Hopefully, a bit more modern than the 3MW SAGE setup. :-) http://q7.neurotica.com/Q7/All5DieselGenerators.jpg http://q7.neurotica.com/Q7/DieselGenerator.jpg
https://blog.equinix.com/wp-content/uploads/2015/01/Generator2.jpg Same idea, bigger scale :-) I think Equnix DC6/11 in Ashburn has ~40 megawatts of diesel generator. Two buildings connected. The way they work is they might have say Qty 6 x 3 megawatt generators, they will all fire up in an outage, sync up then the system will shed ones it doesn't need. Then if one were to go offline it can bring in another one. That is two buildings, Equinix has like 15+ in Northern VA area now. AWS has over 100. Then there are a bunch of other players like Cyrus and DRT and the like. That is a lot of Caterpillar generators! 6+ per facility, over 200 facilities in Northern VA alone. 350 E Cermak in Chicago, it's a beautiful building that used to be a printing company that printed Sears catalogs and phone books (ironic.) Now it's a data center, and it has 100 megawatts of generator power in house!! A nuclear reactor is 600 megawatts I think. It's pretty crazy. But look up the building, and look up the library in it -- totally Harry Potter esque.
