We Rent Diesel Generators Across Texas
800 kW Diesel Generator Rentals for Arenas, Port Terminals, and Treatment Plants
Popular Industrial Generator Brands We Have For Rent
An 800 kW generator is the largest unit in Stag’s 300-800kW class and the last stop before the megawatt fleet. Facilities rent at this size when the connected load is too heavy for a 750 kW unit to carry with margin, but does not yet justify moving to a 1000 kW machine and the heavier logistics that come with it. Each 800 kW diesel generator in our fleet is load-bank tested before it leaves the Dickinson, Texas yard. This page covers where the size fits, how it is specced, how it gets on site, and what to settle before requesting a quote.
What Size Power Generator Do You Need To Rent For Your Business?
Select the industrial generator size you need to rent. Choose sizes from 20kW up to 2,000kW. If we have it in stock, then we can hold the generator rental in our yard or ship the generator to your location.
Sites That Rent at the Top of the Class
Large venues, terminals, and treatment plants tend to land here. An arena or convention center needs lighting, HVAC, broadcast trucks, and concessions running together for a single event or through a prolonged outage. A port or marine terminal powers cranes, reefer racks, and gate systems that cannot sit idle while vessels wait. A wastewater or water treatment plant keeps blowers, pumps, and control systems running to avoid a permit violation.
Manufacturing plants, hospital campuses, and cold storage warehouses also rent at 800 kW during planned shutdowns and utility upgrades. If your peak load sits closer to 700 kW, our 750 kW diesel generator rental may fit more closely. If you need more than this class offers, our 1000 kW diesel generator rental is the next step, and our full generator size lineup shows the whole range.
Specs
An 800 kW unit sits at the ceiling of Stag’s 300-800kW class:
| Spec | 300-800 kW Class Range |
|---|---|
| Weight (with chassis) | 16,500 – 35,000 lbs |
| Amperage Output (480V) | 451A – 1203A |
| Voltage | 240/480V |
At 800 kW, expect weight and amperage at the upper end of this range. Exact voltage, phase, and connection type are confirmed against your switchgear before delivery. Our amperage chart and power calculator help with cable and breaker sizing ahead of time.
One Large Unit or Two Smaller Ones
At this capacity, a common planning question is whether a single 800 kW generator is the right structure or whether two smaller units in parallel would serve better. A single unit has fewer connection points, a simpler footprint, and one fuel tank to manage. Two paralleled units add redundancy, since a facility can keep half its load online if one machine needs service, and they allow capacity to be added or removed as demand changes.
Points that usually decide the question:
- Whether the site can tolerate any interruption if a single unit trips offline
- Pad space and cable routing for one machine versus two
- How much the load varies through the day, since two units can run one at light demand
- Rental duration, since long projects often justify the added coordination of paralleling
- Crane or heavy-haul access to the placement location
Our team walks through this decision with your engineer or facilities lead, and our power distribution equipment covers the panels, transformers, and cabling either option requires.
Starting Large Loads Without Tripping the Set
Chillers, blower motors, crane drives, and large pumps draw a sharp surge when they start, and several starting together can overload a generator that carries them comfortably once running. Sequencing matters as much as the nameplate rating. Soft starters, variable-speed drives, and staggered start schedules all reduce the surge the generator must absorb.
Details worth gathering before delivery:
- Horsepower and starter type of the largest motors on the load
- Whether variable-speed drives or soft starters are in use
- The order in which loads can be brought online
- Voltage and phase at the point of connection
- Switchgear location and the cable length needed to reach it
Fuel Supply for Long-Duration Rentals
A generator carrying a load near this size consumes diesel in volume, and a single trailer-mounted tank does not cover a multi-day deployment. We plan fuel delivery as part of the rental, with scheduled refills timed to the load profile you give us. For longer projects, external fuel storage can be added. Our fuel consumption chart shows expected usage at different load levels for budgeting.
Steady voltage and frequency from a diesel engine also protect UPS systems, drives, and instrumentation that react badly to fluctuation.
Delivery, Placement, and Setup
- Heavy-haul trailer delivery to a pad, lot, or yard, with route and clearance checked in advance
- Crane or rigging coordination when the unit must be set in a tight or elevated location
- Acoustic enclosures for sites near offices, patient areas, or residential neighbors
- Transfer switch compatibility for automatic backup at facilities with existing gear
- Remote monitoring so our technicians can track load, fuel, and engine health between visits
Every unit is weatherproofed for Gulf Coast heat, humidity, and heavy rain.
Rental Terms and Billing
Rentals at 800 kW usually run on weekly or monthly terms, since the projects behind them are planned shutdowns, extended outages, event seasons, or construction-phase power. Daily rates stay available for short bridging needs. Single-, double-, and triple-shift billing ties cost to the hours the unit runs rather than a flat continuous rate. Our rental pricing guide covers what else shapes a quote.
Typical Uses
- Arenas and Convention Centers: Event power, broadcast trucks, HVAC, and concessions.
- Ports and Marine Terminals: Cranes, reefer racks, lighting, and gate systems.
- Water and Wastewater Plants: Blowers, pumps, and control systems during outages or upgrades.
- Manufacturing: Production lines held online through planned utility work.
- Hospital Campuses: Imaging, surgical suites, and central plant equipment.
- Cold Storage and Distribution: Refrigeration and dock systems held at temperature.
Reserving Before Demand Peaks
Units at 800 kW are limited in any market, and storm season compresses availability across the Gulf Coast. Hurricane season runs June through November, and large facilities that wait for a forecast compete with every other operator for the same few machines. Booking ahead locks in the unit, the tie-in plan, and the fuel schedule.
Our hurricane contingency power plans secure equipment before peak demand. For failures at other times of year, our emergency generator rentals cover fast-turnaround needs.
Renting From Our Dickinson Yard
Our fleet runs from 20 kW to 2000 kW, with each unit load-tested before it ships. Operating from Dickinson, Texas puts us within a short haul of Houston, Texas City, Galveston, Freeport, and the Ship Channel industrial corridor.
- Diesel generators across the 20 kW to 2000 kW range
- Heavy-haul logistics coordinated for large units
- Shift-based billing matched to your schedule
- Cable, panel, and transformer support from one supplier
- Direct access to our team for load and tie-in questions

Why Call To Rent A Generator Before The Next Hurricane Season Begins?
Risks Of Waiting To Rent A Generator
Limited Availability
Rental programs often operate on a first-come, first-served basis. Availability may be limited during peak times.
Delivery Delays
Moving a generator takes time. If you don't have a generator near your site, then you may be missing out when a hurricane hits.
Surge Pricing
Renting a generator after a hurricane strikes may incur an increase in price as many rental companies are moving towards a "surge pricing" model.
