***Mods, please feel free to move this (to the "Oil & Gas - Production" forum?) if you feel this is not the correct forum for this post***
I have a client based in western Canada that is requesting a single natural gas genset to power a well pad consisting of:
Equipment will be running 24/7.
Equipment is 3-Phase 480V.
All pumping units & compressors with be on VFD's.
Clean pipeline quality fuel gas.
I set the two (2) compressors as non-intermittent loads.
I set the four (4) pumpjacks as intermittent loads due to the "on/off" nature of these devices.
The summary shows a peak of about 300kW and a running kW of ~275kW. However, SpecSizer recommended a 423kW G3412 even though it's only 65% utilized. Why wasn't a smaller genset suggested? Did I do something wrong or is the G3412 simply the smallest unit available that will do the job?
Any feedback would be greatly appreciated.
See below for my SpecSizer settings:
