They do. Natural Gas fueled generators are practical at 50MW capacity. GE basically sells a 747 engine (CF6) driving a generator, known as the LMS6000

I understand that gas turbines can produce that kind of power, in fact I used to work on some pretty large turbines and turbo generators in the 500-1000MW range. However they aren't used as backup generators where they have to be online in a minute. These are the types of generators I was referring to, https://powergen.gepower.com/products/reciprocating-engines/...

More batteries to get over the slower generator startup time, and likely quite a few smaller generators to do the best they can to keep the batteries going if the big generator is slower than expected to startup that day.

That's probably the most awesome thing I've heard tonight.

That is cool. Wonder what the efficiency of one of those will be.
