Your rental gensets are only as reliable as the supplier who backs them. In planning for temporary power, find a rental dealership that has the equipment you need and a staff qualified to solve your problems and service the machines.

Visit the dealership to get to know the people you’ll need to rely on during scheduled shutdowns and emergency power outages.

Supplier selection criteria could include:

INVENTORY
The supplier should have all necessary equipment in stock – gensets and accessories – or be willing to commit to getting it on demand. Suppliers who do not have the equipment available in the region must have the capability to import it in an emergency.

SERVICE AND SUPPORT
The supplier should be willing to deliver the gensets and, in some cases, additional equipment including power cables, transformers, and more. In addition, suppliers should train local personnel in the equipment operation or, if necessary, provide staff for operation, service, and maintenance.

LOCATION
At a minimum, the supplier should be strategically located to serve major population centers. The ideal supplier will have multiple locations from which to deliver equipment and dispatch support staff.

EXPERIENCE
Longevity in business can be a good indicator of a supplier’s reliability. Suppliers should be willing to discuss their track record in delivering and installing equipment under tight deadlines, as well as their experience in emergencies. Reputable suppliers will always provide references.

TERMS
When renting gensets for emergencies, it is not always possible to secure an absolute guarantee for the availability of the equipment. However, some suppliers offer contracts that provide a “right of first acceptance.” In this arrangement, a party pays the supplier a retainer fee for an allocation of specified equipment. In return, the supplier agrees not to release that equipment to another entity without the first party’s consent.

Here are basic questions to ask:

• What is the kilowatt (kW) range of your genset rental fleet?
• Can you deliver immediately? If not, how long will it take?
• What if I need a genset in the middle of the night or during a holiday?
• Who supplies the fuel?
• How are your rental contracts structured? How flexible are they?
• Have you ever rented gensets to customers in my industry?
• What equipment/manpower do I need to provide?
• What technical service/support do you offer?
• How do I know my rental units are reliable?
• What happens if a genset I rent goes down?
• Do you have cables and other equipment I may need?
• Can you train my staff to hook up and operate the equipment? How long will it take?
• Can I obtain pre-approved credit so I can avoid delay during an emergency outage?
• Can you supply an operator?

There are many things to consider before the power goes off at your facility. 

How will the gensets get from the dealership to the facility?
Most dealerships deliver, but if you pick up the equipment yourself, you need to determine what size truck you will need. Most gensets are towed on semi-trailers and pull trailers. Others are skid-mounted and require lifting equipment for loading and unloading.

Where will you put the gensets?
The largest gensets measure 8 feet wide by 40 feet long (2.5 meters wide by 12 meters long). If tight quarters are a consideration, two or more smaller units will perform just as efficiently.

When it comes to accessory requirements, cables must be provided to connect the gensets to the building’s electrical system.
Transformers, load banks, bus bars, distribution panels, feeder plants, fuses, outlets, load centers, and other accessories may also be necessary.

How will you get cable from the gensets outside your building to electrical distribution boxes inside?
Consider installing a weatherhead or a cable access door in an outside wall of your facility that can be closed when not in use. Then, you won’t need to route cables through windows and doors that should remain shut during off-hours or inclement weather.

Can you store enough fuel close to the area where you plan to keep the gensets?
During extended genset runs, an auxiliary tank of fuel with capacity for at least 24 hours of run-time will reduce service calls from your fuel supplier.

Do you have people on staff who can hook up the gensets and check to ensure they will operate properly?
If not, make sure your dealership or an electrical contractor can do the hookup, or have the dealership walk your staff through the procedure.

Your dealership should have people on staff to help you plan out your fuel capacity, cabling needs, and on-site support.
