Engineering P&C cost percentage of new Substation

[rockman7892]

Was interested in seeing if anyone has any experience, standard or ballpark estimates for what percentage of overall substation project cost the protection & control design engineering amounts to?

Looking for some rough estimates for familiarity

Thanks

Can't help with numbers; all I can say with certainty is that the combined cost of repairing electrical faults and the associated "down time" and production loss generally far exceeds the cost of a well-designed, installed, commissioned and maintained equipment and systems protection and control scheme.

That's one way to sell doing it correctly right from the get-go.

In most substations, other than the transformer, capacitor bank, switches, and bus, and/or reactor, everything is P&C.
There would be no need for most of the conduits, control cables, PT's and CT's, switchgear, and control building, if it were not for P&C. To go more, even switches are for control. Same with metering.
So just about everything that is not Civil engineering is P&C. Even the Civil that is associated with breaker and switches is P&C related.
