Generator FAQs: Your Complete Guide to Standby, Portable, and Industrial Power

Several factors can impact the size of the generator you need, including total electrical load, starting currents, runtime expectations, and whether the generator will support just essential systems or full operations. Industrial generators and commercial generators are typically sized through a detailed load analysis rather than estimates.

ESSE works with customers to evaluate current and future power needs, ensuring the selected generator provides adequate capacity without overspending on unnecessary size. For complex systems, engineering-based sizing tools help determine the right solution for standby, prime, or continuous power applications.

Deciding between diesel, natural gas, or bi-fuel generators depends on site conditions, fuel availability, emissions requirements, and runtime expectations. Here are some general guidelines:

• Diesel generators are commonly used for industrial backup generator applications due to their durability, efficiency, and high power density.
• Natural gas generators offer cleaner operation and extended runtime where utility gas is available.
• Bi-fuel systems provide flexibility by allowing operation on multiple fuel sources.

There are many generator solutions available to meet NFPA requirements, including NFPA 110, as well as other applicable standards such as ISO and IEC. Compliance depends on the generator configuration, fuel system, controls, and installation details.

At ESSE, we support customers beyond basic compliance, helping ensure generator systems align with industry regulations, local codes, and operational requirements.

Yes. Remote monitoring improves reliability by providing real-time insights into generator status, alarms, fuel levels, and performance. Monitoring systems allow issues to be addressed before they become failures, reducing downtime and extending equipment life.

Remote monitoring is especially valuable for industrial generators, commercial facilities, and multi-site operations.

Custom backup power systems are designed using advanced engineering tools such as Generac’s Power Design Pro™. These tools help model loads, select suitable equipment, and design systems tailored to specific applications.

ESSE’s engineering team supports custom designs for standby, prime power, and integrated systems connected to utilities or operating independently.

Generator upkeep requires a proactive maintenance plan that includes inspections, load testing, fuel system checks, and preventive service. Regular generator maintenance reduces the risk of failure and ensures compliance with operational standards.

ESSE offers maintenance programs and service support designed to keep generators ready when they are needed most.

ESSE services any industrial generator, regardless of size or brand. Whether you are supporting legacy equipment or mixed fleets, trust ESSE for expert generator maintenance and repair services to keep power systems running reliably.

Some applications require more than a standard generator. ESSE specializes in custom power solutions, including integrated ecosystems that combine generators, utility connections, and additional technologies to deliver resilient, scalable power systems.
