Ice/water instead of economizer, to make use off-peak electricity

Tesla has an idea of storing power in a bank not too sure how it works but it's being trialed, good I idea

Thanks Grizzly and cadwaladr. The factory has done most of the standard sorts of things already. I think they are already cooling the glycol down a bit more at night, but they also get cheap off-peak electricity over the weekends and would like to take advantage of this as well and make ice then and use it later. There is also a limited amount of cooling that you can store in the glycol because it is just sensible heat, while if could freeze water you get the latent heat storage and could store lots of cold over the weekend. Has anyone else had experience using ice water instead of an economizer? Thanks again.
