Sizing Generator- Florida Nursery

[theplantman]

We have recently installed a new 20hp well that runs some critical watering areas on our farm. We want to have a standby generator installed, and in reaching out to generator/electrical companies, we are getting many different opinions on what we need. As a result, I have landed here to ask for advice. Here is what we have that we want to run, and the equipment that has been installed thus far:

Duke Energy 230 3-phrase power (I am told this is the highest we have available)
Pump Motor: Franklin 20hp pump model #236604 Franklin Motor Link (see three attaches pages on this motor)
Danfoss VLT AQUA Drive FC-202P18KT2ERH (see photo)
(18) Greenhouse Fans. They draw 1amp each, wired 110v.
(6) Very small irrigation timers.

The most complete quote, was a custom Diesel Generator made for this application. See attached quote.

We have gotten proposals from companies for 30kw, 40kw, 65kw with either Propane or Diesel. The issue is no consistency or agreement between electricians we have reached out to, so makes us worry about selecting a company/generator and it be to small and not work, or way overkill and burn up unneeded fuel. If there are any questions or further information I need to gather, let me know!

Thanks!

????
I thought that 230 3-phrase power died with the Dodo.
Do you have a niche open delta wild leg service?
Some guesses based on incomplete information:
Simple calculation based on 120/208 V service. 30 KVA.
Based on 230 V, wild leg service, 40 KVA.
Pump on DOL, 65 KVA.

In that size range, if you go diesel, I think you'll find that the 65kW unit burns less fuel at all power levels the smaller units are capable of producing.

Pricing is going to vary wildly.
