Could have been a 16/20/25 but that is not what the OP stated and is really irrelevant since that is not the question asked.
Amusing, but the question was about a capacitor application.
Woulda,shoulda, coulda!!!!
No need to be smarmy with your responses.
To stick to the OP - my answer, based on what limited information was given, and my experience as an engineer, is that it is not practical, or good engineering practice to add that much load to the transformer by adding capacitors with the assumption that you can achieve a system pf of 1.0. Its a good exercise for a textbook problem, but not a real world application. It is not good practice to try for a pf greater than 0.95 lagging.
Just for added value, everybody does realize that this would be a medium voltage electrical system greater than 4160V and the capacitors involved would need to be similar to the EATON MV-AutoVAR.
Carry on!
