Budget electrical studies by protective device and bus count, not by square footage. A single small commercial building under 20 panels typically runs $2,000 to $10,000; a school or retail center around 50 panels runs $10,000 to $25,000; hospitals, plants, data centers, and campuses start near $25,000.
Why are electrical studies required on a project?
Most project specifications across commercial, industrial, healthcare, and educational sectors mandate various electrical studies:
- Arc Flash Analysis – required by NFPA 70E and OSHA for worker safety.
- Short Circuit Study – ensures equipment can withstand fault currents.
- Protective Device Coordination Study – verifies breakers and fuses operate selectively.
- Load Flow / Voltage Drop Analysis – checks that circuits are properly sized and voltages stay within limits.
Owners, engineers, and AHJs require these studies to demonstrate compliance and reduce liability. Contractors who don't include them risk delays, change orders, and even OSHA exposure.
What Drives the Cost of an Electrical Study?
Not all studies are created equal — here are the biggest cost drivers:
- Size of the system – More equipment (switchgear, panels, transformers) means more buses in the model.
- Level of detail required – Federal/healthcare projects often require highly detailed studies. Smaller commercial jobs may be simpler.
- Arc flash labeling – How many pieces of equipment need hazard labels?
- Utility data – Coordinating with the utility for available fault current sometimes adds time.
- As-built vs. new design – Renovations often require site visits and data collection, while new construction studies may be modeled off design drawings.
How much should you budget for electrical studies?
Every project is different, but here are general ranges you can use for budgeting:
- Small commercial (one building, <20 panels): $2,000 – $10,000
- Medium facilities (schools, retail centers, ~50 panels): $10,000 – $25,000
- Large/complex projects (hospitals, plants, data centers, campuses): $25,000+
Pro tip: Always check the spec. Some contracts call for all four studies, while others only require short circuit + coordination. For a budgetary range built on your actual device count, use the study cost calculator.
How do you subcontract electrical studies the right way?
When subcontracting electrical studies:
- Choose a qualified partner – Look for a firm that specializes in power system studies (not just general engineering).
- Verify deliverables – Ensure they'll provide reports, updated one-lines, and compliant arc flash labels.
- Coordinate early – Bring your subcontractor in during design to avoid late surprises.
- Protect your liability – The right partner documents NFPA 70E compliance so liability doesn't land back on you.
Why do contractors partner with PowerSafe Engineering?
At PowerSafe Engineering, we work directly with electrical contractors to:
