It seems they realize the scale of the problem now.
That's basic power generation.
It's usually always cheaper to save a watt than build a watt worth of generating capacity.
Or if you need heating it's usually cheaper to combust a watt worth of heat rather than power it.
People are often skeptical about the power company wanting to help them save energy. I'm not. The more people they can power up before they need to build another power plant the more money they make.
The easiest thing a food plant can do to save a watt is put most of the pumps and conveyers on frequency drives.
For example the 200hp pumps that feed water to the place where I work are on drives. One motor runs 24 hours a day 7 days a week, the second one kicks on a few times a day for maybe an hour or 3. Just this one motor and drive saves at least several hundred kwh every single day compared to running it full speed and regulating pressure with a valve like they did back in the old days.
I read a DoE report few months ago that said only 4% of industrial motors are on drives.
Ha, where I work about 80% of the motors are on drives. Power bill still comes in around $30,000 per day, I hate to think what it would be with out all those super high efficiency instrument controlled motors on drives.
