shed load' or 'shed loads' without 'of' if it's clear what we're talking about. Like in these examples.
