Re: Powering the grid and providing backup?
I recall reading an interesting article a couple of decades ago - so it's not new.
The project in the article involved a factory where a sudden uncontrolled loss of power could cause environmental contamination - so they had a factory sized UPS to run the entire site (around 2MW IIRC). Having effectively been forced into the expenditure in order to be able to operate the plant safely, they then figured that it offered a peak lopping capability - and by using a small amount of the stored capacity, they could substantially reduce their maximum demand charges.
