This guide delivers actionable insights into project power assessment, empowering you to make confident decisions. Following is how our operational power efficiency solutions protect your operations and maximize ROI

1. Understanding Industrial Power Requirements: The Foundation of Smart Selection

Decoding Your Power Demand Profile

Successful project power assessment begins with a comprehensive analysis of your electrical ecosystem. Industrial energy planning requires evaluating both obvious and hidden power consumers that collectively determine your facility’s total energy appetite.

Critical Assessment Questions:

  • Equipment Inventory: What machinery, HVAC systems, lighting, and auxiliary equipment will operate simultaneously?
  • Load Characteristics: Constant loads (manufacturing lines) or variable loads (intermittent equipment)?
  • Starting vs. Running Power: Motor-driven equipment demands 3-6x their running wattage during startup
  • Future Expansion: Will your operation scale within 12-24 months?

Saudi Arabia’s extreme climate places extraordinary demands on cooling systems, with HVAC equipment consuming 40-60% of total power. Summer temperatures exceeding 45°C mean your generator must reliably support intensive cooling loads.

The Mathematics of Power Demand Estimation

Step 1: Total Running Wattage – List every electrical device and sum simultaneous running loads

Step 2: Account for Starting Surge – Multiply the largest motor’s running wattage by starting coefficient (typically 3-6x)

Step 3: Safety Margin – Add 25-30% buffer for unforeseen loads and efficiency losses

Example Calculation:

Total Running Loads: 150 kW

Largest Motor Starting Surge: 45 kW × 5 = 225 kW

Subtotal: 150 kW + 225 kW = 375 kW

Safety Margin (25%): 375 kW × 1.25 = 469 kW

Recommended Generator: 500-550 kVA minimum

2. Generator Capacity Calculation: Converting kW to kVA Correctly

Power Factor

One of the most critical aspects of generator load calculation involves converting between kilowatts (kW) and kilovolt-amperes (kVA). These are the standard rating systems for generators.

The Essential Formula:

kVA = kW ÷ Power Factor

 

International Standard: Generators are rated at 0.8 power factor (80% efficiency)

If your power demand estimation reveals 400 kW total requirement:

  • Required Generator Rating: 400 kW ÷ 0.8 = 500 kVA

Power Requirement (kW)

Standard Rating 0.8 PF (kVA)

Improved 0.9 PF (kVA)

Poor 0.7 PF (kVA)

100 kW

125 kVA

3. Generator Type Comparison: Standby vs Prime Generators

The standby vs prime generators distinction represents one of the most consequential decisions in industrial generator selection.

Standby (Emergency) Generators:

Key Characteristics:

  • Primary Use: Emergency backup during utility outages
  • Annual Operation: Maximum 200-250 hours recommended
  • Load Capacity: 70% maximum capacity during startup; 100% for short durations
  • Typical Applications: Hospitals, data centers, commercial buildings, critical infrastructure

Prime Power Generators:

Key Characteristics:

  • Primary Use: Main power source in off-grid or unreliable grid locations
  • Annual Operation: Unlimited hours with proper maintenance
  • Load Capacity: Variable load 50-100%; average load should not exceed 70%
  • Typical Applications: Remote oil & gas operations, mining sites, construction projects, desert industrial facilities
Saudi Arabia Application Context

Vision 2030 initiatives have created unprecedented demand:

Standby Applications: NEOM development, Riyadh Metro, data centers, healthcare expansion

Prime Power Applications: Remote Empty Quarter drilling, Red Sea tourism construction, industrial parks during grid expansion
