I think the innovative products they are coming up with for the grid are going to be very popular and in demand. If you read this article it states "To implement this storage system in a city like Toronto, Opathella says there would need to be hundreds if not thousands, of battery banks". I think the same could be said about the TESS and the IESS system they are supplying to London Hydro and Toronto Hydro.
