I have been asked to look for ways to cut cost on energy where I work. We have 24- 2000KVA 13.2/480 subs and 4 -13.2/2400 5000 KVA Subs. The 4 2400 volt subs are only loaded at about 40 % of their rated KVA. I am looking at moving the secondary feeder breaker and cable to the xformer setting beside it and shutting down 2 of the 4. This is based on if it will it be cost effective. I am trying to determine the value on cost saved by having 2 subs fully loaded vs. 4 subs loaded at less than 50 %. I have read that running a sub at 50 % load cost alot extra on VARS wasted. Thanks for any help on determining the lose loaded at 50%.
