They don't say that lower rates are "the sole reason why they are not making snow 24/7", let alone the only reason why ski resorts run their snow machines at night (which was the original claim). I don't know what fraction of a ski-resort's expenses go to power for snow-making. Do you? The fraction that goes to power goes to the question whether day-time vs night time actually makes a difference that matters. For example, saving 100% of 1% is only 1%. I doubt that a ski resort would risk pissing off customers to save 1%. For example, it may well be that day-time made snow is inferior, or that the transion layer from day-time made snow to night time made snow annoys skiiers. (IIRC, most natural snowfall is at night.)
