What A Generator Rental Includes
A rental covers the unit, delivery, placement, connection, a load test before we leave, scheduled fuel, and collection when you are done. Our fleet runs from small towable units around 20kW, which suit a wedding marquee or a small remodel, up to 1MW trailer generators for construction sites and industrial work, all diesel except a handful of gas units for indoor-adjacent applications. Everything is Tier 4 Final certified, which public works contracts and air-quality-restricted sites require, and we carry sound-attenuated units for events where nobody should be able to hear the power supply. Renting makes sense whenever the need has an end date: construction generator rental before the utility energizes a site, event generators for a festival or a wedding, commercial generator rental while a permanent unit is being installed or repaired, and industrial generator rental for a plant shutdown or a seasonal peak. If the requirement turns out to be permanent, we will tell you, and the same crew installs commercial standby systems and home standby units when that is the better answer.

Why Rent From Us
Most rental complaints trace back to one of two things: the unit was sized wrong, or the fuel ran out. Sizing goes wrong when somebody adds up running watts and forgets that a compressor, a pump or a tower crane draws several times its running figure for the couple of seconds it starts. A generator that stalls every time a motor kicks is technically the right kW and practically useless. Fuel goes wrong when delivery is treated as the customer’s problem. We size off the equipment list rather than the square footage, we deliver and connect rather than dropping a machine at the gate, and scheduled fuel is part of the rate with remote monitoring on the tank level. For events we deliver early, place the unit out of sight and out of earshot, and stay reachable through the evening rather than clocking off at five.
- 20kW to 1MW towable diesel units, all Tier 4 Final certified for restricted sites and public works.
- Sound-attenuated units for weddings, film and events, quiet enough to sit near a ceremony.
- Delivered, placed, connected, load tested and collected, rather than dropped off at the gate.
- Scheduled fuel delivery included, with remote tank monitoring so nobody runs dry on a weekend.
- Daily, weekly, monthly and seasonal rates, plus pre-staged units for fire season.
- Cables, distribution boxes, spider boxes and transformers available on the same delivery.
Reasons To Rent A Generator
Renting beats buying whenever the requirement has an end date, and these are the jobs we see most:
Construction before the utility energizes
Raw lots, tear-downs, tenant improvements and phased builds where the service drop is weeks or months away. Construction generators run the tools, the trailer, the lighting and the lift, and the unit moves as the job moves.
Weddings and private events
Ranch venues, estates, beaches and vineyards with nothing like enough power at the panel. Wedding generators need to be quiet, hidden and delivered hours before guests arrive, and the load list is usually catering, lighting, sound and climate control.
Festivals, film and production
Event generators for stages, food vendors, lighting rigs, production trailers and camera departments. Film work in particular wants sound-attenuated units and a distribution plan rather than just a machine.
A permanent unit is down or not installed yet
Commercial generator rental bridging a repair, a replacement, or the lead time on a new install. For a business with refrigeration or a code-mandated system, that gap is the whole reason to rent.
Planned outages and utility work
Panel upgrades, service cutovers, transformer replacements and scheduled maintenance shutdowns. Renting for the window costs a fraction of losing a day of operations.
Fire season and shutoff staging
Businesses and properties inside the shutoff footprint pre-stage a unit for the season so power is already on site before the utility de-energizes. We monitor conditions and confirm the unit is fueled and tested before the wind arrives.

How A Rental Works
Four steps, and the first one is where the job is actually won.
1. Size it off the real load
Send us the equipment list or the critical load list. We calculate running kW and, more importantly, starting kW, then pick a unit with enough margin that it never stalls on a motor start. This is the step that decides whether the rental goes well.
2. Delivery and connection
Flatbed or tow delivery anywhere in the county. Our crew places the unit on firm level ground, lands the leads, ties the ground, runs a load test with your equipment on it, and walks whoever is on site through the panel and the shutdown before leaving.
3. Fuel and monitoring
Scheduled fuel delivery is inside the rate on multi-day rentals, and remote monitoring reports fuel level, run hours and any fault to us directly. We dispatch before the tank gets low rather than after somebody calls.
4. Collection
Call when the job or the event is done and the unit is collected within a couple of days, with the ground left as we found it. Long-term rentals go month to month with no term to sign.
Sizes, Trailers, Fuel Policy And Distribution
What people generally mean when they call about a rental, and the options underneath it:
Trailer generators and towable units
The workhorse of the fleet. A self-contained diesel unit on a road-legal trailer with an integral fuel tank, weatherproof enclosure and outlet panel, sized from 20kW to 1MW. It tows to the site, sits on its own feet and needs nothing but fuel and a connection.
Construction generator rental
Monthly rates, repositioning as the job moves, and distribution gear on the same delivery. Sized off the tools, the lift, the temporary lighting and the site trailer, with margin for the compressor or crane that starts hardest. Tier 4 Final certification is mandatory on most public works.
