Utility & Capacity Planning Basics for Industrial Facilities
Sizing power, water, effluent and refrigerant loads correctly is the single fastest way to control both capex and opex.
Capacity and utility sizing decide whether a facility is efficient, over-built or forever short. Get them right and the equipment tender almost writes itself; get them wrong and no supplier can rescue the project.
Capacity planning starts from the demand curve, not from equipment catalogs. Model your peak day, your design day and your average day separately — most industrial facilities run at 40–70% of nameplate capacity in normal operation.
Utility loads — electrical, thermal, water, effluent, refrigerant, compressed air — should be sized against the design day, not the peak. Over-sizing utilities is one of the largest hidden costs in industrial capex.
Redundancy should be a business decision, not a default. Ask: what does one hour of outage cost, and what does N+1 redundancy cost per year? Answer the question in money.
Document the load calculation methodology in the tender pack. It gives suppliers a shared basis to price against and removes an entire class of post-award disputes.

Only for the shared infrastructure that is expensive to add later — main power incomer, water and effluent connections, site layout. Equipment itself is almost always cheaper to add in a second phase.
