When the power goes out suddenly, managing industrial applications, construction sites, hospitals, and data centres becomes difficult. A prolonged outage can interrupt production, affect critical equipment, disrupt communications, and create safety concerns.
An emergency power generator rental saves the day in such cases by offering power backup to keep your essential operations running while your utility power gets restored.
If you’re wondering how to rent the right sized emergency power generator, how much it’ll cost, and what safety considerations it needs, then this guide by Curtis Power Solutions is for you.
An emergency power generator rental is a temporary power system that you bring to your facility or job site when your normal power supply is unavailable or insufficient.
Unlike a permanent standby generator, you can use this rental generator for a specific period and remove it once the need has passed. This allows you to fulfill additional power needs without purchasing another permanent genset.
Temporary emergency power becomes important when an outage affects systems that cannot simply be shut down until the utility service returns.
Such situations where you may need an emergency generator rental include:

Choosing an emergency generator isn't simply about finding the largest unit available. The generator needs to match the electrical and physical requirements of your site.
You should consider factors like:
Required power output - Determine the total load that needs to be supported.
Critical loads - Identify which systems must remain operational and which can be switched off.
Starting loads - Motors, pumps, compressors, and other equipment can require more power during startup.
Voltage and phase - The generator must be compatible with the electrical requirements of the equipment being powered.
Fuel availability - Consider whether diesel or another fuel source is practical for your site and expected runtime.
Runtime - Longer outages require appropriate fuel storage and refueling plans.
Site access - Make sure there is enough room and suitable access for delivery, placement, cabling, and servicing of the genset.
Distribution requirements - Large facilities may need temporary distribution panels, transformers, switchgear, or other equipment.
Installation and support - Consider who will handle setup, connection, monitoring, maintenance, and refueling.
You can also read our guide for a comparison into diesel vs gas generators to help you choose the right fuel type.
Choosing the right sized power generator rental is crucial. An undersized generator may not be able to handle the required load and can become overloaded when additional equipment starts.
Start by identifying which equipment needs emergency power and determine its electrical requirements. You then need to account for both running loads and starting loads, particularly for motor-driven equipment.
You should also consider whether additional equipment could need power during the outage. But remember, oversizing a generator unnecessarily can increase rental, fuel, and operating costs.
For complex commercial or industrial applications, you can seek support for professional load assessment to determine the appropriate generator capacity and configuration you need.
Emergency generator rental can offer several advantages when permanent power is unavailable. The list of benefits that you get from using an emergency power rental includes:
The choice between an emergency power rental or purchasing one comes down to how often you need the equipment and how long you expect to use it.
We’ve tabulated some factors below that you should compare before choosing a rental vs buying a generator.
An emergency power rental may include more than just the generator itself. Depending on the provider and application, your emergency rental package may include generator delivery, equipment setup, electrical distribution equipment, power cables, transformers or other accessories, and fuel tanks and fuel management.
Your generator rental provider may also offer additional support for routine maintenance, remote monitoring, emergency technical support, and equipment pickup after your rental period is over.
The exact scope of your rental services varies by project, so it’s important that you review your rental agreement carefully before the equipment is dispatched.
Emergency situations can create pressure to restore power as quickly as possible. But this doesn’t mean you should forgo appropriate safety practices for generator installation and operation.
Here are some important safety considerations that you must keep in mind while setting up a rental generator:
Provide adequate ventilation - The generator exhaust contains carbon monoxide (CO), a colorless and odorless poisonous gas. That’s why they should always be positioned outdoors and away from doors, windows, vents, and other openings through which exhaust could enter a building.
Protect against electrical shock - Generators produce electricity with the same fundamental electrical hazards as utility power. Wet conditions, damaged cables, improper grounding, and incorrect connections can increase the risk of electric shock or electrocution.
Prevent electrical backfeed - Never connect a generator directly to a building's electrical system without the appropriate transfer equipment and qualified installation. Backfeeding can energize utility lines that your workers may believe are de-energized.
Manage fuel safely - Fuel should be stored and handled appropriately for the generator and site. You should shut down the generator and allow it to cool before refueling to reduce the risk of fire.
Avoid overloading the generator - The generator should be operated within its rated capacity. You should also monitor the loads throughout operation, particularly when additional equipment is brought online.
For complex temporary power installations, you should work with qualified professionals who understand the electrical, fuel, ventilation, grounding, and site requirements involved.

An emergency power generator rental can help you provide temporary electricity when your normal power supply or permanent backup system isn't available.
But the right solution depends on more than just the generator size, you also need to consider your critical loads, starting requirements, fuel supply, electrical connections, site conditions, and expected runtime.
By working with an experienced rental provider, you get the support not just for selecting the appropriate equipment but to keep it running efficiently too. Contact Curtis Power Solutions for your emergency or temporary power needs.
To know your accurate emergency power needs, make a list of equipment that you need, add all their running wattages, and add the highest starting wattage to it. For a safe margin, you can add an additional 20 % capacity.
Portable generators can run for 8 to 12 hours continuously on a single tank of gas while standby generators can run from 50 to 200 hours before they need a mandatory oil check or service.
Emergency generator rentals are usually delivered and set up in 2-4 hrs locally or on the same day. If you’re purchasing a large standby generator, it can take up to a week to reach depending on the distance to your location.
Yes, an emergency generator can power your entire facility depending on its capacity and how your building's electrical system is designed.
Whether a generator rental includes delivery and setup depends on the provider you choose and the size of your generator.
An emergency power generator rental offers power backup in case of an unexpected utility failure, natural disaster, or your primary system breaks down.
