Having in a previous life installed a 400Kwp Solar array onto a cold storage facility, I know well the phenomenal energy demand for refrigerated retail, transport and storage. This looks a brilliant solution to shift the demand and usage, beyond just time-shifting electricity demand. It would be interesting to see the numbers. 

Whilst we're still not seeing any real level of take up in energy storage at the C&I scale, this could be something to kick start the appetite. Just as my 400kwp solar array was at the time the largest rooftop solar in the north of England, and one of the early fully funded PPA projects, and is now just a small array in the great scheme of things. We need this sort of innovation and reference project, as we sure have a significant retail/cold storage electricity demand to address in Europe.
