Imagine a storm rolls in faster than forecasted, within minutes, the entire grid goes down. Your crews stand idle on a construction site or maybe the critical systems in your hospital struggle to stay online.
Whatever the case, no one can afford to lose power and this scenario could very well be a reality in peak hurricane season. And although no one can control the weather or power outages, you can make sure you are prepared when the storm hits.
Wondering how? Through commercial generator rental services! They give you immediate, reliable power exactly when and where you need it. In this 101 guide by Curtis Power Solutions, we will discuss everything about commercial generators for rent. We will cover their benefits, cost-factors to consider, safety and maintenance steps, and how different industries benefit from rented generators.
So, let’s begin!

Renting vs Buying: Which is Best for You?

There are a lot of options in the market when it comes to generators, from diesel to natural gas, and propane generators; portable to non-portable ones. Each of these can either be bought or you can rent them. Wondering which is best suited for you - buying vs renting? Here's your cheat code.

Consider for how long you need the generator. Rent a generator in case of an emergency or for short-term needs (from a few days to months). However if you require the power backup for a longer duration, it is best for you to buy it.

Let’s go over how renting outweighs buying a generator:

  • Renting doesn’t require a high upfront investment.
  • No worrying about the maintenance and storage costs.
  • Offers scalability by upgrading as you grow.
  • 24/7 assistance from the  generator rental agency  as needed.
  • Transport, maintenance, and repair support.
  • Ensures compliance with global standards and the local building and zoning regulations.    

What is Included in the Generator Rental Package?

The generator rental generally includes the generator, its associated cables, and other parts for completing the setup. Confirm with your commercial generator rental agency beforehand about the services they provide with the generator system. 

Also, the knowledge of the key factors to consider before renting a generator is crucial to choose the best one for your business. At Curtis Power Solutions, in addition to the basic set up we also offer installation, transportation, and maintenance support. 

Which Factors Contribute to the Generator Rental Cost? 

There are a lot of factors including the size, capacity, and type of generator, etc. that contribute to the generator rental cost. This knowledge will help you understand which services are provided by the generator rental agency and which ones you need to take care of yourself.


Here’s what adds to your commercial generator’s rental cost:

  • Size and Capacity of the Generator

The size and capacity of the generator contributes the most to its renting cost. A generator with high capacity and more power output will definitely have a higher renting cost as compared to a smaller one. 

  • Generator Runtime 

The runtime or for how long you use the generator also decides its rental cost. Determine your needs well in advance before booking the generator. 

PRO-TIP: Avoid any last minute bookings and consult your rental agency to get the right-sized generator for rent.

  • Type of Fuel

The renting cost is also affected by the type of fuel that you need for the generator. A common query that arises here is diesel vs gas generators. Although diesel costs more and its price often fluctuates, it is more fuel-efficient than gas generators.

  • Delivery and Installation

While most generator rental agencies include the installation and delivery in the renting cost, some may charge you extra for it. Talk to your generator rental before making the final decision. 

  • Add-ons

You may also be charged extra for the additional accessories including power cables, extension chords, and transfer switches, etc. 

Industries that Rely on Generator Rentals  

Losing power is never a viable option for any scalable business. A lot of industries benefit from the commercial generator rentals, it is a clear winning strategy where you don’t invest much but still get the assurance of a constant and reliable power backup. 

Let’s take a look at which industries need power backup 24/7:

1. Healthcare Industry

With the primary goal to save lives and treat people, the healthcare industry requires essential equipment to run at all times. Power outages due to extreme weather or grid failures necessitate a partnership with commercial generator rentals to ensure there are no power failures.

2. Construction Sites

The temporary job sites of the construction industry often lack a stable power supply from the power grid. For running interrupted operations and securing the worker's safety it is important to have rented generators at the site for consistent power supply. 

3. Hospitality Industry 

The tourism and hospitality industry is central to a country’s economy. For continued operations of elevators, HVAC, and lighting it is crucial to ensure a power backup so nothing stops in case of a power outage. Rental generators are thus important for customer satisfaction and successful business operations.

4. Multi-unit residential complexes

From the basic lighting, to everyday appliances, and the central heating, everything runs on power in a house. An instant and reliable backup is also important to ensure the safety and security of the residents in a multi-unit residential complex. 

5. Retail

The retail industry too requires a reliable power supply to make sure there are no downtimes, spoiled inventories, or lost transactions. It is also important to ensure maintenance, security and to prevent equipment damage due to power surges.

6. Events and Entertainment  

Nobody likes disruptions, especially in an entertainment event and power is integral here to make sure there are no hiccups. The entertainment industry with a budget of sometimes even millions thus thrives on power backup to ensure their investment doesn’t go wasted. 

7. Data Centers

In the age of cloud computing and AI, data centers have become integral to a country’s economy. These data centers need a reliable backup to ensure everything runs seamlessly and there are no data loss or breaches.  

Now that you know how each industry benefits from a consistent power backup. Let’s understand why the generator's compliance to codes and standards matters and whether you need it while renting.

Do You Need to Ensure Compliance for Rented Generators?

There are various standards and codes put forth by organisations like National Fire Protection Association (NFPA), Environmental Protection Agency (EPA),and the local authorities for storing and using generators. 

Therefore, in addition to looking at the basic requirements and other cost related factors, it is also important to ensure you comply with the specific guidelines and codes for generators. Yes, even while renting. Wondering why this compliance matters?
Here’s why:

  • To Ensure Safety and Reducing Liability

Compliance is important to ensure safety from any electrical, fire, and health (Carbon monoxide poisoning) hazards. It also reduces the liabilities (in terms of any lawsuits, damage claims, and fines) for both the rental agency and the rentee. 

  • For Reliable Functioning

The compliance codes put checks on wiring, grounding, and maintenance, all of which enable reliable functioning of the rented generator. The regular testing and inspection of the generator unit also enhance the longevity of the system.

  • For Environmental Protection 

Complying to the EPA codes also aid in protecting the environment through the classification of different diesel generators, limiting the release of air pollutants. The US state of California has even stricter California Air Resources (CARB) standards.

  • To Avoid Legal Issues

Compliance ensures that you avoid any legal issues like fines, penalties, and the insurance being invalidated. It helps avoid costly downtimes due to removal of generators in high-risk institutions like hospitals and data centers.

Safety and Maintenance Guide for Rental Generators

Ensuring the safe operation, storage, and maintenance of generator systems is integral for a rented generator. This ensures you get the backup when needed and there is no risk to any business operations nor are there any safety issues. 

Here are a few pointers for your commercial generator rental’s safety and sound maintenance:

  • Follow the manufacturer’s guidelines for maintenance and safekeeping.
  • Ensure safe transportation of the genset.
  • Ground the genset to avoid any safety hazards in case of excess current.
  • The generator should be stored outside in an open space to minimise CO poisoning and fire hazards.
  • Ensure that the electrical safety of the genset is well maintained.
  • Follow a weekly, monthly, and annual maintenance regime to ensure safe and reliable working.
