Arc Flash & Power System Studies
Arc Flash Study Quote & Cost | Short Circuit & Coordination Study Services
A clear guide to arc flash study quote and arc flash study cost, short circuit study services, protective device coordination study, and incident energy analysis—and how to get 2–3 qualified bids for power system studies services.
What Is an Arc Flash Study?
An arc flash study evaluates the risk of arc flash at each piece of electrical equipment in your facility. It uses short circuit and coordination data to calculate incident energy (cal/cm²) and arc flash boundaries, so you can apply NFPA 70E–compliant labels and select the right PPE. When you request an arc flash study quote, you’re typically asking for:
- Short circuit study — fault currents at key points
- Protective device coordination study — settings and selectivity
- Incident energy analysis — arc flash hazard at each equipment location
- Labels and documentation (and sometimes one-line updates)
Understanding arc flash study cost starts with scope: panel count, voltage levels, and whether you need only labels or full power system studies services including coordination and short circuit reports.
Short Circuit Study Services
Short circuit study services calculate available fault current (e.g., bolted three-phase and line-to-ground) at each bus or panel. These numbers drive equipment withstand ratings, coordination, and arc flash calculations. Without an accurate short circuit study, incident energy analysis and protective device coordination study results are unreliable.
Providers of power system studies services typically perform the short circuit study first, then use the results in coordination and arc flash software (e.g., SKM, ETAP, EasyPower). When comparing arc flash study quote options, confirm that short circuit and coordination are included if you need full documentation—not just labels.
Protective Device Coordination Study
A protective device coordination study ensures that breakers and fuses trip in a logical order (selectivity) so that a fault is cleared by the nearest device, minimizing outage scope and improving safety. Coordination curves and settings are often delivered alongside the arc flash report and are part of comprehensive power system studies services.
Many facilities bundle a protective device coordination study with their arc flash study so that one provider has full system data. That can improve arc flash study cost efficiency and consistency of deliverables.
Incident Energy Analysis
Incident energy analysis is the step that converts short circuit and coordination results into arc flash hazard levels (incident energy and arc flash boundary) at each equipment location. Outputs drive NFPA 70E table selection or calculation-based PPE and approach limits, and appear on arc flash labels.
When you get an arc flash study quote, the deliverable set should explicitly include incident energy analysis (and labels). If your one-line or panel data is outdated, many providers will recommend updating as-built electrical drawings first so the study is based on accurate information—reducing the chance of under- or over-labeling.
Arc Flash Study Cost: What Drives It?
Arc flash study cost varies with:
- Panel count — more panels mean more labels and more analysis
- Voltage levels — low voltage vs medium voltage, and multiple voltage levels
- Scope — labels only vs full short circuit, coordination, and report set
- Data quality — accurate one-lines and panel schedules reduce field time and rework
- Timeline — rush delivery can increase cost
Getting 2–3 bids for your specific scope (panel count, voltages, deliverables) is the most reliable way to compare arc flash study quote and arc flash study cost. Use a short questionnaire so providers quote on the same basis.
Example Costs: Arc Flash Study (Ballpark Figures)
The figures below are illustrative ranges only. Actual arc flash study cost depends on panel count, voltage levels, whether short circuit and coordination are included, region, and data quality. Use them to set expectations; get 2–3 arc flash study quote options for your specific scope.
| Scope | Typical description | Example cost range (USD) |
|---|---|---|
| Small | 10–25 panels, low voltage only; arc flash labels + short circuit; you provide one-lines or minimal field verification. | $3,000 – $8,000 |
| Medium | 50–100 panels, LV; full study: short circuit, protective device coordination, incident energy analysis, labels; one site visit; report set. | $12,000 – $25,000 |
| Large | 150+ panels, multi-building or campus; low and medium voltage; full power system studies (short circuit, coordination, arc flash); multiple site days; full report and label set. | $30,000 – $75,000+ |
Bundling with an as-built one-line update often adds roughly $5,000–$20,000+ depending on panel count but can reduce total cost versus separate engagements. Rush delivery or model handoff for future updates may add 10–20%.
Standards & Compliance: Basis for Arc Flash Studies
Power system studies services and incident energy analysis are driven by standards that define methods and compliance expectations. Key references include:
- NFPA 70E (Standard for Electrical Safety in the Workplace) — defines the requirement for an arc flash risk assessment and the use of incident energy and arc flash boundary to select PPE and establish approach limits. Arc flash studies and labels are the primary means of meeting this requirement.
- IEEE 1584 (Guide for Performing Arc-Flash Hazard Calculations) — the industry standard for calculating incident energy and arc flash boundary. Reputable arc flash study providers use IEEE 1584 (2018 or later) or the method referenced in NFPA 70E; confirm which revision and method your provider uses when you get an arc flash study quote.
- OSHA 1910.303 and 1910.332 — OSHA enforces electrical safety and training; they look to NFPA 70E as a consensus standard. Accurate incident energy analysis and labels support employer due diligence and worker protection.
- NFPA 70B (Recommended Practice for Electrical Equipment Maintenance) — recommends that electrical system documentation, including short circuit and coordination studies, be maintained and updated. A protective device coordination study and updated one-lines support 70B compliance.
- NETA (InterNational Electrical Testing Association) — NETA standards and certification are often referenced for acceptance and maintenance testing; coordination and arc flash documentation complement NETA testing programs.
When comparing arc flash study cost and arc flash study quote options, ensure the provider states compliance with NFPA 70E and use of IEEE 1584 (or the NFPA 70E calculation method) for incident energy analysis.

Arc flash study cost depends on panel count, voltage levels, facility size, and whether short circuit and protective device coordination studies are included. Commercial and industrial projects often range from a few thousand to tens of thousands of dollars. Getting 2–3 bids based on your scope is the best way to compare arc flash study quote options.
What is a short circuit study?
A short circuit study (short circuit study services) calculates fault currents at key points in the electrical system. Results are used for equipment ratings, coordination, and as input to arc flash incident energy analysis. It is typically performed with a protective device coordination study and arc flash analysis as part of power system studies.
What is incident energy analysis?
Incident energy analysis determines the thermal energy (cal/cm²) that could be released in an arc flash at each piece of equipment. Results drive NFPA 70E PPE requirements and arc flash label content. It is a core deliverable of an arc flash study and is based on short circuit and coordination data.
Do I need updated one-line diagrams before an arc flash study?
Accurate as-built one-lines and panel data improve study accuracy and reduce field verification time. Many providers offer a bundle: update as-built electrical drawings first, then perform the arc flash and short circuit study. If your drawings are badly out of date, expect recommendations to update them.
How long does an arc flash study take?
Typical turnaround is a few weeks to a few months depending on panel count, site access, and data quality. Rush options exist but can increase arc flash study cost. Clarify timeline when requesting your arc flash study quote.
What software do arc flash study providers use?
Common platforms include SKM Power*Tools, ETAP, and EasyPower. All support short circuit study, protective device coordination study, and incident energy analysis. When comparing arc flash study quote options, ask which software is used and whether you will receive the model for future updates or only PDF reports.
Is IEEE 1584 required for incident energy analysis?
NFPA 70E references IEEE 1584 as the preferred method for calculating incident energy and arc flash boundary; many jurisdictions and clients expect studies to follow IEEE 1584 (2018 or later). Confirm with your provider that the arc flash study uses IEEE 1584 or the method cited in the current NFPA 70E.
