Commercial Diesel Generators

Get the right genset for your application

A commercial diesel generator plays a critical role in your business continuity plan. By providing backup or emergency power to your building during a power outage, commercial standby generators enable critical facilities like elevators and security systems to continue operating. Standby generators also minimize business and data losses that arise from computer system failures.

However, estimating what size diesel generator for commercial use you need depends on a number of factors. Before you proceed with your commercial generator purchase, you'll need to consider the needs of your business and the technical constraints of your building first.

Why proper generator sizing matters

Commercial backup generators provide power to a number of critical safety systems that operate during an emergency, including fire alarms, fire pumps, security systems and emergency lighting. Different buildings require different levels of backup power to keep these life-saving systems operational in the event of a blackout.

This is why most large-scale commercial generator installations require an engineering plan and an engineer's supervision to ensure compliance with National Electrical Code (NEC) and National Fire Protection Association (NFPA) requirements in the United States. Beyond regulatory compliance, improper sizing of a generator can also lead to a host of other problems.

Generators that are too large may cause:

  • Damage to electrical systems
  • Unnecessary operational expenses
  • Inefficient power production

Generators that are too small may cause:

  • Generator damage or overheating
  • Insufficient or unreliable power
  • Critical facilities and security system failures
