It's strange they chose those hours to promote. I would have thought they were "peak" and should have incentives to NOT use power then.
There are lots of ways to milk this. Put your fridge on a timer to cut out for the 2 hour block before the free power-- it'll coast no problem. Could do the same with electric water heaters, but look out for Legionnaire's Disease.
One of the computer companies in Massachusetts struck a deal with the PoCo back in the 1970s-- they cooled a "pool" overnight then used heat exchangers with that cold source during the day.