Event and wedding generator rental
Priced by the day or the weekend, delivered early, placed out of sight and downwind, and quiet enough that nobody notices it during a ceremony or a speech. We size off the caterer’s and the production company’s equipment lists rather than a guess, because both routinely need more than the venue expects.
Industrial and commercial rental
Larger units for plant shutdowns, seasonal peaks, utility work and covering a permanent machine under repair. Those come with a paralleling option, load bank testing where the application needs it, and a fuel contract sized to the run time.
Fuel policy
Single-day rentals come fueled and are returned as delivered. Multi-day and long-term rentals quote fuel separately, metered by actual use, with scheduled refill delivery included in the rate. Emergency same-day refills carry a trip charge because they sit outside the route. There is no environmental or fuel surcharge added at the end.
Cables, distribution and transformers
A generator alone rarely finishes the job. Camlock cables, distribution panels, spider boxes, temporary panels and step-down transformers all come from the same yard and arrive on the same truck, which saves a second vendor and a second delivery window.
Pre-stage contracts
For businesses in the shutoff footprint, we stage a unit on your property for the season, keep it fueled and tested, and monitor regional conditions so it is ready before the shutoff rather than after. Cheaper than an emergency rental during a regional event, when everybody wants a machine at once.
What A Generator Rental Costs
Rentals are quoted as a flat daily, weekly or monthly rate plus fuel. Roughly, by size tier:
- 20kW to 25kW, suitable for a wedding, a small event or a light job site: broadly $150 to $350 a day, with weekly and monthly rates far cheaper per day.
- 50kW to 100kW, covering a mid-size construction site, a festival or a small commercial building: roughly $350 to $800 a day.
- 150kW to 300kW, for larger sites, commercial buildings and production: usually $800 to $1,800 a day, with monthly rates substantially better per day.
- 400kW to 1MW industrial units: quoted individually, and almost always taken monthly or seasonally rather than daily.
- Rental length. Monthly is dramatically cheaper per day than daily, and the crossover is at about a week. Tell us the real duration rather than the optimistic one.
- Sound rating, distribution gear, delivery distance and fuel schedule, all of which are quoted up front rather than added at the end.
Every rental is quoted flat, including delivery, connection, load test and collection. If the requirement turns out to be permanent, we will price a commercial standby install against the rental so you can see where the crossover is, and the same comparison works for industrial units. If owning makes more sense than renting, generator installation, service and repair all come from the same crew.
Frequently Asked Questions
How much does it cost to rent a generator?
It goes by size tier and duration. A 20kW to 25kW towable unit for a wedding or a small job site is broadly $150 to $350 a day. A 50kW to 100kW unit runs roughly $350 to $800 a day. A 150kW to 300kW unit is usually $800 to $1,800 a day, and anything from 400kW to 1MW is quoted individually. Weekly and monthly rates are much cheaper per day than daily rates, with the crossover at about a week. Every quote includes delivery, connection, a load test and collection.
What kinds of events and situations need a rental generator?
Construction sites before the utility energizes the service, weddings and private events at ranch and estate venues, festivals, film and television production, farmers markets and food vendor rows, planned utility shutdowns and panel upgrades, plant shutdowns and seasonal peaks, businesses covering a permanent unit that is down for repair, and properties pre-staging power for fire season shutoffs. Anything with an end date is usually cheaper to rent than to own.
Is fuel included in the rental price?
Single-day rentals arrive fueled and are returned as delivered, with fuel included. Multi-day and long-term rentals quote fuel as a separate line, metered on actual consumption, with scheduled refill delivery included in the rate. Remote monitoring tracks the tank level so we dispatch before you run low. Emergency same-day refills outside the schedule carry a trip charge, and there is no environmental fee or fuel surcharge added at the end of the rental.
What size rental generator do I need?
Send us the equipment list rather than the square footage. We calculate running kW for everything on at once, then add the starting surge of the largest motor, which for a compressor, a pump or a crane is several times its running figure. A wedding with catering, lighting and sound is usually 20kW to 40kW. A mid-size construction site is 50kW to 150kW. A commercial building on critical load is 100kW to 300kW. Undersizing is the most common rental mistake and it shows up as a unit that stalls every time something starts.
How quickly can you deliver a rental generator?
Most rentals go out next day, and same day is often possible when the size you need is on the yard. Call in the morning and we will tell you honestly what is available. Larger units, sound-attenuated event units and busy spring and summer weekends book further ahead, so anything with a fixed date is worth reserving early rather than assuming.
Are your rental generators quiet enough for a wedding?
The sound-attenuated units are, which is why we use them for anything with a ceremony, a speech or a recorded performance attached. A standard construction-spec unit is not, and putting one behind a marquee is a mistake people only make once. We also place event units downwind and out of sight, and deliver hours ahead of guests so there is time to move anything that is not right.
