Generator Redundancy

Re: Generator Survey

I am trying to ascertain the range of generator coverage you all have? Until we added a new ED, we have been fortunate enough to be able to:

Power 100% of the hospital with generator power (fairly nusual I suspect?)

We have 2 - 750KVA generators, 1- can carry the load with a medium A/C load, therefore we essentially have redundancy, should one of them fail for any reason. With a heavy A/C load, we'd have to shed 1 or more transfer switches depending on the load.

When we added 36,000 sf for the new ED and education/admin addition, the wisdom of the engineers was to put this addition on a new, single, separate 550KVA generator, w/o a transfer switch back to our 2 original generators, therefore, should it fail, the ED has only Life Safety (lighting only), (we fed life safety back to to the original generators, just in case of

Here's my issue: I suspect we are all over the board on generator coverage ability, as well as redundancy? Therefore I need to know if my belt and suspenders concern is shared among you in your own shops. This new ED generator has failed to start 2x in test since February, therefore, I want to install a transfer switch to be able to power the ED, should the new ED generator fail (+/- $75,000 job). Can you answer the following questions, while identifying your hopsital for me?

1. What %, or level of coverage can your generator/s provide?

2. Do you have more than 1 generator?

3. If you have more than 1, can it pick up the load should the primary fail (how much redundancy capacity)?

4. Hospital Name:

Other comments are appreciated.!
